文章摘要
近年来,在虚拟现实(VR)技术及其相关产业的大力推动下,三维动画制作技术迅猛发展,同时也对三维动画的分析和处理技术提出了更高要求。其中,三维动画的压缩处理是实现三维动画数据高效分析、存储和传输的关键技术。提出基于三维模型的动态行为计算跨域时空分割算法,实现区分三维模型的刚性分割和动态时空域分割,并借助经典的主成分分析算法实现了对刚性和动态分割的压缩。实验结果表明,对于长序列动画,所提出的基于时空分割的三维动画压缩方法,在更低误差情况下可实现更好的压缩效果。
Abstract
In recent years, with the vigorous promotion of virtual reality (VR) technology and its related industries, three-dimensional animation production technology has developed rapidly. At the same time, higher requirements have been put forward for the analysis and processing technology of three-dimensional animation. Among them, the compression processing of three-dimensional animation is a key technology for efficient analysis, storage, and transmission of three-dimensional animation data. This paper proposed a cross-domain spatio-temporal segmentation algorithm based on three-dimensional model for dynamic behavior calculation, which realized rigid segmentation and dynamic spatio-temporal domain segmentation for distinguishing three-dimensional models, and realized rigid and dynamic segmentation compression with classical principal component analysis algorithm. The experimental results show that for the long sequence animation, the three-dimensional animation compression method based on space-time segmentation proposed in this paper achieves better compression results under lower error conditions.
