摘要
区域检测,即判定当前点是否位于某个已知的区域之内,这是电子地图处理和计算机图形学以及目标定位中经常遇到的问题。对于任意区域的检测目前尚无很满意的方法,文中给出的基于参照点的检测方法,思路清晰、实现简便,且适用3维空间任意区域的检测。
Region detection means to identify a point whether it is in a known region. It is a general problem in electronic map processing and computer graphics as well as the target location. There has not been a satisfying method for random region detection until now. In this paper, a detection method based on reference point is presented, whose reason is clear. its realization is handy and it is applicable to threedimensional random spatial region detection.
