Abstract

The invention relates to the technical field of computer vision, which discloses a head detection and counting method based on binocular stereo vision, which solves the problems of large amount of calculation, inaccurate counting and low precision in the head detection and counting scheme in the traditional technology. The method includes: step a. calibrating the binocular image acquisition system; step b. using the calibrated binocular image acquisition system to collect images in the monitoring area to acquire passenger flow scene images; step c. preprocessing the acquired passenger flow scene images; Step d. Obtain the depth map of the image; Step e. Utilize the contour search method to detect the heads of different depths in the depth map; Step f. Track the detected heads; Step g. Detect new heads in the new video frame, And update the number of heads; Step h. Output the current number of heads. The invention is suitable for head detection and counting in passenger flow scenes.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a head detection and counting method based on binocular stereo vision. Background technique [0002] With the growth of population and the frequent travel of people, a huge number of people are surging in various transportation systems, venues, shopping malls, exhibition halls, airport terminals and other places. Whether it is from a commercial or security point of view, The work of counting people is very important. However, manual counting is a very difficult thing, and it is impossible to manually count the passenger flow of these large-scale human flow places. Therefore, the research on automatic people counting has great significance. [0003] The automatic people counting methods that have been proposed so far mainly include methods based on active infrared sensing, passive infrared sensing, pedal pressure sensing, and video image processing. Based on the active ...
