Multiple-step path planning algorithm for automated optical inspection system

针对检测表面贴片产品缺陷的光学检测系统,提出一种三阶段的快速路径规划算法。该算法前两个阶段形成初步的检测路径,第三阶段利用顺序检测窗口的几何关系,迭代的调整检测窗口的中心位置,以减少检测路径长度和检测窗口数量。最后仿真实验证明了该算法是一种实用的快速的规划算法。

A fast three-step path planning algorithm was proposed for automatic optic system to inspect electronic product defects by using surface mount technology. In the first two steps,the algorithm generated a basic path. Based on geometric relation of optical inspection windows,the algorithm relocated the windows center to reduce moving distance and the number of windows. The simulation experiments show that the new planning method is practical and fast.
