Figures 1-5As shown, the embodiment provides a single group of camera image acquisition upper limb measuring instrument, comprising: base 1, arm support assembly 2, hand support assembly 3, scanning assembly 4 and driving assembly 5, the arm support assembly 2 and the hand support assembly 3 are installed on the base 1 along the first direction, and the spacing between the hand support assembly 3 and the arm support assembly 2 is adjustable, the scanning assembly 4 is slidingly installed on the base 1, and can linearly slide in the area between the arm support assembly 2 and the hand support assembly 3, the driving end of the driving assembly 5 is connected with the scanning assembly 4; the scanning assembly 4 comprises a plurality of cameras 402 and a fixed frame 401, the fixed frame 401 is in the form of a closed loop, and a through hole is formed for the arm to pass through, and a plurality of cameras 402 are arranged on the inner wall of the through hole.

[0028] Based on the above scheme, the arm support assembly 2 is used to support the arm, the hand support assembly 3 is used to support the wrist or palm, the arm support assembly 2 and the hand support assembly 3 are respectively installed on the base 1, and the distance between the two can be adjusted as needed, and the distance between the hand support assembly 3 and the arm support assembly 2 is flexibly adjusted to ensure that the arm is completely placed between the two, and this design allows the device to adapt to arms of different lengths, ensuring that the arm can be placed comfortably and stably during scanning. The scanning assembly 4 is designed to be able to slide linearly on the base 1, covering the entire area from the arm support assembly 2 to the hand support assembly 3, ensuring that the scanning assembly 4 can perform complete scanning along the arm regardless of the length of the arm. The driving assembly 5 is connected with the scanning assembly 4 to provide power for the sliding of the scanning assembly 4, and by controlling the driving assembly 5, the movement speed and position of the scanning assembly 4 can be accurately controlled to realize an accurate scanning process. The core of the scanning assembly 4 is the fixed frame 401 and multiple cameras 402, the fixed frame 401 is in the shape of a closed loop, and a through hole is formed in the middle for the arm to pass through, this design not only ensures the stability of the scanning, but also avoids the direct contact between the camera 402 and the arm. The cameras 402 are arranged at intervals on the inner wall of the through hole, ensuring that the arm is photographed from multiple angles, and the cooperative work of the multiple cameras 402 can capture detailed image information of the surface of the arm, including skin texture, color change, etc., providing rich data support for subsequent edema judgment. In summary, by adjusting the distance between the hand support assembly 3 and the arm support assembly 2, the device can adapt to arms of different lengths, improving the flexibility and universality of use; the movable scanning assembly 4 combined with the multi-camera 402 system can scan the arm from all directions without dead angles, ensuring that the obtained arm image information is complete and accurate, which helps to improve the accuracy and reliability of subsequent edema judgment; moreover, the comfort of the measured person is considered, and by adjusting the distance and providing stable support, the discomfort during the scanning process is reduced. At the same time, the automatic scanning process also reduces the workload of medical staff. In addition, complete and accurate arm image information provides doctors with more diagnostic basis, which helps to more accurately judge the edema situation and its severity, so as to develop a more scientific and reasonable treatment plan.

[0029] In some embodiments, the scanning assembly 4 comprises two first sliding blocks 403 arranged at the bottom of the fixed frame 401, and a connecting piece 404 arranged on the fixed frame 401, the connecting piece 404 being connected with the driving end of the driving assembly 5, and the base 1 is provided with a first guide rail 6 matched with the first sliding block 403 for sliding. The two first sliding blocks 403 are stably mounted at the bottom of the fixed frame 401, ensuring the stability and smoothness of the scanning assembly 4 during movement. Meanwhile, the first guide rail 6 matched with the first sliding block 403 is arranged on the base 1, so that the scanning assembly 4 can accurately slide in a straight line along the preset path in the area between the arm support assembly 2 and the hand support assembly 3. Through the close cooperation of the first sliding block 403 and the first guide rail 6, the movement track of the scanning assembly 4 is effectively controlled, further improving the accuracy and reliability of the scanning. The connecting piece 404 serves as a bridge between the scanning assembly 4 and the driving assembly 5, one end of which is firmly connected to the fixed frame 401 of the scanning assembly 4, and the other end is connected with the driving end of the driving assembly 5. When the driving assembly 5 is started, the scanning assembly 4 can move at a predetermined speed and direction through the power transmitted by the connecting piece 404, realizing the full-range scanning of the arm.

[0030] Further, the driving assembly 5 comprises a support 501, a motor 502, a driving shaft 503, a transmission member 504 and an elastic coupling 505, the support 501 is installed on the base 1, the motor 502 is installed on the support 501, the power end of the motor 502 is connected with the driving shaft 503, the driving shaft 503 is connected with the transmission member 504, the transmission member 504 is connected with the connecting piece 404, and the elastic coupling 505 is installed between the motor 502 and the driving shaft 503. In this scheme, the support 501 serves as the support structure of the whole driving assembly 5 and is stably installed on the base 1, thereby ensuring the stability of the driving assembly 5 during the working process; the motor 502 serves as the power source and is installed on the support 501, and the power end thereof is closely connected with the driving shaft 503, so that the power generated by the motor 502 is directly transmitted to the driving shaft 503 when the motor 502 is started, thereby driving the whole transmission system to start working. The transmission member 504 is responsible for converting the rotary motion on the driving shaft 503 into the linear motion required by the scanning assembly 4, and in order to ensure the smooth progress of this conversion process, the transmission member 504 is designed to closely cooperate with the connecting piece 404, and the power is transmitted to the scanning assembly 4 through the precise mechanical structure, so that the scanning assembly 4 can move along the preset path. In particular, in order to reduce the vibration and impact between the motor 502 and the driving shaft 503 and improve the stability and reliability of the transmission, the elastic coupling 505 is installed between the motor 502 and the driving shaft 503, the elastic coupling 505 has certain elasticity and damping characteristics and can absorb and slow down the vibration and impact generated when the motor 502 operates to a certain extent, thereby protecting the driving shaft 503 and the transmission member 504 from being damaged.

[0031] Further, the transmission member 504 includes two bases 5041 spaced apart along the first direction, rotating wheels 5043 arranged on the bases 5041, and a transmission belt 5042 connected between the two rotating wheels 5043, one of the rotating wheels 5043 is connected with the driving shaft 503, and the transmission belt 5042 is compressed between the connecting member 404 and the fixed frame 401. The two bases 5041 are stably mounted on the base 1, providing a solid support for the rotating wheels 5043, and the rotating wheels 5043 are mounted on the bases 5041 and can freely rotate around their axes, one of the rotating wheels 5043 is directly connected with the driving shaft 503, when the motor 502 is started, the driving shaft 503 drives the rotating wheel 5043 to rotate, and then transmits the power of the motor 502 to the transmission system. The transmission belt 5042, as a key component connecting the two rotating wheels 5043, is compressed between the connecting member 404 and the fixed frame 401, and this compression design ensures that the transmission belt 5042 can maintain a stable tensioning state during power transmission, avoiding the decline of transmission efficiency caused by looseness or slipping. At the same time, the transmission belt 5042 also has a certain elasticity, which can absorb and slow down the vibration and impact in the transmission process to a certain extent, protecting the transmission member 504 and the scanning assembly 4 from damage. When the driving shaft 503 drives one rotating wheel 5043 to rotate, the transmission belt 5042 rotates accordingly, and then drives the other rotating wheel 5043 to rotate, because the transmission belt 5042 is compressed between the connecting member 404 and the fixed frame 401, so with the movement of the transmission belt 5042, the connecting member 404 will also move linearly along the first direction accordingly. In this way, it realizes the conversion of the rotating motion of the motor 502 into the linear motion of the scanning assembly 4, so as to drive the scanning assembly 4 to perform scanning work on the base 1.

[0032] Preferably, the hand support assembly 3 comprises a hand support bracket 301, two second sliding blocks 302 installed at the bottom of the hand support bracket 301, and a hand support piece 303 installed at the top of the hand support bracket 301, the hand support piece 303 is formed with a hand support position for supporting the wrist or palm, and the base 1 is provided with a second guide rail 7 matched with the second sliding blocks 302 for sliding. The hand support bracket 301 serves as the support structure of the entire hand support assembly 3, which is designed to be stable and reliable, capable of bearing the weight of the arm and keeping stable, the bottom of the hand support bracket 301 is installed with two second sliding blocks 302, which are matched with the second guide rail 7 provided on the base 1, so that the hand support assembly 3 can slide along a specific direction on the base 1. The hand support piece 303 is installed at the top of the hand support bracket 301, which is designed in consideration of the principle of ergonomics, aiming to provide more comfortable and stable support for the user, and the hand support piece 303 is specially formed with a hand support position for supporting the wrist or palm, which makes the subject be able to naturally place the arm on the hand support piece 303 during the scanning process, reducing the fatigue and discomfort of the arm. Through the cooperation of the second sliding blocks 302 and the second guide rail 7, the hand support assembly 3 can easily slide along the base 1, thereby adjusting the distance between the hand support assembly 3 and the arm support assembly 2, and this adjustable distance design makes the single-camera image acquisition upper limb measuring instrument adapt to arms of different lengths, improving the adaptability and flexibility of the device. At the same time, since the sliding connection between the hand support assembly 3 and the base 1 adopts a precise mechanical structure, it can ensure the stability and smoothness of the hand support assembly 3 during the adjustment of the distance.

[0033] In addition, the hand rest 303 includes a first fixed part 3031 fixed to the hand rest support 301, a first movable part 3032 telescopically installed on the first fixed part 3031, and a hand rest part 3033 installed at the top end of the first movable part 3032, and the hand rest part 3033 forms the hand rest position. The first fixed part 3031 is firmly installed on the hand rest support 301, providing a stable support foundation for the entire hand rest 303, and the first movable part 3032 is connected to the first fixed part 3031 in a telescopic manner. This design allows the first movable part 3032 to be adjusted up and down within a certain range to accommodate the arms of subjects of different heights. The hand rest part 3033 is installed at the top end of the first movable part 3032 and is directly in contact with the arm. The hand rest part 3033 is shaped according to the ergonomic principle, perfectly fitting the curve of the wrist or palm, providing comfortable support for the subject. At the same time, the hand rest position also has a certain elasticity and air permeability, which can reduce the feeling of oppression and stuffiness of the arm during long-term scanning. By adjusting the telescopic position of the first movable part 3032, the user can easily adjust the hand rest part 3033 to the most suitable position for their arm. This personalized adjustment not only improves the comfort during scanning, but also ensures the accuracy of the scanning results. Because when the arm is stably and comfortably supported, the subject is more likely to remain in a relaxed state, thereby reducing scanning errors caused by arm shaking or tension.

[0034] At the same time, the arm rest assembly 2 includes a second fixed part 201 fixed to the base 1, a second movable part 202 telescopically installed on the second fixed part 201, and an arm rest part 203 installed at the top end of the second movable part 202, and the arm rest part 203 forms an arm rest position for supporting the arm. The arm rest assembly 2 mainly consists of three parts: the second fixed part 201, the second movable part 202, and the arm rest part 203. The second fixed part 201 is installed on the base 1, providing a solid support foundation for the entire arm rest assembly 2. The second movable part 202 is connected to the second fixed part 201 in a telescopic manner. This design allows the second movable part 202 to be adjusted up and down within a certain range, and the height adjustment is adapted to the hand rest assembly 3 to accommodate arms and palms placed at different heights.

[0035] To provide a more conforming and comfortable support, the top of the arm rest portion 203 is designed as a downwardly concave arc shape. When the arm is placed on a flat surface, as the arm itself has a certain arc, maintaining such a posture for a long time can cause the arm to feel uncomfortable or tired, and by designing the top of the arm rest portion 203 as a downwardly concave arc shape, the natural curvature of the arm can be better fitted, reducing the gap between the arm and the supporting surface, thereby providing more stable and comfortable support. In addition, the downwardly concave arc shape design also helps to distribute the weight of the arm, reducing the concentrated pressure on a certain part of the arm, and this effect of dispersing the pressure helps to reduce the feeling of fatigue of the arm during a long scanning process, improving the comfort of the user.

[0036] It is worth mentioning that the through hole is octagonal in shape, and each side extends along the first direction to form a corresponding scanning area. The camera 402 is provided with four, and the four cameras 402 are respectively arranged in the four scanning areas, and the four cameras 402 are uniformly spaced. The through hole with an octagonal shape has multiple advantages. First, the structure of the octagon is more complex than the traditional circle or square, which can better adapt to the complex morphology of the upper limb and ensure that more details and angles can be covered during scanning. Second, each side of the octagon extends along the first direction to form an independent scanning area. This design allows each scanning area to focus on a specific part of the upper limb, improving the accuracy and efficiency of scanning. In terms of camera 402 layout, the present scheme adopts a scheme in which four cameras 402 are respectively arranged in four scanning areas, and the four cameras 402 are uniformly spaced. This ensures the comprehensiveness of the scan and avoids interference between the cameras 402. Each camera 402 focuses on its corresponding scanning area and accurately captures image information in that area to achieve detailed scanning of the upper limb.

[0037] In addition, this camera 402 layout also has a certain flexibility, and according to actual needs, the scanning effect can be further optimized by adjusting the parameters of the camera 402 or adding additional cameras 402. For example, the focal length, exposure, and other parameters of the camera 402 can be adjusted to adapt to different lighting conditions or the needs of the scanning object; additional cameras 402 can also be added to other sides of the octagonal through hole to achieve simultaneous scanning of more parts of the upper limb.
