摘 要: 三维成像及造型系统 (3DIMS)通过对物体不同方向的数据采集 ,完成深度数据的匹配和融合 但由此得到的图像数据量庞大 ,质量也不能满足计算机动画等应用的要求 针对这一问题 ,将网格优化和细分曲面引入到对该三维数字图像的后处理过程 实验结果表明 ,该方法在数据压缩和曲面的表达等方面较 Three-dimensional Imaging and Modeling System (3DIMS) often collects range data of the object from different views, then completes the registration and integration of several partial images. However, data volumes of the resulted image are very huge and the image quality is not good enough to satisfy the demand of some applications such as computer animation. Mesh optimization and surface subdivision are needed to post-process the synthesized image. Experimental results indicate the improvement in terms of data volume and surface representation in comparison with the image obtained directly by 3DIMS.
