| Abstract: | A detection and control methold based on the combination of the positioning and measurement in the real time embedded machine vision systems is presented. To solve the problem that the industrial detection is of lower accuracy and can not be completed in a real time way by embedded machine vision systems due to large computation cost, a detection method is proposed based on the point set, the Hough transformation and the least square fitting algorithm. The industrial detection experimental results show the workpiece detection accuracy based on the method is better,the tolerance is higher, and the detection time is lower than 2.0ms/time. |
