Abstract

The invention relates to a motion control and animation generation method based on an acceleration transducer. The invention belongs to the technical field of computer virtual reality, in particular to a motion control and animation generation method in computer animation technologies. The method comprises the following steps of: firstly, analyzing a motion to be recognized to obtain key joint point information in the motion process; then, extracting the features of transducer data and motion data in the position of the key joint point based on physical meaning, and carrying out subsequent motion classification and motion recognition. Signals are segmented and a motion recognition classifier is created according to the characteristic sequence of the signal data of the acceleration transducer, and characteristics based on kinetic energy are used as central characteristics to match with bone motion data; in order to increase user experience, the time sequence of the finally obtained recognition motion result is adjusted so as to conform to the motion time sequence of on-line performance of a user. The invention has the characteristic of realizing real-time interactive control on virtual human whole-body motion by using a few transducers.

Description

technical field

[0001] The invention belongs to the technical field of computer virtual reality, in particular to a motion control and animation generation method in computer animation technology. Background technique

[0002] With the continuous development of virtual reality technology, real-time virtual character motion control technology has been widely used in more and more fields such as animation, games, and virtual reality systems. For real-time virtual character control technology, a good user control interface plays a decisive role. Although the motion capture system can accurately capture the movement of characters, and then apply it to virtual character control, dynamic surface generation, etc., it also has many disadvantages, such as: the whole set of equipment is heavy and expensive; because the whole set of systems needs to be arranged in a fixed space, The types of sports that can be collected are limited; the collected data is in a high-dimensional space, a...
