Technical Field
[0001] This utility model relates to the field of camera debugging technology, and more specifically, to a camera debugging bracket. Background Technology
[0002] With the development of autonomous driving technology, cameras, as core sensing devices for achieving intelligent driving functions in automobiles, have received increasing attention. Vehicle-mounted cameras primarily acquire image information through lenses and image sensors, enabling 360° visual perception and compensating for the limitations of radar in object recognition. They are the sensors closest to human vision. Vehicle-mounted cameras can be divided into in-cabin cameras and external cameras. Regardless of the type, vehicle-mounted cameras require multiple rounds of debugging before mass production to achieve optimal image quality.
[0003] During the camera's development phase, engineers need to take photos of specific charts to fine-tune the camera's image quality, such as for sharpness testing, grayscale testing, and field-of-view distortion testing. The testing process mostly uses simple stands to fix the camera in place. Ordinary stands can only adjust the approximate position of the camera, not its precise location. Furthermore, when replacing one camera after it has been fine-tuned, the camera's position needs to be readjusted again. This not only affects the accuracy of image quality tuning but also increases the workload for the technicians, causing significant inconvenience.
[0004] Current camera debugging brackets are designed only for certain camera structures or specific vehicle models, resulting in poor applicability and limited flexibility, which restricts the debugging process. Some debuggers use handmade brackets, which can be adjusted in multiple degrees of freedom, but can only adjust the approximate position and cannot precisely adjust and record the position, affecting the accuracy and efficiency of camera image quality debugging.
[0005] Therefore, how to improve the debugging efficiency of cameras has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation
[0058] The core of this utility model lies in disclosing a camera debugging bracket to improve the debugging efficiency of cameras.
[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0060] like Figure 1 and Figure 9 As shown in the figure, this utility model embodiment discloses a camera debugging bracket, including a clamp 100, a pitch angle adjustment device 300, a yaw angle adjustment device 400, a lifting device 500, and a translation device 600.
[0061] The clamp 100 is used to fix the camera 200, specifically as follows: Figure 9 As shown. The pitch angle adjustment device 300 is connected to the clamp 100. By adjusting the pitch angle of the clamp 100, the pitch angle of the camera 200 is adjusted. Here, pitch angle refers to... Figure 9 The rotation angle along the y-axis is shown in the diagram. The yaw angle adjustment device 400 is connected to the pitch angle adjustment device 300 and is used to adjust the yaw angle of the camera 200. Here, the yaw angle refers to... Figure 9 The rotation angle along the z-axis. The lifting device 500 is connected to the yaw angle adjustment device 400 and is used to adjust the height of the camera 200, that is, to adjust the displacement of the camera 200 along the z-axis. The translation device 600 is connected to the lifting device 500 to drive the camera 200 to translate along a first direction and a second direction. The second direction is perpendicular to the first direction. The first direction refers to one of the x-axis direction and the y-axis direction in the figure, and the second direction refers to the other of the x-axis direction and the y-axis direction. For ease of explanation, the first direction will be the x-axis direction and the second direction will be the y-axis direction in the following explanation.
[0062] The camera debugging bracket disclosed in this embodiment of the utility model has a simple structure. It allows adjustment of the camera 200's pitch angle via the pitch angle adjustment device 300, the yaw angle via the yaw angle adjustment device 400, the height via the lifting device 500, and the displacement of the camera 200 in the x-axis and y-axis directions via the translation device 600, according to debugging needs. The camera 200 has translational freedom in the x-axis, y-axis, and z-axis directions, and rotational freedom in the y-axis and z-axis directions. This large degree of freedom simplifies the adjustment process, reduces the workload of adjusting the camera 200, and improves debugging efficiency. It is suitable for debugging camera 200 needs in various scenarios. The setup of the pitch angle adjustment device 300, yaw angle adjustment device 400, lifting device 500, and translation device 600 ensures that the camera 200 is placed in the correct position on the chart, while also improving debugging accuracy.
[0063] Furthermore, such as Figures 1-3 As shown, the clamp 100 includes a first clamping member 110, a second clamping member 120, and a fixing plate 130. The first clamping member 110 and the second clamping member 120 are arranged opposite to each other, forming a clamping space for the camera 200. At least one of the first clamping member 110 and the second clamping member 120 slides in cooperation with the fixing plate 130 to improve the applicability to cameras 200 of various sizes.
[0064] To reduce the possibility of scratching the camera 200, in some specific embodiments, rubber pads 140 are provided on the sidewalls of the first clamping member 110 and the second clamping member 120 facing the camera 200. The rubber pads 140 can increase the friction between the first clamping member 110 and the second clamping member 120 and the camera 200, provide a buffering effect, and reduce the possibility of scratching the camera 200.
[0065] Furthermore, such as Figures 1-3As shown, in some specific embodiments, both the first clamping member 110 and the second clamping member 120 are slidably engaged with the fixing plate 130. Specifically, the first clamping member 110 and the second clamping member 120 can move closer to or further away from each other, and their positions can be adjusted according to the size of the camera 200 to accommodate the fixing requirements of cameras 200 of different sizes. The fixing plate 130 is provided with a first slide rail 131 and a second slide rail 132. The first clamping member 110 is slidably engaged with the first slide rail 131, and the second clamping member 120 is slidably engaged with the second slide rail 132. Preferably, the first slide rail 131 and the second slide rail 132 are arranged collinearly, so that the first clamping member 110 and the second clamping member 120 move closer to or further away from each other along the same straight line. To prevent the camera 200 from falling during the debugging process, the first clamping member 110 and the second clamping member 120 are preferably located in the center of the fixing plate 130. The first clamping member 110 and the second clamping member 120 can be clamping rods or clamping plates to adapt to cameras 200 with different outer contour shapes.
[0066] Specifically, such as Figure 3 As shown, taking the second clamping member 120 as an example, the second clamping member 120 includes a first clamping part 121 and a second clamping part 122. A sliding hole 123 is provided between the first clamping part 121 and the second clamping part 122 to slide and engage with the second slide rail 132. The first end of the first clamping part 121 is fixedly connected to the first end of the second clamping part 122. A gap is provided between the second end of the first clamping part 121 and the second end of the second clamping part 122 to communicate with the sliding hole 123, so as to install the second clamping member 120. On the second slide rail 132, the second end of the first clamping part 121 and the second end of the second clamping part 122 are connected by a first fastener 125. The first fastener 125 is preferably a bolt, which is threaded into one of the first clamping parts 121 and the second clamping part 122. By tightening or loosening the bolt, the second clamping member 120 and the second slide rail 132 are locked (relatively fixed) or unlocked (relatively sliding). When unlocked, the second clamping member 120 can slide along the fixing plate 130. After adjustment, by tightening the bolt, the gap 124 is reduced, achieving relative fixation between the second clamping member 120 and the second slide rail 132. Alternatively, the second fastener 111 can also be a bolt and nut combination; by tightening the nut, the second clamping member 120 and the second slide rail 132 can be locked and unlocked.
[0067] It should be noted that the first clamping member 110 and the second clamping member 120 are arranged symmetrically and have the same structure, which will not be described in detail here. The first clamping member 110 is provided with a second fastener 111 to realize the locking and unlocking of the first clamping member 110 and the first slide rail 131.
[0068] Furthermore, in some other specific embodiments, a threaded rod can be provided on the fixing plate 130, and threaded portions with opposite directions of rotation are provided on both sides of the threaded rod. The first clamping member 110 and the second clamping member 120 respectively cooperate with the threaded portions on both sides of the threaded rod. One end of the threaded rod is provided with a handle or is connected to the drive motor. By rotating the threaded rod, the first clamping member 110 and the second clamping member 120 are brought closer or further apart to clamp the camera 200 or release the clamping of the camera 200.
[0069] Furthermore, such as Figures 1-2 and Figure 4 As shown, the pitch angle adjustment device 300 includes a fixed bracket 310 and a rotary table 320. The fixed bracket 310 is connected to the fixed plate 130, which can be achieved by welding or by fasteners. A pitch angle pivot 321 is provided on the fixed bracket 310, and the fixed bracket 310 is rotatably connected to the pitch angle pivot 321. The fixed bracket 310 includes two opposing bracket plates 313, which, together with the pitch angle pivot 321, form an H-shape. A pitch angle pivot hole 323 is provided on the rotary table 320, through which the pitch angle pivot 321 passes and is rotatably connected to the fixed bracket 310. To provide clearance for the rotation of the fixed bracket 310 along the pitch angle pivot 321, the top of the rotary table 320 is arc-shaped, specifically as shown below. Figure 4 As shown. In order to read and record the pitch angle of the camera 200, a first scale 322 is provided on the rotary table 320, and a scale reading hole 312 corresponding to the first scale 322 is provided on the fixed bracket 310.
[0070] Furthermore, such as Figure 2 As shown, to fix the camera 200 after the tilt angle adjustment is completed, a first stop 311 is provided on the fixing bracket 310. Specifically, the first stop 311 can be a bolt. The fixing bracket 310 has a threaded hole, and the first stop 311 is threaded into the threaded hole. By screwing the first stop 311, the rotating table 320 abuts against the fixing bracket 310, thereby restricting the rotation of the camera 200. When it is necessary to adjust the tilt angle of the camera 200, the first stop 311 is loosened, the entire clamp 100 is rotated, and after adjustment, it is fixed by screwing the first stop 311.
[0071] Furthermore, such as Figure 1 and Figures 4-5As shown, the yaw angle adjustment device 400 includes a yaw angle shaft 410 and a shaft base 420. The first end of the yaw angle shaft 410 is connected to the rotary table 320, which can be achieved through welding, fastener connection, or the first end of the yaw angle shaft 410 and the rotary table 320 being an integral structure. The second end of the yaw angle shaft 410 is rotatably connected to the shaft base 420. Specifically, the shaft base 420 has a shaft groove 423, and the second end of the yaw angle shaft 410 has a protrusion that mates with the shaft groove 423. This design prevents the yaw angle shaft 410 from detaching from the shaft base 420 during rotation. To facilitate reading and recording the yaw angle of the camera 200, a second scale 422 is provided on the shaft base 420.
[0072] like Figure 5 As shown, in order to fix the camera 200, a second stop 421 is provided on the pivot base 420. The second stop 421 can be a bolt. The pivot base 420 has a threaded hole that mates with the bolt. After the yaw angle of the camera 200 is adjusted to the correct position, the second stop 421 is rotated so that it abuts against the yaw angle pivot 410 to limit the rotation of the yaw angle pivot 410 relative to the pivot base 420, thereby fixing the camera 200.
[0073] When it is necessary to adjust the yaw angle of the camera 200, the relative position of the yaw angle pivot 410 and the pivot base 420 can be adjusted by turning the second stop 421. By rotating the yaw angle pivot 410, the yaw angle of the camera 200 can be adjusted. After the adjustment is in place, turn the second stop 421 to fix the camera 200.
[0074] Furthermore, such as Figures 5-7As shown, the lifting device 500 includes a lifting platform 510, a screw 520, a lifting base 540, and positioning pins 530. The lifting platform 510 is connected to the rotating shaft base 420, which can be achieved by welding or by fasteners. The lifting base 540 is located on the side of the lifting platform 510 away from the rotating shaft base 420. The first end of the screw 520 is threaded into the lifting platform 510, and the lifting platform 510 has a corresponding threaded hole 511. The positioning pins 530 are connected to the lifting base 540 and the translation device 600, respectively. The lifting platform 510 and the positioning pins 530 are slidably engaged. Preferably, the positioning pins 530 include a first positioning pin 531 and a second positioning pin 532, which are respectively located on both sides of the screw 520. The extension direction of the first positioning pin 531 and the second positioning pin 532 is the same as the axial direction of the screw 520, both along the z-axis. The lifting platform 510 has a first positioning hole 512 and a second positioning hole 513 that mate with the first positioning post 531 and the second positioning post 532. When it is necessary to adjust the height of the camera 200, the lifting platform 510 slides along the first positioning post 531 and the second positioning post 532 by rotating the screw 520, thereby adjusting the height of the camera 200. The first positioning post 531 and the second positioning post 532 provide a guiding function, allowing the camera 200 to move only along the z-axis. It should be noted that only one positioning post 530 can be provided.
[0075] To facilitate reading and recording the displacement of the camera 200 in the reverse direction along the z-axis, a first scale 5311 is provided on the positioning post 530. The first scale 5311 can be set on either the first positioning post 531 or the second positioning post 532.
[0076] To facilitate the rotation of the screw 520, the second end of the screw 520 is provided with a first handwheel 521 or is connected to the drive motor.
[0077] When the height of camera 200 needs to be adjusted, the lifting platform 510 can be raised and lowered along the z-axis by rotating the screw 520, thereby driving camera 200 to rise and fall.
[0078] Furthermore, in some other specific embodiments, the lifting device 500 can be a drive cylinder, with the piston rod of the drive cylinder connected to the rotating shaft base 420. The height of the camera 200 can be adjusted by extending and shortening the piston rod, that is, the camera 200 can be translated along the z-axis. Of course, other types of lifting devices 500 can also be used, which will not be described in detail here.
[0079] Furthermore, such as Figure 7As shown, the translation device 600 includes a first-direction translation component 610 and a second-direction translation component 620. A positioning post 530 is connected to the first-direction translation component 610, which drives the camera 200 to move along a first direction. The first-direction translation component 610 and the second-direction translation component 620 are slidably connected, and the second-direction translation component 620 drives the camera 200 to move along a second direction. The translation device 600 enables two-dimensional movement of the camera 200 along both the x-axis and y-axis directions.
[0080] Furthermore, such as Figure 7 As shown, the first-direction translation component 610 includes a first base 611, a first lead screw 612, a first slider 613, and a first guide post 614. The first lead screw 612 is rotatably connected to the first base 611 and extends along a first direction. The first slider 613 is threadedly engaged with the first lead screw 612. A positioning post 530 is connected to the first slider 613. The first guide post 614 is connected to the first base 611, and the extension direction of the first guide post 614 is the same as the extension direction of the first lead screw 612. The first slider 613 is slidably engaged with the first guide post 614. When the camera 200 needs to move along the x-axis, the first slider 613 moves along the extension direction of the first guide post 614 by rotating the first lead screw 612. For easy adjustment, a second handwheel 615 is provided at one end of the first lead screw 612 or it is connected to a drive motor. For easy reading of the displacement of the camera 200 along the first direction, a second scale 616 is provided on the first base 611. The first guide post 614 preferably includes two located on both sides of the first lead screw 612.
[0081] In other specific embodiments, the piston rod of the driving cylinder can be connected to the first slider 613, and the camera 200 can be translated along the first direction (x-axis direction) by the extension and retraction of the piston rod. Alternatively, the first slider 613 can be slidably engaged with the first guide post 614, and the first slider 613 can be provided with a limit member, as long as it can drive the first slider 613 to translate along the first direction.
[0082] Furthermore, such as Figure 7As shown, the second-direction translation component 620 includes a second base 621, a second lead screw 622, a second slider 623, and a second guide post 624. Specifically, a third scale 626 is provided on the second base 621. The second lead screw 622 is rotatably connected to the second base 621 and extends along the second direction. One end of the second lead screw 622 is provided with a third handwheel 625 or is connected to a drive motor. The second slider 623 is connected to the first base 611 and threadedly engaged with the second lead screw 622. The second guide post 624 is connected to the second base 621, and its extension direction is the same as that of the second lead screw 622. The first base 611, together with the second slider 623, is slidably engaged with the second guide post 624. Preferably, the second guide post 624 includes two posts disposed on both sides of the second lead screw 622. When it is necessary to adjust the displacement of the camera 200 along the y-axis, the second lead screw 622 is rotated to move the second base 621 along the second direction, thereby driving the camera 200 to move along the second direction. The displacement of the camera 200 along the y-axis is read and recorded by the third scale 626.
