In order to obtain accurate aerial stitching images
a new algorithm combined with Binary Robust Invariant Scalable Keypoints (BRISK) and cross-correlation template matching algorithm is proposed in this thesis. There are some errors in the splicing translational direction on using traditional BRISK algorithm in image mosaic. Aiming at the problem
the BRISK algorithm is firstly used for the scale and rotation correction of the matching images. Then the template matching method is used for the translation correction. Meanwhile
the random sample consensus (RANSANC) algorithm is added to the BRISK algorithm to achieve precise mosaic. The experiment results show that the proposed algorithm has short operation time
high precision
and can achieve good image mosaic results.
