# Volumetric Model and 3D-Trajectory of a Moving Car Derived from Monocular TV-Frame Sequence of a Street Scene

## Abstract

A polyhedral approximation for the volumetric description of a moving rigid object from a real-world scene is derived, based on measurements in monocular TV-frame sequences. The trajectory and attitude of the object motion relative to the camera is simultaneously determined up to the same factor which scales the object description. Results from one street scene sequence are presented. The approach is compared to related ones reported in the recent literature.
