"and/or" describes an association of associated objects, meaning that there may be three relationships, e.g., A and/or B, and that there may be A alone, while A and B are present, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one of a alone, b alone or c alone may represent a alone, b alone, c alone, a combination of a and b, a combination of a and c, b and c, or a combination of a, b and c, wherein a, b, c may be single or plural. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The terms "center," "longitudinal," "transverse," "upper," "lower," "left," "right," "front," "rear," and the like refer to an azimuth or positional relationship based on that shown in the drawings, merely to facilitate description of the present disclosure and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular azimuth, be configured and operated in a particular azimuth, and therefore should not be construed as limiting the present disclosure.
The terms "connected," "connected," and "connected" are to be construed broadly and refer, for example, to a physical connection, an electrical connection or a signal connection, for example, to a direct connection, i.e., a physical connection, or an indirect connection via at least one element therebetween, and to a communication between two elements, as long as the electrical connection is achieved, and to a signal connection, for example, via a medium other than a circuit. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art in the specific context.
In the process of measuring the parts, a user is usually required to place a single part to be measured at a measurement position, find the coordinate position where the part is placed, select a measurement program corresponding to the part to be measured through a terminal device connected with a dimension measurement device, and the dimension measurement device automatically detects the part to be measured based on the detection program. After the detection is completed, the user manually removes the part to be detected from the dimension measuring equipment, and the measurement of the part to be detected is completed. If other parts are needed to be measured, the user manually places the next part to be measured at the measuring position of the dimension measuring equipment, and repeats the steps to measure the next part to be measured.
The dimensional measuring device may be, for example, a contact space meter. The following is a brief description of the touch space meter.
The three axes of the contact type space measuring instrument are provided with an air source brake switch and a micro-motion device, so that the precise transmission of a single axis can be realized, and a high-performance data acquisition system is adopted. The touch space measuring instrument is an instrument capable of representing the measuring capabilities of geometric shape, length, circumference graduation and the like in a hexahedral space range, and is also called a three-coordinate measuring machine or a three-coordinate measuring machine bed. The contact space measuring instrument can be defined as a measuring instrument which has a detector capable of moving in three directions and can move on three guide rails perpendicular to each other, the detector transmits signals in a contact or non-contact mode, and a displacement measuring system (such as a grating ruler) of three axes calculates each point (x, y, z) of a workpiece and each function measuring instrument through a data processor or a computer. The measurement functions of the contact type space measuring instrument include dimensional accuracy, positioning accuracy, geometric accuracy, contour accuracy and the like.
Although the contact type space measuring instrument can automatically detect on the basis of the existing program, personnel are required to search and position along with the contact type space measuring instrument, and armor is required to be continuously replaced in the detection process of different parts, so that personnel resources are wasted, and the contact type space measuring instrument is idle when the personnel leave work.
Therefore, in the process of measuring the parts by the dimension measuring device, a user is required to operate the dimension measuring device, and thus, labor cost is consumed. Under unmanned condition, the size measurement equipment can not independently finish measurement work, and under the condition that personnel have a rest such as night, measurement can not be performed.
The measuring method of the parts provided by the embodiment of the disclosure can be applied to measuring equipment of the parts, and the measuring equipment of the parts is described below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a measurement device for parts according to an embodiment of the disclosure, and as shown in fig. 1, the measurement device for parts according to the embodiment includes a control module, a vision module 101 and a measurement module 102. The control module is connected with the vision module 101 and the measurement module 102, respectively. Note that, the control module is not shown in fig. 1, and the position where the control module is disposed is not limited in this disclosure. The configuration of vision module 101 and measurement module 102 shown in fig. 1 is only an example and does not constitute a limitation of the measurement apparatus of the components of the present disclosure.

Therefore, the type of the part to be measured is identified by replacing manual work through the vision module, and a corresponding measurement program is obtained according to the type of the part to be measured, so that the part to be measured is measured. All the measuring processes are automatically completed, so that the labor cost is reduced, and the efficiency of size measurement is improved. In addition, because the dimension measurement process of the parts can be automatically completed, dimension measurement can be performed by utilizing the time when personnel cannot watch at night, and the utilization rate of the part measurement equipment is improved.
The technical scheme provided by the present disclosure is described in detail below with specific embodiments.
Referring to fig. 2, fig. 2 is a flow chart of a measurement method of a component according to an embodiment of the disclosure. As shown in fig. 2, the method provided in this embodiment is performed by a measurement device of a component, which may be the measurement device of the component shown in fig. 1, or a control module, which may be a control module in the measurement device of the component shown in fig. 1. The method provided by the present embodiment may include the following steps 201-203.
Step 201, after receiving a measurement starting instruction, determining the type of at least one part to be measured in a preset area through a vision module.
The measurement starting instruction may be generated by a user trigger, for example, the measurement starting instruction may be triggered by the user pressing a measurement starting button on the measurement device of the component, or may be triggered by pressing a measurement starting control on a man-machine interaction module of the measurement device of the component, and the triggering form of the measurement starting instruction is not limited in this disclosure.
The vision module can identify the type of the part to be tested placed in the preset area.
Step 202, respectively obtaining a first measurement program corresponding to each part to be measured according to the type of each part to be measured in at least one part to be measured.
Because of the variety of the parts to be measured, there may be differences in the sizes and shapes of different types of parts to be measured, when the sizes of the parts to be measured are measured, it is generally necessary to determine a first measurement procedure for the type of the parts to be measured according to the type of the parts to be measured. The first measurement procedure generally includes an operation step when measuring the part to be measured, and taking the touch space measuring instrument as an example, the touch space measuring instrument can automatically measure the part according to the first measurement procedure to obtain a measurement result.
Step 203, based on the first measurement procedure corresponding to each part to be measured, the control measurement module measures the dimensions of each part to be measured.
The measuring module is used for measuring the size of the part to be measured. The measurement module may be, for example, a contact space meter.
According to the method for measuring the parts, after the measurement starting instruction is received, at least one type of the part to be measured in the preset area is automatically obtained through the vision module, the first measurement programs corresponding to the parts to be measured are respectively obtained according to the types of the parts to be measured, and the measurement modules are controlled to respectively measure the sizes of the parts to be measured based on the first measurement programs corresponding to the parts to be measured, so that measurement results are obtained. Therefore, the type of the part to be measured is identified by replacing manual work through the vision module, and the measurement module is triggered to measure the size of the part to be measured according to the identified type of the part to be measured, so that a measurement result is obtained. The measuring process can be automatically completed on various types of current parts and different types of future parts, so that the labor cost is reduced, the time consumption for measuring the dimension is short, and the efficiency of measuring the dimension is improved. In addition, the size measurement process of the parts can be automatically completed, so that the size measurement can be performed by utilizing the time that the personnel cannot watch at night, and the utilization rate of the measurement equipment of the parts is improved.
In some embodiments, step 201 may be implemented by the following steps 2011 and 2012.
And step 2011, acquiring part images of at least one part to be measured in a preset area through a vision module after receiving a measurement starting instruction.
Further, the vision module may include a camera. For example, the cameras may be two-dimensional cameras and three-dimensional cameras.
Wherein the part images may be one or more, the present disclosure does not limit the number of part images. The part image may be an image taken of all the parts to be measured in the predetermined area, or may be an image taken of each part to be measured in the predetermined area.
Further, the control module may send a shooting instruction to the vision module after receiving the measurement start instruction, and the vision module shoots a part image of at least one part to be measured in the preset area after receiving the shooting instruction, and sends the part image to the control module.
Step 2012, determining the type of each part to be tested in the at least one part to be tested according to the part image.
In one possible implementation, the part image may be imported into a part type classification model to obtain the type of each part to be tested.
The part type classification model is built based on a deep learning model, and a model which is finished by autonomous learning in advance, namely a model which is finished by training in advance. The part type classification model may be trained from images of multiple types of parts.
In another possible implementation manner, images of multiple types of parts may be stored in advance, and the part images may be compared with the images of the multiple types of parts stored in advance to determine the types of the parts to be tested.
According to the method for measuring the parts, after the measurement starting instruction is received, part images of at least one part to be measured in the preset area are automatically acquired through the vision module. And determining the type of at least one part to be measured in a preset area according to the part image, respectively obtaining first measurement programs respectively corresponding to the parts to be measured according to the type of the parts to be measured, and controlling the measurement module to respectively measure the sizes of the parts to be measured based on the first measurement programs respectively corresponding to the parts to be measured. Therefore, the type of the part to be measured is identified by replacing manual work through the vision module, and a corresponding measurement program is acquired according to the type of the part to be measured, so that the part to be measured is measured based on the measurement program. The size measurement process of the parts is automatically completed, the labor cost is reduced, and the efficiency of size measurement is improved. In addition, because the dimension measurement process of the parts can be automatically completed, dimension measurement can be performed by utilizing the time when personnel cannot watch at night, and the utilization rate of the part measurement equipment is improved.
In some scenarios, the measurement module needs to move to the part to be measured according to the position of the part to be measured, so as to measure the part to be measured. Therefore, the vision module can also acquire the position information of the part to be measured, so that the measurement module is controlled to accurately measure the part to be measured at the position. Specific examples are described in detail below.
In some embodiments, the following step 2013 may also be included after step 2011. Accordingly, step 203 may be implemented by the following step 2031.
Step 2013, determining first position information of each part to be tested according to the part image of at least one part to be tested.
The first position information is used for indicating the position of the part to be tested in the space. For example, the first position information may be X/Y/Z coordinate information of the part to be tested in space. For example, the coordinate system used for the coordinate information may be an X/Y/Z coordinate system established with a preset point on a preset area as an origin.
Furthermore, the coordinate positioning and searching can be carried out on the part to be detected through a hand-eye calibration method. For example, the coordinate positioning search can be performed on the part to be tested according to a 9-point method.
Step 2031, controlling the measurement module to measure the sizes of the parts to be measured based on the first measurement program of the parts to be measured and the first position information of the parts to be measured, so as to obtain measurement results corresponding to the parts to be measured.
In this embodiment, according to the part image of at least one part to be measured, the first position information of each part to be measured and the type of each part to be measured are determined, and based on the first measurement program of each part to be measured and the first position information of each part to be measured, the control measurement module performs size measurement on each part to be measured, so as to obtain the measurement result corresponding to each part to be measured. The size measurement process of the parts is automatically completed, the labor cost is reduced, and the efficiency of size measurement is improved. In addition, because the dimension measurement process of the parts can be automatically completed, dimension measurement can be performed by utilizing the time when personnel cannot watch at night, and the utilization rate of the part measurement equipment is improved.
In some embodiments, step 2011 may include steps 20111-20114, and accordingly, step 2013 may be implemented by steps 20131 and 20132 as follows.
Step 20111, starting from the starting position of the preset area, respectively acquiring sub-area images of all sub-areas of the preset area through a vision module.
The preset area is divided into a plurality of subareas, and the same type of parts to be tested can be placed in the same subarea. After receiving the measurement starting instruction each time, scanning each subarea from the starting position of the preset area through the vision module, and respectively obtaining subarea images of each subarea.
And step 20112, determining the two-dimensional position information of each part to be tested in the preset area according to the subarea image of each subarea of the preset area.
The two-dimensional position information is used for indicating the position of the part to be tested in the preset area. For example, the two-dimensional position information may be X/Y coordinate information of the part to be measured in a preset area. For example, the coordinate system used for the coordinate information may be an X/Y coordinate system established with a preset point on a preset area as an origin.
And determining the parts to be tested and the two-dimensional position information of the parts to be tested, which are placed in each subarea, according to the subarea images of each subarea.
And step 20113, determining the measuring sequence of each part to be measured according to the second position information of each part to be measured.
In general, the measurement order may be determined based on the distance of the second position information from the origin of the coordinate system, i.e. the closer to the original coordinate system the sub-region is, the earlier the measurement order is. For the parts to be measured in each sub-area, the measurement can also be performed according to a custom measurement sequence.
And step 20114, acquiring part images of the parts to be measured through the vision module according to the measuring sequence of the parts to be measured and the two-dimensional position information of the parts to be measured in the preset area.
And 20131, determining coordinate information of feature points of each part to be tested according to the part image of the at least one part to be tested.
The feature points refer to points capable of determining the positions and the postures of the parts to be tested. Typically, the feature points of a part to be tested may be one or more.
And 20132, taking the coordinate information of the feature points of the part to be tested as the first position information of the part to be tested.
And acquiring part images of the parts to be measured through the vision module according to the measuring sequence of the parts to be measured and the two-dimensional position information of the parts to be measured in the preset area. It will be appreciated that the part image is more accurate relative to the sub-region image and, correspondingly, the first positional information is more accurate relative to the second positional information.
In this embodiment, from the starting position of the preset area, the sub-area images of the sub-areas of the preset area are respectively obtained through the vision module. And determining the two-dimensional position information of each part to be detected in the preset area according to the subarea image of each subarea of the preset area, thereby realizing the coarse positioning process. Determining the sequence of measuring each part to be measured according to the second position information of each part to be measured, and acquiring part images of each part to be measured through a vision module according to the sequence of measuring each part to be measured and the two-dimensional position information of each part to be measured in a preset area, so as to obtain the type and the first position information of each part to be measured, and realizing the precise positioning process. Through the rough positioning and the fine positioning processes, the positions of the parts to be measured in the space are accurately identified, the first measurement programs corresponding to the parts to be measured are obtained according to the types of the parts to be measured, and the measurement modules are controlled to measure the sizes of the parts to be measured based on the first measurement programs corresponding to the parts to be measured. Therefore, the type of the part to be measured is identified by replacing manual work through the vision module, and a corresponding measurement program is acquired according to the type of the part to be measured, so that the part to be measured is measured based on the measurement program. The size measurement process of the parts is automatically completed, the labor cost is reduced, and the efficiency of size measurement is improved. In addition, because the dimension measurement process of the parts can be automatically completed, dimension measurement can be performed by utilizing the time when personnel cannot watch at night, and the utilization rate of the part measurement equipment is improved.
In some embodiments, the vision module may be moved, and the measurement module may also be moved, where both of them need to be moved above and around the component to be measured, so, to ensure safety, that is, to ensure that the two cannot collide with each other, safety measures may be added in the working process of the measurement device of the component, so as to ensure safety of the measurement device of the component. Specific examples are described in detail below.
Further, step 203 may comprise step 203a and step 203b on the basis of any of the above embodiments.
Step 203a, after determining that the vision module is at the safe position, controlling the measurement module to measure the sizes of the parts to be measured based on the first measurement programs corresponding to the parts to be measured, respectively, so as to obtain measurement results corresponding to the parts to be measured.
The safe position refers to the position and the posture of the vision module, and the position and the posture are in a position and the posture which do not cause injury to personnel and equipment. Since the measuring module is usually in an initial position, the measuring head of the measuring module usually moves around the part to be measured when the measuring procedure is performed, so the vision module needs to ensure that the vision module cannot collide with the measuring head of the measuring module, i.e. is in a safe position.
Further, it may be determined whether the vision module is in a safe position by the light curtain infrared module.
In this embodiment, after determining that the vision module is at the safe position, the control module controls the measurement module to measure the sizes of the parts to be measured respectively based on the first measurement programs corresponding to the parts to be measured respectively, so as to obtain measurement results corresponding to the parts to be measured.
Further, prior to step 203a, the control module may place the vision module in a safe position by sending an end-of-job instruction to the vision module. The vision module may also be preset to be automatically in a safe position after the shooting of the part image is completed.
Further, in one possible implementation, the vision module may return to the safe position after acquiring the part images of all the parts under test, and the vision module sends the part images to the control module. The control module determines the type and the first position information of each part to be measured, acquires a corresponding first measurement program according to the type of each part to be measured, and sends the first measurement program and the first position information of each part to be measured to the measurement module. The measuring module is used for measuring the sizes of the parts to be measured based on a first measuring program and first position information of the parts to be measured, and the measuring module returns to a safe position of the measuring module after measuring.
In another possible implementation, the vision module may return to the secure position after each acquisition of a part image of one part under test, and the vision module sends the part image to the control module. The control module determines the type and the first position information of the part to be measured, acquires a corresponding first measurement program according to the type of the part to be measured, and sends the first measurement program and the first position information of the part to be measured to the measurement module. The measurement module performs size measurement on the part to be measured based on a first measurement program and first position information of the part to be measured, returns to a safe position of the measurement module after the measurement of the part to be measured is completed, and sends a measurement completion notification to the control module. The control module controls the vision module to continuously acquire the part image of the next part to be measured, and returns to the execution of the 'return to the safe position' until the measurement module measures all the parts to be measured.
In some embodiments, step 203 is followed by step 204 as follows.
And 204, sending measurement results corresponding to the parts to be measured to the terminal equipment.
The measurement results corresponding to the parts to be measured comprise measurement result data corresponding to the parts to be measured.
The measurement results corresponding to the parts to be measured further comprise first position information of the parts to be measured and/or measurement time of the parts to be measured.
In general, the position of the part to be measured in the area to be measured is not changed before and after the measurement is performed on the part to be measured, so that the measurement result can carry the first position information of the part to be measured, and the terminal device can determine that the measurement result is the measurement result of the part to be measured corresponding to the first position information. In addition, when the parts to be measured are measured, the measurement sequence of the parts to be measured can be determined according to the relative position relationship of the parts to be measured in the preset area, so that the parts to be measured corresponding to the measurement result can be determined according to the measurement time of the parts to be measured.
In this embodiment, after the measurement is finished, the measurement results corresponding to the parts to be measured are sent to the terminal device, so that the measurement results are automatically derived, and the efficiency is improved.
In some embodiments, the method provided in this embodiment may further include the following step 205.
