System and method of alerting a driver that visual perception of pedestrian may be difficult

摘要

A pedestrian perception alert system configured to issue a warning during real-time when a driver's visual detection of a pedestrian is difficult, and a method thereof is provided. The system includes a video camera, an alert for issuing a warning, a processor, and a Pedestrian Detection Unit ("PDU"). The PDU analyzes the video camera image to detect a pedestrian. A Global Clutter Analysis Unit ("GCAU") generates a global clutter score. A Local Pedestrian Clutter Analysis Unit ("LPCAU") generates a local pedestrian clutter score. The processer processes the global clutter score and local pedestrian clutter score so as to generate a pedestrian detection score. The alert is actuated when the pedestrian detection score is outside of a predetermined threshold so as to notify the driver that perception of a pedestrian is difficult at that time.
