[0042] Please refer to Figure 1 And Figure 2 As shown in the figure, the embodiment discloses a multi-camera group test equipment (for easy display, Figure 1 The front plate, side plate and top plate of the upper box body 610 are hidden), for testing a multi-camera group 900 with multiple cameras and at least two cameras whose fields of view do not coincide, the multi-camera group test equipment includes a multi-camera group clamp 100 and at least one test group 200, the multi-camera group clamp 100 is used for clamping the multi-camera group 900;The test group 200 includes a plurality of test cards 210, and the test cards 210 are arranged around the multi-camera group clamp 100 and correspond one-to-one to the cameras in the multi-camera group 900 whose fields of view do not coincide.

[0043] It should be noted that the camera test equipment in the related art usually tests the performance parameters of a single camera by using a test card, and when it is applied to the multi-camera group 900, there is a problem of low test efficiency caused by testing the cameras one by one.

[0044] According to the multi-camera group test equipment of the utility model embodiment, the worker clamps and fixes the multi-camera group 900 on the multi-camera group clamp 100, the corresponding test card 210 is arranged in the multi-camera group test equipment for the multiple cameras whose fields of view do not coincide, and the multiple cameras can complete the test of a single item (such as white map test) synchronously, thereby effectively improving the test efficiency of the multi-camera group 900.

[0045] It should be noted that in order to ensure that each camera of the multi-camera group 900 can be tested simultaneously, the field of view of each camera of the multi-camera group 900 to which the multi-camera group test equipment in the application is applied does not coincide, so as to ensure the test accuracy;Of course, it can be understood that when there are some cameras in the multi-camera group 900 whose fields of view coincide, the cameras whose fields of view coincide can be tested separately, and the other cameras whose fields of view do not coincide can be tested simultaneously, thereby effectively improving the test efficiency of the multi-camera group test equipment.

[0046] In the embodiment, the multi-camera group test equipment further includes an upper box body 610 and a lower base 620, and the upper box body 610 and the lower base 620 enclose a test space, the test card 210 and the multi-camera group clamp 100 are placed in the test space, and a sealed dark environment required for lens test is provided.

[0047] In this embodiment, the lower base 620 can be placed inside the multi-camera group testing device. The electrical control assembly can provide power supply for the electrical appliances in the multi-camera group testing device, and can also provide electrical connection for different components to realize data communication or control action (such as the induction switch 130 and the indicator in the following).

[0048] In one embodiment, as shown in Figure 1 、 Figure 2 and Figure 3 , the test group 200 includes a first test group 220, and the test card 210 of the first test group 220 is a white chart test card 221. The white chart test card 221 is used to evaluate the image performance of the camera under a white background, including brightness, contrast, color restoration, and image sharpness, etc. Through this test, it can be ensured that the device can provide clear and accurate image output under various lighting conditions.

[0049] In this embodiment, as shown in Figure 3 , the multi-camera group testing device is also provided with a light-emitting plate 630, which is located below the white chart test card 221 to provide stable light for the camera of the multi-camera group 900 to shoot the pattern on the surface of the white chart test card 221.

[0050] In one embodiment, the test group 200 includes a second test group 230, and the test card 210 of the second test group 230 is an SFR (spatial frequency response chart) test card 231. By shooting the picture of the SFR test card 231 with the camera, the response of the camera to the spatial frequency is measured to evaluate the image sharpness, contrast, and modulation transfer function (MTF), etc. These indicators are crucial to ensure that the camera can provide high-quality image output under various lighting and imaging conditions.

[0051] Of course, in other embodiments, the test card 210 can also be a standard resolution test card for testing the fineness of the image captured by the camera.

[0052] According to some embodiments of the present application, as shown in Figure 1 、 Figure 2 and Figure 3 , in the case where the test group 200 includes the first test group 220 and the second test group 230, the multi-camera group testing device further includes a fixing frame 300, and the fixing frame 300 is provided with a first detection station and a second detection station; the first detection station is a station for the white chart test card 221 to be detected by the multi-camera group 900, and the second detection station is a station for the SFR test card 231 to be detected by the multi-camera group 900; the multi-camera group clamp 100 and the fixing frame 300 are connected through a first movable assembly 400, and the first movable assembly 400 is used to drive the multi-camera group clamp 100 to switch between the first detection station and the second detection station.

[0053] In the embodiment, after the staff places the multi-camera group 900 in the multi-camera group clamp 100, the multi-camera group testing device drives the multi-camera group clamp 100 to move relative to the fixed frame 300 through the first movable assembly 400, so that the fixed multi-camera group 900 moves to the first detection station, and the white chart test is performed by shooting the white chart test card 221 by the camera in the first detection station. After the white chart test is completed, the multi-camera group 900 is driven by the first movable assembly 400 to move from the first detection station to the second detection station, and the spatial frequency response chart test is completed by shooting the SFR test card 231 by the camera in the second detection station.

[0054] By setting different stations for different test items (such as white chart test or spatial frequency response chart test) in the multi-camera group testing device, the adaptability of the multi-camera group testing device to different test item requirements is improved, and the switching process of the detection station is automatically completed by the first movable assembly 400, without the need for staff to participate in adjustment, reducing the labor and time cost, and effectively improving the test efficiency of the multi-camera group testing device.

[0055] In the embodiment, as shown in Figure 2 the center position of the area surrounded by the three white chart test cards 221 is the first detection station, and the center position of the area surrounded by the three SFR test cards 231 is the second detection station. Of course, based on the camera arrangement position of the multi-camera group 900, the positions of the test card 210 and the detection station (referring to the first detection station and the second detection station) can be adaptively adjusted.

[0056] According to some embodiments of the present application, as shown in Figures 1 to 4 the fixed frame 300 includes a first fixed frame 310 and a second fixed frame 320 arranged in layers, the first fixed frame 310 is located above the second fixed frame 320, the test card 210 is installed on the first fixed frame 310, and the first movable assembly 400 is installed on the second fixed frame 320; the first fixed frame 310 is provided with a avoiding space 311 corresponding to the first detection station or the second detection station, and the avoiding space 311 is used for the multi-camera group clamp 100 to pass through; the first movable assembly 400 includes a vertical moving part 410 and a horizontal moving part 420, the vertical moving part 410 connects the multi-camera group clamp 100 and the horizontal moving part 420, and the vertical moving part 410 is used to drive the multi-camera group clamp 100 to move vertically; the horizontal moving part 420 connects the second fixed frame 320 and the vertical moving part 410, and the horizontal moving part 420 is used to drive the multi-camera group clamp 100 and the vertical moving part 410 to move horizontally as a whole.

[0057] Specifically, the multi-camera group 900 and the vertical moving part 410 as a whole are horizontally moved to the lower side of the first detection station or the second detection station under the driving of the horizontal moving part 420, and then the multi-camera group clamp 100 is lifted by the vertical moving part 410, so that the multi-camera group 900 in the multi-camera group clamp 100 can pass through the avoiding space 311 and enter the first detection station or the second detection station corresponding to the test card 210.

[0058] Since the first moving assembly and the multi-camera group clamp 100 as a whole are located between the first fixed frame 310 and the second fixed frame 320, the multi-camera group clamp 100 is effectively prevented from interfering with the fixed frame 300 and the test card 210 installed on the fixed frame 300 during movement, and the first detection station and the second detection station are always fixed, only the multi-camera group clamp 100 and the first movable assembly 400 move during detection, the position of the test card 210 is prevented from moving, the same variable is effectively controlled in each test process, the test accuracy is ensured, and the test efficiency is improved.

[0059] In the embodiment, the horizontal moving part 420 and the vertical moving part 410 both adopt a sliding table module to cooperate with a servo motor to realize accurate control of displacement; in other embodiments, a lead screw module, an air cylinder or the like can be adopted, and the multi-camera group clamp 100 can be moved.

[0060] According to some embodiments of the present application, in combination with Figure 4 The first movable assembly 400 further includes a rotating part 430, the rotating part 430 connects the multi-camera group clamp 100 and the vertical moving part 410, and the rotating part 430 is used to drive the multi-camera group clamp 100 to rotate relative to the vertical moving part 410. After the multi-camera group clamp 100 reaches the first detection station or the second detection station, the vertical moving part 410 and the horizontal moving part 420 stop moving, the multi-camera group clamp 100 is fixed relative to the test card 210, and the rotating part 430 drives the multi-camera group clamp 100 to rotate relative to the vertical moving part 410, that is, drives the multi-camera group 900 on the multi-camera group clamp 100 to rotate relative to the test card 210.

[0061] By rotating the multi-camera group 900 through the rotating part 430, it is ensured that the camera of the multi-camera group 900 can accurately align with the center position of the test card 210, and errors in the clamping or movement process of the multi-camera group 900 are avoided, so that the camera of the multi-camera group 900 cannot accurately align with the test card 210, and the accuracy of the test result is affected.

[0062] In the embodiment, the rotating part 430 can accurately drive the multi-camera group clamp 100 to rotate through a servo motor.

[0063] According to some embodiments of the present application, in combination with Figure 1 andFigure 2 As shown, the number of white chart test cards 221 and SFR test cards 231 is three, and the three white chart test cards 221 and the three SFR test cards 231 are arranged around the multi-camera group clamp 100, and in the vertical direction, the plane enclosed by the three white chart test cards 221 at least partially overlaps the plane enclosed by the SFR test cards 231.

[0064] As shown, the number of white chart test cards 221 and SFR test cards 231 is three, and the three white chart test cards 221 and the three SFR test cards 231 are arranged around the multi-camera group clamp 100, and in the vertical direction, the plane enclosed by the three white chart test cards 221 at least partially overlaps the plane enclosed by the SFR test cards 231. Figure 2 The vertical direction is the vertical paper direction, and at this time, the center points of the three SFR test cards 231 enclose a large triangular region, the three white chart test cards 221 enclose a small triangular region, and the small triangular region at least partially overlaps the large triangular region, and the generation of the overlapping region effectively compresses the space volume in the front-rear direction on the spatial arrangement of the internal components of the multi-camera group test device, effectively reducing the overall volume of the multi-camera group test device.

[0065] In this embodiment, since the SFR test cards 231 and the white chart test cards 221 are at the same horizontal height, in order to avoid interference of the white chart test cards 221 on the testing process of the SFR test cards 231, the respective enclosed surfaces of the two can only partially overlap; it can be understood that by arranging the SFR test cards 231 and the white chart test cards 221 at different horizontal heights, since the white chart test cards 221 no longer block the testing process of the SFR test cards 231, the occupied area of the multi-camera group test device in the horizontal direction can be further compressed.

[0066] According to some embodiments of the present application, in combination with Figure 3 As shown, the first test group 220 further includes an LED (light-emitting diode) test assembly 222, and the LED test assembly 222 is arranged above the multi-camera group clamp 100, and the detection field of view of the LED test assembly 222 faces the multi-camera group clamp 100. The LED test assembly 222 is arranged to detect whether the LED lamp at the top of the multi-camera group 900 is working normally.

[0067] It should be noted that for the multi-camera group 900 with an LED lamp, the working state of the LED lamp can intuitively reflect the working state of the multi-camera group 900 (for example, the LED lamp is on when the multi-camera group 900 is turned on).

[0068] In this embodiment, the LED test assembly 222 can include a camera for photographing the running condition of the LED lamp at the top of the multi-camera group 900 under the working state of the multi-camera group 900. Of course, it can also be other components that can detect whether the LED lamp is working normally, such as a photosensitive switch.

[0069] According to some embodiments of the present application, in combination with Figure 3As shown, the LED test assembly 222 is movably connected with the fixing frame 300 through a second movable assembly 500, and the second movable assembly 500 is used to drive the LED test assembly 222 to move relative to the white map test card 221.

[0070] In the embodiment, when the multi-camera group 900 is located at the first detection station, that is, the multi-camera group 900 is fixed relative to the white map test card 221, the second movable assembly 500 drives the LED test assembly 222 to move to adjust the distance between the detection field of view of the LED test assembly 222 and the LED lamp of the multi-camera group 900, effectively adapt to the multi-camera group 900 with different LED lamp positions, and improve the adaptation performance of the multi-camera group test equipment.

[0071] In the embodiment, the second movable assembly 500 adopts a sliding table module to cooperate with a servo motor to realize accurate control of displacement; in other embodiments, a lead screw module, an air cylinder or the like can be adopted, and the LED test assembly 222 can be moved.

[0072] According to some embodiments of the utility model, in combination Figure 5 As shown, the multi-camera group clamp 100 comprises a support frame 110 and a pressing plate 120, the support frame 110 is provided with a fixing groove 111 for placing the multi-camera group 900; the first end of the pressing plate 120 is pivotally connected to the support frame 110, and the second end is detachably connected to the support frame 110, and the first end and the second end are respectively located on both sides of the slot opening of the fixing groove 111; the pressing plate 120 is adapted to switch between a loosened state and a pressed state, in the loosened state, the multi-camera group 900 is adapted to pass between the pressing plate 120 and the support frame 110; in the pressed state, the pressing plate 120 and the support frame 110 are closed to clamp and fix the multi-camera group 900.

[0073] In the embodiment, when the staff has a demand for fixing the multi-camera group 900, the staff first moves the second end of the pressing plate 120, the pressing plate 120 rotates around the first end, the second end gradually moves away from the support frame 110, the pressing plate 120 is in the loosened state, so that on the cross section along the insertion direction shown in the figure, the cross-sectional area enclosed by the pressing plate 120 and the fixing groove 111 is greater than the cross-sectional area of the multi-camera group 900, so that the multi-camera group 900 can be freely inserted; after the multi-camera group 900 is inserted into the fixing groove 111, the staff moves the second end of the pressing plate 120 towards the support frame 110, the pressing plate 120 gradually approaches the surface of the multi-camera group 900, until the second end of the pressing plate 120 is fixed with the support frame 110, at this time, the pressing plate 120 is in the pressed state, and the inner side wall of the pressing plate 120 and the groove wall of the fixing groove 111 clamp and fix the multi-camera group 900.

[0074] In the embodiment, the multi-camera group 900 is cylindrical, the fixed groove 111 is semi-cylindrical, and the pressing plate 120 is semi-circular, of course, the shape of the fixed groove 111 and the pressing plate 120 can be adjusted adaptively based on the shape of the multi-camera group 900, and the multi-camera group 900 can be stably fixed on the multi-camera group clamp 100.
