In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] Embodiment 1

[0041] The working principle of the above technical solution is as follows: the left and right cameras of the binocular camera are respectively installed in the two camera limiting components. By changing the positions of the slider 1 7 and the slider 2 9 on the horizontal frame 1, the distance between the two camera limiting components is changed, and the distance between the left and right cameras of the binocular camera is adjusted. The camera corresponding to the slider 1 7 corresponds to the zero scale position on the ruler 10, and the camera corresponding to the slider 2 9 corresponds to the current scale position of the ruler 10. The scale degree is the distance between the left and right cameras. The current scale degree is calibrated in real time by the infrared transmitter 11 to improve the accuracy of camera adjustment, provide a basis for the external parameter adjustment of the binocular camera, and solve the problem that when the existing binocular camera is used, the camera cannot accurately adjust the distance according to the state of the target object, and the external parameter cannot be accurately fed back after adjustment.

[0044] The horizontal frame 1 is fixedly connected to the motor bracket 2, the motor bracket 2 is fixedly connected to the motor 1 3, the output end of the motor 1 3 is connected to the rotating wheel 4, and the motor bracket 2 is fixedly connected to the angle adjustment component;

[0045] The motor 1 3 is electrically connected to the infrared transmitter 11;

[0046] The working principle of the above technical solution is as follows: start the motor 1 3, drive the rotating wheel 4 to rotate, drive the rotating rod 1 5 to rotate, drive the rotating rod 2 6 and the rotating rod 3 8 to rotate, and then drive the slider 1 7 and the slider 2 9 to move together or apart with the rotating wheel 4 as the center, thereby changing the distance between the slider 1 7 and the slider 2 9, and then changing the distance between the two camera limit components. Then the distance between the left and right cameras is adjusted, the scale on the ruler 10 corresponding to the lower end of the slider 2 9 changes, and the infrared transmitter 11 reads the scale at this time, which is the distance between the left and right cameras.

[0047] Embodiment 3

[0048] like Figure 1-18 As shown, the camera limiting component includes a housing 12, a turntable 13 is rotatably connected inside the housing 12, the housing 12 and the turntable 13 are concentrically arranged, and a center hole 64 is penetrated at the center position, four limiting grooves 14 are fixed inside the housing 12, and the four limiting grooves 14 are slidably connected to the turntable 13;

[0049] The camera limiting component also includes four slide bars 15, one end of each of the four slide bars 15 slides in the four limiting grooves 14, an eccentric wheel 16 is fixed to the other end of the slide bar 15, an eccentric column 18 is fixed inside the eccentric wheel 16, the eccentric column 18 is located on the eccentric wheel 16 near the eccentric position of the slide bar 15, and a rubber ring 17 is sleeved on the eccentric wheel 16;

[0050] A spring 19 is provided in the housing 12, one end of the spring 19 is fixed in the housing 12, and the other end of the spring 19 is fixed on the turntable 13. A lever 20 is fixed on the side of the turntable 13, and the lever 20 extends out of the housing 12.

[0051] The working principle of the above technical solution is as follows: the lever 20 is pushed to the other side, the turntable 13 is driven to rotate, the spring 19 is driven to be stretched, the eccentric column 18 moves with the turntable 13, the slide bar 15 and the eccentric wheel 16 are driven to rotate, the end of the slide bar 15 is driven to slide in the limit groove 14, and the part of the volume of the eccentric wheel 16 protruding from the center hole 64 is driven to hide in the turntable 13, the camera is placed on the shell 12, the main body of the camera falls on the upper surface of the shell 12, the camera head of the camera is inserted into the center hole 64, the restriction on the lever 20 is released, and the turntable is driven to return to its original state under the action of the spring 19. The disk 13 rotates, driving the slide bar 15 and the eccentric wheel 16 to rotate and return to the initial state, driving the lever 20 to rotate in the direction of the initial state, and the volume of the eccentric wheel 16 hidden in the rotating disk 13 is moved from the center hole 64 to the center hole 64, and the rubber ring 17 on the outside of the eccentric wheel 16 is pressed against the outer wall of the camera head, thereby limiting the camera head of the camera to the center position of the center hole 64. Since the line connecting the center position of the center hole 64 and the protrusion at the lower end of the slide bar 7 is arranged vertically with the ruler 10, the camera head of the camera is limited to the center position of the center hole 64, thereby improving the measurement accuracy after the left and right cameras are adjusted.

[0052] After the turntable 13 stops rotating, the lever 20 can be pushed toward the initial position so that the rubber ring 17 on the outside of the eccentric wheel 16 is further pressed against the outer wall of the camera lens. The center hole 64 is set relatively large to accommodate cameras of different sizes. The camera is limited to the center position of the center hole 64 by the eccentric wheel 16, thereby improving the measurement accuracy after the distance between the left and right cameras is adjusted.

[0053] Embodiment 4

[0054] like Figure 1-18 As shown, the two sides of the cross frame 1 are rotatably connected with the rotating rod 4 21, the rotating rod 4 21 is rotatably connected with the slider 3 22, the slider 3 22 slides in the rotating rod 5 23, the slider 3 22 is fixedly connected with one end of the spring 24, the other end of the spring 24 is fixedly connected with the rotating rod 5 23, the two sides of the slider 3 22 are fixed with spring limiting rods 25, the spring limiting rods 25 enclose the spring 24 in the rotating rod 5 23, and the two sides of the cross frame 1 are fixed with limiting plates 65;

[0055] The rotating rod 5 23 is rotatably connected to the rotating frame 26, the rotating frame 26 is rotatably connected to the horizontal frame 1, the rotating frame 26 is rotatably connected to the screw rod 1 27, the screw rod 1 27 is threadedly connected to the slide 28, the slide 28 is slidably connected to the rotating frame 26, two sliders 4 29 are slidably connected to the slide 28, a pulley 30 is provided at the connection between the slider 4 29 and the slide 28, the slider 4 29 is internally threadedly connected to the screw rod 2 31, the lower end of the screw rod 2 31 is fixed to a pressing plate 32, and the lower end of the pressing plate 32 is provided with a rubber pad;

[0056] The working principle of the above technical solution is as follows: the rotating rod 4 21 is rotated toward the side close to the housing 12, so as to drive the rotating rod 5 23 to rotate, drive the rotating frame 26 to rotate, and then drive the front end of the rotating frame 26 to rise, drive the slide 28, the screw 2 31 and the pressure plate 32 to rise upward, and install the left and right cameras on the housing 12 respectively; the rotating rod 4 21 is rotated toward the side away from the housing 12, so as to drive the rotating rod 5 23 to rotate, drive the rotating frame 26 to rotate, drive the front end of the rotating frame 2 to press down, drive the slide 28, the screw 2 31 and the pressure plate 32 to press down with the front end of the rotating frame 2, and the pressure plate 32 presses on the upper end of the camera; the rotating rod 4 21 is continued to be rotated, so as to drive the slider 3 22 to slide in the rotating rod 5 23, drive the spring 24 to be compressed, and the spring limiting rod 25 limits the spring 24 to the rotating rod 5 2 3, to prevent the middle part of the spring 24 from bending outwards. When the slider 3 22 rotates beyond the vertical state, the rotating rod 4 21 and the rotating rod 5 23 rotate rapidly, and the rotating rod 4 21 abuts against the limit plate 65. The rotating rod 4 21 and the rotating rod 5 23 form an angle in the opposite direction and cannot rotate. At this time, under the tension of the spring 24, the front end of the rotating frame 26 is always kept in a downward pressing state, thereby fixing the camera between the housing 12 and the pressure plate 32. The lower end of the pressure plate 32 is provided with a rubber pad, and the rubber pads are in contact with the upper surface of the camera to prevent the camera from being crushed. The screw 2 31 can be rotated, and the screw 2 31 and the slider 4 29 are threadedly rotated, driving the screw 2 31 and the pressure plate 32 to move downward, further pressing the camera between the housing 12 and the pressure plate 32.

[0057] Since the positions of buttons and harnesses on the top of different cameras are inconsistent, before the camera is placed on the housing 12 and the pressing plate 32 is pressed against the camera, the pressing position of the pressing plate 32 can be set, and the screw rod 27 is rotated, and the screw rod 27 and the slide 28 are threadedly rotated, driving the slide 28 to slide on the rotating frame 26, thereby changing the longitudinal position of the pressing plate 32, and then changing the longitudinal position of the pressing plate 32 pressing on the top of the camera. The slider 29 can move horizontally left and right on the slide 28, thereby changing the horizontal position of the pressing plate 32, and then changing the horizontal position of the pressing plate 32 pressing on the top of the camera, and thus can be set for different cameras;

[0058] After the camera is fixed directly between the housing 12 and the pressure plate 32, when it is necessary to adjust the distance between the left and right cameras, that is, to change the distance between the slider 17 and the slider 29, and change the distance between the two housings 12, the two sliders 4 29 follow and slide on the slide 28, and a pulley 30 is provided on the contact surface between the slider 4 29 and the slide 28 to reduce the friction between the slider 4 29 and the slide 28, so as to facilitate the pressure plate 32 to be pressed against the upper end of the camera, and the slider 4 29, the pulley 30, the screw 2 31 and the pressure plate 32 as a whole can move together with the housing 12 on which the camera is placed.

[0062] The working principle of the above technical solution is: start motor 2 37 to drive gear 36 to rotate, drive gear 36 and arc frame 34 to engage in gear transmission, drive arc frame 34 to slide in support frame 1 35, drive connecting member 33 to rotate with arc frame 34, drive horizontal frame 1 to move, drive binocular camera to move, because the center of arc frame 34 coincides with the image collection object, so after the binocular camera changes its angle, the camera head of the binocular camera always remains aligned with the image collection object, thereby increasing multi-angle image collection, start motor 39, drive support frame 1 35 to rotate, drive arc frame 34 to rotate, and then drive the angle of binocular camera, thereby further increasing multi-angle image collection.

The long rod 2 53 is fixed to one end of the support plate 1 55, and the other end of the support plate 1 55 is hingedly connected to the support plate 2 56, and the support plate 2 56 is hingedly connected to the connecting rod 3 57. The end of the connecting rod 3 57 is rotated at the connection between the connecting rod 2 47 and the rotating plate 48, and the connecting rod 3 57 is rotatably connected to the long rod 3 58;

[0066] The cleaning component also includes a cleaning cloth 59, one end of the cleaning cloth 59 is fixed on a cloth roll 1 61, and the other end of the cleaning cloth 59 is passed through the support plate 2 56, the support plate 1 55 and the long rod 3 58 in sequence, and is fixed on the cloth roll 2 62, the cloth roll 1 61 and the cloth roll 2 62 are both rotated on the connecting frame 60, the connecting frame 60 is fixedly connected to the connecting rod 3 57, the end of the cloth roll 1 61 is connected to the output end of the motor 4 63, and the motor 4 63 is fixed on the connecting frame 60;

[0067] The working principle of the above technical solution: Since the binocular camera is used in multiple scenes, dust often falls on the camera head of the binocular camera, which affects the effect of image acquisition. Two cleaning components are set in the device to clean the two cameras;

[0068] In the initial state, the cleaning cloth 59 is located near the end of the cylinder 41, so that the cleaning cloth 59 cannot block the image acquisition line of sight of the camera head. When dust appears on the camera head, the cylinder 41 is started to drive the telescopic rod 42 to extend, drive the long rod 1 43 to move forward, and the long rod 1 43 slides forward in the U-shaped frame 44, driving the connecting rod 1 46 to move, driving the connecting rod 2 47 to rotate, driving the rotating plate 48 to rotate, driving the center rod 51 and the foam layer 52 to rotate, and the foam layer 52 rests on the cleaning cloth 59. After the telescopic rod 42 continues to move forward and rests on the inner slide 45, it pushes the inner slide 45, and the inner slide 45 slides with the outer shell 2 40. The inner slide 45 moves forward, and the cleaning cloth 59 on the support plate 1 55 contacts the lower edge of the camera head, squeezing the support plate 1 55 to move around the long rod 2 53 as the axis.

When the cleaning cloth 59 on the supporting plate 2 56 has been used for a preset number of times, the motor 4 63 is started to drive the cloth roll 1 61 to rotate, and a part of the cleaning cloth 59 is rolled up by the cloth roll 1 61, driving the cloth roll 2 62 to unwind, and the cleaning cloth 59 on the supporting plate 2 56 is replaced by a clean part, so as to more effectively remove the dust on the camera head;

[0069] A chamber is provided inside the rotating plate 48. By removing the plug 50, cleaning liquid can be injected into the chamber. In the initial state, the rotating plate 48 tilts downward, and the cleaning liquid in the chamber drips onto the foam layer 52 through the small hole 49. When there are stubborn stains on the camera, the cylinder 41 controls the telescopic rod 42 to extend, so that the foam layer 52 soaked with cleaning liquid is against the cleaning cloth 59, and the motor 4 63 is started to drive the cloth roll 1 61 to rotate, and drive the cleaning cloth 59 to move. As the cleaning cloth 59 moves, the foam layer 52 applies the cleaning liquid to the cleaning cloth 59 until the support The cleaning cloth 59 on the second plate 56 is soaked with cleaning liquid. The cleaning cloth 59 with cleaning liquid can wipe the camera more thoroughly. When the cylinder 41 controls the telescopic rod 42 to be in a retracted state, the rotating plate 48 tilts downward, and the foam layer 52 does not contact the cleaning cloth 59. The motor 4 63 is started to drive the cloth roll 1 61 to rotate, and drive the cleaning cloth 59 to move. The cleaning cloth 59 cannot be soaked in the cleaning liquid. The cleaning cloth 59 is in a dry and clean state, and the camera wiped with the cleaning liquid can be further wiped dry, thereby removing stubborn stains and wiping the camera dry.

[0070] The cylinder 41 is used in conjunction with the motor 4 63 to control the cleaning cloth 59 to remain in a dry state or a state soaked in cleaning liquid or a state in which the two are set at an interval to cope with cameras with different degrees of contamination.
