Embodiment Construction

[0039] A human body animation method directly driven by motion capture data based on a semantic model, comprising the steps of loading a realistic human body animation system developed based on a C++ programming language and an OpenGL graphics library into a computer and constructing and initializing a human body motion semantic model, And the generation of realistic human animation, the specific implementation of each step is as follows:

[0040] 1. Implement the method test of the present invention and carry out on the basis of one group using DVMC-8820 optical motion capture equipment or obtaining human body motion data, this group of data collects 30 groups of actions altogether, and the collector wears 32 characteristic mark points (Marker ), the sampling frequency is 60 frames per second, and each set of data contains 300 frames and takes about 5 seconds. This set of data is stored in the form of text files, and each line records the three-dimensional coordinates of the fe...

Abstract

The invention discloses a method for directly driving human animation by human motion capture data. The method is based on a semantic model, and relates to the technical fields of computer animation and human motion capture. The method comprises the following steps: the concept and the method of a human topological structure semantic model are introduced; the semantic model is taken as a connection; and on the basis of a non-uniform rational B-spline (NURBS) surface model, the method for directly driving human animation by the human motion capture data can be realized by coordinate system interpolation. An actual test shows that a retrieval method provided by the invention is able to effectively realize the driving of third dimension human animation directly by the human motion capture data, and has the advantages of good practicability and relatively high efficiency.

Description

technical field [0001] The invention relates to the technical field of computer animation, in particular to the method and field of human animation directly driven by human motion capture data. Background technique [0002] In recent years, with the rapid development of computer software and hardware technology and human motion capture technology, realistic human animation driven by motion capture data has gradually become a research and technical hotspot.
