Medium and low altitude CCD image Stitching based on SUFT algorithm

Abstract:
Aiming at the problem that the left and right tilt images of middle and low altitude CCD camera have different sizes and large deformations from the images in the middle two bands, image stitching is more difficult, a method of middle and low altitude CCD image stitching based on the SUFT registration algorithm is proposed. First, used the SUFT algorithm which is sensitive to feature points, strong in anti-interference and high registration accuracy to register the image, and then used the RANSAC algorithm to remove the mismatched points; Then, the registered images are fused to eliminate the Stitching seams, so as to realize the seamless stitching of the image. The experimental results show that the algorithm can accurately register and stitch each strip of the mid-to-low-altitude CCD image, ensuring the integrity of the target, and facilitating the identification and interpretation of the target by the intelligence processing personnel.
