Abstract

A motion capturing and analysis method based on an image technology especially relates to the motion determination technology field. The method comprises the following steps: first step, according to motion-capturing three dimensional mapping data, installing a positioning target on a human body surface; second step, establishing high-definition cameras of X, Y and Z axial directions and completely shooting a whole set of motion states; third step, segmenting high-definition image videos shot by the high-definition cameras into pictures according to a 60 shot speed; fourth step, superposing the pictures and connecting all the punctuations into a track arc. Operation is simple, a motion locus can be accurately captured, disassembling and decomposition can be performed and capturing accuracy is increased.

Description

Technical field: [0001] The invention relates to the technical field of motion measurement, in particular to a motion capture and analysis method based on image technology. Background technique: [0002] Motion capture technology involves dimension measurement, positioning and orientation determination of objects in physical space, etc., and the processed data can be directly understood by the computer. The tracker is set on the key part of the moving object, the position of the tracker is captured by the Motion capture system, and the data of the three-dimensional space coordinates are obtained after computer processing. When the data is recognized by the computer, it can be applied in animation production, gait analysis, biomechanics, ergonomics and other fields. [0003] Commonly used motion capture technologies can be divided into mechanical, acoustic, electromagnetic, active optical and passive optical in principle. Devices with different principles have their own...
