In this paper, after summarize the main existent methods, a new 3D center path finding algorithm base on two distance fields is proposed: Between any given start-point and end-point which can be connected, the source distance field base on the start-point and the boundary distance field base on the boun.
为了解决当前中心路径自动 提取算法中存在的效果差,计算量大的问题,提出了一种基于双距离场的快速三维中心路径提取算法,该算法对于 任意给定可连通的起点和终点,首先建立基于起点的源距离场和基于边界的边界距离场,然后通过两个距离场的 共同约束来快速地提取出一条连接起点和终点的中心路径,同时为了保证漫游的效果,还采用3次B样条曲线对 所获取的路径进行了光滑,最后在PC机平台上实现和测试了该算法,实验结果证明,该算法不仅速度快、效果好, 而且具有很高的灵活性。
