This　article　presents　a　fast　method　for　image　mosaic　based　on　SURF.　The　method　includes　three　principal　steps:　Firstly,　the　feature　points　are　extracted　using　SURF　operator　and　the　feature　points　are　matched　using　BBF　algorithm;　Secondly,　image　registration　is　completed　by　estimating　the　converting　relationship　between　images　with　the　RANSAC　and　least　squares　method;　Finally,　seamless　image　fusion　is　obtained　by　using　Gradating　in-and-out　amalgamation　algorithm,　which　can　reduce　the　effects　of　seams　and　illumination　variations.　The　experimental　results　demonstrate　that　this　method　has　superior　quality　of　stitching.
