摘要
本文介绍由多视图近似重构三维物体的基本方法,文中采用三维实体表达的八叉树方法,给出了表达视锥的基本数据模型及构造视锥八叉树的基本方法。
In this paper,the methods of reconstruction of 3D object by using Multiple views are in- troduced.The octree representation of 3D Solid models,data model of polyhedral view cones and construct of algorthms of view octree are described in detail.The way of application above methods to the research of atomizing area in flood—relief of high—lift dam is discussed.
