Abstract

Automatically extracting object models from images is a complex task. We describe research in extracting 3D models of buildings from aerial images. This work has resulted in several related systems including assisted extraction (minimal manual interaction to guide automatic processing), automatic extraction with limited imagery and limited building models, and automatic extraction with very good imagery and digital elevation models and more complex building models. Some results are provided for the assisted system and one of the automatic systems.
