Human skeleton modeling method

Abstract

The invention relates to a human skeleton modeling method and relates to the technical field of human skeleton modeling. The modeling method comprises steps as follows: sensors are mounted at all joints of a human body and connected with a detection host; motion capture is performed by the sensor array mounted at all the joints and data points in a video are fitted to form a spline; an edge contour curve is processed with fairing and optimization algorithms of the spline; according to a joint connector hierarchical structure of the human body, all limbs are abstracted into simple rigid geometric entities and a sample of human skeleton models is constructed with the VRML (virtual reality modeling language); the skeleton models of all the limbs can be obtained through transformation on the basis of the sample model. Analysis recognition is performed on human skeleton characteristics with a video-based motion recognition technology, the operation is simple, rapid and accurate modeling can be realized, and online analysis is realized.

Description

Technical field: [0001] The invention relates to the technical field of human skeleton modeling, in particular to a human skeleton modeling method. Background technique: [0002] In the process of human-to-human interaction, vision is the most important information, which can help people quickly obtain some key features and facts. It has a wide range of application value in the fields of intelligent video surveillance, abnormal action recognition, human-computer interaction and virtual technology. At the current stage, the current research on human action recognition mainly focuses on the structural analysis of the moving human body and the tracking of human action targets. [0003] The analysis and recognition of human actions is one of the important topics in the current research fields of computer vision and pattern recognition. Human actions are composed of continuous static poses, because the action itself has quite complex high-dimensional information in space and...

Problems solved by technology

[0004] However, the human motion information analysis system based on the traditional photography principle has the problems of complicated follow-up processing and time-consuming, and cannot be analyzed online. Moreover, the current human skeleton modeling method is relatively complicated and expensive, and cannot achieve the purpose of rapid modeling.
