摘要：This paper proposes a method for buildings change detection. Vertical edges of buildings are extracted in pairs of aerial images respectively, taking advantage of the character that vertical edges intersect at their vanishing point without fail. The ground coordinates of the vertices on each vertical edge are calculated according to projection difference and the principle of frontage intersection. And the changes of buildings are detected by carrying on the change analysis using these coordinates and the three dimensional city models. Finally, experiments are given. The results show that the approach proposed by this paper is feasible and the changes of buildings can be detected accurately
