A Mosaic Method for Aerial Image Sequence by R/C Model

An economic and simple scheme to obtain wide field range of aerial images is proposed, the scheme includes only an aerial model taking a camera. For the obtained video an automatic image mosaic technique is used. Firstly a lot of feature point pairs are extracted by SIFT (scale invariant feature transform) features between two adjacent frames, and Ransac (random sampling consensus) is used to pick out bad matching, then homography matrices are calculated, including adjacent frames and non-adjacent frames (cascade of homography matrix), finally a large mosaic image is formed using the homography matrices. The experiment proves that our method can make very wide filed vision of aerial images with high quality.
