Embodiment Construction

[0033] In the existing scheme of determining the flow of people based on head detection, a single-class classifier is used, which often leads to missed detection, for example, it is impossible to simultaneously detect dark-colored hair (including wearing a dark-colored hat) and a light-colored human head. Heads with hair (including wearing light-colored hats), in order to solve the problem of incomplete and inaccurate detection at present, the present invention proposes a method for counting the flow of people, please refer to figure 1 , is a flowchart of an embodiment of the present invention, including:

[0034] S101: Use parallel multi-class classifiers to detect heads in 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 specific process of ...

Abstract

The invention discloses a people flow rate statistical method and a system, wherein the method comprises the following steps: adopting parallel-connected classifiers to carry out human head detection on a current image, and 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 people flow rate statistical method and the system can connect a plurality of classifiers in parallel for use and simultaneously detect a plurality of types of human head targets in dark hair, light hair, various colors of hats and the like.

Description

technical field [0001] The invention relates to the technical fields of video monitoring and image processing and analysis, in particular to a method and system for counting people flow. 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 directions by entering / exiting. [0003] In the existi...
