对于安装的印刷电路板检测，要求检测系统检测元件的三维位置。为了检测零件的三维位置，介绍了一种由多个CCD摄像机组成的三维视觉传感器。该系统通过对立体图像的处理，实现了对物体三维位置的测量。对于电子元件，可以定义PCB板上的预期位置。从而简化了立体图像处理的方法。只需在每个部件上准备一条测量线就可以检测到其位置。为了在线上进行立体图像处理，可以应用动态规划对局部变形的两幅图像进行立体匹配。将DP方法引入到立体匹配中，实验系统证明了其精确的三维位置检测能力。
For the mountedprinted circuit board inspection, the inspection system is required to detect the 3-D position of the components. To detect the 3-D positions of components,a 3-D vision sensor with multiple CCD cameras has been introduced. The system executes the stereo image processing to measure the 3-D position of he objects. For the electric components, the expected position on he PCB boards can be defined. So, the method of stereo image processing is simplified. Only preparing a measuremen line on every component is enough to detect its position. To perform the stereo image processing on the line, Dynamic Programming can be applied to perform the stereo matching between the locally deformed two images. Introducing the DP method to the stereo matching,the experimental system has been proved its precise 3-D position detection ability.
