基于视频的虚拟人群运动仿真方法
Motion Simulation Method for Virtual Crowd Based on Video
摘要
Abstract
The existing massive crowd animation simulation methods have the defects of low quality and low efficiency in simulation. In order to solve these two problems,this paper proposes a method of combining storyboard with texture synthesis algorithms which can efficiently generate large scale crowd animation. Crowd’ s positions,standing directions, status and information from the first frame including characters ’ path information from the subsequent frames are extracted and stored in the sample storyboard. And combining with block-based texture synthesis method, this sample storyboard can be used to enlarge the size of crowd efficiently. The final large-scale crowd animation can be simulated by using the enlarged storyboard in combination of simple collision detection algorithms. Experimental results prove the high efficiency and quality of this method in generating realistic large-scale virtual crowd animation.关键词
