| 摘 要： | 模型引导法是一种简单、方便的三维重建方法 ,由于轮廓搜索过程的需要 ,该方法要求用于重建的投影数据必须有完整的基于图元的点数据。一般情况下 ,输入的投影图文件中没有反映图元间位置关系 ,所以不能直接建立完整的点数据表。本文提出了由图元位置关系获取点数据的算法以及如何预处理投影图数据 ,以建立完整的点表。该算法在实体重建中已达到预期的效果。

| Abstract: | The model-oriented approach is one of the methods of 3D solid reconstruction,which is simple and convenient to rebuild 3D solid. It need to build complete point data table based on the projection view date in searching of view contour. In general,the input data do not reflect the position relations between two view items,so the integrated point data table can not be built directly. A method for obtaining point data by means of analysis of the position relations of view items,and an algorithm for pretreating input projection view data are presented in this paper. Good result are obtained when the algorithm is used in 3D solid reconstruction. |
