Abstract: Aiming at the complexity of image line feature matching,we propose a matching strategy turning to the establishment of object topology relation table of describing object structure based on the object structure information.The method takes advantage of the graphical relations of image point and line features obtained by image feature extracting to build object topology relation table of describing object structure.Candidacy polygon features are acquired through segmentation geometry graphics of left and right image.The arc-polygon file of association graph of left and right image is obtained using vector data topology relation automatism algorithm.Then,the transmission match is carried out by the method of depth-first traversal based on base match and topology relation table.As the relationship tables consistency shows the composition of objects,features elements of consistency,the matching search scope of whole image is made smaller,thereby the image matching accuracy and speed is enhanced.
