Paper Abstract

How to perform initial match is a key problem of automatic image matching. This paper proposes a point pattern matching algorithm to match two point sets coarsely using affine invariants, area ratio of adjacent triangles. Its process is to constitute triangulated irregular network (TIN) by point sets, search the homonymous triangles by area ratio and affine transformation equations, and then establish initial mapping relations between two point sets, finally use least square matching to match them accurately. Experiments show that it can match two affine transformation point sets automatically without manpower-intervention and other auxiliary information.
