eedimensional reconstruction of the building systems, design the corresponding algorithm to reduce end user workload. The main contributions are the following: 1 .Present a building reconstruction and modeling system which allows novice users to create textured polygonal models from a set of photographs of a building. 2. At present, the extracted information contains too many inconsistencies, missing features, and unwanted noise to be pletely reliable. Therefore, we aim at creating a semiautomatic solution which helps reduce steps in footprint drawing process and increase the accuracy of the result. 3. Exacting building footprint from point cloud. We have designed an algorithm to predict the continuation of a usertraced line segment
