Abstract: Registration between catadioptric omni-directional image and satellite remote sensing image has long been a topic of research in computer vision.There has been increasing demand of the registration approach over the last decade.Unfortunately，few methods have been presented to effectively solve this problem.This paper proposes a fast semi-automatic registration method by analyzing angle relations.It extracts the edges of buildings top side from the omni-directional image by using omni-directional Hough transform，and manually marks the corresponding edges on the satellite view image.It computes all possibility positions that the omni-directional image can be captured through a voting process.It locates the best position from all the candidates.It has demonstrated on experiments that this method is accurate and efficient for the registration.
