Description

Technical Field

[0001] The utility model relates to the technical field of behavior recognition equipment, in particular to a height adjustment device for recognition equipment. Background Art

[0002] Behavior recognition is an attractive and challenging research direction in recent years. Given a cropped video, computer vision technology is used to determine the human behavior category in the video. The development of deep convolutional neural networks and the emergence of large-scale labeled data sets in recent years have significantly improved the accuracy of behavior recognition. Behavior recognition technology plays an increasingly important role in many fields such as intelligent security, human-computer interaction, video understanding, and medical health.

[0003] The utility model patent with the publication number CN 213065345 U discloses a behavior recognition camera, in which a base, a driving device, a decorative part, a mounting part and a camera are provided, wherein the driving device is installed in the base, the mounting part is installed on the driving device and extends outside the base, the camera is installed in the mounting part, the decorative part is installed outside the mounting part, and the driving device can drive the mounting part to rotate; the decorative part is arranged in an annular shape, and its cross section is arranged in an arc shape, a bayonet is arranged on the decorative part, and a clamping part is arranged on both sides of the bayonet, and the decorative part is provided with side walls extending toward the inner center direction along the two opposite outer edges of the decorative part, and the two side walls of the decorative part and the inner surface are enclosed to form a receiving groove, the mounting part is installed in the receiving groove, and the clamping part of the decorative part is clamped on the mounting part. Not only can the appearance effect of the camera be improved, but also the waterproof performance of the mounting part can be improved; it is more practical and has a strong promotion significance.

[0004] However, there are still some shortcomings in the above scheme. Although the above scheme can identify the behavior of people in the monitoring area, the behavior recognition camera in the above scheme is fixedly installed in a set area and cannot be moved. When it is necessary to identify the movement of the moving person, since the installation height of the behavior recognition camera is mostly high, the behavior recognition screen is relatively small or the screen resolution is low. At the same time, the behavior recognition screen angle is large, which affects the accuracy of the subsequent perception of the movement of the moving person. In view of this, we propose a height adjustment device for the recognition device. Utility Model Content

When the movement of the moving person needs to be identified, since the installation height of the behavior recognition camera is mostly high, the behavior recognition picture is relatively small or the picture resolution is low. At the same time, the angle of the behavior recognition picture is large, which affects the accuracy of the subsequent perception of the movement of the moving person.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] A height adjustment device for identifying equipment, such as Figure 1-Figure 4As shown, it includes a behavior recognition camera 1; a support mechanism 2 is provided on the behavior recognition camera 1, and the support mechanism 2 includes a support seat 201, the support seat 201 is connected to the bottom end of the behavior recognition camera 1, and the bottom end of the support seat 201 is rotatably connected to a bracket 202, and the inner side of the bracket 202 is rotatably connected to a driving rod 203, and the end of the driving rod 203 is rotatably connected to a driving block 204. The behavior recognition camera 1 can identify the movement state of the athlete and record the movement picture. At the same time, the recorded movement picture is processed and analyzed by intelligent AI to achieve error correction and guidance of the movement posture of the athlete, thereby improving the movement effect of the athlete. The support seat 201 structure can support the behavior recognition camera 1, and the rotatably connected bracket 20 2 can be conveniently unfolded and stored, so as to support or move the support base 201 and the behavior recognition camera 1 for transportation. The driving block 204 is respectively connected to the bracket 202 through the driving rod 203. The bracket 202 can be driven while the driving block 204 is raised and lowered, so that the bracket 202 can be adjusted between unfolding and storing. The bottom end of the bracket 202 is connected with a support foot 205. One end of the support foot 205 passes through the bracket 202 and is arranged inside the bracket 202. The bottom end of the support foot 205 is rotatably connected with a support pad 206. The support foot 205 structure can be moved and adjusted along the bracket 202, so that the support foot 205 can be moved out of the bracket 202 or moved into the bracket 202. At the same time, the support foot 205 structure can be supported after being moved out of the bracket 202. The support structure is extended, so as to conveniently adjust the support height of the support seat 201. At the same time, the support pad 206 structure can support the support foot 205, and at the same time improve the friction between the support foot 205 and the ground, thereby improving the supporting effect of the support foot 205. The rotatably connected support pad 206 can conveniently adjust the angle between the support pad 206 and the support foot 205, so that when the support foot 205 supports the support seat 201 at different angles, the support pad 206 and the ground can be kept in contact with each other, thereby avoiding the bottom tilt of the support structure caused by the angle change, thereby improving the stability of the support. The bottom end of the support seat 201 is rotatably connected to a guide rod 207, and the guide rod 207 is arranged through the drive block 204, and the drive block 204 is connected to the guide rod On the outside of 207, the guide rod 207 structure can guide the movement of the driving block 204, so that the driving block 204 moves along the guide rod 207. At the same time, a limiting structure can be set at the end of the guide rod 207 to limit the movement of the driving block 204, thereby preventing the driving block 204 from excessively moving when the bracket 202 is unfolded, causing the bracket 202 to be retracted after being fully unfolded. The guide rod 207 structure can be a screw structure. At the same time, the driving block 204 and the guide rod 207 are meshed with each other. The driving block 204 can be driven by rotating the screw. Since the driving block 204 is connected to the bracket 202 through the driving rod 203, the rotation of the driving block 204 is limited. When the guide rod 207 rotates, it can only move and adjust along the guide rod 207.At the same time, the screw structure can self-lock the drive block 204 through the thread structure, thereby preventing the drive block 204 from sliding along the guide rod 207 after the adjustment is completed, causing the support structure to loosen.

[0027] Example 2

[0028] like Figure 1 , Figure 3 As shown, a shielding mechanism 3 is provided on the support seat 201, and the shielding mechanism 3 includes a protective cover 301, which is slidably connected to the inside of the support seat 201, and one end of the protective cover 301 is set through the support seat 201. The shielding mechanism 3 can shield the behavior recognition camera 1 to prevent the behavior recognition camera 1 from being exposed to sunlight for a long time when used outdoors. The protective cover 301 structure can provide protection while shading the behavior recognition camera 1. When the athletes are exercising, the athletes approaching the behavior recognition camera 1 are prone to overturning the support structure due to accidental collision, and the protective cover 301 structure can protect the behavior recognition camera 1 when it overturns. At the same time, the protective cover 301 structure is slidably connected to the inside of the support seat 201, and the protective cover 301 can be conveniently stored when idle, thereby reducing storage space. The top of the protective cover 301 is rotatably connected to a protective plate 302, and the side of the protective plate 302 is fixedly connected to a protective cloth 303. 02 structure can protect the front end of the behavior recognition camera 1, and the protective cloth 303 on both sides can block the sunlight and reduce the interference of sunlight on the lens or the recorded picture. The inner side of the support base 201 is an arc structure, and the protective cover 301 structure corresponds to the support base 201 structure. The protective cover 301 is rotatably connected with connecting blocks 304 on both sides, and the connecting block 304 structure can drive the protective cover 301 so that the protective cover 301 can be conveniently switched between the state of being stored in the support base 201 and the state of being moved out from the support base 201 and opened. The outer side of the bracket 202 is rotatably connected with a driving ring 305, and the outer side of the driving ring 305 is rotatably connected with a connecting rod 306, and the end of the connecting rod 306 is rotatably connected to the outer side of the connecting block 304. The driving ring 305 structure can transmit the connecting block 304 and the protective cover 301 through the connecting rod 306, so that the protective cover 301 can be opened synchronously while the bracket 202 is unfolded.

[0029] When the height adjustment device of the identification device of the utility model is used, the device is moved to the sports field, and then the guide rod 207 is rotated, and the driving block 204 is moved along the guide rod 207 under the drive of the guide rod 207. When the driving rod 203 moves, the bracket 202 is driven to rotate and unfold outward through the side driving rod 203. When the bracket 202 rotates to the set angle, the rotation of the guide rod 207 is stopped, and then the support leg 205 is moved outward from the inside of the bracket 202. After the support leg 205 is adjusted to a suitable length, the bracket 202 and the support leg 205 are fixed, and the support leg 205 can support the whole through the support pad 206 at the bottom. At the same time, when the bracket 202 is rotated outward, the driving ring 305 on the bracket 202 is supported by the support pad 206 at the bottom. The connection point between the frame 202 and the support base 201 rotates in an arc trajectory with the center of the circle upward. When the driving ring 305 rotates, the driving ring 305 drives the connecting rod 306 to move upward, and the connecting rod 306 drives the connecting block 304 at the end to move upward synchronously. During the movement, the connecting block 304 rotates and opens the protective cover 301, and covers the top of the behavior recognition camera 1. At the same time, the protective cloth 303 on both sides of the protective cover 301 blocks both sides of the behavior recognition camera 1, thereby reducing the interference of sunlight on the behavior recognition camera 1. After the installation and placement are completed, the behavior recognition camera 1 can be started and the movement posture and movement data of the movement personnel in the recording area can be recorded, so as to facilitate the subsequent analysis of the movement status of the movement personnel through AI.
