LOAS is a model-based interpretation system designed to recognize and to locate sites using a 3D model. Two concurrent sensors of different types provide two views of the same area with a different point of view. This redundancy is the important source of 3D recognition. The system is organized around two major phases: Model description and 2D data segmentation versus 3D scene description. Attention is focused on using 3D information as soon as possible before the matching which is performed on a subgraph pyramid basis.
