Description

Technical Field

[0001] This utility model relates to optical three-dimensional measurement, and in particular to a three-dimensional human foot spine scanning measurement system. Background Technology

[0002] Traditional foot and spine measurement and assessment primarily rely on manual observation, physical measurement, and imaging techniques, which are inherently subjective and limited. Traditional foot measurements typically employ visual observation, footprint analysis, plaster cast taking, and simple instrumental measurement methods. Spinal assessments often utilize physical examination, X-ray measurement, moiré pattern photography, and manual palpation. These methods are not only time-consuming and labor-intensive but also lack accuracy, failing to comprehensively reflect the three-dimensional morphology and internal structure of the human body. While advancements in optical technology have led to the application of 3D scanning in anthropometrics, its high cost and complex operation have hindered widespread adoption. In recent years, some devices have attempted to combine 3D scanning with bioelectrical impedance analysis, but data fusion accuracy remains insufficient, resulting in a poor user experience. These solutions often neglect the balance between convenience and accuracy, typically only measuring the foot or spine, failing to provide a unified solution for the entire body. Furthermore, there are currently no comprehensive anthropometric measurement devices on the market that integrate foot and spine measurements.

[0003] Traditional methods typically suffer from angular errors exceeding 5° in terms of measurement accuracy, plaster cast extraction takes over 4 hours, and X-rays pose a risk of cumulative radiation exposure. Furthermore, they provide only static, single-dimensional data, and data standardization often relies on the operator's experience. Currently, the market only offers measurement equipment for specific aspects of foot or spine posture, lacking comprehensive, multi-dimensional measurement methods to fully assess human body parameters.

[0004] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0033] See Figures 1-10 As shown, one embodiment of this utility model provides a three-dimensional human foot spine scanning measurement system, including a data acquisition unit, a processing unit, and a measurement platform 16 connected in sequence;

[0034] The measuring platform 16 is used for the human body being measured to stand;

[0035] The data acquisition unit includes a first depth camera acquisition unit, a second depth camera acquisition unit, and a third depth camera acquisition unit; the first camera acquisition unit is used to acquire spinal data of the human subject being tested; the second depth camera acquisition unit acquires foot data of the human subject being tested; the third depth camera acquisition unit acquires sole data of the human subject being tested; the spinal data, the foot data, and the sole data are transmitted to the processing unit;

[0036] The processing unit is used to generate a three-dimensional model based on the spine data, the foot data, and the plantar data.

[0037] This invention collects spinal, foot, and plantar data through the auxiliary data acquisition unit of the measurement platform, achieving high-precision measurement of human body dimensions and foot data. Simultaneously, it comprehensively analyzes spinal posture and foot health data to provide a more comprehensive health assessment, offering a scientific basis for users to develop personalized health management plans and optimize exercise training programs. Furthermore, the processing unit ensures real-time processing and immediate feedback of measurement data, greatly improving measurement efficiency. The device simultaneously completes data acquisition and processing, significantly enhancing measurement accuracy. Through real-time data processing and flexible camera configuration, it achieves efficient and comprehensive scanning and data interpretation applications, avoiding the delays in data acquisition and processing inherent in traditional equipment.

[0038] In one embodiment of this utility model, a scanning frame 15 and a body measurement scanning part 14 are fixedly mounted on the measuring platform 16;

[0039] The body measurement scanning section 14 includes the first depth camera acquisition unit, which includes an upper depth camera 5 and a lower depth camera 6.

[0040] A second depth camera acquisition unit is provided inside the scanning frame 15;

[0041] The bottom of the scanning frame 15 is a transparent area, and the third depth camera acquisition unit is located in the transparent area.

[0042] In one specific embodiment, the scanning frame 15 is symmetrically arranged on the measurement platform.

[0043] like Figure 2 As shown, the measured platform includes a transparent standing area 3 and a rotating part 4;

[0044] The transparent standing area 3 is used to scan the soles of the feet of the person being tested;

[0045] The rotating part 4 is used for transporting and rotating the human body to facilitate the body measurement and scanning part 14 to collect complete human body data.

[0046] In the embodiments of this utility model, the first depth camera acquisition unit, the second depth camera acquisition unit, and the first depth camera acquisition unit each include multiple built-in depth cameras working together, with multiple shooting angles complementing each other, enhancing the comprehensiveness of data acquisition. Combined with the rotation function of the rotating part 4 and the light-transmitting design of the transparent standing area 3, it ensures that every part of the human body and the sole of the foot being measured can be scanned in detail during the acquisition process, further improving the accuracy and completeness of the measurement.

[0047] In a further embodiment, the rotating part 4 is equipped with electrode plates to acquire the electrical impedance of the human body being tested and transmit the electrical impedance to the processing unit, which can acquire the body fat percentage of the human body being tested. In another embodiment, information such as the weight of the human body being tested can be acquired simultaneously. This utility model aims to achieve rapid, accurate, and radiation-free measurement of human body parameters through optical three-dimensional scanning technology, covering multi-dimensional data such as foot, spine morphology, body fat, and weight, thereby improving measurement efficiency and accuracy.

[0048] like Figure 7 As shown, the shooting angles of the upper depth camera 5 and the lower depth camera 6 form an angle and intersect at the waist of the subject to obtain spinal data, and cover the space above the rotating part 4 to ensure that the subject standing on the rotating part can be scanned in all directions without blind spots.

[0049] In one specific embodiment, the second depth camera acquisition unit includes at least three depth cameras, such as depth camera 11, depth camera 12, and depth camera 13, to acquire data on the soles of the human feet being measured.

[0050] The third depth camera acquisition unit includes at least four depth cameras: depth camera 7, depth camera 8, depth camera 9, and depth camera 10. Each camera is positioned at a different angle to ensure comprehensive capture of foot details and improve scanning accuracy. The processing unit integrates the data from each camera using algorithms to generate a precise 3D model. The relative spatial positions and angles of all depth cameras are precisely preset and optimized using algorithms, enabling seamless data integration and fusion between cameras, thus improving the overall stability of the scanning system and the accuracy of data processing.

[0051] like Figure 8-10Depth cameras 7, 8, 9, and 10 are respectively positioned to target different areas of the foot, capturing its three-dimensional structural information. Below the transparent standing area 3, depth cameras 11, 12, and 13, through precise angular positioning, ensure detailed scanning of every corner of the sole. These depth cameras work collaboratively, with their fields of view overlapping through the specific positions and angles of each camera, thus supplementing the completeness of the foot data. In a preferred embodiment, increasing and adjusting the relative positions and angles of the cameras can improve the scanning coverage, optimize the data capture angle, and ensure the balance of multi-dimensional information acquisition, thereby further improving measurement accuracy and user experience without increasing equipment complexity. In actual implementation, the number of cameras in the first, second, and third depth camera acquisition units can be increased or decreased according to actual shooting needs, flexibly adjusting the shooting range and accuracy to accommodate users of different body types and measurement requirements.

[0052] In one embodiment of this invention, the processing unit is a microcomputer 2, which is built into the body measurement scanning unit 14. A display screen 1 is provided on the body measurement scanning unit 14 for human-computer interaction, which can be through touch interaction, voice interaction, etc. The built-in microcomputer 2 runs relevant algorithms, integrating data from various depth cameras and optimizing the scan results. The final 3D model includes detailed data on the spine and feet. Through this integrated approach, users can obtain comprehensive health analysis reports, providing strong support for personal health management and professional sports training.

[0053] Furthermore, handrails, namely handrail 17 and handrail 18, are provided on both sides of the body measurement scanning part 14 to facilitate the measurement personnel to adjust their standing posture.

[0054] In a further embodiment, multi-sensor fusion technology can be used to replace a single depth camera. Combined with dynamic capture algorithms, high-precision data acquisition and real-time processing can still be achieved, ensuring the comprehensiveness and accuracy of measurement results and meeting the needs of different users. Furthermore, a scheme using infrared thermal imaging technology combined with pressure sensors can also effectively capture human body heat distribution and plantar pressure data. Through intelligent algorithm integration, accurate measurement and comprehensive evaluation can also be achieved, further enhancing the functionality and applicability of the equipment.
