摘　　要：介绍了微操作机器人显微视觉系统的构成,自动调焦系统的必要性。提出了双向差分绝对值函数作为自动调焦评价函数,在20μm范围内以变步长实现了正确聚焦,获得质量较高的图像效果,为进一步实现微操作打下基础。The structure of micro-vision system for micromanipulation robot was introduced and the necessity of auto-focus system to micro-vision system was expatiated. A new evaluation function of total absolute differential value was put forward. In the range of 20μm, the correct focus was gained and good image was obtained, this is a good foundation to further implement of micromanipulation.
