High precision registration of monochrome and color video based on improved SIFT and mutual information method
Fig. 1. Registration effect and improved registration effect.（a）Monochrome video frames；（b）Color video frames；（c）Original RANSAC effect；（d）Improved registration effect.
Fig. 2. Comparison of the effect of traditional SIFT method and the first frame alignment method in this paper.（a）Monochrome video frames；（b）Color video frames；（c）Registered monochrome images obtained by the improved method；（d）Monochrome images after further alignment optimization；（e）Board alignment chart after SIFT alignment；（f）Further alignment-optimized board alignment diagram；（g）Local area with 1 pixel error；（h）Error is barely visible in the local area of the vegetation after correction. After further alignment optimization，the position is more accurate on both sides of the image，and the marker point error is reduced from 1 pixel to almost invisible.
Fig. 3. Registration effect of continuous video frames.（a）Monochrome video frames；（b）Color video frames；（c）Monochrome video frames with registration；（d）Chess and card registration map.
