Detection of Street-parking Vehicles Using Line Scan Camera

Vehicles parked on streets make traffic problems in urban areas worse. We propose a method to detect those street-parking vehicles, using epipolar plane images (EPIs) acquired by a line scan camera, for traffic census. Our method is based on calculating the distance between the vehicles and the camera from the slope of the feature paths in an EPI. The feature paths are extracted in an EPI by the Hough transformation. The experimental results show that our proposed method can detect vehicles almost at 70 % rate of detection.
