Embodiment Construction

[0046] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0047] The invention provides a method for counting the flow of people at an airport security checkpoint, such as figure 1 shown, including the following steps:

[0048] S1. Collect video of the flow of people through the vertical camera installed on the top of the bayonet.

[0049] By observing a large amount of video data, it is found that when the vertical camera is used to collect the video of the flow of people, the head of the pedestrian will basically not be blocked when the pedestrians approach each other. Therefore, by distinguishing and extracting the head features in the foreground image, the pedestrians can be counted basically accurately.

[0050] S2. Perform preprocessing on the video of the flow of people collected in step S1.

[0051]Judging whether the crowd video collected in step S1 is a color image, such as figure 2 shown, if so,...

Abstract

The invention discloses a method for counting passenger flow at an airport security check counter. The method comprises steps of: converting an image in a video sequence into a grayscale image, extracting a foreground image by a frame difference method and binaryzing the foreground image; extracting a head part from the foreground image by using a head grayscale characteristic and connected domain detection algorithm; in a head tracking and counting algorithm, tracking and counting head characteristics by using the specificity of the head connected domain in videos and a container; and counting the number of people by using the tracking of the head characteristics. The method may automatically count the passenger flow at a place, and can be used at other fixed places similar to the airports and with dense people flow, such as railway stations, bus stations, and tourist resorts.

Description

technical field [0001] The invention belongs to the technical field of control and instrumentation, and in particular relates to the design of a method for counting people at an airport security checkpoint. Background technique [0002] As airports play an increasingly important role in the national economy and production and life of various countries, the safety and operational efficiency of airports have received greater attention. As a "visible" means, video surveillance can intuitively understand the real-time situation of the airport, and has become an indispensable security guarantee for airports of all sizes. In the wide application of airport video surveillance systems, the use of computer image technology to automatically process information in video surveillance and reduce manual participation is the future development direction of video surveillance and data analysis. People counting has a wide range of applications in real life, for example, the statistics of pa...
