| 摘 要： | 在城市空间三维表现中,针对复杂自然景观的地形地貌大多采用不规则三角网TIN模型表现。为节约存储空间,在参照JPEG压缩技术中的用户兴趣域编码思想（RO I）结合边收缩算法的基础上,实现用户兴趣域以外的其它区域进行简化,只对用户兴趣域保持较高分辨率。本算法在简化过程中同时生成过程文件,保证了模型连续多分辨率的重建。

| Abstract: | While displaying city space in the three-dimensional way,it is common to present natural landscapes by using the triangulated irregular network(TIN) model.In order to save storage space,the problem is solved on the basis of border contraction algorithm combining with the conception of domain of user interest(ROI) in JPEG compression technique.We simplify the reign beyond the interest of users to maintain a high resolution.A document is generated while the algorithm is simplified,which ensures the reconstruc... |
