Embodiment Construction

[0023] In order to further understand the content of the present invention, in conjunction with the attached figure 1 And embodiment describe the present invention in detail.

[0024] combined with figure 1 , the detection method of abnormal gathering behavior in the bus that the present invention proposes comprises the following steps:

[0025] S1: Arrange infrared cameras for shooting video at multiple positions in the bus;

[0026] S2: Use the infrared camera in the bus in S1 to obtain the video segment in the bus, and perform video frame image preprocessing on the acquired video segment, and convert the video frame image into a data set;

[0027] S3: Perform affine transformation processing on the video frame images in S2, model the internal structure of the bus, and divide the internal space of the bus into four spaces: front, rear, left and right;

[0028] S4: Use the yolov5-s algorithm to train the head target detection algorithm on the data set in S2, and encode and...

Abstract

The invention relates to a system for detecting abnormal gathering behaviors in a bus. The system comprises a video acquisition module, a video analysis module, an abnormality judgment module and an abnormality alarm module, wherein the video acquisition module acquires video data in a bus, preprocesses the video data and models the internal space of the bus; the video analysis module is used forcarrying out coding identification on a head in a video in the bus; the abnormality judgment module calculates an abnormality judgment index, calculates a comprehensive weight according to the abnormality judgment index, and further judges whether the abnormality exists or not; if it is judged that the abnormal alarm module is abnormal, an alarm is given; wherein the video acquisition module is electrically connected with the video analysis module, the video analysis module is electrically connected with the exception judgment module, and the exception judgment module is electrically connectedwith the exception alarm module. Aiming at the problem that the detection algorithm in the bus lacks consideration of the actual background of the bus, the method practically considers the actual scene in the bus and accurately judges the abnormal gathering behavior.

Description

technical field [0001] The invention relates to a detection system for abnormal gathering behavior in a bus. Background technique [0002] In recent years, the state has vigorously advocated green transportation, making public travel the first choice for many citizens. As the most common green travel mode, buses are not only convenient, but also have the characteristics of large passenger flow, high density, and complex crowds. They are high-incidence scenarios for group incidents. At the same time, because of its relative closure and lack of other security monitoring methods, the danger of mass incidents is more prominent. [0003] In traditional research, only attention is paid to the use of surveillance video for scheduling drivers to get on and off or to track the location of criminals. The abnormal behavior of passengers has not received widespread attention. Due to the strong group influence in the bus, the detection of abnormal gathering behavior can prevent major ...
