A fast non-Hough method for circle detection
LI Liang-xian · Journal of Henan Polytechnic University · 2010
Precision measurement,automated assembly and robotics fields often require an identification and location to a circular object or icon.The current detection method is based on Hough transform,which is complex in computing and requires much resource.A non-Hough method is proposed,which can recognize circular targets in color image by making use of the symmetrical property of circles and adopting the segmentation method based on color.The experiments of applying this method to the location of soccer robot show that the method can calculate quickly and adjust to deformed circle.The algorithm of quickly identifying circular target provides a reference in image processing.
