Description This papers describes an algorithm to estimate the precise position of facade planes in digital surface models (DSM) reconstructed from aerial images using an image-based optimization method which exploits the redundancy of the data set (along and across track overlap). This approach assumes that a facade is a vertical plane and that the heightfield is precise enough to generate hypotheses for the initialization of the optimization algorithm. The initialization is first roughly oriented using the principal line directions of its texture, afterwards a hierarchical algorithm performs a finer optimization to maximize the correlation across different views. The proposed method is applied to real world imagery and its results are shown. 1
