摘要
该文提出了一种以凸包为基础来表达物体表面近似轮廓模型的方法。通过对由各种方式所得的散乱点集进行预处理,然后进行凸包运算,求得物体表面轮廓极值点,再依据这些点进行物体表面的三维重建。该文以Visual C++6.0为开发平台,采用可视化类库VTK,对这一方法进行计算机仿真,取得了较为理想的效果。
In this dissertation,A method was presented to get the approximate surface contour model of the object based on con vex hull.Through doing convex hull operation on scattered point sets gained from various method which was pretreated could obtain surface extreme point of the object.Then rebuilt the surface of the object according to these points.In this article taking Vi sual C++ 6.0 for platform,using visualization class library VTK,we also did computer simulation of this method.and got a compa rable ideal result.
