Patterns include checkerboard, circular array, and dot matrix. In machine vision, it is a key tool for camera calibration, calculating intrinsic and extrinsic parameters. In optical instrument calibration, it ensures instrument accuracy. In autonomous driving, it assists in determining parameters and positional relationships. Calibration plate adjustment devices exist because calibration plates have diverse applications and require flexible operation. These devices precisely control the position and orientation of the calibration plate, working in conjunction with it to complete accurate calibration. The mechanical structure includes translation, rotation, and tilting components to ensure the calibration plate reaches the desired state. In application scenarios, it assists in precise adjustment of the calibration plate, ensuring the smooth progress of testing and experimentation.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1:

[0039] Calibration plate adjustment mechanism, such as Figure 1 , Figure 2 As shown, the system includes an adjustment platform 1, a first driving member 2, a support frame 3, a mounting frame 4, and a second driving member 5. The support frame 3 is slidably connected to the adjustment platform 1. The fixed end of the first driving member 2 is connected to the adjustment platform 1, and the telescopic end of the first driving member 2 is connected to the support frame 3, which allows the support frame 3 to slide horizontally along the adjustment platform 1 to change the horizontal position of the support frame 3. The fixed end of the second driving member 5 is mounted on the support frame 3, and the movable end of the second driving member 5 passes through the support frame 3 and is connected to the mounting frame 4, which drives the mounting frame 4 to rotate. The calibration plate 7 is slidably connected to the mounting frame 4, and a locking device 6 is also connected to one side of the mounting frame 4. The locking device 6 is used to fix the calibration plate 7 after it slides to a suitable position along the mounting frame 4.

[0040] Specifically, such as Figure 2As shown, the adjustment platform 1 has a rectangular structure and serves as the basic structure for supporting and adjusting other components. Slide rails 11 are provided on both sides of the adjustment platform 1. The fixed end of the first driving component 2 is fixed to one end of the adjustment platform 1. The first driving component 2 is a telescopic rod, and its travel direction is parallel to the slide rails 11. The telescopic end of the telescopic rod is connected to one side of the bottom of the support frame 3. The telescopic rod can be extended or retracted as needed to adjust its axial position. Multiple support feet 12 are also connected to the bottom of the adjustment platform 1 for support and cushioning. Multiple decorative strips 13 are also connected to the top of the adjustment platform 1. These decorative strips 13 not only enhance the aesthetics but also provide some protection.

[0041] like Figure 2 As shown, the support frame 3 includes a horizontal plate 31 and a vertical plate 32. The vertical plate 32 is connected to both ends of the horizontal plate 31, and the horizontal plate 31 and the vertical plate 32 form a U-shaped structure with the open end facing upwards. The bottom of the support frame 3 is the horizontal plate 31, and the bottom surface of the horizontal plate 31 is provided with a sliding groove, which can be slidably connected to the slide rail 11 of the adjustment table 1. The sliding groove and the slide rail 11 can be in the form of a rectangular structure or a dovetail groove structure, whichever is available in the prior art. The two sides of the support frame 3 are vertical plates 32. The second driving component 5 is a silent motor. The output shaft of the silent motor is connected to the support frame 3 through a bearing, and the end of the output shaft is connected to the mounting bracket 4. The silent motor provides a smooth and low-noise drive.

[0042] Mounting bracket 4 includes a first mounting rod 41, a second mounting rod 42, and an auxiliary bracket 43. The middle of one side of the first mounting rod 41 is fixedly connected to a silent motor. The auxiliary bracket 43 is rotatably connected to the other side of the support bracket 3 via a bearing. The auxiliary bracket 43 is connected to the second mounting rod 42. The first mounting rod 41 and the second mounting rod 42 are arranged approximately symmetrically. The opposite sides of the first mounting rod 41 and the second mounting rod 42 each have a groove that runs through the length direction. The calibration plate 7 is inserted between the first mounting rod 41 and the second mounting rod 42 along the grooves of the two rods and can be locked from the side by the locking device 6.

[0043] The locking device 6 can be a locking bolt that passes through the second mounting rod 42. By screwing in the bolt, it can abut against the side of the calibration plate 7 to achieve locking.

[0044] In this embodiment, the extension and retraction of the telescopic rod on the adjustment platform 1 controls the horizontal movement of the support frame 3 along the slide rail 11, which in turn drives the calibration plate 7 to move horizontally. The rotation of the second drive component 5 drives the mounting frame 4 to rotate around the output shaft of the silent motor, which in turn drives the calibration plate 7 to rotate, thus adjusting the angle of the calibration plate 7. By inserting the calibration plate 7 into the mounting frame 4 to the appropriate depth, it is locked by the locking device 6 on the side, thereby adjusting the position of the calibration plate 7 on the mounting frame 4. This embodiment has a simple structure, is easy to maintain, reduces costs, is easy to operate, improves work efficiency and accuracy, and meets adjustment requirements.

[0045] Example 2:

[0046] like Figure 3 As shown, based on the above embodiment one, another locking device 6 is provided.

[0047] The left side of the second mounting rod 42 has a groove along the vertical direction; the right side of the calibration plate 7 is connected to a fixing strip 71 along the height direction. The right side of the fixing strip 71 has a T-shaped structure, and the right side of the T-shaped structure has fixing teeth 72, which can be rack-shaped or wavy. The T-shaped structure can be inserted into the slide groove. A through hole is opened along the horizontal direction of the second mounting rod 42, and the through hole connects the groove to the outside.

[0048] like Figure 3 As shown, the locking device 6 includes a rubber strip 61 and a fixing screw 62. The fixing screw 62 is threadedly connected to the through hole. The rubber strip 61 is located in the groove. By screwing the fixing screw 62, the rubber strip 61 can be driven to approach and press against the fixing tooth 72. Since the rubber strip 61 has a certain deformation capacity, it can be appropriately embedded in the tooth groove to improve the fixing effect.

[0049] The rubber strip 61 can be in strip or block shape.

[0050] like Figure 4 As shown, the locking device 6 also includes a force-applying rod 63 and a rubber sleeve 64. Multiple force-applying rods 63 are fixedly connected to the front and rear sides of the fixing screw 62. The outer wall of the force-applying rod 63 is fixedly connected to the rubber sleeve 64. The force-applying rod 63 facilitates the application of force to disassemble and adjust the calibration plate. The rubber sleeve 64 not only enhances the grip of the force-applying rod 63, but also effectively prevents slippage, ensuring the stability and safety of the overall structure.

[0051] In this embodiment, the calibration plate 7 can be slidably installed into the groove by the groove setting. During installation, when the calibration plate 7 is slidably installed into the groove, the rubber strip 61 can be squeezed onto the fixing tooth 72 by tightening the fixing screw 62, so that the rubber strip 61 deforms and fits against the tooth wall, preventing the calibration plate 7 from sliding out. Furthermore, due to this sliding and squeezing fixing method, the structure can be further moved and positioned in the vertical direction as shown in the figure, thereby adjusting the height of the vertical plate. This structure improves the convenience of structural installation and increases flexibility, meeting the installation requirements.

[0052] Example 3:

[0053] like Figure 5 As shown, a controller 8 is also provided based on the above embodiment one or embodiment two.

[0054] Multiple connecting rods 44 are fixedly connected to the middle edge of the left side of the first mounting rod 41. A connecting plate 45 is fixedly connected to the left end of the connecting rod 44. A controller 8 is set on the left side of the connecting plate 45. The controller 8 is electrically connected to the telescopic rod and the silent motor through wires. A display screen 81 is set on the rear left side of the controller 8. Multiple buttons 82 are set on the top front left side of the controller 8. The display screen 81 allows users to clearly see various information and data. The buttons 82 are arranged in an orderly manner to facilitate users to perform various operations. A power button 83 is set on the bottom front left side of the controller 8. The power button 83 is a circular block.

[0055] The second drive unit 5 can be connected to the middle position of multiple connecting rods 44.

[0056] In this embodiment, a controller 8 is provided, thereby achieving precise control of the entire device.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
