Building 3D models of vehicles for computer vision

Abstract

We present a technique to build and manipulate three dimensional models of vehicles, to be used by a computer vision system. These tools will help find a suitable class of models for the vehicles and the trajectories, which are restricted to shape of cars (symmetry, regularity) and their trajectories (ground plane constraint), moving on a fixed scenario. The models consist of a variable number of facets in the three dimensional space, varying along time, each one with a corresponding objective (evaluation) function.
