A Feature-Index based algorithm that uses similarity information and spatial coherence is presented in the paper. It especially ¯ts to the case that the base image is very large and real-time property is needed. The algo- rithm is divided into four steps: ¯rstly extract features from base image, and establish feature-index table before- hand; then extract corresponding features from sensed im- age and use the feature-index table to match them with those from base image; thirdly, fuse the matching results of Main line pairs (MLPs) and contours; ¯nally, solve the transformation parameters using the intersection points of MLPs and centers of contours and complete registration. The experiment results show that the proposed algorithm is accurate and e®ective.
