摘要
Abstract
To meet the requirement of fastness and accuracy of doorknob image feature extraction and matching,an improved SURF algorithm is proposed,which mainly targets the problem that it is hard to extract a large number of information points at the smooth area of the image.In addition,the edge detection algorithm is added.With morphological processing,dilation operation and open operation,the image edge information of doorknob was obtained and the key point was extracted,hence some more featured information were collected.The results show that the improved SURF algorithm can extract feature points in the smooth area in real time with obvious improvement in the accuracy rate of matching.关键词
