Method for compiling three-dimensional human skeleton motion based on motion capture data

Abstract

The invention discloses a method for compiling three-dimensional human skeleton motion based on motion capture data. The method comprises the following steps of: analyzing and judging a similarity of the states of connecting points of segments to be moved and judging whether a transition motion segment is to be added; after eliminating a relative position difference between the motion segments, linking a plurality of motion material segments into a new motion segment meeting the requirement; when jumps are generated due to the inconsistence of the beginning and the end motion gestures of the motion segments in the linking process, making the transition at the joints among the segments smooth and natural by using a transition function at jump positions; when a sliding phenomenon occurs in the motion due to the use of the transition function, breaking apart a fixed skeleton model hierarchical structure and rebuilding at the moment, and eliminating the sliding by using a reverse kinematic principle, wherein the newly built skeleton model hierarchical structure is also applied to adjustment of a motion orientation of a role model as required at the same time; and finally, carrying out a combined compiling on different types of motions so as to greatly expand richness and diversity of the generated new motion types.

Description

technical field [0001] The invention belongs to the technical fields of computer graphics and digital entertainment, and relates to a method for motion editing based on a motion capture device. Background technique [0002] 3D character animation has important applications in 3D game design and 3D movie production. The motion editing system has a strong demand for the reusability of motion capture data, the fidelity of animation effects, the quickness of the processing process, and the ease of operation. . Therefore, it is of great significance to study convenient and efficient motion capture data editing methods for practical applications. [0003] At present, 3D human animation technology can be generally divided into three categories: [0004] The first category is kinematics-based human animation. This type of method abstracts the human body model into a tree structure, and regards the limbs and torso as qualityless connections between multiple segments. According to...

Problems solved by technology

However, the realism of even the most advanced motion generation techniques cannot match the realism of human motion, and previous methods of both types are significantly more computationally expensive

The method based on motion capture well preserves the realistic effect of motion, but the cost of purchasing motion capture equipment and contacting actors to perform corresponding actions is high. Therefore, it is very important to improve the efficiency and value of data through motion capture data editing technology. significance
