Instead of 640 fibers , it realized the large area multi - object observation by use of 4 000 fibers . according the request of project , mechanical character , controlling and positioning method were firstly analysized . then through studying geometry modeling , convex hull , polygon collision test and other arithmetic , the positioning , controlling and collision test method are proposed which are suitable for radial coordinates unit
本文根据工程的要求，首先对光纤定位装置的机械特征、控制方式、定位方法做了分析，然后通过研究现有的几何造型、凸包构建、多边形碰撞判断等算法理论，研究出适合极坐标运动单元的表示、控制、判断方法，并最终在虚拟系统中实现了4000个光纤定位单元的存储表示、定位控制、碰撞判断(即实时监控) 。
