Abstract

In this paper, we propose a novel method to represent 3D dynamic objects, which are captured with a laser scanner in successive time instances. The objective is to convert an input mesh sequence into a semi-regular mesh sequence with time-invariant topology information, since it enables the easier manipulation of 3D data using many signal processing techniques. We achieve this objective by performing global motion estimation, local deformation estimation, and correspondence optimization subsequently. Simulation results show that the proposed algorithm reconstructs the original geometry faithfully. Furthermore, the resulting semi-regular mesh sequences can be effectively compressed by adopting wavelet coding schemes.
基于对应匹配的三维动态物体的半规则网格表示
在本文中,我们提出了一种新的方法来表示三维动态目标,这些目标是用激光扫描仪在连续的时间实例中捕获的。目标是将输入网格序列转换为具有时不变拓扑信息的半规则网格序列,因为它可以使用许多信号处理技术更容易地操作3D数据。我们通过进行全局运动估计、局部变形估计和对应优化来实现这一目标。仿真结果表明,该算法能忠实地重建原始几何形状。采用小波编码可以有效地压缩得到的半规则网格序列。
