Abstract: Traditionally,image registration approaches are classfied to two categories: area-based methods and feature-based methods,where the latter use corresponding features as control elements.An automatic images sequence registration method is proposed which using corresponding line segment features as control elements.According to the collinearity principle of corresponding line segment features,the image registration model is established.With this registration model,people need only to specify corresponding line segments,but does not need to locate their end points.This method break out the limitation about the corresponding features must be the same.Meanwhile,to realize the automatic registration of image sequence,the algorithms for automatic line extraction and automatic line matching is designed,which satisfy the demands of image registration,under the supposition that the images have overlaid roughly.
