Abstract
The LADAR(Laser Detection and Ranging) occupies an important position in the laser guidance technology, completing mosaic of LADAR image and achieving LADAR image of big scene is important significance for the laser guidance technology. SIFT algorithm can extract image feature points effectively, and realize feature matching through these feature points precisely, Then using the RANSAC method can obtain homography matrix between two images. Through the homography matrix effect, we can get the image of registration, then we make image to be fusion. The last we obtain the image to be mosaicked. In the experiment, we use LADAR intensity image as input image, and verify good mosaic result of SIFT algorithm through MATLAB software.
