摘要：The invention concerns a traffic surveillance system that is used to detect andtrack vehicles in video taken of a road from a low mounted camera. The inventors havediscovered that even in heavily occluded scenes, due to traffic density or the angle of lowmounted cameras capturing the images, at least one horizontal edge of the windshield isleast likely to be occluded for each individual vehicle in the image. Thus, it is an advantageof the invention that the direct detection of a windshield on its own can be used to detecta vehicle in a single image. Multiple models are projected (206) onto an image withreference to different points in the image. The probability of each point forming part of awindshield is determined based on a correlation of the horizontal edges in the image withthe horizontal edges of the windshield model referenced at that point (220). Thisprobability of neighbouring points is used to possible detect a vehicle in the image (224).Aspects of the invention include a method, software and traffic surveillance system.
