Building Model Reconstruction from Data Integration

Building model reconstruction has been attracting a great attention from researchers in the geomatics society all over the world. Buildings provide essential information to urban planning, tourism, telecommunication, homeland security, and many others. Much building reconstruction research has been conducted on aerial photographs and LIDAR point data. Some studies are commenced by researchers in last few years to explore the integration of LIDAR and aerial photographs for building model reconstruction. In this paper, a methodology of 3D building model reconstruction will be examined based on the integration of aerial photographs and LIDAR data. The methodology is comprised of two elements. The first one is to reconstruct 3D building models from LIDAR data. Rough building models are the outcome of this step. The second element is to refine the rough models with information derived from aerial photographs. The research will focus on the model refinement process. It will also address the issue of co-registration of LIDAR data and aerial photographs.
