[0043] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0044] As Figures 1 to 14 shown, a calibration device 7 disclosed in an embodiment of the present application includes:

[0045] a calibration frame 1;

[0046] a calibration table 2 fixedly connected to the calibration frame 1, a fixing member 201 provided on the tabletop of the calibration table 2, the fixing member 201 being used to fix the module housing 3 of the camera to be detected. After the fixing member 201 is fixed to the module housing of the camera to be calibrated, the height of the module housing of the camera to be calibrated from the ground on the calibration table 2 is the same as the height of the module housing of the camera to be calibrated installed on the robot from the ground.

[0047] Among them, the calibration frame 1 is the main structure of the entire calibration device 7. Its main function is to be connected to the calibration table 2 of the module housing 3 for placing the camera to be detected, and at the same time, it can stand upright on the ground. The middle of the calibration frame 1 is in a hollow state, and the entire structure is formed through the connection of columns; the calibration table 2 can be a tabletop structure. By setting a fixing member 201 on its tabletop for specifically fixing the module housing of the camera to be calibrated, the module housing of the camera to be calibrated can be of various types, such as the module housing 301 on the head of a lawn mower, the module housing on the main host module (the module for security monitoring), the module housing 305 on the head of a snow sweeper, the module housing 303 on the head of a leaf blower, the module housing 304 on the rear of the vehicle (a housing containing a camera is set on the rear of the vehicle body), etc. In the case of inconsistent module housings, the number and structure of the fixing members 201 on the calibration table 2 can be different;

[0048] In addition, after the module housing of the camera to be calibrated is fixed by the fixing member 201 on the calibration table 2, its height from the ground is the same as the height from the ground when the module housing is actually installed on the robot. In this way, when calibrating the camera on the calibration device 7 through the calibration software, the calibration process is closer to the actual use scenario of the component to be calibrated;

[0049] It should be noted that in this solution, after calibration is completed through the calibration device 7, the performance of the camera component can be detected by the detection device. Finally, after the performance detection is correct, the module housing containing the camera component can be installed on the robot;

[0050] In this embodiment, the module housing of the camera to be calibrated is fixed by the fixing member 201 in the specifically set calibration device 7, which increases the stability during the calibration process. At the same time, the height from the ground of the module housing of the camera to be calibrated on the calibration table 2 is the same as the height from the ground when the module housing of the camera to be calibrated is installed on the robot, and the calibration process is closer to the actual use scenario. In this way, not only can the calibration efficiency of the camera component be improved, but also the subsequent detection efficiency and installation efficiency can be improved.

[0051] As Figure 3 and Figure 6 shown, in an embodiment, a first clamping post 202 and a second clamping post 203 are provided on the tabletop of the calibration table 2. Clamping notches are provided on the first clamping post 202 and the second clamping post 203. The first clamping notches 20201 of the two relatively arranged first clamping posts 202 clamp the housing 5 of the camera component to be calibrated, and the second clamping notches 20231 of the two relatively arranged second clamping posts 203 clamp the board 6 of the camera component to be calibrated.

[0052] Among them, the first clamping post 202 and the second clamping post 203 can be arranged in one area of the tabletop. Two first clamping posts 202 are arranged in a relatively set form, and two second clamping posts 203 are arranged in a relatively set form. The corresponding shell or board is clamped through the clamping notch arranged at one end of the column body, and one end of the column body is fixedly connected to the tabletop of the calibration table 2. In this way, when detecting the camera component subsequently, the stability of the component to be detected in the detection device can be improved;

[0053] In addition, the second clamping post 203 is mainly used to detect whether the camera is clear after the camera component board is fixed to the inspection device, and the first clamping post 202 is mainly used to embed and install the camera component board into the camera component housing after the camera component housing is fixed.

[0054] Such as Figure 3 and Figure 6 As shown in, in an embodiment, the fixing member 201 includes a first fixing post 2011 and a second fixing post 2012. A third clamping notch 20111 is formed on the first fixing post 2011, and the third clamping notch 20111 is clamped to the module housing of the camera to be calibrated; the second fixing post 2012 is arranged at an interval from the first fixing post 2011, and a first convex head 20121 is provided on the second fixing post 2012, and the first convex head 20121 is adaptively installed in the opening of the module housing of the camera to be calibrated.

[0055] Among them, one ends of the first fixing post 2011 and the second fixing post 2012 are both fixedly connected to the tabletop of the calibration table 2, and the other ends are provided with structures that can be connected to the upper shell in the module housing of the camera to be calibrated, including opening a clamping notch at the top end of the first fixing post 2011. The surface where the clamping notch is located can be an inclined surface (set according to the shape of the module housing, such as the module housing 301 on the lawn mower head, and the inclined surface faces the module housing), and also includes the convex head provided at the top end of the second fixing post 2012. The shape of the convex head is adaptively installed with the opening of the module housing of the camera to be calibrated. The opening can be the position where the sensor is installed in the module housing of the camera to be calibrated, such as the installation position of the rain sensor; in this way, the module housing of the camera to be calibrated can be limited and clamped through the first fixing post 2011 mentioned above, and the module housing of the camera to be calibrated can be firmly connected through the second fixing post 2012 mentioned above, improving the stability of the component to be detected in the detection device.

[0056] Such as Figure 6As shown, in one embodiment, the fixing member 201 includes a first adsorption fixing column 2013, and a first adsorption magnet 20131 is disposed inside the first adsorption fixing column 2013. A second adsorption magnet 301 is disposed inside a handle 8 of the module housing of the camera to be calibrated, which is adapted to the first adsorption magnet 20131 in the first adsorption fixing column 2013.

[0057] Wherein, one end of the first adsorption fixing column 2013 is fixedly connected to the tabletop of the calibration table 2, and the other end is magnetically connected to the handle 8 of the module housing of the camera. The module housing of the camera to be calibrated is fixed between the handle 8 and the first adsorption fixing column 2013. The number of the first adsorption fixing columns 2013 can be set according to requirements. Preferably, two first adsorption fixing columns 2013 are disposed in a region symmetrical to the module housing of the calibration camera and the handle 8. The position of the handle 8 (which can be an arched structure) can be in the middle region of the module housing of the camera to be calibrated. Magnets capable of performing adsorption are disposed inside both the handle 8 and the first adsorption fixing column 2013. Under the principle of opposite-sex attraction, the module housing of the camera to be calibrated can be clamped between the handle and the first adsorption fixing column 2013. Thus, the stability of the component to be detected in the detection device can be improved by the magnetic attraction between the first adsorption fixing column 2013 and the handle 8.

[0058] As Figure 6 As shown, in one embodiment, the fixing member 201 includes a second adsorption fixing column 2014, and a third adsorption magnet (not shown in the figure) is disposed inside the second adsorption fixing column 2014. A fourth adsorption magnet (not shown in the figure) is disposed inside an operating member 9 of the module housing of the camera to be calibrated, which is adapted to the third adsorption magnet 301 in the first adsorption fixing column 2013.

[0059] Wherein, one end of the second adsorption fixing column 2014 is fixedly connected to the tabletop of the calibration table 2, and the other end is magnetically connected to the operating member 9 of the module housing of the camera. The module housing of the camera to be calibrated is fixed between the operating member 9 and the second adsorption fixing column 2014. The number of the second adsorption fixing columns 2014 can be set according to requirements. Preferably, two second adsorption fixing columns 2014 are disposed in a region corresponding to the module housing of the calibration camera and the operating member 9. The position of the operating member 9 can be in the middle region of the module housing of the camera to be calibrated. Magnets capable of performing adsorption are disposed inside both the operating member 9 and the second adsorption fixing column 2014. Under the principle of opposite-sex attraction, the module housing of the camera to be calibrated can be clamped between the operating member 9 and the second adsorption fixing column 2014. Thus, the stability of the component to be detected in the detection device can be improved by the principle of magnetic attraction between the second adsorption fixing column 2014 and the operating member 9;

[0060] It should be noted that the operating member 9 can be a cylindrical operating structure. The user can hold the surface of the cylinder to control the module housing of the camera to be calibrated. In addition, the first fixing column 2011 and the second fixing column 2012 (as a whole), the first adsorption fixing column 2013, and the second adsorption fixing column 2014 can be selected to fix the module housing of the camera to be calibrated simultaneously, or one of them can be selected to fix the module housing of the camera to be calibrated; the first adsorption fixing column 2013 and the second adsorption fixing column 2014 can be applied to the module housing 301 on the lawn mower head.

[0061] As Figure 1 and Figure 6 shown, in an embodiment, the fixing member 201 further includes a clamping block 2015. A clamping groove 2016 is provided on the tabletop of the calibration table 2. The clamping groove 2016 is clamped with the module housing of the camera to be calibrated, and the clamping block 2015 is arranged on both sides of the clamping groove 2016.

[0062] Among them, a connection position (such as a screw connection position) that can be connected to the tabletop of the calibration table 2 is provided inside the clamping block 2015. The setting of the clamping groove 2016 can clamp the bottom shell of the light board or / and the camera component to be detected. In this way, the light board or / and the camera component can be firmly clamped in the clamping groove 2016. Clamping blocks 2015 fixedly connected to the upper end surface of the bearing surface are arranged on both sides of the clamping groove 2016, and the clamping blocks 2015 can limit and stabilize the light board or / and the camera component;

[0063] The clamping block 2015 can be used in combination with the first fixing column 2011 and the second fixing column 2012, the clamping block 2015 can be used in combination with the first adsorption fixing column 2013 and the third adsorption magnet 301, the clamping block 2015 can be used in combination with the second adsorption fixing column 2014 and the fourth adsorption magnet 302, and the clamping block 2015 can also be used in combination with the first fixing column 2011, the second fixing column 2012, the first adsorption fixing column 2013, the third adsorption magnet 301, the second adsorption fixing column 2014, and the fourth adsorption magnet 302. In this way, each set of usage schemes can improve the stability of the component to be detected in the detection device.

[0064] As Figure 5 shown, in an embodiment, the first adsorption fixing column 2013 includes a first connecting strip 20132 and a first adsorption strip 20133. One end of the first adsorption strip 20133 is fixedly connected to one end of the first connecting strip 20132. The first adsorption magnet 20131 is arranged inside the other end of the first adsorption strip 20133, and the other end of the first connecting strip 20132 is fixedly connected to the calibration table 2.

[0065] As Figure 4As shown, in one embodiment, the second adsorption and fixing column 2014 includes a second connecting strip 20141 and a second adsorption strip 20142. One end of the second adsorption strip 20142 is fixedly connected to one end of the second connecting strip 20141. The third adsorption magnet 301 is disposed inside the other end of the second adsorption strip 20142. The other end of the second connecting strip 20141 is fixedly connected to the calibration table 2.

[0066] Among them, the connecting strip and the adsorption strip are in a connecting relationship. The two can be connected to form a right-angle support relationship. A magnet is disposed inside the adsorption strip. One end of the connecting strip is connected to the adsorption strip, and the other end is fixedly connected to the surface of the calibration table 2. In addition, the connecting strip and the adsorption strip in the first adsorption and fixing column 2013 can be disposed below the camera assembly housing of the module housing. The connecting strip and the adsorption strip in the second adsorption and fixing column 2014 can be disposed on the left and right sides of the module housing.

[0067] As Figure 7 and Figure 8 As shown, in one embodiment, a bottom surface 4 opposite to the calibration table 2 is provided on the calibration frame 1. A third clamping post 401 is provided on the bottom surface 4. The third clamping post 401 is provided with a fourth clamping notch 40401. The fourth clamping notch 40401 is clamped to the bottom shell of the module housing of the camera to be calibrated to support the module housing of the camera to be calibrated. The fixing member 201 includes a third fixing column 2017. A second convex head 20171 is provided on the second fixing column 2012. The second convex head 20171 is adaptively installed in the opening of the module housing of the camera to be calibrated.

[0068] Among them, one end of the third clamping post 401 is fixedly connected to the bottom surface 4 opposite to the calibration table 2, and a structure - a clamping notch - that can be connected to the module housing of the camera to be calibrated is provided at the other end. A clamping notch is provided in the middle area at the head end of the third clamping post 401. The number of the third clamping posts 401 can be set according to requirements. Preferably, two third clamping posts 401 connected to the bottom shell position of the module housing of the camera to be calibrated are provided on the bottom surface 4. One end of the third fixing column 2017 is fixedly connected to the surface of the calibration table 2, and a structure that can be connected to the module housing of the camera to be calibrated is provided at the other end, including a convex head provided at the top end of the third fixing column 2017. The shape of the convex head is adaptively installed in the opening of the upper shell in the module housing of the camera to be calibrated. This opening can be the position for installing a sensor in the module housing of the camera to be calibrated, such as the installation position of a rain sensor. Thus, the module housing of the camera to be calibrated can be limited and clamped by the above-mentioned third clamping post 401, and the module housing of the camera to be calibrated can be firmly connected by the above-mentioned third fixing column 2017, improving the stability of the component to be detected in the detection device.

[0069] It should be noted that the third card-connecting post 401 and the third fixing post 2017 can be applied to the module housing 302 (module for security monitoring) on the host module.

[0070] Such as Figure 9 and Figure 10 As shown, in an embodiment, the fixing member 201 includes a fourth fixing post 2018.

The fixing member 201 includes a fixing base 2020 and a fixing screw 2021 fixedly connected to the fixing base 2020. The fixing screw 2021 is looped with a spring 2023. When the fixing base 2020 moves upward relative to the fixing screw 2021, the spring 2023 provides an elastic force that presses the fixing base 2020 downward.

[0074] Among them, the fixed seat 2020 is fixedly connected to the tabletop where the calibration table 2 is located through the fixing screw 2021. The tabletop of this calibration table 2 is a vertical surface, and the middle area of this surface is a hollow space. The module housing of the camera to be calibrated is placed in this hollow space and fixed by the fixing member 201. A spring 2023 is provided around the fixing screw 2021. When the fixed seat 2020 moves upward towards the fixing screw 2021, the spring 2023 provides an elastic force that presses the fixed seat 2020 downward. In this way, by changing the direction of the fixed seat 2020, the module housing of the camera to be calibrated can be fixed by the fixed seat 2020.

[0075] As Figure 11 and Figure 12 As shown in [figures], in one embodiment, a hollow space is provided in the middle area of the calibration table 2; the fixed seat 2020 includes a first side 2024 and a second side 2025. When the first side 2024 of the fixed seat 2020 is in the first direction and the second side 2025 is in the second direction, the fixed seat 2020 fixes the module housing of the camera to be calibrated in the hollow space.

[0076] Among them, the length and width sides of the fixed seat 2020 are inconsistent. When the first side 2024 of the fixed seat 2020 is in the first direction and the second side 2025 of the fixed seat 2020 is in the second direction, the second side 2025 can fix the module housing of the camera to be calibrated. In addition, fixing members 201 can be provided in four areas of the calibration table 2. Among them, the first direction and the second direction are in a perpendicular relationship;

[0077] It should be noted that the fixed seat 2020 and the fixing screw 2021 fixedly connected to the fixed seat 2020 can be applied to the module housing 304 on the rear of the vehicle.

[0078] As Figure 13 and Figure 14 As shown in [figures], in one embodiment, the fixing member 201 includes a sixth fixing post 2026. The sixth fixing post 2026 is provided with a sixth clamping notch 20261 adapted to the module housing. The sixth fixing post 2026 is inclined and installed on the module housing of the camera to be calibrated, and the sixth clamping notch 20261 is clamped to the module housing of the camera to be calibrated.

[0079] Among them, one end of the sixth fixing post 2026 is fixedly connected to the tabletop of the calibration table 2, and a structure - clamping notch is provided at the other end that can be connected to the upper shell of the module housing of the camera to be calibrated. The sixth fixing post 2026 is inclined to be adapted to the shape of the module housing of the camera to be calibrated; in this way, clamping the component to be detected through the clamping notch can improve the stability of the component to be detected in the detection device.

[0080] As Figure 13 andFigure 14 As shown, in one embodiment, the fixing member 201 includes a third adsorption fixing column 2027 and a fourth adsorption fixing column 2028. The fifth adsorption magnet 20271 in the third adsorption fixing column 2027 is adsorbed and fixed to the sixth adsorption magnet 20281 in the fourth adsorption fixing column 2028 through the lamp board mounting opening in the module housing of the camera to be calibrated.

[0081] Among them, adsorption magnets are provided inside both the third adsorption fixing column 2027 and the fourth adsorption fixing column 2028. The module housing of the calibrated camera is clamped and fixed by the principle of attracting opposite poles as mentioned above. In this way, the stability of the component to be detected in the detection device can be improved by the principle of magnetic attraction.

[0082] It should be noted that the third adsorption fixing column 2027 and the fourth adsorption fixing column 2028 can be applied to the module housing 305 on the snowplow locomotive head.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above.
