Information detection system for rotation center movement of glenohumeral joint of human shoulder

Abstract

The invention provides an information detection system for rotation center movement of a glenohumeral joint of a human shoulder and belongs to the technical field of detection. The detection system comprises a human sternum position tracking sensor, a human humerus position tracking sensor, a human scapula pose tracking sensor and a data acquisition card, wherein the human sternum position tracking sensor is used for detecting the position of human sternum and provided with four point positions for acquiring human pose information in real time; the human humerus position tracking sensor is used for detecting the position of human humerus; the human scapula pose tracking sensor is used for detecting the pose of human scapula; the data acquisition card is used for collecting the positions ofthe human sternum and the human humerus and the pose of the human scapula; the rotation center movement information of the glenohumeral joint of the shoulder in one cycle is displayed by processing based on upper computer application and data processing subprogram. According to the acquisition system, the problems of data mark point loss of a VICON detection system and blocking of a human camerasystem are solved; the acquisition system is simple, high in adaptive capacity, accurate in data acquisition and good in real-time performance, and can be applied to shoulder function bionics, shoulder function simulation, ergonomics and the like.

Description

technical field [0001] The invention belongs to the technical field of detection, in particular to a motion information detection system of the glenohumeral joint rotation center of a human body. Background technique [0002] The movement of the shoulder glenohumeral joint is the basis for the completion of various actions of the human upper limbs. Obtaining more accurate movement information of the shoulder glenohumeral joint rotation center is the basis for shoulder function bionics, shoulder function simulation, human upper limb hemiplegia recovery and bone training. The premise and basis of the effect. [0003] According to domestic and foreign literature, human joint motion information detection can be divided into electromagnetic positioning detection system, ultrasonic positioning detection system, optical positioning detection system, mechanical positioning detection system, inertial positioning detection system, etc. in terms of test types. Among them, the electrom...

Problems solved by technology

Among them, the electromagnetic positioning detection system has no line of sight occlusion limit and the receiver is miniaturized, but it is susceptible to environmental electromagnetic and metal interference; the problem of line of sight occlusion in the ultrasonic positioning detection system and optical positioning detection system is difficult to solve, for example: VICON optical detection system is easy to cause data points Lost and blocked by the human body camera system; the mechanical positioning detection system is limited by the mechanical connection, and the application space and field are greatly limited; the positioning principle of the inertial positioning system has the characteristics of isolation from the outside, but the cumulative error is very serious, and there are not many practical applications
