System and method for detecting pedestrians

摘要

A method is provided for detecting a pedestrian exterior to a vehicle by use of a vehicle-mounted image-based monitoring system. An edge-based pedestrian detection analysis is applied to the input image data to determine an edge-based confidence value of a candidate image area being a pedestrian. A motion-based pedestrian detection analysis is applied to the input image data to determine a motion-based confidence value of a candidate image area being a pedestrian. A final confidence value is obtained by combining the edge-based confidence value and motion-based confidence value using weighting factors that are functions of vehicle speed. The final confidence value is compared to a threshold value for determining whether to generate a warning that a pedestrian may be present in the input image data.
