摘　　要：针对生物工程领域显微操作的要求和特点 ,设计并实现了一个显微视觉系统 .该系统采用基于相关系数的模板匹配算法和基于形态学运算的识别算法 ,能同时获得至少 3个目标的二维位置信息 .这两种算法均可由能够用硬件并行实现的离散卷积运算来实现 ,从而能够快速地计算目标的位置信息 ,实现了实时视觉伺服控制 .实验结果表明视觉伺服控制能有效地提高系统的性能 ;A micro vision system was presented to meet the requirements of micromanipulation in the field of bioengineering. A correlation based pattern matching algorithm and a morphological method, which can be realized in the form of easy fast implemented discrete convolution, were employed to track at least 3 targets simultaneously and to calculate their image coordinates. The coordinates were used as feedback message to realize visual servo control. Testing results proved that the vision servo control could effectively improve the control quality. This implies that the vision system can meet the stringent needs of real time control.
