At first, the location interrelation is concluded between two special line segments.
通过总结提炼两空间线段间的相互位置关系,在进行解析、推导的基础上,提出了7个有意义的解析几何推论,直接可得出两空间线段间的最短距离,然后根据得出的结果,设计了一个机器人运动关节间的碰撞检测算法。
According to the corner feature that the little neighborhood of the corner point contains two or more than two lines,so we can compute the amount of lines.
根据角点的边缘特征(角点的一个小邻域内包含两条或两条以上的线段,而一般的边缘点的邻域内则只包含一条线段),计算出每个点的小邻域内包含的线段数,便可以确定该点是否为角点。
