[0035] In the related art, after the 3D camera is assembled, it is fixed at a suitable distance from the photographed position. The 3D camera continuously photographs the photographed position and collects temperature fluctuation data of the 3D camera at the same time. It is determined whether the performance of the 3D camera is within an appropriate range based on the temperature fluctuation data.
[0036] However, when different models of 3D cameras are used for temperature drift testing, the distances between different models of 3D cameras and the shooting position are different, and the positions of different models of 3D cameras need to be manually adjusted to meet the corresponding shooting distances. Since the shooting distances obtained by manually adjusting the positions of 3D cameras have large deviations, the test accuracy will be reduced.
[0037] In view of this, the embodiment of the present disclosure provides a test fixture, which drives the 3D camera to be tested to move relative to the photographed position, so that the shooting distance meets the requirements and the deviation of the shooting distance is small, thereby improving the test accuracy. In addition, there is no need to manually adjust the shooting distance repeatedly, which can reduce labor intensity and improve test efficiency.
[0038] The test tooling provided in the embodiments of the present disclosure is described below in conjunction with the accompanying drawings.
[0039] Figure 1 is a schematic diagram of a three-dimensional structure of a test tool provided in an embodiment of the present disclosure, Figure 2 yes Figure 1 The front view of the test fixture is shown in FIG. Figure 3 yes Figure 1 Schematic diagram of a top view of the test fixture shown.
[0040] See also Figures 1 to 3 As shown, the test fixture provided by the present disclosure includes a support assembly, a first drive device, a movable part 300 and a camera mounting assembly. The support assembly is used to fix the test fixture and to support the first drive device, the movable part 300 and the camera mounting assembly. The support assembly is used to be fixed at a fixed position, for example, the support assembly is fixed on the ground, and of course, the support assembly can also be fixed at other positions.
[0041] The movable member 300 is movably connected to the support assembly, that is, the movable member 300 can move relative to the support assembly. The movable member 300 is transmission-connected to the first driving device, and the first driving device is used to drive the movable member 300 to move along the first direction X. The camera mounting assembly is fixedly mounted on the movable member 300, and the camera mounting assembly includes a first camera mounting position and a second camera mounting position, the first camera mounting position and the second camera mounting position are arranged at intervals along the first direction X, and the first camera mounting position and the second camera mounting position are arranged at intervals along the second direction Y. Among them, the first direction X is perpendicular to the second direction Y.
[0042] In the embodiment of the present disclosure, the first direction X, the second direction Y and the third direction Z are perpendicular to each other. For example, the first direction X can be defined as the gravity direction, that is, the first direction X can be the height direction of the support assembly. Of course, the first direction X can also be other directions, which will not be described here one by one.
[0043] During the use of the test fixture, after the camera to be tested is installed at the first camera installation position and / or the second camera installation position, the first driving device is controlled to drive the movable member 300 to move relative to the photographed position, so that the shooting distance between the camera to be tested and the photographed position meets the requirements, and the deviation of the shooting distance is small, thereby improving the test accuracy. In addition, there is no need to manually adjust the shooting distance repeatedly, which can reduce labor intensity and improve test efficiency.
[0044] In addition, the first camera mounting position and the second camera mounting position are used to install cameras of different models, so that the camera mounting assembly can be connected to cameras of different models at the same time, and the test tooling can perform temperature drift tests on cameras of different models at the same time, thereby improving test efficiency.
[0045] It should be noted that there is no limitation on the photographed position. For example, the photographed position may be a ground area opposite to the movable member 300 along the first direction X.
[0046] The specific structure of the support assembly is not limited here. For example, see Figures 1 to 3 As shown, the support assembly may include two support members 110 extending along the first direction X. The two support members 110 are spaced apart along the second direction Y, and the movable member 300 is slidably connected to the two support members 110 at opposite ends along the second direction Y, and the camera mounting assembly is located between the two support members 110. At this time, the support assembly and the movable member 300 may form a gantry.
[0047] For example, see Figures 1 to 3As shown, the first driving device may include two driving assemblies 210, each supporting member 110 corresponds to one driving assembly 210, and the two driving assemblies 210 are respectively connected to opposite ends of the movable member 300. By driving the movable member 300 to move along the first direction X by the two driving assemblies 210, the stability of the movement of the movable member 300 can be improved, and the deviation of the shooting distance can be further reduced.
[0048] The specific structure of the driving assembly 210 is not limited here. Exemplarily, the driving assembly 210 may include a driving motor and a transmission member, wherein the driving motor is mounted on the support member 110 and is connected to the movable member 300 through the transmission member, and the driving motor drives the movable member 300 to move along the first direction X through the transmission member.
[0049] In some possible implementations, see Figure 1 As shown, the camera mounting assembly may include a first camera mounting bracket 410 and two second camera mounting brackets 420. The first camera mounting bracket 410 has a plurality of first camera mounting positions, and each second camera mounting bracket 420 has a plurality of second camera mounting positions. Along the second direction Y, the first camera mounting bracket 410 is located between the two second camera mounting brackets 420, and the first camera mounting bracket 410 and the second camera mounting bracket 420 are respectively mounted on the movable member 300.
[0050] The first camera mounting bracket 410 has a plurality of first camera mounting positions, and the second camera mounting bracket 420 has a plurality of second camera mounting positions, so that the camera mounting assembly can install a plurality of cameras of different models at one time, thereby improving the testing efficiency.
[0051] It should be noted that in addition to including a first camera mounting bracket 410 and two second camera mounting brackets 420, in some embodiments, the camera mounting assembly may also include two first camera mounting brackets 410 and one second camera mounting bracket 420. In this case, along the second direction Y, the second camera mounting bracket 420 is located between the two first camera mounting brackets 410.
[0052] In some other embodiments, the number of the first camera mounting bracket 410 and the number of the second camera mounting bracket 420 may both be plural. In this case, the first camera mounting bracket 410 and the second camera mounting bracket 420 are arranged alternately and at intervals along the second direction Y.
[0053] In the embodiment of the present disclosure, the specific structure of the first camera mounting bracket 410 is not limited here. Figure 1 As shown, the first camera mounting bracket 410 may include two frame portions 411 , which are respectively located at opposite sides of the movable member 300 and are respectively fixedly connected to the movable member 300 .
[0054] For example, see Figure 1 As shown, the structure of the frame portion 411 may be an E-shape, but the frame portion 411 may also be other structures.
[0055] In the embodiment of the present disclosure, the specific structure of the second camera mounting bracket 420 is not limited here. Figures 1 to 3 As shown, each second camera mounting bracket 420 may include a camera mounting component 421 and a connecting component 422, wherein the first end of the connecting component 422 is connected to the movable component 300, and the second end of the connecting component 422 is connected to the camera mounting component 421, and the camera mounting component 421 has a plurality of second camera mounting positions, and the length direction of the camera mounting component 421 is parallel to the third direction Z, that is, the extension direction of the camera mounting component 421 is the third direction Z.
[0056] like Figure 1 As shown, the camera mounting member 421 has a spacing with the first camera mounting bracket 410 in the first direction X through the connecting member 422, so that the first camera mounting position and the second camera mounting position can be respectively connected to cameras of different models, so that the movable member 300 moves relative to the photographed position, enabling cameras of different models to be at corresponding working distances.
[0057] In some embodiments, see Figure 3 As shown, the width of the camera mounting member 421 in the second direction Y is smaller than the width of the first camera mounting bracket 410 in the second direction Y, so that the camera mounting member 421 and the first camera mounting bracket can be connected to cameras of different models respectively.
[0058] In some possible implementations, the connecting member 422 may be slidably connected to the movable member 300, and the connecting member 422 is used to move relative to the movable member 300 along the first direction X. At this time, the test fixture further includes a second driving device (not shown in the figure), which is transmission-connected to the connecting member 422, and the second driving device is used to drive the second camera mounting bracket 420 to move along the first direction X.
[0059] By driving the second camera mounting bracket 420 to move along the first direction X through the second driving device, the distance of the camera carried by the second camera mounting bracket 420 relative to the photographed position can be further adjusted to ensure that the cameras at different camera mounting positions are at corresponding working distances.
[0060] There is no limitation on how the movable member 300 is slidably connected to the connecting member 422. For example, the movable member 300 may include a horizontal portion extending along the second direction Y and a vertical portion extending along the first direction X, wherein both ends of the horizontal portion are respectively connected to the two supporting members 110, and the vertical portion is slidably connected to the connecting member 422.
[0061] The specific structure of the second driving device is not limited here. For example, the second driving device can be a cylinder member, the cylinder member can be fixed on the movable member 300, the output end of the cylinder member is fixedly connected to the connecting member 422, and the cylinder member is used to drive the connecting member 422 to move along the first direction X.
[0062] In some possible implementations, the test fixture may further include a shading device, and a shading device is provided between adjacent first camera mounting brackets 410 and second camera mounting brackets 420 along the second direction Y. In this way, the shading device can prevent the cameras on the first camera mounting bracket 410 and the second camera mounting bracket 420 from light scattering each other, thereby improving the accuracy of the test.
[0063] See also Figure 3 As shown, the number of the first camera mounting bracket 410 is one, the number of the second camera mounting bracket 420 is two, and therefore, the number of the shading devices is two.
[0064] Exemplarily, the shading device may include a carrier 500 (eg Figure 1 The supporting member 500 is mounted on the movable member 300, and the length direction of the supporting member 500 is parallel to the third direction Z. The shading curtain is suspended on the supporting member 500, and the length of the shading curtain in the third direction Z is greater than the length of the first camera mounting bracket 410 in the third direction Z, and greater than the length of the second camera mounting bracket 420 in the third direction Z.
[0065] The shading curtain is made of shading material to shield the cameras on the first camera mounting bracket 410 and the second camera mounting bracket 420 from light.
[0066] The specific structure of the blackout curtain is not limited here. For example, the blackout curtain can be an integrated plate structure.
[0067] The blackout curtain can be movably connected or fixedly connected to the carrier 500. For example, the blackout curtain can be slidably connected to the carrier 500, and the blackout curtain can move along the third direction Z relative to the carrier 500.
[0068] The specific structure of the bearing member 500 is not limited here. Figure 1 and Figure 3 As shown, the bearing member 500 may include two bearing rods 510, which are located on opposite sides of the movable member 300 and are respectively fixedly connected to the movable member 300, and the extension direction of each bearing rod 510 is parallel to the third direction Z. Alternatively, in some embodiments, the bearing member 500 may also be an integrated rod structure.
[0069] In some possible implementations, the test tool may also include a display 600 (eg, Figure 1 The display 600 and the industrial computer are both mounted on the support assembly, the display 600 is electrically connected to the industrial computer, and the industrial computer is used to be electrically connected to the first driving device, the second driving device and the camera to be tested mounted on the camera mounting assembly.
[0070] During the temperature drift test, the industrial computer can control the first driving device and / or the second driving device according to the shooting distance corresponding to the cameras installed at the first camera installation position and the second camera installation position, so that the movable part 300 and / or the second camera installation bracket 420 moves relative to the photographed position, ensuring that the cameras at the first camera installation position and the second camera installation position are at the corresponding shooting distance.
[0071] In addition, the industrial computer can also control the camera on the camera mounting assembly to be tested to continuously take pictures of the photographed position. At the same time, the industrial computer will collect the temperature fluctuation data of the camera, and determine whether the performance of the camera is within the appropriate range based on the temperature fluctuation data. Finally, the test results are displayed on the display 600.
