摘　　要：讨论了贴片机机器视觉系统中机器图像处理的主要过程和实现方法。分析了几种常用的图像平滑技术并在仿真实验的基础上选用中值滤波的方法来实现图像滤波。针对阈值图像分割技术,对全局阈值的选择方法进行了分析比较,实验表明最大类间方差法分割效果较好。Main process and realizing method of image processing in surface-mount machine visual system were discussed. Analysis was made to several usual image smoothing techniques and on the basis of simulation experiment, median filtering method was used to realize image filtering. Aiming at threshold image segmentation technology, selecting method for global threshold was carried out with analysis and comparison. Experiment shows that maximum between-cluster variance method to divide is better.
