Embodiment Construction

[0031] Below, a preferred embodiment of the present invention is described in detail with reference to accompanying drawing:

[0032] see figure 1 , this low-cost motion capture and demonstration system consists of the following parts: two CCD cameras 1L and 1R installed at relatively fixed positions (relative distance 50cm±5cm); the images collected by the cameras are transmitted through the DH-VT121 image acquisition card 2 For the EC5-1719CLDNA embedded processor 3, save the database 4 of real-time joint point data, and the embedded processor 3 extracts the joint points in the database to reproduce the human body posture model and the three-dimensional animation character posture on the display 5.

[0033] Marking point: Performer 6 wears a special pure black performance costume, and binds 14 ribbons of different colors at a reasonable position on the costume as a marking point. Ribbon binding joint positions such as figure 2 shown. Think of the movement of the human bo...

Abstract

The invention relates to a system and a method for low cost motion capture and demonstration. A performer wears a suit of demonstration clothes provided with joint signalized points, and the demonstration clothes use black color as a ground color; each main joint is tied with ribbons with different colors as signalized points; a double-CCD camera acquires motion image information of the performer, and then transmits the acquired data to an embedded process through an image acquisition card; and the embedded processor captures the signalized points dynamically through a self-adapting algorithm, calculates three-dimensional coordinates of the signalized points through a binocular stereo vision technique, and stores the three-dimensional coordinates in a database, thus the reappearances of a skeleton model and three-dimensional animations are achieved on a display according to the coordinates in the database, and the current positions of the signalized points acquired by the system are exhibited intuitively for the convenience of debugging and demonstration.

Description

technical field [0001] The invention relates to a low-cost motion capture and demonstration system and method designed and developed based on binocular vision technology. Two cameras are used to dynamically capture the motion state of a performer, and a three-dimensional animation model is used to demonstrate the motion of the performer in real time. Background technique [0002] Motion capture technology emerged in the 1970s when Disney wanted to capture the movements of actors to improve animation. When computer technology has just been applied on a large scale, Rebecca Allen of the New York Computer Graphics Technology Laboratory designed some optical devices as a reference for animation production, and the actors' performance postures can be projected on the computer screen. With the rapid development of computer software and hardware technology and the improvement of animation production requirements, motion capture technology has attracted the attention of more and mor...
