Passenger flow counting device and system

Abstract

The invention provides a passenger flow counting device and system, which relates to an image processing technology and is used for improving the accuracy of passenger flow counting. The passenger flow counting device comprises an image acquisition module, a pedestrian target regional image determination module, a pedestrian target distribution condition determination module, a pedestrian densityand pixel weight determination submodule and a passenger flow people counting module, and is characterized in that the image acquisition module is used for acquiring a current frame image; the pedestrian target regional image determination module is used for determining a pedestrian target regional image corresponding to the current frame image through the current frame image and an acquired background image; the pedestrian target distribution condition determination module is used for training a pedestrian target classifier by HOG features based on sample images, and determining pedestrian target distribution conditions in the current frame image; the pedestrian density and pixel weight determination submodule is used for determining the pedestrian density and pixel weight corresponding to the current frame image based on the pedestrian target distribution conditions; and the passenger flow people counting module is used for determining the number of passenger flow people in the current frame image according to the pedestrian target regional image, the pedestrian density and the pixel weight. The passenger flow counting device and system are mainly applied to passenger flow counting technologies.

Description

technical field [0001] The invention relates to image processing technology, in particular to a passenger flow counting device and system. Background technique [0002] Passenger flow is an important basis for measuring the busyness of public places, and accurate real-time passenger flow statistics have important guiding significance for the management of public places. For example, if you can accurately grasp the real-time passenger flow of subway stations or shopping malls, you can dynamically adjust the number of staff and formulate reasonable marketing strategies. [0003] With the development of information technology, video surveillance has been widely used and is developing in the direction of intelligence and automation. Compared with the way of using manual or video-assisted manual observation to realize passenger flow statistics, passenger flow statistics based on video analysis has great advantages in terms of statistical accuracy and resource consumption.

Problems solved by technology

[0005] However, in the process of realizing the present invention, the inventor found that the passenger flow counting method in the prior art relies on the HOG feature of the video to detect

However, due to the defects of the HOG feature, when the detection environment changes, pedestrians are seriously occluded, and the light conditions are not good, the accuracy of passenger flow statistics using existing technologies will also decrease.
