不规则区域内随机取点的算法设计

The Design of an Algorithm for Random Accessing Point in an Irregular Area

在不规则区域中按随机抽样原则取点,是工程应用领域中的常见问题,所取点应该服从在该区域上的均匀分布。针对平面区域给出一种在不规则有界闭区域中随机取点的算法,并在讨论球面图形及其面积的计算方法的基础上,类似给出了球面区域上的有界区域中随机取点的算法。

It is common to access point randomly in an irregularly closed region in engineering applications.And the access point should be uniformly distributed in the region. This paper gives an algorithm design for how to select a point randomly from an irregularly closed region in the plane area. Meanwhile,it presents the algorithm of random point in the bounded region of the spherical area based on discussing the calculation method of spherical graph and its area.
