Claim One:
1. A people counting system, comprising: a top-view image-capturing device, capturing a top-view image; a first side-view image-capturing device, capturing a first side-view image; a second side-view image-capturing device, capturing a second side-view image; an image stitching module, coupled to the top-view image-capturing device, the first side-view image-capturing device and the second side-view image-capturing device and stitching the top-view image, the first side-view image and the second side-view image into ultra wide-angle image; a region of interest (ROI) selecting module, coupled to the image stitching module and selecting at least one recognition zone and a counting zone from the ultra wide-angle image; a face recognition module, coupled to the ROI selecting module and monitoring the recognition zone to determine a face location corresponding to a face through analyzing the recognition zone; a head recognition module, coupled to the ROI selecting module and monitoring the counting zone to determine a head location corresponding to a head through analyzing the counting zone; an object tracking module, coupled to the face recognition module and the head recognition module, and generating a face track and a head track according to the face location and the head location, respectively; and a people counting module, coupled to the object tracking module and counting a first number of face tracks passing through the counting zone during a time interval, counting a second number of head tracks passing through the counting zone during the time interval and comparing the first number with the second number to generate a people counting result.
