Abstract: In order to solve the problem of band registration of coated dual lens multispectral camera, a fast registration method based on improved SURF (speeded up robust features) algorithm is proposed. Firstly, the distortion of each band image is corrected. Then, the fast version of SURF algorithm (F-SURF) is used to register the undistorted band images. Compared with the original SURF algorithm, the F-SURF algorithm optimizes the number of octave, discards the rotation invariance and introduces the PROSAC algorithm. The experimental results indicate that the registration accuracy of the F-SURF algorithm is better than that of the classic SURF algorithm, and the time efficiency is significantly improved.
