The three-dimensional scene simulation apparatus 10 and the three-dimensional scene simulation method of the present application can be divided into two specific embodiments, and the two embodiments will be described below, respectively. It should be noted that modifications, or alternatives, made by those skilled in the art in light of the two embodiments of the application are also within the scope of the application.
Embodiment one:
referring to fig. 4, a three-dimensional scene simulation apparatus 10 according to a first embodiment of the present application is provided for simulating a configuration of a target object in a three-dimensional model of a current scene in real time. In this embodiment, the current scene is a home scene, and the target object is furniture to be placed in the home.
The three-dimensional scene simulation device 10 comprises an information acquisition module 12, a sensing module 13, a modeling module 14, a memory 15, a coupling module 16, an interaction module 17 and an application module 18 which are connected through a bus 11. The modules/modules of the three-dimensional scene simulation device 10 interact with signals and data through the bus 11. The information acquisition module 12 is configured to acquire three-dimensional data of a scene to be simulated and three-dimensional data of a target object to be configured in the scene. In the first embodiment of the present application, the information acquisition module 12 is configured to acquire three-dimensional data of furniture and three-dimensional data of home furnishing.
The information acquisition module 12 may acquire three-dimensional data of the target object from a server of the merchant over a network. For example: the information module 12 may further comprise a search unit 122 and a download unit 124. The searching unit 122 searches for a desired target object from the merchant's website according to the size data of the preset target object. The download unit 124 downloads and saves the three-dimensional data of the selected target object in the local memory 15.
The information acquisition module 12 may also directly sense three-dimensional data of the scene or the target object through the sensing module 13. For example: the information acquisition module 12 may acquire corresponding three-dimensional data by capturing a scene or a target object in front of the scene with a three-dimensional camera provided on a portable terminal such as a mobile phone.
The sensing module 13 comprises a three-dimensional camera. The sensing module 13 is configured to process the output data of the three-dimensional camera to obtain three-dimensional data of the target object and/or three-dimensional data of the scene, and transmit the three-dimensional data of the target object and/or the three-dimensional data of the scene to the information obtaining module 12. In this manner, the information acquisition module 12 is enabled to acquire three-dimensional data of a target object and/or three-dimensional data of a scene.
The three-dimensional camera is used for sensing three-dimensional data of a photographed object. The principles Of the three-dimensional camera may be based on structured light, binocular vision, or Time Of Flight (TOF), without limitation. It can be understood that, since the three-dimensional camera can sense three-dimensional data of the object in space, a three-dimensional model of the target object and the scene can be reconstructed according to the sensed three-dimensional data in the same proportion, and the real configuration situation of the target object in the scene is simulated.
Specifically, the user himself or a designed robot or other equipment can hold the three-dimensional camera to sense complete three-dimensional data of a scene or a seen target object according to a plurality of preset angles. Or, at a plurality of preset positions of the scene to be simulated, such as corners of an indoor space ceiling, a plurality of three-dimensional cameras are correspondingly erected to sense complete three-dimensional data of the scene, and the number of the three-dimensional cameras is not particularly limited. The information acquisition module 12 performs denoising, splicing, matching, optimizing and other processes on the three-dimensional data sensed by the three-dimensional camera, and stores the processed three-dimensional data into the memory 15 for standby.
It will be appreciated that the sensing module 13 may also include a color camera, such that color information of the scene and the target object may be obtained by the color camera. The color three-dimensional model of the scene and the target object constructed by combining the color information acquired by the color camera and the three-dimensional data acquired by the three-dimensional camera can be more realistic.
The memory 15 may store three-dimensional data of the home and three-dimensional data of the furniture for the user, so that the modeling module 14 may read the required three-dimensional data from the memory 15 when building the three-dimensional model. The memory 15 may be a storage medium provided on the local terminal device, or may be a cloud memory on a network.
The modeling module 14 is configured to establish a three-dimensional model of the target object and a three-dimensional model of the scene according to the three-dimensional data of the target object and the three-dimensional data of the scene, respectively. The three-dimensional data includes, but is not limited to, three-dimensional coordinates, laser reflection intensity, point cloud data of color information. The modeling module 14 may perform preprocessing, segmentation, triangle gridding, and mesh rendering on the point cloud data, so as to complete the establishment of the three-dimensional model. For example, the preprocessing of the point cloud data can be performed by filtering and denoising, data reduction, data interpolation and the like. Then, the point cloud data is segmented, so that the whole point cloud is clustered into a plurality of point clouds, and each point cloud corresponds to an independent object. Then, the point cloud can be triangulated by adopting a convex hull or concave hull algorithm, so that subsequent grid rendering is facilitated. After the space topological structure of the point cloud is obtained, the texture is mapped into the grid, so that the object is more vivid.
The coupling module 16 is configured to couple the coordinate system of the three-dimensional model of the target object into the coordinate system of the three-dimensional model of the scene through coordinate transformation operation, so as to simulate the configuration situation of the target object in the three-dimensional model of the scene. Specifically, the coupling module 16 is configured to perform a coordinate transformation algorithm according to a preset algorithm, such as: and the coordinate translation matrix and/or the coordinate rotation matrix convert coordinate data of the three-dimensional model of the target object in the self reference coordinate system into coordinate data of the three-dimensional model of the target object in the reference coordinate system of the scene.
It will be appreciated that the coordinate system of the three-dimensional model of the target object before it is not coupled to the three-dimensional model of the scene is a coordinate system established with the target object itself as a reference. The coordinate system of the three-dimensional model of the scene is a coordinate system established by taking preset points in the scene as reference objects. The three-dimensional model of the target object is coupled into the three-dimensional model of the scene, that is, the coordinate data of the three-dimensional model of the target object is converted into the coordinate data of the three-dimensional model of the scene, that is, the three-dimensional model of the target object is described and measured by using the coordinate system of the three-dimensional model of the scene.
The user may issue instructions via the interaction module 17 to couple the coordinate system of the three-dimensional model of the target object into the coordinate system of the three-dimensional model of the scene to control the coupling module 16 to couple the three-dimensional model of the target object into the three-dimensional model of the scene. The interaction module 17 includes, but is not limited to, a mouse, a keyboard, and a touch screen.
Specifically, in this embodiment, the user may first open the three-dimensional model of the home, and then drag the three-dimensional model of the furniture into the three-dimensional model of the home; or, the user can open the three-dimensional model of the furniture first and then drag the three-dimensional model of the home into the three-dimensional model of the furniture; alternatively, the user may select and open the three-dimensional model of furniture and the three-dimensional model of home at one time.
Of course, a user may couple multiple three-dimensional models of furniture to one three-dimensional model of home at a time; the three-dimensional model of the furniture can be coupled to the three-dimensional models of a plurality of households at one time; it is also possible to couple three-dimensional models of multiple pieces of furniture to three-dimensional models of multiple pieces of furniture at a time. The number of three-dimensional models of furniture and three-dimensional models of home furniture that are coupled to one another is not limited here.
The application module 18 is configured to configure a three-dimensional model of the target object in the three-dimensional model of the scene to simulate the configuration of the target object in the scene. In the first embodiment of the present application, the application module 18 is configured to configure a three-dimensional model of furniture in a three-dimensional model of home, so as to simulate the actual placement effect of the home, and provide a reference for the home design.
In the first embodiment of the present application, the application module 18 includes an interference unit 182, an interaction unit 184, and a measurement unit 186.
The interference unit 182 is configured to determine, according to a preset spatial attribute of three-dimensional data of a scene and a target object, an interference condition of a three-dimensional model of the target object when the three-dimensional model contacts an existing structure in the three-dimensional model of the scene. The spatial attributes include traversable attributes and non-traversable attributes. The interference unit 182 senses that two spatial coordinate groups having an impenetrable property are moved into contact with each other while restricting their mutual entry into the respective spatial regions, only along the contact surface therebetween.
It can be understood that the property of the spatial region corresponding to the object of the solid property and the existing structure in the scene is the non-penetrable property, and the property of the other spatial regions except the object of the solid property is the penetrable property. In this way, the three-dimensional model of the target object is made to be consistent with the real situation as is the configuration action in the field Jing Sanwei model. In a real scene, actions that are not possible with the target object should not be realized in the three-dimensional model of the scene either.
The spatial attribute of the three-dimensional data of the target object and the spatial attribute of the three-dimensional data of the scene may be preset by the user according to the actual situation, or may be automatically given to the attribute after the modeling module 14 determines the spatial area occupied by the object according to the sensed three-dimensional data, and then the user adjusts the spatial attribute according to the actual situation.
In one application scenario, after moving the three-dimensional model of the table along a direction perpendicular to the wall of the three-dimensional model of the home, the three-dimensional model of the table cannot continue to move along a direction perpendicular to the wall of the three-dimensional model of the home, because in an actual scenario, the table cannot pass through the wall. In this scenario, the two spatial coordinate groups with the non-traversable properties are the three-dimensional model of the table and the walls of the three-dimensional model of the home, respectively.
In another application scenario, the spatial coordinates of the table are preset as the non-penetrable attribute, the spatial coordinates above the upper surface of the table are preset as the penetrable attribute, the spatial coordinates of the barrel of the pen container are preset as the non-penetrable attribute, and the spatial coordinates of the barrel cavity of the pen container are preset as the penetrable attribute, so that a pen can be placed in the barrel cavity, but the pen cannot penetrate the barrel, and the pen container can be moved along the upper surface of the table, but the pen container cannot penetrate the table. Note that "table" and "pen container" in the examples refer to three-dimensional models of furniture in a three-dimensional model of home, rather than table and pen container in a real-world scenario.
In addition to the traversable and non-traversable properties, the spatial properties may also include elastic properties. It will be appreciated that for objects that may be deformed in a real-world scene, the passable and non-passable properties are not sufficient to describe their properties. The space region with elastic properties can deform to a preset degree according to the self-elasticity when the space region is contacted with an object with non-penetrable properties, so that the object with non-penetrable properties can enter the space with the original elastic properties within a preset range.
In one scenario, the spatial coordinates of the three-dimensional model of the window covering may be preset as elastic properties, and the deformation amount may be set according to the deformation capability of the window covering, and when the three-dimensional model of the window covering is pulled, the three-dimensional model of the window covering is stretched within the deformation amount.
In another scenario, the spatial coordinates of the three-dimensional model of the sponge wall may be preset as elastic properties, and the set variable may be set according to the deformability of the sponge wall. When the three-dimensional model of the table is moved along the direction perpendicular to the surface of the three-dimensional model of the sponge wall until the three-dimensional model of the sponge wall is contacted with the three-dimensional model of the sponge wall, the three-dimensional model of the sponge wall is recessed within the deformation amount range, and after the limit of the deformation amount is reached, if the three-dimensional model of the table is moved along the original direction again, the three-dimensional model of the table cannot be moved continuously, and the three-dimensional model of the sponge wall can maintain deformation in the limit state of the deformation amount. The deformation that the influence that comes to simulate the sponge wall in the reality scene received the pressure of desk like this takes place.
The arrangement of the elastic attribute can enable interaction between furniture and interaction between furniture and existing structures in the home to be simulated to be closer to reality in a three-dimensional model of a scene.
The interference unit 182 prompts the user to pay attention when it is judged that the interference condition has occurred. For example: the interference unit 182 reminds in a vibration, voice broadcast or highlighting or flashing display manner at the place where the interference occurs.
The interaction unit 184 is configured to receive a signal configuring a three-dimensional model of the target object, and change the position and morphology of the three-dimensional model of the target object in the three-dimensional model of the scene according to the signal.
In this manner, the user can change the position and morphology of the three-dimensional model of the target object in the three-dimensional model of the scene through the interaction unit 184. Specifically, a user may input configuration signals to the three-dimensional scene simulation apparatus 10 through the interaction module 17, the interaction module 17 including, but not limited to, a mouse, a keyboard, and a touch screen. For example, the user may drag or rotate the furniture three-dimensional model with a finger on the touch screen in the three-dimensional model of the home, and the interaction unit 184 changes the position and morphology of the furniture three-dimensional model in the three-dimensional model of the home according to the sensed finger movement.
The calculating unit 186 is configured to calculate relative position information between the three-dimensional model of the scene and the plurality of markers in the three-dimensional model of the target object, for example: distance, angle, curvature, etc. The marks include, but are not limited to, coordinate points, lines, or patterns.
Therefore, the user can configure the target object into an ideal state in the three-dimensional model of the scene, and then calculate the position information of the target object or the existing structure in the scene, which needs to be changed in order to achieve the ideal state, so that the user can modify and adjust furniture or home conveniently. Similarly, the user may select a measurement coordinate point to the three-dimensional scene modeling apparatus 10 through the interaction module 17, and after selecting the measurement coordinate point, the user may start measurement by clicking a completion button to cause the measurement unit 186 to start measurement.
For example, the user may select two measurement coordinate points at a time, and the interaction unit 184 may send coordinate values of the two measurement coordinate points to the measurement unit 186 after acquiring the two measurement coordinate points. The calculating module 186 calculates the distance between the two measuring coordinate points according to the coordinate values of the two measuring coordinate points. Alternatively, the user may select a plurality of measurement coordinate points at a time, and the interaction unit 184 may send the coordinate values of the plurality of measurement coordinate points to the measurement unit 186 after acquiring the plurality of measurement coordinate points. The calculating module 186 calculates the distance between each two measuring coordinate points or the angle between the two connecting points according to the coordinate values of the measuring coordinate points. The user can also calculate the position information such as the included angle by setting lines in the three-dimensional model of the target object and/or the scene through the interaction module 17.
The calculation module 186 may display the measured positional information in the associated three-dimensional model for reference by the user.
Note that, since the three-dimensional data of the real object and the scene is obtained, the position information of the relevant mark in the three-dimensional model of the object and/or the scene measured by the measuring module 186 is the real size of the object and/or the scene.
After seeing the measured distance value, the user can input adjustment data to the three-dimensional scene simulation device 10 to observe the placement condition of the three-dimensional model of the adjusted furniture in the three-dimensional model of the home. The interaction unit 184 is configured to obtain adjustment data of the three-dimensional model of the target object and adjust the three-dimensional model of the target object in the three-dimensional model of the scene according to the adjustment data.
Therefore, the user can decide whether to readjust or save adjustment data according to the placement condition of the three-dimensional model of the adjusted furniture in the three-dimensional model of the home. If the user feels that the three-dimensional model of the adjusted furniture is not placed in the three-dimensional model of the home, the three-dimensional model of the furniture can be continuously adjusted in a similar manner until the three-dimensional model of the furniture is placed in the three-dimensional model of the home. When the user feels that the three-dimensional model of the adjusted furniture is placed in the three-dimensional model of the home, the adjustment data can be saved to the memory 15 through the save button, and the adjustment data can be sent to the seller of the furniture through one key, so that the seller of the furniture adjusts the size of the furniture according to the adjustment data. Of course, if the user makes a plurality of adjustments to the three-dimensional model of the furniture, the interactive unit 184 may send the adjustment data of each adjustment to the memory 15, so that the user may reproduce a certain previous adjustment after making the plurality of adjustments.
The three-dimensional scene simulation apparatus 10 of the first embodiment of the present application may apply a three-dimensional scene simulation method. The above explanation of the embodiment and advantageous effects of the three-dimensional scene simulation apparatus 10 is also applicable to the three-dimensional scene method of the present embodiment, and is not developed in detail here to avoid redundancy.
Referring to fig. 1, a three-dimensional scene simulation method according to a first embodiment of the present application is used for simulating a configuration of a target object in a three-dimensional model of a current environment in real time. In this embodiment, the current environment is a home scene, and the target object is furniture that needs to be placed in the home. The three-dimensional scene simulation method comprises the following steps:
step S12: acquiring three-dimensional data of a target object and three-dimensional data of a scene;
step S14: establishing a three-dimensional model of the target object and a three-dimensional model of the scene according to the three-dimensional data of the target object and the three-dimensional data of the scene;
step S16: coupling a coordinate system of the three-dimensional model of the target object into a coordinate system of the three-dimensional model of the scene; and
step S18: a three-dimensional model of the target object is configured in the three-dimensional model of the scene to simulate the configuration of the target object in the scene.

Embodiment two:
referring to fig. 10, a three-dimensional scene simulation apparatus 10 according to a second embodiment of the present application is provided for simulating a configuration of a target object in a three-dimensional model of a current environment in real time. In this embodiment, the current environment is a home scene, and the target object is a robot that needs to move in the home.
Including, but not limited to, a floor sweeping robot, a floor mopping robot, and a window cleaning robot.
Similar to the first embodiment of the present application, in the second embodiment of the present application, the three-dimensional scene simulation apparatus 10 includes an information acquisition module 12, a sensing module 13, a modeling module 14, a memory 15, a coupling module 16, an interaction module 17, and an application module 18, which are connected through a bus 11. The information acquisition module 12 is configured to acquire three-dimensional data of a target object and three-dimensional data of a scene. The modeling module 14 is configured to establish a three-dimensional model of the target object and a three-dimensional model of the scene according to the three-dimensional data of the target object and the three-dimensional data of the scene, respectively. The coupling module 16 is for coupling a coordinate system of a three-dimensional model of the target object into a coordinate system of a three-dimensional model of the scene. The application module 18 is configured to configure a three-dimensional model of the target object in the three-dimensional model of the scene to simulate the configuration of the target object in the scene.
Similar to the first embodiment of the present application, in the second embodiment of the present application, the application module 18 includes an interference unit 182, an interaction unit 184, and a measurement unit 186. However, in the second embodiment of the present application, the application module 18 further includes a control unit 188.
In order to avoid redundancy, the same or similar parts as those of the first embodiment in the second embodiment will not be described again.
The three-dimensional data on the target object, that is, the three-dimensional data of the robot in the second embodiment of the present application, can be acquired in a similar manner to the above-described acquisition of the three-dimensional data of the home; alternatively, the user downloads himself on the official website of the purchasing robot; alternatively, the three-dimensional data of the robot is stored in the memory of the robot itself, and the three-dimensional scene simulation device 10 may transmit a request instruction to the robot so that the robot transmits the three-dimensional data to the three-dimensional scene simulation device 10. Of course, the user may also hold the mobile device including the three-dimensional camera, and take pictures or photographs of the household robot from a plurality of angles, thereby obtaining three-dimensional data of the robot.
The control unit 188 is configured to plan a travel route of the target object according to the three-dimensional model of the scene.
In this way, the user can plan the travel route of the three-dimensional model of the robot in the three-dimensional model of the home by means of the control unit 188, so as to achieve planning of the travel route of the robot in a realistic home scene.
Note that the control unit 188 may be configured to automatically plan the travel route, or may be configured to plan the travel route based on a user instruction. When the control unit 188 automatically plans the travel route, the control unit 188 determines the travel route of the robot three-dimensional model in the home three-dimensional model according to the three-dimensional model of the robot and the spatial attribute of the three-dimensional model of the home, and then combines the tasks to be completed by the robot to provide a plurality of travel routes for the user to select.
When the control unit 188 plans the travel route based on the instruction of the user, the user can move the three-dimensional model of the household robot in the three-dimensional model of the household in a similar manner to the three-dimensional model of the household in which the furniture is moved, similar to the first embodiment of the present application. After the movement is completed, the control unit 188 may send the movement route to the memory 15 for saving.
In addition, whether the control unit 188 automatically plans the travel route or plans based on the user's instructions, the user can make individual adjustments to the travel route after planning the travel route. The user may input the adjustment data through the interaction module 17, and then the control unit 188 re-plans the travel route according to the adjustment data.
The target object may also include a motion device 22 and a sensing device 24 thereon.
The movement device 22 is used for driving the target object to move.
The control unit 188 is configured to control the movement device 22 to move the target object in the scene according to the pre-planned travel route of the target object.
In this manner, the user can control the movement of the target object through the control unit 188. Specifically, the exercise device 22 may communicate with the control unit 188 via bluetooth, WI-FI (Wireless-Fidelity), or the like. The control unit 188 may send the designed travel route to the exercise device 22 in the manner described above. The movement device 22 can control the robot to move in a real home scene according to the travel route when receiving the movement instruction sent by the control unit 188.
The sensing device 24 includes, but is not limited to, a three-dimensional camera, an ultrasonic ranging sensor, a gyroscope, an infrared detector, and the like. The three-dimensional camera may be disposed on top of the robot and may be rotated to capture an image of the environment surrounding the robot. The gyroscope is used for sensing the motion state of the target object. The ultrasonic ranging sensor and the infrared detector are used for sensing spatial parameters such as the position, the distance, the size and the like of the obstacle in the advancing process so as to provide references for obstacle avoidance of a target object in the advancing process.
The actual travel situation often varies from the planned route, so the control unit 188 is also configured to control the target object to avoid an obstacle according to the motion state of the target object and the obstacle situation in front of the travel route, which are sensed by the sensing device 24.
After the target object avoids the obstacle, the control unit 188 determines whether to guide the target object back to the original planned route or select another planned route with better performance according to the sensed current position of the target object through factors such as the long distance of the reference path and the task completion.
