Detection of street-parking vehicles using line scan camera and scanning laser range sensor

Street-parking vehicles in urban areas are causing various traffic problems, however, have been counted manually in the traffic census, including counting error. We propose two auto-detection methods; one is based on an epipolar-plane image analysis, using a line-scan camera, and the other is based on three-dimensional restoration, using a scanning laser range sensor. Both methods achieve high detection rate. Furthermore, we introduce two-type panoramic street images, obtained by vertically line-scanning camera and laser sensors. Street-parking vehicles side-images will be extracted from the panoramic street images.
