Localization of Building Corners in Aerial Images

چکیده
This paper describes a knowledge based approach for automatic 3D reconstruction of buildings from aerial imagery. The approach relies on using a 2D GIS map and knowledge about the imaging geometry and acquisition parameters. We show that by integrating knowledge from the images and the GIS map, the complexity of the building reconstruction process can be greatly reduced. In the first stage the buildings are localized in the images based on information about the ground plans of the buildings contained in the GIS map. This restricts the processing at all following stages to one building structure. To reconstruct a building we propose a hierarchical method based on hypotheses generation and verification. The information contained in the GIS map constrains the possible interpretion of the images and can also improve the results.

متن کاملFusion of aerial images and sensor data from a ground vehicle for improved semantic mapping
This paper investigates the use of semantic information to link ground-level occupancy maps and aerial images. A ground-level semantic map is obtained by a mobile robot equipped with an omnidirectional camera, differential GPS and a laser range finder. The mobile robot uses a virtual sensor for building detection (based on omnidirectional images) to compute the ground-level semantic map, which ...
