An embodiment of the present invention also provides a multi-lens camera system. As shown in FIG. 3 , the camera system includes: a plurality of mirror surfaces that are seamlessly connected with the horizontal plane at 45°, and the adjacent mirror surfaces are unfolded at a certain horizontal angle. . Multiple cameras are designed to be distributed vertically to each mirror surface so that they can receive 45° reflected light from the mirror. The camera will capture the virtual image of the scene in front reflected by the reflective mirror. According to the principle of light reflection, by designing the angle of the mirror and the placement of the camera, these cameras can all have the same virtual optical center, that is, multiple cameras are from the same optical center. Viewpoint captures images without parallax. As shown in Figure 4 and Figure 5, the virtual optical centers of the multi-lens of the multi-lens camera system can overlap in both the horizontal and vertical directions, which enables the video images formed by each sub-camera unit of the system to be seamlessly spliced to form a Overall panorama. As shown in Figure 4, the mirror surface is actually an isosceles trapezoid, which is connected to an axial horizontal motor and a connecting rod. In the horizontal direction, the adjacent fold line can be used as the axis to rotate and move, as shown in Figure 4 and Figure 5 , the camera will be fixed on an angular stage that can vertically lift rails and tilt forward and backward, allowing it to move in two dimensions. In the way of realizing the precise parallel segmentation of the field of view, the present invention adopts the way of adjusting the mirror surface to pursue a more accurate original stitched image.

As shown in Figure 6, from a geometrical optics point of view, the camera's field diaphragm is usually located at the image chip position, not the mirror surface position. Therefore, at the position of the reflecting mirror surface, the influence of stray light of adjacent reflecting surfaces can only be eliminated and the partial public field of view can be divided, but the problem of the common field of view (the overlapping of the fields of view and the inaccurate segmentation) cannot be completely solved. Therefore, a drive motor along the direction of the camera is introduced, and the lens is adjusted up and down, so that the distance between the camera and the mirror changes accordingly, so that x more accurately meets the condition of L/2tan (θ/2) and achieves accurate parallel segmentation of the field of view. Also because the mirror surface is not an accurate field diaphragm, there will be edge stray light outside the field of view entering the camera, but because there is no light energy attenuation caused by the polarization analyzer, the lens aperture can be reduced to ensure the camera's field of view. While the internal light is imaged normally, the influence of stray light outside the field of view is reduced. And at this time, because x already satisfies the condition of perfect segmentation of the field of view, the stray light reflected from the adjacent mirror surfaces in Figure 6 cannot enter the field of view of the camera, so there is no need to use polarized light.

The above method can already realize the adjustment of x=L/2tan(θ/2). When the lens performs optical zooming, θθ changes. At this time, the common optical center adjustment needs to be performed again. As shown in Figure 7 and Figure 8, it is necessary to adjust the distance x from the lens to the mirror surface and the angle α between the adjacent mirror surfaces. The mirror surface is designed as a structure in which multiple mirrors are seamlessly connected. For example, in the case of three mirror surfaces, the middle mirror surface is fixed, and the angle α between the mirrors on both sides and the middle mirror is adjusted by the drive motor. The actual physical correspondence of x-x' is shown in Figure 8, which is the distance from the mirror to the physical optical center. According to the reflection principle, this distance can be equivalent to the distance from the reflection surface to the virtual optical center. In this way, through the adjustment of x and α, in the case of zooming, that is, in the case of changing θ, an accurate common optical center optical path is still achieved, and the stitching effect of optical images is maintained. As shown in Figure 7, assuming that the lens is zoomed and adjusted, the field of view of each lens becomes θ'. To achieve a new equivalent co-optical center system, the angle α between adjacent prism surfaces needs to be adjusted. is α'=180°-θ', and when the dimension L of the mirror cannot be changed, adjust x to x'=L/2tan(θ'/2). And according to the different deployment scenarios, the camera system needs to have a certain pitch angle to meet the needs of lower-position and lower-position shooting. For the reflective system, the camera needs to have a certain rotation angle around the physical optical center and along the direction of the mirror, such as shown in Figure 9.

FIG. 10 is a schematic diagram of the control structure of a multi-lens camera system provided by an embodiment of the present invention. As shown in FIG. 10 , the optical path adjustment of the common optical center camera can be realized electrically, and a corresponding control circuit is designed. The calibrated parameters or externally input data commands are used to control and drive the axial motor by using a Microcontroller Unit (MCU), so that the structural components are in the proper position for splicing and imaging.

The optomechanical parameters that need to be adjusted for the concentric camera are:

1. The vertical distance x between the camera and the mirror, because the camera and the reflecting surface are at an angle of 45°, when the camera moves vertically, the displacement of each camera is exactly the same, and it needs to be adjusted synchronously to maintain the consistency of the splicing, so this The distance adjustment can use an axial motor to bind 3 cameras for synchronous movement.

2. The angle α of the adjacent mirror surfaces, since the symmetrical layout of the left and right mirror surfaces and the middle mirror surface is the same, it needs to be adjusted synchronously in order to maintain the consistency of the splicing, so the adjustment of this angle can use an axial motor through the connecting rod mechanical structure , push the left and right mirrors to move synchronously;

3. The pitch angle β of the lens, since each reflective mirror and the camera form a 45° reflective system, the pitch operation can be performed synchronously. The specific implementation is to use integral fixings to fix the three cameras, and install them on a high-precision On the angular displacement stage, the overall pitch of the three cameras is achieved through this mechanism.

In summary, a total of 2 electronically controlled guide rails and 1 electronically controlled angular displacement stage are required. Each time the focal length changes, the MCU needs to independently control multiple motors and adjust the corresponding parameters according to the pre-existing calibration data in the Electrically Erasable Programmable Read Only Memory (EEPROM) or the control parameters sent from the communication interface. , so that the relative positions of multiple cameras and reflecting mirrors reconstitute a common optical center system.

This invention can fully support the change and readjustment of the common optical center of the focal length of the lens, but it has high requirements on the optomechanical system, requiring the assembly of multiple mirrors to be accurate, and the adjacent mirrors should be assembled as seamlessly as possible, and the adjustment The control accuracy of the mechanism also needs to be guaranteed.

For the adjustment accuracy of the optical center, the main problem is that when the motor adjusts the mirror, because the mirror has a certain physical thickness, there may be gaps during adjustment, and the gap cannot reflect the image, so the image in some areas will be missing during image stitching. If you want to adjust the angle to 10 light (30-40 whole), if the initial angle is 30, there is no gap between adjacent mirrors, when the thickness of the mirror is 1mm, adjust the field of view to 40, the gap is 0.117mm, corresponding to 3 Meter object distance, the missing area is 4.8mm, which corresponds to 5 meters object distance, and the missing area corresponds to about 8mm. This region also further reduces the size of the missing region by special processing. If the error of the angle adjustment accuracy is 0.1%, the error of the missing area is relatively roughly 1%, that is, the error is ±0.08mm at 5 meters. From 300 field of view to 40 to 40 field of view, the change in focal length is about 1f-1.35f. The focal length f of the lens is generally of the order of mm, and the relative change of 1/100 corresponds to the focal length accuracy requirement of 0.01mm. In the present invention, the mirror is fixed on the mechanical rotating table, the camera is fixed on the electronically controlled motion guide rail, the precision of the precision optical machine/bench is high, the rotating table is better than 0.1 mm, and the guide rail is better than 0.01 mm. Therefore, in terms of relative control accuracy, a relative change of 1/100 can be fully realized.

In theory, through the design of the electronically controlled reflective mirror, the virtual optical centers of multiple cameras can be completely overlapped, so as to solve the parallax problem and achieve seamless splicing at any depth. However, due to inevitable processing and assembly errors, the optical centers of the cameras cannot be completely coincident, and the optical centers need to be dynamically adjusted at this time. The meaning of dynamic adjustment is to translate, rotate or crop the pictures of different lenses/cameras (effective area selection) through the software, so that the coordinates of the center of the field of view in the image coordinate system are dynamically changed, so as to realize the complete coincidence of the optical centers of the cameras at different positions. . As shown in Figure 11a, if the virtual optical centers of the three cameras are slightly deviated in the image coordinate system, for example, the dotted rectangle and the cross of the rectangle represent the imaging area and optical center coordinates of a lens, respectively. The optical center coordinates are compared with the normal line segment. The coordinates of the optical center of the rectangle are shifted to the upper left. By cropping the imaging area of the dashed rectangle (Fig. 11b), the optical center is dynamically adjusted to a certain value to the lower right, so that the optical center of the dashed rectangle and the normal segment rectangle are coincident. It is also possible to adjust the optical center of the dot-short-line rectangle. In terms of software processing optical center coincidence adjustment, the method of cropping will lose effective pixels, and the image needs to be zoomed. However, through the motor accuracy and adjustment method of the opto-mechanical system, it can ensure that the optical center has little offset. After calculation and actual testing, even if the cropping method is adopted, the loss of effective pixels is less than 1%, almost no scaling is required, and the impact on the image effect is very slight.
