Embodiment Construction

[0032] The present invention proposes a method for counting people flow applicable to multi-angle application scenarios, please refer to figure 1 , is a flowchart of an embodiment of the present invention, including:

[0033] S100: Perform scene calibration on the detection area in the image, so as to divide the detection area into several sub-areas;

[0034] S101: In the sub-region, use a classifier to perform head detection on the current image, and determine each head in the current image;

[0035] S102: Track the determined heads to form a head target movement trajectory;

[0036] S103: Counting the flow of people according to the direction of the moving track of the head target.

[0037] Among them, the scene calibration of the detection area in the image includes: selecting the calibration frame; calculating the scene depth variation coefficient; calculating the size variation range of the head target in the detection area; dividing the detection area into several sub-...

Abstract

The invention discloses a people flow rate statistical method and a system applicable to multi-angle application scenes, wherein the method comprises the following steps: carrying out scene calibration on a detection region in an image and further dividing the detection region into a plurality of sub-regions; adopting a classifier to carry out human head detection on the current image in the sub-regions, determining all human heads in the current image; tracking all the determined human heads, and forming a motion trajectory of human head targets; and carrying out people flow rate counting in the direction of the motion trajectory of the human head targets. Therefore, the method and the system can realize the self-adaptation to various angles of a camera and expand the range of applications through the scene calibration and the automatic selection of the size of a detection window before the detection.

Description

technical field [0001] The present invention relates to the technical field of video monitoring and image processing and analysis, in particular to a method and system for counting people flow applicable to multi-angle application scenarios. Background technique [0002] With the continuous progress of society, the application range of video surveillance system is getting wider and wider. Surveillance cameras are often installed at the entrances and exits of places such as supermarkets, shopping malls, gymnasiums, and airport stations, so that security personnel and managers can monitor the entrances and exits of these places. On the other hand, the flow of people entering and leaving places such as supermarkets, shopping malls, gymnasiums, and airport stations is of great significance to the operators or managers of the above places. Among them, the flow of people refers to the number of people flowing in a certain direction. Refers to the number of people flowing in both ...
