摘要：In this paper we report on a system to extract 3D information from oriented digital facade images using various feature extraction/matching methods. We emphasize on 2D feature extraction from digital images including contour chains, line segments and vanishing points. The extraction of 3D primitives is based on line matching over multiple oriented views and 3D plane detection by a line grouping process. The MetropoGIS system is designed for the automatic extraction of 3D data from facade images
