Abstract

The invention relates to an intensive pedestrian flow rate real-time detection method based on the color feature. The intensive pedestrian flow rate real-time detection method based on the color feature comprises the following steps: carrying out cluster characteristic analysis on collected hair color picture samples, carrying out preprocessing of distortion correction on videos, carrying out binaryzation according to the color feature, extracting movement foreground according to difference of backgrounds, mixing a binaryzation result and a foreground picture, obtaining an area of heads of pedestrians by analyzing, tracking the pedestrians, recording tracks of the pedestrians, and judging the number of the pedestrians and movement directions according to track information. The intensive pedestrian flow rate real-time detection method based on the color feature can effectively solve the problems of interference of background colors and difficult cutting of foreground of moving targets, is low in computation complexity, can detect the pedestrian flow rate in real time, and is suitable for the field of monitoring of intelligent videos.

Description

technical field [0001] The invention relates to human flow analysis in the technical field of computer vision, in particular to a method for real-time detection of dense human flow based on color features. Background technique [0002] Computer vision is a multidisciplinary technical field, which involves computer, signal processing, mathematics and other disciplines. In the field of computer vision, the direction of human-centered research occupies a large part, such as face recognition, pedestrian tracking, and traffic statistics. With the development of society, people counting in some public places has become an important public safety requirement and an important business requirement. The method of using computer vision to count people has the characteristics of low cost, saving labor costs, and high degree of automation. Therefore, in railway stations, large shopping malls, subway stations, airports and other places, there are many people counting systems based on co...
