摘要
Abstract
In response to the problems of traditional line matching methods such as easy omission,weak matching,and poor specificity of some line descriptors,we proposed a line segment matching algorithm combining irregular line segment descriptors with geometric constraints.We used the data of four different image transformation types in the open network data set to verify this algorithm,and compared it with other algorithms.The results show that the average correct rate of algorithm is improved by 27.5%,14.2%and 1.2%respectively,and the average numbers of correct matches are increased by 247,290 and 182 respectively,effectively illustrating the effectiveness and accuracy of this algorithm.关键词
