Improved real-time camera video mosaic method

Aiming at the problem that the general camera's field of view is too small, by collecting two frame images from different cameras which have some overlap regions simultaneously, the SIFT algorithm is used to find the video frame image feature points; the Dichotomy Based Hash(DBH)algorithm is used to match the SIFT feature points; the Random Sample Consensus(RANSAC)algorithm is used to eliminate the false matches, and the mosaiced video can be obtained. Experiments show that this method can mosaic the video frame in real-time effectively. In addition, the method is feasible to low overlapped(even to 10%)video image.
