Min Zhong, ZENG Jiguo, Xusheng Xie · Physics Procedia · 2012
Panorama stitching algorithm based on scale invariant feature transform and Levenberg-Marquardt optimiza-tion is proposed. Mapping the source planar images to a cylind-rical surface is the first step. Then, correct matching feature pairs are detected between two images by SIFT and RANSAC algorithm. Finally the Levenberg-Marquardt algorithm is used for calculating the initial estimates of motion parameters. Experiment results show that this method is effective against the hand-held camera motion with small rotation around the optical axis, small horizontal and vertical movement.
