Problems solved by technology

However, the fusion-based synthesis method has the following disadvantages: 1) This method cannot reversely calculate the weighting coefficient according to the characteristics required by the user, that is, there is only a mapping relationship between the weighting coefficient and the feature, but there is no inverse mapping between the feature and the weighting coefficient
Although this method can synthesize motion according to the user's requirements, it cannot achieve high-level control over motion style and motion type.

Embodiment Construction

[0022] The present invention proposes a method for synthesizing motion of a virtual character using motion capture data based on function-based statistical analysis. Function-based statistical analysis is a statistical analysis method for time series. This method uses function-based statistical analysis to extract the index that best describes its internal change law from a given time series sample, thereby obtaining a low-dimensional function subspace. Each dimension of this space is a function, which the present invention calls "characteristic motion". The number of characteristic functions needs to be determined according to the actual problem. A certain criterion can be the error between the projection and reconstruction result of the motion data sequence and the sequence itself. This set of "feature motions" is orthogonal, and in the subspace based on the "feature motions", any motion data sequence can be projected to the "feature motions" to obtain a set of coordinate c...

Abstract

This method includes steps of: (1) obtaining movement data specimen; (2) statistically analyzing the obtained reduction specimen movement data series (MDS) on the basis of functions to obtain the character movement; (3) depending on the user's control or application requirement to combine a new MDS; (4) after-processing the combined MDS. This method possesses a good currency, suits the application in games and the virtual realism roam to generate or control the interacting behavior of virtual roles. It also suits to form fast and vividly numerous virtual roles in moving picture edition and movie/ video production.

Description

technical field [0001] The present invention relates to a method for synthesizing motion of a virtual character, in particular to a method for synthesizing motion of a character based on motion capture data. Background technique [0002] In recent years, the application of virtual reality technology has appeared in more and more fields. From online games to film and television production, from sports training to safety rehearsals, virtual reality technology can be seen. Among these applications, virtual characters, as the representation of characters in the computer, are one of the key elements to improve their realism and interactivity. However, how to model the motion of virtual characters and then synthesize realistic and constrained virtual character motions is a challenging topic. [0003] Most traditional virtual character animations are manually edited and generated by experienced animators using software tools. Due to the high degree of freedom of the characters, ...
