Abstract
This chapter discusses the representation of obstacles in an environment with planar ground through wide baseline set of images in the context of teleoperation. The camera parameters are assumed to be known approximately within some range according to the error margins of the sensors used such as inertial devices. The technique proposed in this chapter is based on detecting junctions in all images using the so-called the JUDOCA operator, and through homographic transformation, correlation is applied to achieve point correspondences. The match set is then triangulated to obtain a set of 3D points. Point clustering is then performed to achieve a bounding box for each obstacle, which may be used for localization purposes by itself. Finally, voxel occupancy scheme is applied to get volumetric representation of the obstacles.
