DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and beneficial effects of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0031] This embodiment provides a portable image acquisition auxiliary device, as shown in the attached Figure 1 and attached Figure 2 As shown, the auxiliary device includes a bracket 1 and a fixing platform 2.

[0032] In the exemplary configuration, the bracket 1 is configured as a tripod, made of carbon fiber and aluminum alloy. It is lightweight and stable, and can be extended to a maximum height of 160 cm to accommodate various shooting scenarios. The bracket legs 11 are equipped with rubber foot pads 14, which provide a good grip and enhance stability during shooting. The top of the bracket 1 is equipped with a rotatable angle adjustment mechanism 12, preferably a ball head. The ball head is connected to a mounting base 13, which is in turn connected to a fixed platform 2.

[0033] In the exemplary structure, the fixing base 13 is composed of a fixing base locking knob 131 and a fixing base quick release plate 132 on its side. Figure 3 As shown, after installation, the fixing seat quick release plate 132 is accommodated between the baffle of the fixing seat 13 and the fixing seat locking knob 131. The fixing seat quick release plate 132 can be locked and fixed by rotating the fixing seat locking knob 131. The fixing seat quick release plate 132 is connected to the base 21 by a hand screw.

[0034] In a preferred embodiment, the fixed platform 2 consists of a base 21, a support rod 22, and a wrist fixation device 23. The support rod 22 is connected to the top of the fixed platform 2, and the wrist fixation device 23 is connected to the support rod 22. The wrist fixation device 23 includes a fixing portion for accommodating the wrist, which includes two adjustment members for fixing the wrist. The adjustment members are preferably fixed pads 232 made of silicone, and the distance between the two fixed pads 232 is adjustable.

[0035] In the exemplary structure, the fixing portion is provided with an adjusting screw 231, and the wrist fixing device 23 accurately controls the distance between the two fixing gaskets 232 through the adjusting screw 231, thereby achieving fast and effective positioning of the arm and the back of the hand, and assisting in different scenarios of image acquisition.

[0036] In a preferred embodiment, a groove 211 is provided in the center of the base 21. The groove 211 is used to place the tester's elbow. The surface of the groove 211 is made of silicone material, which can increase the tester's comfort during the shooting process. In a more preferred embodiment, the wrist fixing device 23 is connected to the support rod 22 through a fixing ring 233, and the fixing ring 233 can slide up and down along the support rod 22 to adjust the height of the wrist fixing device 23 relative to the support rod 22 to adapt to the forearm length of different test people. In a preferred embodiment, reference Figure 5 The fixing ring 233 is also provided with screws for locking and fixing with the support rod 22.

[0037] In the exemplary configuration, reference Figure 4 The support rod 22 is provided with a vertical slide rail 221 and a stopper 222 that can slide on the slide rail 221. The stopper 222 is used to limit the height of the fixed ring 233. For example, the stopper 222 is provided with a screw, which is fixed to the slide rail 221 by rotating the screw, thereby achieving precise positioning and secure locking of the wrist fixing device 23.

[0038] The working process of the image acquisition auxiliary device in this embodiment is as follows:

[0039] Pull out the tripod, adjust the support legs 11 according to the tester's height, adjust the ball head, connect the fixing base quick release plate 132 to the fixed platform base 21 with the thumb screws, and lock the fixing base quick release plate 132 to the fixing base 13 using the fixing base locking knob 131;

[0040] Then, the wrist fixing device 23 is sleeved onto the support rod 22, the testee's elbow is fixed in the groove 211, and the position of the fixing ring 233 of the wrist fixing device 23 on the support rod 22 is adjusted according to the length of the testee's arm;

[0041] Slide the stopper 222 under the fixing ring 233 and secure it by turning the screw on the stopper 222 to prevent the fixing ring 233 from sliding. Next, adjust the screw on the fixing ring 233 to secure the height-adjusted fixing ring 233 to the support rod 22. Finally, rotate the adjusting screw 231 to adjust the distance between the two fixing spacers 232, secure the subject's wrist, and begin image acquisition.

[0042] After image acquisition is completed, the wrist fixing device 23 is removed, and the supporting leg tubes 11 are rotated to retract for easy storage and carrying.

[0043] The portable image acquisition assistive device disclosed herein secures the subject's wrist with a wrist fixture, eliminating the need for the subject to adjust the position and angle of their arm during image acquisition, and eliminating the need for gripping or other arm positioning methods. Furthermore, accurate and repeatable arm positioning can be achieved by adjusting the ball head, support rod, and wrist fixture, further improving the accuracy and convenience of image acquisition.

[0044] The entire image acquisition auxiliary device can be quickly assembled and disassembled through threads and sockets, making it easy to store and carry. The overall material is made of carbon fiber, aluminum alloy, and silicone, which is lightweight and suitable for a variety of test scenarios.

[0045] During the image acquisition process, the test subject can be quickly adjusted to the optimal shooting position through the adjustment of the auxiliary device, without the need for the test subject to self-support adjustment, effectively reducing the positioning time and improving the test subject's comfort and ease of operation during the shooting process.

[0046] The embodiments described above are merely illustrative descriptions of the present disclosure and are not intended to limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements made to the technical solutions of the present disclosure by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present disclosure.
