[0049] At present, after the 3D camera is assembled and shipped, it will be inspected to detect the difference between the actual performance and the ideal performance of the 3D camera to ensure that the performance of the 3D camera meets the requirements. Specifically, the 3D camera is fixed at a certain distance from the calibration plate, and then the camera shoots the calibration plate. Based on the data collected by the 3D camera, the difference between the actual performance and the ideal performance of the 3D camera can be determined.

[0050] Since different models of 3D cameras have different distances from the calibration plate, it is necessary to manually adjust the position of different models of 3D cameras to ensure that the distance of the 3D camera relative to the calibration plate meets the requirements. However, the process of manually adjusting the position of the 3D camera is cumbersome, resulting in increased detection time and low detection efficiency.

[0051] In view of this, the embodiment of the present disclosure provides an inspection tool, which can automatically adjust the distance between the camera and the calibration plate according to the shooting distance corresponding to the different models of cameras when conducting factory inspection on cameras of different models, which can not only reduce the deviation of the camera shooting distance, but also simplify the process of adjusting the camera position, reduce the inspection time, and improve the inspection efficiency. In addition, it can also reduce the difficulty of connecting different models of cameras to the inspection tool, thereby reducing the time of camera installation and helping to improve the installation efficiency of the camera.

[0052] The inspection tooling provided in the embodiments of the present disclosure is described below in conjunction with the accompanying drawings.

[0053] Figure 1 is a schematic diagram of a three-dimensional structure of an inspection tool provided in an embodiment of the present disclosure, Figure 2 for Figure 1 The camera mounting assembly of the inspection tool shown is a three-dimensional structural schematic diagram at a first viewing angle, Figure 3 for Figure 2 A top view of the camera mounting assembly is shown, Figure 4 for Figure 3 Schematic diagram of the cross section in the AA direction, Figure 5 for Figure 1 A cross-sectional schematic diagram of the cooperation between the camera mounting assembly and the first base assembly of the inspection tooling shown.

[0054] See also Figure 1 and Figure 5 As shown, the inspection tooling of the embodiment of the present disclosure includes a calibration plate mounting member 100, a camera mounting assembly 200, a first driving device 300 and a first base assembly 400. The first base assembly 400 is used to carry the camera mounting assembly 200 and the first driving device 300, and the camera mounting assembly 200, the first driving device 300 and the first base assembly 400 are arranged on the same side of the calibration plate mounting member 100. The calibration plate mounting member 100 is used to be detachably connected to the calibration plate, so that the calibration plate mounting member 100 can be connected to calibration plates (not shown in the figure) corresponding to different models.

[0055] The first driving device 300 is in transmission connection with the first movable member 210, and is used to drive the first movable member 210 to move relative to the calibration plate mounting member 100 along the first direction X, so that the camera mounted on the camera mounting assembly 200 can move relative to the calibration plate. The first direction X can be understood as the projection direction of the laser emitted by the camera.

[0056] Continue to see Figures 2 to 4As shown, the camera mounting assembly 200 includes a first movable member 210, a second movable member 220 and a driving member 230. The first movable member 210 is movably connected to the first base assembly 400, so that the first movable member 210 can move relative to the first base assembly 400. The second movable member 220 is movably connected to the first movable member 210, and the driving member 230 is used to drive the second movable member 220 to move relative to the first movable member 210 to change the size of the clamping space 700 formed by the first movable member 210 and the second movable member 220, and the clamping space 700 is used to fix the camera to be inspected.

[0057] During the factory inspection of the camera, a part of the camera is placed inside the clamping space 700, and the calibration plate is placed on the calibration plate mounting part 100. The calibration plate is set toward the camera, and the camera takes continuous photos of the calibration plate. Based on the image data captured by the camera, it can be determined whether the performance of the camera meets the requirements.

[0058] In view of the fact that the inspection tooling can drive the second movable part 220 to move relative to the first movable part 210 through the driving part 230, so that the size of the clamping space 700 changes, the camera mounting assembly 200 can install cameras of different specifications, that is, the camera mounting assembly 200 can install cameras of different models, thereby realizing factory inspection of cameras of different models, and improving the application scope of the inspection tooling.

[0059] In addition, the first driving device 300 can be controlled to drive the first movable member 210 to move along the first direction X according to the working distance corresponding to different models of cameras, so that the distance between the camera and the calibration plate is a preset distance, which can not only reduce the deviation of the camera shooting distance, but also simplify the process of adjusting the camera position, reduce the detection time, and improve the detection efficiency.

[0060] There is no limitation on how the first movable member 210 and the second movable member 220 are movably connected. For example, as shown in the figure, the second movable member 220 is movably connected to the first movable member 210 through the driving member 230, so that the number of parts of the inspection tool can be reduced. Of course, the second movable member 220 may also be movably connected to the first movable member 210 without the driving member 230. In this case, the second movable member 220 may be movably connected to the first movable member 210 through other parts, or the second movable member 220 may be slidably connected to the first movable member 210.

[0061] The specific structure of the driving member 230 is not limited here. Figure 4As shown, the driving member 230 can be a cylinder, which is fixedly mounted on the first movable member 210. At this time, the second movable member 220 is fixedly mounted on the output shaft of the cylinder. The cylinder can drive the second movable member 220 to move linearly along the first direction X relative to the first movable member 210 to change the size of the clamping space 700.

[0062] The specific structure of the first movable member 210 is not limited here. Figures 2 to 4 As shown, the first movable member 210 may include a moving member 211, a shell member 212 and a fixed member 213, the first end of the moving member 211 is movably connected to the first base assembly 400, the shell member 212 is fixedly connected to the second end of the moving member 211, the shell member 212 includes a mounting opening 2121, the mounting opening 2121 communicates the inside and the outside of the shell member 212, the fixed member 213, the second movable member 220 and the driving member 230 are all arranged inside the shell member 212, the fixed member 213 and the driving member 230 are fixedly connected to the shell member 212 respectively, and the fixed member 213 and the second movable member 220 form a clamping space 700. In this way, the second movable member 220 and the driving member 230 can be hidden, thereby improving the integration of the camera mounting assembly 200.

[0063] During the process of installing the camera, a part of the camera is inserted into the interior of the clamping space 700 through the installation opening 2121, and then the driving member 230 drives the second movable member 220 to move relative to the fixing member 213, so that the clamping space 700 becomes smaller, until the fixing member 213 and the second movable member 220 clamp the camera, thereby fixing the camera.

[0064] Exemplarily, the fixing member 213 and the shell member 212 are split structures, but in some embodiments, the shell member 212 and the fixing member 213 may also be an integrated structure.

[0065] In some possible implementations, the calibration plate mounting member 100 may include a positioning portion, which is used to cooperate with a matching portion on the calibration plate to position the calibration plate mounting member 100 and the calibration plate relative to each other. In this way, the calibration plate mounting member 100 can be connected to calibration plates corresponding to cameras of different models to ensure that the positional relationship between the calibration plate and the camera meets the requirements.

[0066] Figure 6 for Figure 1 Schematic diagram of the structure of the calibration plate mounting parts of the inspection tooling shown.

[0067] One of the positioning portion and the matching portion is a positioning hole 110 (eg Figure 6As shown in the figure), the other is a positioning protrusion (not shown in the figure) for inserting into the interior of the positioning hole 110. The positioning hole 110 and the positioning protrusion cooperate with each other to locate the relative positions of the calibration plate mounting member 100 and the calibration plate.

[0068] For example, the positioning portion may be a positioning hole 110 (eg, Figure 6 As shown), correspondingly, the matching portion is a positioning protrusion. Of course, in some embodiments, the positioning portion can also be a positioning protrusion, in which case the matching portion is a positioning hole 110.

[0069] Exemplarily, the calibration plate mounting member 100 may include a plurality of positioning holes 110, such as Figure 6 As shown, the number of the positioning holes 110 is two, and of course, the number of the positioning holes 110 may be more than two. In this case, the calibration plate includes a plurality of positioning protrusions, and each positioning hole 110 corresponds to a positioning protrusion and is used for the corresponding positioning protrusion to be inserted. In this way, the positioning accuracy of the calibration plate and the calibration plate mounting member 100 can be improved by cooperating with the plurality of positioning holes 110 and the plurality of positioning protrusions.

[0070] It should be noted that the number of the positioning hole 110 may also be one, and in this case, the number of the positioning protrusion is one.

[0071] There is no limitation on the specific structure of the positioning hole 110. For example, the positioning hole 110 may be a circular hole. Of course, the positioning hole 110 may also be other structures, such as a rectangular hole.

[0072] The specific structure of the positioning protrusion is not limited here. For example, the positioning protrusion can be a cylindrical structure. Of course, the positioning protrusion can also have other structures.

[0073] In some possible implementations, the calibration plate mounting member 100 can be used to be magnetically connected to the calibration plate, and at least one of the calibration plate mounting member 100 and the calibration plate includes a magnetic member. In this way, the calibration plate mounting member 100 is connected to the calibration plate by magnetic connection, which can increase the connection or separation speed of the calibration plate and the calibration plate mounting member 100, thereby improving the efficiency of the inspection tool for inspecting cameras of different models.

[0074] It should be noted that in addition to the magnetic connection, the calibration plate and the calibration plate mounting member 100 can also be quickly connected or disassembled by other means. For example, the calibration plate can also be connected to the calibration plate mounting member 100 by snap-fitting.

[0075] There is no specific limitation on how to achieve magnetic connection between the calibration plate and the calibration plate mounting member 100. For example, the calibration plate mounting member 100 may include a first magnetic member 120 (eg, Figure 6As shown in the figure, the calibration plate includes a second magnetic member (not shown in the figure), and the first magnetic member 120 is magnetically connected to the second magnetic member. With the cooperation of the first magnetic member 120 and the second magnetic member, the calibration plate and the calibration plate mounting member 100 can be quickly connected or quickly disassembled, thereby increasing the speed of replacing the calibration plate, thereby shortening the time of inspecting the camera, and thus improving the inspection efficiency.

[0076] There is no limitation on the specific structure of the first magnetic member 120. For example, the first magnetic member 120 may be a magnet.

[0077] The specific structure of the second magnetic member is not limited here. For example, the second magnetic member can be a magnet.

[0078] It should be noted that, in addition to both having magnetic components, in some possible implementations, one of the calibration plate and the calibration plate mounting component 100 may also include a third magnetic component, and the other may also be magnetically connected to the third magnetic component. In this way, a magnetic connection between the calibration plate and the calibration plate mounting component 100 may also be achieved.

[0079] Exemplarily, the calibration plate mounting member 100 may include a third magnetic member, and in this case, the calibration plate can be magnetically connected to the third magnetic member, so that the calibration plate mounting member 100 is magnetically connected to the calibration plate. Of course, the calibration plate may also include a third magnetic member, and the calibration plate mounting member 100 is magnetically connected to the calibration plate.

[0080] The specific structure of the third magnetic member is not limited here. Exemplarily, the third magnetic member can be a magnet.

[0081] In the embodiment of the present disclosure, the specific structure of the first driving device 300 is not limited here. Figure 5 As shown, the first driving device 300 may include a first power member 310 and a first rack member 320. The first rack member 320 is fixedly mounted on the first base assembly 400, and the extension direction of the first rack member 320 is parallel to the first direction X. The first power member 310 is fixedly mounted on the first movable member 210 and is in transmission connection with the first rack member 320. In this way, the first driving device 300 can drive the first movable member 210 to move along the first direction X.

[0082] For example, see Figure 5As shown, the first power member 310 may include a first drive motor 311 and a first gear 312. The first drive motor 311 is fixedly mounted on the first movable member 210. The first gear 312 is sleeved on the motor shaft of the first drive motor 311 and is fixedly connected to the first drive motor 311. The first gear 312 is meshed with the first gear condition 320. The first drive motor 311 is transmission-connected to the first gear condition 320 via the first gear 312.

[0083] During the operation of the first driving device 300, the first driving motor 311 drives the first gear 312 to rotate, and the first gear 312 meshes with the first rack member 320 and, under the action of the first rack member 320, drives the first driving motor 311 to move along the first direction X, thereby moving the first movable member 210 along the first direction X.

[0084] In some possible implementations, see Figure 5 As shown, the first movable member 210 may further include a first cavity 214 and a first opening 215, wherein the first opening 215 communicates the inside and the outside of the first cavity 214. The second movable member 220 is disposed outside the first cavity 214, and at least a portion of the first power member 310 is disposed inside the first cavity 214, and the first power member 310 is transmission-connected to the first gear member 320 through the first opening 215. By disposing at least a portion of the first power member 310 inside the first cavity 214, the first power member 310 can be hidden, and the compactness of the first power member 310 and the camera mounting assembly 200 can be improved.

[0085] The first movable member 210 includes a movable member 211 , which is movably connected to the first base assembly 400 . At this time, the movable member 211 has a first cavity 214 and a first opening 215 , so that at least a part of the first movable member is disposed inside the movable member 211 .

[0086] Exemplarily, a portion of the first power member 310 is disposed inside the first cavity 214 , and another portion is disposed inside the first opening 215 . Of course, the first power member 310 may also be disposed inside the first cavity 214 .

[0087] Specifically, the first power member 310 includes a first driving motor 311 and a first gear 312. Figure 5 As shown, a portion of the first driving motor 311 is disposed inside the first cavity 214 , and another portion of the first driving motor 311 and the first gear 312 are disposed outside the first cavity 214 through the first opening 215 .

[0088] In the embodiment of the present disclosure, the specific structure of the first base assembly 400 is not limited here. Figure 5As shown, the first base assembly 400 may include a first support seat 410 and a first elastic shielding member 420 extending along the first direction X. The first support seat 410 is slidably connected to the first movable member 210, and the first support seat 410 includes a first accommodating space. The first elastic shielding member 420 and the first rack member 320 are both arranged inside the first accommodating space, and the first elastic shielding member 420 is located between the first movable member 210 and the first rack member 320. The first elastic shielding member 420 includes a third opening, and the first rack member 320 is transmission-connected to the first power member 310 through the third opening.

[0089] By shielding the first rack member 320 with the first elastic shielding member 420, dust and other foreign matter can be prevented from accumulating on the first rack member 320, thereby affecting the effect of the transmission connection between the first rack member 320 and the first power member 310. In addition, the first rack member 320 is arranged inside the first accommodation space, so that the first rack member 320 can be hidden.

[0090] Figure 7 yes Figure 1 A cross-sectional schematic diagram of the cooperation between the second base assembly of the inspection tooling shown and the calibration plate mounting piece.

[0091] In some possible implementations, see Figure 1 and Figure 7 As shown, the inspection tool may further include a second base assembly 500 and a second driving device 600. The calibration plate mounting member 100 is movably connected to the second base assembly 500, and the second driving device 600 is used to drive the calibration plate mounting member 100 to move relative to the camera mounting assembly 200 along the second direction Y. The first direction X is perpendicular to the second direction Y.

[0092] The calibration plate mounting member 100 is driven by the second driving device 600 to move along the second direction Y, so that the camera can take pictures of the calibration plate at different positions, which can improve the inspection accuracy. For example, the camera can take pictures of the calibration plate at the leftmost, middle and rightmost positions of the camera field of view.

[0093] The specific structure of the second driving device 600 is not limited here. Figure 7 As shown, the second driving device 600 may include a second power member 610 and a second rack member 620. The second rack member 620 is fixedly mounted on the second base assembly 500, and the extension direction of the second rack member 620 is parallel to the second direction Y. The second power member 610 is fixedly mounted on the calibration plate mounting member 100 and is in transmission connection with the second rack member 620. In this way, the second power member 610 cooperates with the second rack member 620, and the second power member 610 can drive the calibration plate mounting member 100 to move along the second direction Y.

[0094] For example, Figure 7 As shown, the second power component 610 may include a second drive motor 611 and a second gear 612. The second drive motor 611 is fixedly mounted on the calibration plate mounting component 100. The second gear 612 is sleeved on the motor shaft of the second drive motor 611 and is fixedly connected to the second drive motor 611. The second gear 612 is meshed with the second gear condition 620. The second drive motor 611 is transmission-connected to the first gear condition 320 via the second gear 612.

[0095] During the operation of the second driving device 600, the second driving motor 611 drives the second gear 612 to rotate, and the second gear 612 meshes with the second tooth condition 620 and, under the action of the second tooth condition 620, drives the second driving motor 611 to move along the second direction Y, thereby moving the calibration plate mounting member 100 along the second direction Y.

[0096] In some possible implementations, as shown in the figure, the calibration plate mounting member 100 may include a second cavity 130 and a second opening 140, and the second opening 140 communicates the inside and the outside of the second cavity 130. At least a portion of the second power member 610 is disposed inside the second cavity 130, and the second power member 610 is transmission-connected to the second gear member 620 through the second opening 140. By disposing at least a portion of the second power member 610 inside the second cavity 130, the second power member 610 can be hidden, and the compactness of the second power member 610 and the calibration plate mounting member 100 can be improved.

[0097] Exemplarily, a portion of the second power member 610 is disposed inside the second cavity 130 , and another portion is disposed inside the second opening 140 . Of course, the second power member 610 may also be disposed inside the second cavity 130 .

[0098] Specifically, the second power member 610 includes a second drive motor 611 and a second gear 612. At this time, a part of the second drive motor 611 is arranged inside the second cavity 130, and the other part of the second drive motor 611 and the second gear 612 are both arranged outside the second cavity 130 through the second opening 140.

[0099] In the embodiment of the present disclosure, the specific structure of the second base assembly 500 is not limited here. Figure 7As shown, the second base assembly 500 may include a second support seat 510 and a second elastic shielding member 520 extending along the second direction Y. The second support seat 510 is slidably connected to the calibration plate mounting member 100, and the second support seat 510 includes a second accommodating space. The second elastic shielding member 520 and the second rack member 620 are both arranged inside the second accommodating space, and the second elastic shielding member 520 is located between the calibration plate mounting member 100 and the second rack member 620. The second elastic shielding member 520 includes a fourth opening, and the second rack member 620 is transmission-connected to the second power member 610 through the fourth opening.

[0100] By shielding the second rack member 620 with the second elastic shielding member 520, dust and other foreign matter can be prevented from accumulating on the second rack member 620, thereby affecting the effect of the transmission connection between the second rack member 620 and the second power member 610. In addition, the second rack member 620 is arranged inside the second accommodation space, so that the second rack member 620 can be hidden.
