Round Paper Tray Grabbing Detection Based on Hough Transform Optimization

摘要

For various problems such as poor precision, too long calculation time and too large storage amount in the detection of the target circle, an improved Hough transform based on target circle detection method is proposed. The method first uses connected component labeling on the target image, and obtains roundness value by getting on roundness calculation. Then we set the threshold to estimate the approximate location of the connected component of the target circle, and get on double detection on the target with external influence by performing Hough transform and fitting circle operation. We calculate the difference between the radius and the center of the circle, and the results improve the computational efficiency and detection accuracy.
