Abstract
A system for 3D reconstruction of traffic scenes is presented. Traffic surveillance is a challenging scenario for 3D reconstruction, since only a small number of views is usually available that do not contain much overlap. We address the possibilities and restrictions for modeling such scenarios with only a few cameras, introduce a compositor that allows rendering of the semi automatically generated 3D scenes and discuss problems that need to be considered. Although some cameras might show a common background area, they might still differ drastically in lighting effects. For foreground objects nearly no common visual information might be available, as angles between cameras may be more than 90°. For video transmission, a system is presented which combines MPEG-4 video coding with streaming protocols like RTSP and RTP.
