Abstract

The invention relates to the technical field of computer vision, and discloses a binocular stereoscopic vision based head detecting and counting method which solves a problem that a head detecting and counting scheme in the traditional technology is high in calculation amount, inaccurate in counting and low in accuracy. The method disclosed by the invention comprises the steps of a, calibrating a binocular image acquisition system; b, performing monitoring region image acquisition by using the calibrated binocular image acquisition system, and acquiring a passenger flow scene image; c, performing preprocessing on the acquired passenger flow scene image; d, acquiring a depth image of the image; e, detecting heads with different depths in the depth image by using a contour line searching method; f, tracking the detected heads; g, detecting new heads in a new video frame, and updating the number of heads; and h, outputting the current number of heads. The method disclosed by the invention is applicable to head detecting and counting for 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 ...
