Presentation Abstract

As more data sources have become abundantly available, an increased interest in 3D reconstruction has emerged in the image processing academic community. Applications for 3D reconstruction of urban and residential buildings consist of urban planning, network planning for mobile communication, tourism information systems, spatial analysis of air pollution and noise nuisance, microclimate investigations, and Geographical Information Systems (GISs). Previous, classical, 3D reconstruction algorithms solely utilized aerial photography. With the advent of LIDAR systems, current algorithms explore using captured LIDAR data as an additional feasible source of information for 3D reconstruction.
This proposal presents an outline for the development of an autonomous 3D reconstruction algorithm. The algorithm will analyze key features extracted from both LiDAR data and aerial imagery of a given scene and, without user intervention, isolate building structures and then reconstruct 3D models depicting those building structures. The motivations behind already determining several key characteristics about the design of the reconstruction algorithm (such as using a data dependent as opposed to model based algorithm) are presented. Comparisons to previous works contrasting design methodologies are also included.
