Description

Technical Field

[0001] This application relates to the technical field of scanning devices, and more particularly to an upper limb measuring instrument that acquires images from multiple camera groups. Background Technology

[0002] Multi-camera image acquisition upper limb measuring instruments are devices that use cameras to capture information about the surface of the arm to determine whether edema has occurred. In existing multi-camera image acquisition upper limb measuring instruments, the hand support and arm support are relatively fixed, which makes it impossible to fully match the detection of different arm lengths. Moreover, the image information acquired by the camera is incomplete, making it impossible to accurately determine whether edema has occurred. Utility Model Content

[0003] The purpose of this application is to provide a multi-camera image acquisition upper limb measuring instrument, which can adapt to the scanning of arms of different lengths by adjusting the distance between the hand support component and the arm support component, and is equipped with at least two image acquisition components to obtain complete image information of the arm, thereby improving the judgment accuracy.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, a multi-camera image acquisition upper limb measuring instrument is provided, including: a base plate, an arm support assembly, a hand support assembly, and at least two image acquisition components; the arm support assembly and the hand support assembly are installed on the base plate at intervals along a first direction, and the distance between the hand support assembly and the arm support assembly is adjustable; the two image acquisition components are disposed at intervals on the base plate, and are both located in the area between the arm support assembly and the hand support assembly;

[0006] The image acquisition component includes a mounting frame and multiple cameras. The mounting frame is in a closed loop shape and has a through hole that allows an arm to pass through. The multiple cameras are spaced apart on the inner wall of the through hole.

[0007] Furthermore, the hand support assembly is slidably mounted on the base plate and can move relative to or away from the arm support assembly along the first direction.

[0008] Furthermore, the hand support assembly includes a hand support bracket, a slider, and a hand support component. The slider is installed at the bottom of the hand support bracket, the hand support component is installed at the top of the hand support bracket, and the base plate is provided with a guide rail that slides in cooperation with the slider.

[0009] Furthermore, the hand support bracket includes two vertically arranged support parts and a connecting part integrally formed on the top of the two support parts. The bottom of each of the two support parts is provided with a slider, and the hand support is located at the center of the connecting part.

[0010] Furthermore, a hand support position is formed on the top of the hand support member, and the distance between the hand support position and the hand support bracket is adjustable.

[0011] Furthermore, the hand support includes a first fixed part fixed to the hand support bracket, a first movable part telescopically mounted on the first fixed part, and a hand support part mounted on the top of the first movable part, wherein the hand support position is formed on the hand support part.

[0012] Furthermore, the top of the arm support assembly has an arm support position for supporting the arm, and the distance between the arm support position and the base plate is adjustable.

[0013] Furthermore, the arm support assembly includes a second fixed part fixed to the base plate, a second movable part telescopically mounted on the second fixed part, and an arm support part mounted on the top of the second movable part, wherein the arm support part has the arm support position formed thereon.

[0014] Furthermore, the top of the arm support is in a downwardly concave arc shape.

[0015] Furthermore, the through hole is octagonal in shape, and each side extends along the first direction to form a corresponding scanning area. Four cameras are provided, and the four cameras are respectively located in the four scanning areas, and the four cameras are evenly spaced.

[0016] The beneficial effects of this application are as follows: The measuring instrument mainly consists of a base plate, an arm support assembly, a hand support assembly, and at least two image acquisition components. The arm support assembly and the hand support assembly are installed on the base plate at intervals along a first direction, and the distance between them can be flexibly adjusted according to the length of the arm to be measured. This design ensures that the device can be widely applied to people of different body types and ages, improving the versatility and comfort of the measurement. More importantly, the measuring instrument is equipped with at least two image acquisition components, which are spaced apart on the base plate and located in the area between the arm support assembly and the hand support assembly. Each image acquisition component adopts a closed-loop fixing frame design, with a through hole in the center of the fixing frame for the arm to easily pass through. Multiple cameras are evenly spaced on the inner wall of the through hole. These cameras can simultaneously capture images of the arm surface from different angles. Through multi-angle shooting, the measuring instrument can capture comprehensive and complete image information of the arm, avoiding the image loss problem that may exist under a single viewpoint. The acquired image information is then transmitted to the processing system, which uses image stitching, fusion, and other algorithms to generate a three-dimensional model or a two-dimensional panoramic image of the arm. Based on this detailed image data, the measuring instrument can use image analysis technology to accurately determine whether there are abnormalities such as edema in the arm, providing strong support for the early diagnosis and treatment of diseases. This high-precision, comprehensive detection method not only improves the accuracy of medical testing, but also enhances the user experience, making upper limb measurement more convenient, comfortable and reliable.

[0023] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figures 1-4 As shown, this embodiment provides a multi-camera image acquisition upper limb measuring instrument, including: a base plate 1, an arm support assembly 2, a hand support assembly 3, and at least two image acquisition components 4; the arm support assembly 2 and the hand support assembly 3 are installed on the base plate 1 at intervals along a first direction, and the distance between the hand support assembly 3 and the arm support assembly 2 is adjustable; the two image acquisition components 4 are spaced apart on the base plate 1, and are both located in the area between the arm support assembly 2 and the hand support assembly 3; the image acquisition component 4 includes a fixing frame 401 and a plurality of cameras 402, the fixing frame 401 is in a closed loop shape and has a through hole 403 for the arm to pass through, and the plurality of cameras 402 are spaced apart on the inner wall of the through hole 403.

[0027] Based on the above scheme, the arm support assembly 2 and the hand support assembly 3 are respectively installed on the base plate 1, and the distance between them can be adjusted according to the length of the arm to be measured. This design allows users to change the distance between the hand support assembly 3 and the arm support assembly 2 by manually adjusting or electrically adjusting the mechanism according to their own arm length, ensuring that the arm can be placed comfortably and stably during measurement. The adjustable distance design solves the problem of poor adaptability caused by the fixed hand support and arm support in traditional multi-camera image acquisition upper limb measuring instruments, making the device suitable for people of different ages and body types, and improving the versatility and flexibility of measurement. At least two image acquisition components 4 are spaced apart on the base plate 1, located in the area between the arm support component 2 and the hand support component 3. Each image acquisition component 4 consists of a closed-loop mounting bracket 401 and multiple cameras 402. A through hole 403 is formed in the center of the mounting bracket 401 for the arm to pass through, and the cameras 402 are evenly spaced on the inner wall of the through hole 403. When the arm is placed between the arm support component 2 and the hand support component 3, the multiple cameras 402 simultaneously capture images of the arm surface from different angles. This multi-angle shooting method ensures the comprehensiveness and integrity of the arm images, avoiding the problem of missing image information caused by the limited field of view of a single camera 402. The acquired image information is transmitted to a processing system, where algorithms such as image stitching and fusion are used to generate a 3D model or a 2D panoramic image of the arm. Subsequently, image analysis technology is used to detect abnormalities such as edema on the arm surface, improving the accuracy and precision of the assessment. Overall, employing at least two image acquisition components 4 and multiple cameras 402 for multi-angle imaging ensures the comprehensiveness and integrity of arm images. This design effectively avoids the image information loss problem caused by the limited field of view of a single camera 402, improving the quality and accuracy of image acquisition. Based on comprehensive and complete image information, and through advanced image analysis and processing technology, the multi-camera image acquisition upper limb measuring instrument of this application can more accurately determine whether there are abnormalities such as edema in the arm. This high-precision judgment is of great significance for the early diagnosis and treatment of diseases.

[0028] Furthermore, the hand support assembly 3 is slidably mounted on the base plate 1 and can move relative to or away from the arm support assembly 2 along the first direction. The innovative design of slidingly mounting the hand support assembly 3 on the base plate 1 allows it to move freely along the first direction. Users can easily adjust the position of the hand support assembly 3 according to the actual length of the arm to be measured, moving it relative to or away from the arm support assembly 2 to achieve the best fit. This sliding mounting method not only simplifies the adjustment process and improves adjustment efficiency but also ensures that the distance between the hand support assembly 3 and the arm support assembly 2 can accurately match arms of different lengths. Whether it's a child's small arm or an adult's longer arm, a simple sliding adjustment can find the most suitable placement position, thus ensuring measurement accuracy and comfort.

[0029] Furthermore, the sliding hand support assembly 3 enhances the stability and durability of the equipment. Thanks to the sliding mechanism, the hand support assembly 3 remains stable during movement, preventing wobbling or tilting caused by improper adjustment. At the same time, the sliding mechanism's design also considers wear and maintenance issues under long-term use, ensuring the long-term stable operation of the equipment.

[0030] Specifically, the hand support assembly 3 includes a hand support bracket 301, a slider 302, and a hand support component 303. The slider 302 is installed at the bottom of the hand support bracket 301, and the hand support component 303 is installed at the top of the hand support bracket 301. A guide rail 5 is provided on the base plate 1 to slide smoothly along the slider 302. The hand support bracket 301 serves as the supporting structure for the entire assembly, responsible for bearing and fixing other components. The slider 302 is installed at the bottom of the hand support bracket 301, and it matches the pre-set guide rail 5 on the base plate 1, allowing the hand support assembly 3 to slide smoothly and stably along the guide rail 5. The guide rail 5 is firmly fixed to the base plate 1, and its shape and size are precisely calculated to ensure that the slider 302 can move smoothly within it, while preventing the hand support assembly 3 from shifting or shaking during sliding. This design not only improves the adjustment accuracy of the hand support assembly 3 but also enhances the overall stability of the device. The hand support 303 is mounted on top of the hand support bracket 301, directly contacting the user's wrist or palm. The hand support 303 is designed for comfort and support, using ergonomic materials and shapes to reduce user fatigue during measurement. Furthermore, the hand support 303 can be replaced or adjusted as needed to suit different users' individual requirements. Through the cooperation of the slider 302 and the guide rail 5, the user can easily slide the hand support assembly 3 to a suitable position along the first direction according to the length of the arm to be measured. Whether it is closer to or further away from the arm support assembly 2, precise adjustment can be achieved, ensuring the arm is in optimal condition during measurement. This design not only improves measurement accuracy but also enhances user convenience, making upper limb measurement simpler and more efficient.

[0031] Furthermore, the hand support bracket 301 includes two vertically arranged support parts and a connecting part integrally formed at the top of the two support parts. Each of the two support parts has a slider 302 at its bottom, and the hand support component 303 is located at the center of the connecting part. The two vertically arranged support parts, as the main body of the hand support bracket 301, each have a slider 302 installed at their bottom. The two sliders 302 are tightly fitted with two pre-set guide rails 5 on the base plate 1, realizing the sliding adjustment function of the hand support component 3. Simultaneously, the vertical design of the support parts helps maintain the balance and stability of the hand support component 3 during sliding, avoiding wobbling or tilting. The connecting part is located at the top of the two support parts and is tightly connected to them in an integral manner. This connection method not only enhances the overall strength of the hand support bracket 301 but also simplifies the manufacturing process and reduces costs. The hand support component 303 is located at the center of the connecting part for direct contact with the user's arm. The design of the hand support component 303 fully considers comfort and support, and is made of soft, breathable material to reduce user discomfort during measurement.

[0032] To further enhance the adaptability and comfort of the multi-camera image acquisition upper limb measuring instrument, the hand support assembly 3 in this application is designed with an adjustable-spacing hand support position. Specifically, the top of the hand support 303 forms a hand support position specifically designed to support the user's wrist or palm. This hand support position is designed with full consideration of ergonomic principles, aiming to provide the user with optimal support and comfort. More importantly, the spacing between the hand support position and the hand support bracket 301 is adjustable. This means that users can fine-tune the height or position of the hand support position according to their arm thickness and comfort needs. This design allows the multi-camera image acquisition upper limb measuring instrument to more accurately adapt to the arm characteristics of different users, improving measurement accuracy and user satisfaction. To achieve the adjustable spacing, some form of adjustment mechanism, such as threaded adjustment or snap locking, may be used between the hand support 303 and the hand support bracket 301. These adjustment mechanisms allow users to easily adjust the position of the hand support position without disassembling the hand support assembly 3 to meet personalized needs.

[0033] Specifically, the hand support 303 includes a first fixed part 3031 fixed to the hand support bracket 301, a first movable part 3032 telescopically mounted on the first fixed part 3031, and a hand support part 3033 mounted on the top of the first movable part 3032, with the hand support position formed on the hand support part 3033. The first fixed part 3031 is firmly fixed to the hand support bracket 301, serving as the supporting foundation for the entire hand support 303, and can be secured by bolts, welding, or other fastening methods to ensure a stable connection with the hand support bracket 301. The first movable part 3032 is telescopically mounted on the first fixed part 3031. This telescopic design allows the hand support part 3033 to move up and down relative to the hand support bracket 301, thereby adjusting the distance between the hand support position and the hand support bracket 301. Users can easily adjust the telescopic length of the first movable part 3032 according to their arm length and comfort needs, thereby changing the height of the hand support position. The hand support 3033 is mounted at the top of the first movable part 3032 and is the part that the user's arm directly contacts. It is made of a soft, breathable material to provide comfortable support. The hand rest formed on the hand support 3033 is carefully designed in shape and size to conform to ergonomic principles, ensuring that the arm receives optimal support and stability when placed.

[0034] Similarly, to further enhance the adaptability and user experience of the multi-camera image acquisition upper limb measuring instrument, the arm support assembly 2 in this application also adopts an adjustable spacing design. The top of the arm support assembly 2 is designed with an arm support position for supporting the arm. This arm support position not only provides stable support but also ensures arm comfort during the measurement process. More importantly, the spacing between the arm support position and the base plate 1 is adjustable. This design allows the arm support position to adjust its height synchronously with the hand support position, ensuring that the arm remains horizontal regardless of the height of the hand support position. This synchronous adjustment mechanism greatly improves the flexibility and adaptability of the multi-camera image acquisition upper limb measuring instrument, enabling the device to better meet the personalized needs of different users.

[0035] To achieve adjustable spacing between the armrest and the base plate 1, the armrest assembly 2 adopts a structural design similar to that of the handrest 303. Specifically, the armrest assembly 2 includes a second fixed part 201 fixed to the base plate 1, a second movable part 202 telescopically mounted on the second fixed part 201, and an armrest part 203 mounted on the top of the second movable part 202. The second fixed part 201 serves as the supporting foundation for the entire armrest assembly 2, firmly fixed to the base plate 1. The second movable part 202 is connected to the second fixed part 201 via a telescopic mechanism, allowing the armrest part 203 to move up and down relative to the base plate 1. Users can adjust the telescopic length of the second movable part 202 by operating the telescopic mechanism, thereby changing the height of the armrest. The armrest formed on the armrest part 203 is also carefully designed in shape and size to conform to ergonomic principles, and is made of soft, breathable material to provide comfortable support. At the same time, the shape of the armrest also takes into account the natural bending and placement habits of the arm, ensuring that the arm can receive the best support and stability when placed.

[0036] Specifically, the top of the arm support 203 is a downwardly concave arc shape. The downwardly concave arc shape can closely conform to the natural curve of the human arm. Especially when the arm is placed on the arm support, this arc shape design can provide more stable and comfortable support. Compared with traditional flat or straight designs, the arc shape design can more effectively distribute the weight of the arm and reduce local pressure on the arm, thereby avoiding discomfort caused by long-term measurement.

[0037] Furthermore, the arc-shaped design helps maintain the stability of the arm during measurement. When the arm naturally rests against the arc-shaped arm rest, its position and posture are relatively fixed, making it less prone to wobbling or shifting. This not only improves the accuracy of the measurement but also reduces errors that may occur due to arm movement.

[0038] Preferably, the through-hole 403 is octagonal, with each side extending along the first direction to form a corresponding scanning area. Four cameras 402 are provided, each corresponding to one of the four scanning areas, and the four cameras 402 are evenly spaced. The octagonal through-hole 403 design has several advantages. First, the octagonal structure is more complex than traditional circles or squares, better adapting to the complex shape of the upper limb and ensuring that more details and angles are covered during scanning. Second, each side of the octagon extends along the first direction, forming an independent scanning area. This design allows each scanning area to focus on a specific part of the upper limb, improving scanning accuracy and efficiency. Regarding the camera 402 layout, this solution uses four cameras 402 respectively positioned in the four scanning areas. These four cameras 402 are evenly spaced, ensuring comprehensive scanning while avoiding mutual interference between the cameras 402. Each camera 402 focuses on its corresponding scanning area, accurately capturing image information within that area to achieve detailed scanning of the upper limb.

[0039] Furthermore, this camera 402 layout offers a degree of flexibility. Depending on actual needs, the scanning effect can be further optimized by adjusting the parameters of the cameras 402 or by adding additional cameras 402. For example, parameters such as the focal length and exposure of the cameras 402 can be adjusted to adapt to different lighting conditions or the requirements of the scanned object; additional cameras 402 can also be added to the other sides of the octagonal through-hole 403 to achieve simultaneous scanning of more parts of the upper limb.
