Abstract

The invention discloses a motion capture database searching method based on a dynamic bending algorithm. The method includes selecting proper motion characteristics to build a primary index and a secondary index of a motion capture database in advance, and the speed for example searching is improved. The primary index comprises motion moment attitude information. Calculation of the secondary index is based on gesture variation of skeleton motion dynamic characteristics, namely the Euclidean distance of characteristic included angle vector of the adjacent frames is utilized as the index value, and finally the dynamic time bending algorithm with the lower bound function is utilized to calculate the similarity between the searching example and the candidate segment. By means of the method, motion capture data searching is achieved accurately and quickly, the searching accuracy is improved, and the searching time is shortened.

Description

technical field [0001] The invention belongs to the technical field of motion capture, in particular to a motion capture database retrieval method based on a dynamic bending algorithm. Background technique [0002] In recent years, the animation industry represented by animation, comics, and online games has become a new economic growth point in developed countries. The world's animation industry is mainly concentrated in Europe, America, Japan, and Korea. The United States is one of the earliest and major developing countries. Its animation industry has taken the lead in the global animation industry; Japan, as a major exporter of animation products, occupies an important position in the international market with its strict industrial chain structure and mature operating mechanism. In developed countries, the animation industry is not only important, but also It is one of the pillar industries, and the total annual market is tens of billions or even hundreds of billions of ...
