Description

Technical Field

[0001] The utility model relates to the technical field of computer vision, in particular to a computer vision recognition device. Background Art

[0002] Gesture recognition in computer vision is a technology that uses mathematical algorithms to identify human gestures. It uses the camera's sensor to perform three-dimensional imaging of human hands, thereby identifying gestures.

[0003] After searching, the applicant found that a Chinese patent disclosed "a computer vision recognition device", and its publication (announcement) number is "CN218848845U". The patent mainly includes a self-service checkout machine, and a dust removal mechanism is arranged on one side of the self-service checkout machine. The dust removal mechanism includes a dust removal bracket, and one side of the dust removal bracket is fixedly connected to one side of the self-service checkout machine. The inner wall of the dust removal bracket is fixedly connected with a light rod. The computer vision recognition device, by setting the dust removal mechanism, can set a fixed time through a timer, and rotate the rotating rod after a period of time to rotate the wiping cotton to the bottom of the recognition screen. The positioning plate is driven by a motor to rotate, so that the wiping cotton can rotate to wipe the recognition screen. However, the visual recognition device is exposed to the outside for a long time, and it is easy to cause damage to the device in the standby state. For this reason, we propose a computer vision recognition device. Utility Model Content

The right side of the protective box 1 is provided with a vent 2, and the top of the protective box 1 is movably connected with a top cover 3.

[0024] In this embodiment, a forward and reverse motor 43 is fixedly connected to the bottom of the fixed plate 7;

[0025] The forward and reverse motor 43 can rotate forward and reverse. When rotating forward, the threaded rod 42 drives the threaded block 46 to rise, and vice versa.

[0026] In this embodiment, the threaded rod 42 is arranged to penetrate the fixing plate 7, and the threaded rod 42 does not contact the fixing plate 7, and the connecting block 48 is slidably connected to the rear inner wall of the protective box 1;

[0027] The fixing plate 7 will not affect the threaded rod 42 when it rotates, and the connecting block 48 is slidably connected to the rear inner wall of the protective box 1, so that the entire device has stability during movement.

[0028] In this embodiment, the top of the threaded rod 42 is fixedly connected to the limiting block 49;

[0029] The limiting block 49 is for preventing the threaded block 46 from exceeding the range.

[0030] Specifically, through the action of the forward and reverse motor 43, the driving gear 44 drives the driven gear 45 to rotate, thereby driving the threaded rod 42 to rotate. The threaded block 46 is threadedly connected to the threaded rod 42. The threaded block 46 rises and falls with the rotation of the threaded rod 42. The threaded block 46 brings the entire moving mechanism 5 up and down. In the standby state, the visual recognition device body 6 follows the threaded block 46 to descend into the protective box 1, playing a good protective role.

[0031] Example 2, please refer to the attached Figure 1 -Attached Figure 5The moving mechanism 5 includes a connecting shaft 51. Two connecting shafts 51 are provided. The two connecting shafts 51 are respectively fixed to the left and right ends of the threaded block 46. The ends of the two connecting shafts 51 away from the threaded block 46 are commonly fixedly connected to a connecting frame 52. Limiting grooves 53 are provided on the left and right sides of the connecting frame 52. A micro motor 57 is fixedly connected to the left front end of the connecting frame 52. A screw rod 55 is rotatably connected to the inner wall of one side of the left limiting groove 53. The other end of the screw rod 55 is fixedly connected to the output end of the micro motor 57. A light rod 58 is fixedly connected inside the right limiting groove 53. The circumferential surface of the light rod 58 is slidably connected to the first positioning rod 54. The circumferential surface of the screw rod 55 is threadedly connected to the second positioning rod 56. The first positioning rod 54 and the second positioning rod 56 are commonly fixedly connected to the visual recognition device body 6.

[0032] In this embodiment, the two connecting shafts 51 are respectively fixed to the left and right ends of the threaded block 46, and the ends of the two connecting shafts 51 away from the threaded block 46 are fixedly connected to a connecting frame 52;

[0033] The connecting shaft 51 enables the connecting frame 52 to move up and down following the threaded block 46 .

[0034] In this embodiment, a polished rod 58 is fixedly connected inside the right limiting groove 53, a first positioning rod 54 is slidably connected to the circumferential surface of the polished rod 58, and a second positioning rod 56 is threadedly connected to the circumferential surface of the screw rod 55;

[0035] The micro motor 57 drives the lead screw 55 to rotate, and then the second positioning rod 56 moves forward and backward, and the first positioning rod 54 slides forward and backward on the surface of the smooth rod 58.

[0036] In this embodiment, the first positioning rod 54 and the second positioning rod 56 are fixedly connected to the visual recognition device body 6;

[0037] In the standby state, under the action of the screw rod 55 , the first positioning rod 54 and the second positioning rod 56 are moved to the frontmost side, and then when the entire device is lowered, the visual recognition device body 6 does not contact the threaded rod 42 .

[0038] Specifically, when the main body 6 of the visual recognition device rises to the upper end of the protective box 1 and starts working, under the action of the micro motor 57, the screw rod 55 drives the second positioning rod 56 to move back and forth, and the first positioning rod 54 slides back and forth on the surface of the optical rod 58, so that the main body 6 of the visual recognition device can move back and forth to adjust the optimal viewing angle, facilitate image recognition, and avoid manual adjustment of the position of the protective box 1.

[0039] Working principle:

[0040] First, the driving gear 44 drives the driven gear 45 to rotate through the action of the forward and reverse motor 43, thereby driving the threaded rod 42 to rotate. The threaded block 46 is threadedly connected to the threaded rod 42. The threaded block 46 rises and falls with the rotation of the threaded rod 42, and the threaded block 46 brings the entire moving mechanism 5 up and down. When the main body 6 of the visual recognition device rises to the upper end of the protective box 1 and starts working, under the action of the micro motor 57, the screw rod 55 drives the second positioning rod 56 to move back and forth, and the first positioning rod 54 slides back and forth on the surface of the optical rod 58, so that the main body 6 of the visual recognition device can reciprocate to adjust the optimal viewing angle for easy image recognition. In the standby state, under the action of the screw rod 55, the first positioning rod 54 and the second positioning rod 56 are moved to the front side. Then, when the entire device descends, the main body 6 of the visual recognition device does not contact the threaded rod 42, and the main body 6 of the visual recognition device follows the threaded block 46 to descend into the protective box 1, which plays a good protective role and avoids damage. At this point, the entire workflow ends.
