一种角色运动轨迹提取及重定向的方法

Method to extract and retarget the character motion trajectory

随着计算机图形学和动漫产业的快速发展,通过计算机实现运动编辑和运动重定向技术,形成角色动作库进行重复利用,成为快速生产动漫作品的一个重要手段。提出了一种角色运动轨迹提取及重定向的方法。该方法通过记录角色末端关节的运动轨迹,通过一定的归一化规则提取建立角色运动轨迹库,利用CCD逆向运动学解算器重定向至另外一个角色,实现角色动作的重复利用,达到了较为理想的效果。

With the rapid development of computer graphics and the animation industry, it becomes an important way to produce ani- mation works by using computer to realize motion editing and retargeting and build the character motion library for reuse. This paper in- troduces a character motion trajectory extraction and retargeting method. This method can realize the reuse of the character motion by recording the motion trajectory of a character＇ s end joint, using certain normalization rules to extract the trajectory and build a charac- ter motion library, and retargeting to another character by a CCD IK solver, It proves that such method is ideal.
