Anti-Viewpoint Changing Image Matching Algorithm Based on SURF
especially great viewpoint changing between the real-time image and the reference image
an anti-viewpoint changing image matching algorithm based on SURF is proposed to bridge the gap of the original one
which may lead to failed matching for the lack of correct matched pairs. The proposed algorithm simulated possible perspective transformations from the original image
generated a set of simulated image sequences
and extracted SURF feature points in the sequence images. Then
the feature points of the simulated image sequence were mapped to the reference image. Finally
the matching point pairs are obtained by the method of the euclidean distance criterion. Experiment results show that the proposed algorithm increases the matching pairs of the feature points
and overcomes the influence of viewpoint change (more than 60) in image matching.
