Description

Technical Field

[0001] The present invention relates to the field of medical assistance technology, and in particular to a three-dimensional motion capture system for massage. Legal testing platform. Background Art

[0002] 3D motion capture, also known as 3D motion tracking or 3D motion tracking, is a technology used to accurately measure the motion of moving objects in 3D space. It is based on the principles of computer graphics. It records the motion of moving objects with tracking devices in the form of images through several video capture devices arranged in space, and then processes the image data to obtain the spatial coordinates (x, y, z) of different points of the object in different time units. Motion capture (Motion Capture or Mocap) refers more to match moving in filmmaking and games.

[0003] Existing motion capture applications include human motion recognition, aircraft posture analysis, etc. These applications filter and integrate the inertial data information we obtain, and analyze it through a series of algorithms to obtain the final result, which can be the reconstruction of human 3D motion or the analysis of aircraft or object posture. These are challenging research topics and have an important role in promoting bionic engineering, medical engineering, sports competition, game animation, etc.

[0004] Gait analysis is the main application of 3D motion capture in clinical medicine. The application of MotionAnalysis digital image capture and analysis system in gait analysis reflects the highest level of technological development. When the patient walks, the system can collect and analyze data in real time and display it in the form of 3D animation. At the same time, the MotionAnalysis system can also be synchronized with devices that output analog signals such as force plates and surface electromyography. Combined with OrthoTrak, SIMM and other software, the subject's gait, muscle length, surface electromyography, force and other data can be analyzed at the same time; and for medical motion analysis and sports medicine, 3D motion capture can provide users with accurate analysis and evaluation in many aspects (such as improving sports performance, preventing injuries, state recovery, sports equipment / rehabilitation equipment, etc.). Based on the accurate data provided by the equipment, coaches, players, team doctors, and rehabilitation therapists can more effectively formulate training plans, treatment methods and rehabilitation principles.

[0005] The method is to attach the dorsal side of the fifth metacarpophalangeal joint to the operated part, and use the active flexion and extension of the elbow joint to drive the flexion and extension of the wrist joint and the rotation of the forearm, so that the ulnar side of the lesser palm and the ulnar side of the back of the hand roll back and forth continuously on the operated part, forming a Shanghai University of Traditional Chinese Medicine The founder of the law, Ding Jifeng, once proposed the "Ding This method can dredge the meridians, clear the liver and improve eyesight, open the chest and relieve stagnation, relieve spasms and relieve pain. It is especially suitable for patients with joint damage and pain.

[0006] Current clinical teaching The demonstration of the method requires sticking marker points on the body and using a 3D motion capture camera to analyze and reflect the motion characteristics of human joints. The operation needs to be demonstrated on the testing platform, but the existing testing platforms are mostly seamless rectangular tables, so it is difficult for doctors to demonstrate the operation. When doing exercise, the mark on the back of the doctor's hand may touch the table when turning over, causing the mark to fall off, which is not conducive to normal It is also not conducive to the 3D motion capture system lens to receive the mark points attached to the body, so the traditional detection platform cannot measure the doctor's The specific process of massage cannot be demonstrated, and the only way is to put your hands on the edge of the table, which indirectly reflects the massage. The kinematic characteristics of the method make it very inconvenient to detect and use.
