This paper concentrates on the study on the map fusion problem in the context of a multi-robot map building approach. Concretely it is seen as one of the steps towards the independent multi-robot map building. In the situation proposed a set of several robots performs map building tasks without the notion of other robots’ existence. Each robot builds its own local map using its observations and...

This paper describes a knowledge-based approach to automatic 3D reconstruction of buildings from aerial imagery. The approach relies upon the use of 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 ...
