Abstract
The disclosure provides a pedestrian head identification method and a pedestrian head identification system. The method comprises the following steps of: S: collecting a depth image of a target region, and extracting a foreground image from the depth image; S: extracting all Regions of Interest (ROI) from the foreground image; and S: constructing concentric circles with each pixel point in each ROI region as a center to calculate a probability that the current pixel point belongs to the pixel points in a head region, obtaining the probability value of each pixel point in each ROI region, comparing the probability value of each pixel point in each ROI region with a preset first threshold, and filtering the pixel points with the probability value smaller than the first threshold, wherein the rest pixel points existent in regional form are points of the head region, and each region is an identified head.
