Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of image acquisition devices, and in particular, to a mirror rotation test tool. Background Art

[0002] Mirror calibration test is an important step in machine vision and photogrammetry, mainly used to determine the relative position relationship between the camera and the mirror and the geometric characteristics of the mirror itself. During the mirror calibration test, when testing whether the rotation angle of the mirror motor is accurate, usually a test board is placed in front of the mirror and on the left and right sides respectively. There will be a certain distance between the test board and the mirror, and this distance is determined according to the application scenario of the mirror. Therefore, in the traditional technology, when performing the mirror calibration test, a large space is required, and the test site requirements are relatively large. For example, if the application scenario of the mirror is a large classroom or a large conference room, then the test board arranged also requires a similar size of the site, resulting in inconvenient calibration tests. At the same time, the price of the standard test board is relatively expensive, and at least three test boards are used for each calibration test, and the cost is also high. Utility Model Content

[0031] The rotating mirror test tool provided by the embodiment of the present application includes a base, a rotating member and an installation position. The rotating member is arranged on the base, and the installation position is formed on the rotating member. The installation position is used to assemble the rotating mirror to be tested.

[0043] In order to better understand the above technical solution, the technical solution of the embodiments of this application will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of this application and the embodiments are detailed descriptions of the technical solution of the embodiments of this application, rather than limitations on the technical solution of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0044] As Figures 1 to 6 shown, an embodiment of this application provides a rotary mirror test tool, including: a base 110; a rotating member 120, the rotating member 120 is rotatably connected to the base 110; a mounting position 130, the mounting position 130 is formed on the rotating member 120, and the mounting position 130 is used to fix the rotary mirror 210.

[0045] The rotating mirror testing tool provided by the embodiment of the present application includes a base 110, a rotating member 120, and a mounting position 130. The rotating member 120 is arranged on the base 110, and the mounting position 130 is formed on the rotating member 120. The mounting position 130 is used to assemble the rotating mirror 210 to be tested. During the testing process of the rotating mirror 210, the base 110 can be set on a flat tabletop, and then the rotating mirror 210 is set on the mounting position 130. A test board is set directly in front of the rotating member 120. During the testing process of the rotating mirror 210, multiple-angle tests are required. The angle of the rotating mirror 210 can be adjusted first to make the rotating mirror 210 rotate to the first detection angle, and then the rotating member 120 is rotated. The angle of rotation of the rotating member 120 is the same as the first detection angle, but the rotation direction is opposite, so that the rotating mirror 210 faces the test board, and then the image of the test board is collected to complete the first-angle test of the rotating mirror 210. Assume that the initial detection angle of the rotating mirror 210 is 0 degrees. At this time, the lens of the rotating mirror 210 is vertically facing the test board directly in front. If the image shooting effect of the rotating mirror 210 in the initial angle test meets the requirements, the rotating mirror 210 is rotated by the first angle and then tested again. At this time, by rotating the rotating member 120 in the opposite direction by the same angle, the detected image taken should be the same as that at the initial detection angle; then the angle of the rotating mirror 210 is adjusted again to make the rotating mirror 210 rotate to the second detection angle, and then the rotating member 102 is rotated again. Similarly, the angle of rotation of the rotating member 120 is the same as the first detection angle, but the rotation direction is opposite to make the rotating mirror 210 face the test board, and then the image of the test board is collected to complete the second-angle rotating mirror test of the rotating mirror 210. Assume that the initial detection angle of the rotating mirror 210 is 0 degrees. At this time, the lens of the rotating mirror 210 is vertically facing the test board directly in front. If the image shooting effect of the rotating mirror 210 in the initial angle test meets the requirements, the rotating mirror 210 is rotated by the second angle and then tested again. At this time, by rotating the rotating member 120 in the opposite direction by the same angle, if the detected image taken at the second detection angle is the same as that at the initial detection angle, it means that the rotating mirror is qualified. Finally, the angle of the rotating mirror 210 can be adjusted again to make the rotating mirror 210 rotate to the third detection angle, and then the rotating member 120 is rotated again. Similarly, the angle of rotation of the rotating member 120 is the same as the first detection angle, but the rotation direction is opposite to make the rotating mirror 210 face the test board, and then the image of the test board is collected again to complete the third-angle test of the rotating mirror. If the detected image taken at the third detection angle is the same as that at the initial detection angle, it means that the rotating mirror is qualified.

[0046] It can be understood that the second angle and the third angle can be two angles with different directions, such as one is biased to the left and the other is biased to the right, so as to better detect the effect of the rotating mirror.

[0047] It can be understood that generally during the testing process of the rotating mirror 210, the parameters of the rotating mirror 210 can be determined by testing the image acquisition effects of the rotating mirror 210 at the left and right extreme positions and the front. Therefore, the measurement of the rotating mirror 210 can usually be completed through three angles. However, the image acquisition of more angles of the rotating mirror 210 can be detected based on actual needs. With the rotating mirror testing tool provided by the embodiments of the present application, after the rotating mirror 210 is adjusted to the angle to be tested, and then the angle of the rotating member 120 is adjusted, the rotating mirror 210 can be oriented towards the test board, and multi-angle measurement can be completed through one test board. The present application does not limit the number of test angles of the rotating mirror 210.

[0048] It can be understood that the captured images at the left or right extreme positions should meet the requirements of the standard images, such as the images being within the field of view.

[0049] The rotating mirror testing tool provided by the embodiments of the present application can adjust the image acquisition direction of the rotating mirror 210 through the setting of the rotating member 120, and multi-angle testing can be realized only through one test board. Through the setting of the rotating member 120, on the one hand, as long as there is enough space in front of the rotating mirror testing tool, even if the space on both sides of the rotating mirror testing tool is relatively narrow, multi-angle calibration of the rotating mirror 210 can be completed, greatly reducing the requirement for a large space during the testing process of the rotating mirror 210 and facilitating the testing of the rotating mirror 210; on the other hand, through the setting of the rotating member 120, only one test board is needed to complete the multi-angle testing of the rotating mirror 210, with low cost.

[0050] As Figure 6 shown, in a feasible implementation manner, the rotating mirror testing tool further includes: a locking member 140, and the locking member 140 is used to position the rotating member 120 on the base 110.

[0051] In this technical solution, the rotating mirror testing tool can further include a locking member 140. Through the locking member 140, the rotating member 120 can be positioned on the base 110. Based on this, during the testing process of the rotating mirror 210, if the rotating member 120 has been adjusted to the expected angle, the rotation can be locked through the locking member 140 to position the rotating member 120 and prevent unexpected rotation of the rotating member 120, ensuring the testing accuracy.

[0052] It can be understood that the rotating member 120 can be arranged above the base 110, and the side of the base 110 facing the rotating member 120 can be a plane. Based on this, without external force, the rotating member 120 generally will not have unexpected rotation, and the probability of affecting the testing accuracy due to accidental touch can be reduced through the setting of the locking member 140.

[0053] As Figure 6As shown, in a feasible implementation, the locking member 140 includes: a damping bearing 141, which is connected to the rotating member 120 and the base 110; an adjusting member 142, which is connected to the damping bearing 141 to adjust the damping degree of the damping bearing.

[0054] In this technical solution, the style of the locking member 140 is further provided. The locking member 140 may include a damping bearing 141 and an adjusting member 142. By providing the damping bearing 141, frictional force can be provided for the rotation of the rotating member 120 relative to the base 110, making the adjustment of the rotation angle of the rotating member 120 relative to the base 110 more accurate. And by providing the adjusting member 142, the damping degree of the damping bearing 141 can be adjusted, that is, the magnitude of the frictional force that the damping bearing 141 can provide can be adjusted. When the frictional force is increased, the rotating member 120 can be locked and positioned. Such a setting facilitates the rotation operation of the rotating member 120, especially enabling precise control of the rotation angle.

[0055] As Figure 6 shown, in a feasible implementation, a first mounting hole 111 is formed on the base 110, a part of the damping bearing 141 is disposed in the first mounting hole 111, a second mounting hole 121 is formed on the rotating member 120, a part of the damping bearing 141 is disposed in the second mounting hole 121, the adjusting member 142 is sunk in the second mounting hole 121, and the second mounting hole 121 penetrates through the rotating member 120.

[0056] In this technical solution, the styles of the base 110 and the rotating member 120 are further provided. By providing the first mounting hole 111 and the second mounting hole 121, a mounting position is provided for the damping bearing 141, facilitating the establishment of a connection relationship among the base 110, the rotating member 120, and the damping bearing 141.

[0057] In this technical solution, by providing the second mounting hole 121 to penetrate through the rotating member 120 and combining with the adjusting member 142 being sunk in the second mounting hole 121, the user can operate the adjusting member 142 above the rotating member 120, making the operation more convenient.

[0058] In some examples, the adjusting member 142 may be a nut or an adjusting ring.

[0059] As Figures 1 to 6 shown, in a feasible implementation, the rotating mirror test tool further includes: a plurality of feet 150, which are connected to the bottom of the base 110.

[0060] In this technical solution, the rotating mirror test tool may further include a plurality of feet 150. By providing the plurality of feet 150, it is convenient to fix the base 110, which can make the setting of the rotating mirror test tool more stable and reduce the influence of the misalignment of the rotating mirror test tool on the test accuracy.

[0061] As Figures 1 to 3 shown, in a feasible implementation, the rotating mirror test tool further includes: a level 160, which is arranged on the base 110; wherein, adjustment holes are formed on the base 110, and the studs 191 of the feet 150 are threadedly connected to the adjustment holes.

[0062] In this technical solution, a level 160 may also be formed on the base 110. Based on this, when the rotating mirror 210 needs to be tested, the effective height of each foot 150 can be adjusted by screwing the studs 191 of the feet 150 first, and then observing the state of the level 160. After the base 110 is in a horizontal state, the rotating mirror 210 can be tested by adjusting the rotating member 120, which can further improve the test accuracy.

[0063] As Figures 1 to 3 shown, in a feasible implementation, the rotating mirror test tool further includes: an identification member 170, which is formed on the rotating member 120; a scale disk 180, which is formed on the base 110. The identification member 170 is used to be arranged opposite to the scale disk 180, and the identification member 170 is used to test the rotation angle of the rotating member 120 relative to the base 110.

[0064] In this technical solution, the rotating mirror test tool may further include an identification member 170 and a scale disk 180. The identification member 170 is arranged on the rotating member 120, and the scale disk 180 is arranged on the base 110. Based on this, when the rotating member 120 is rotated relative to the base 110, it is convenient to know the rotation angle of the rotating member 120, which is conducive to the progress of the test.

[0065] As Figure 4 and Figure 5 shown, in a feasible implementation, on the base 110, the thickness of the area where the identification member 170 is located is less than the thickness of other areas on the base 110. With this setting, the identification member 170 can be closer to the scale disk 180, which is convenient for users to clarify the rotation angle of the rotating member 120 and is conducive to the accurate progress of the test.

[0066] As Figures 1 to 6 shown, in a feasible implementation, the rotating mirror test tool further includes: a fixing component 190, which is formed on the base 110. The fixing component 190 is used to fix the main board, and the main board is used to connect to the rotating mirror 210.

[0067] In this technical solution, the rotating mirror test tool may further include a fixing component 190. By fixing the main board with the fixing component 190 and then connecting the main board to the rotating mirror 210, the probability of the main board loosening or falling can be reduced, ensuring the smooth progress of the test.

[0068] As Figures 1 to 6 shown, in a feasible implementation, the fixing component 190 includes: a plurality of studs 191 disposed on the base 110, and internal threads are formed at the free ends of the studs 191.

[0069] In this technical solution, the style of the fixing component 190 is further provided. The fixing component 190 may include a plurality of studs 191 with internal threads formed thereon. Based on this, the screw is passed through the main board and screwed onto the studs 191, and the main board can be firmly fixed.

[0070] As Figure 6 shown, in a feasible implementation, the rotating mirror test tool further includes: a limiting member 131 formed on the periphery of the installation position 130; a clamping member 132 formed on one side of the installation position 130 close to the edge of the rotating member 120. The limiting member 131 and the clamping member 132 are used to limit the rotating mirror 210.

[0071] In this technical solution, the rotating mirror test tool may further include a limiting member 131 and a clamping member 132. The rotating mirror 210 can be firmly fixed on the installation position 130 by the limiting member 131 and the clamping member 132, which can further improve the test accuracy.
