Distance estimate of a pedestrian by an imaging system embedded in a motor vehicle

摘要

The present invention relates to a system for estimating a distance at which is located a pedestrian with respect to a motor vehicle, from the processing of images sensed by a camera on board, said system comprising a first detector (5) for recognizing shapes by learning is capable of delivering, from an image captured, at least one first bounding box (52) representative of a detection of a pedestrian to a first scale of the image, and the estimation means adapted to estimate the distance between the pedestrian detected from the position of a lower limit (53) of the first bounding box (52). The system is characterized in that it further comprises a second detector (6) for recognizing shapes by learning is capable of delivering, from the picture zone delimited by the first bounding box (52), a plurality of second boxes that cover (62r, 62l) representative of the detection of the feet, and means for modifying the position of the lower limit (53) of the first bounding box in order to correspond to an estimated vertical position of said plurality of second boxes that cover (62r, 62l).
