We present a 3D modeling system for traffic surveillance applications. The application contains several cameras positioned around a traffic scene. The video signals are compressed and streamed to a central client. At the central client a scene reconstruction is carried out, using all 2D camera views utilizing 3D camera calibration information. To combine all views into a 3D model, moving objects are separated from static background first. Then a geometric model is built for the background.
