Problems solved by technology

However, in actual monitoring applications, due to conditions such as light source changes, background object movement, occlusion, and poor image resolution, it is often impossible to obtain a complete subject, resulting in the inability to correctly analyze behavior patterns.
In addition, in the part of behavior definition, because fighting behavior may be composed of two or more people, there are many types of fighting behavior and complex, and it is quite difficult to completely define one by one

Embodiment Construction

[0031] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

[0032] refer to figure 1 , the behavior fight detection monitoring system 10 of the present invention is used to monitor an area, and its preferred embodiment includes an image capture device 12, an image processing module 14, a foreground recording module 16, a threshold judgment module 20 and an event Warning module 32 .

[0033] The image capturing device 12 is used for continuously capturing images in the monitoring area. The image processing module 14 is coupled to the image capture device 12 for processing the continuous images to segment a dynamic subject.

[0034] The image processing module 14 uses the temporal differencing method (Temporal differencing) to segment the dynamic subject, and the temporal differencing method is defined as follows:...

Abstract

The invention provides a system for automatically detecting a fight behavior. A method for detecting and monitoring the fight behavior comprises the following steps of: retrieving a plurality of continuously monitored images; processing the plurality of images and partitioning a dynamic main body; generating a movement historical image to acquire a short-time dynamic progress of the dynamic main body; judging whether a value acquired by the movement historical image and a preset threshold value are comprised in a preset monitoring behavior event; and triggering when the preset monitoring behavior event reaches the threshold value, and sending a warning reaction situation out. By the system, the characteristic of the fight behavior is analyzed from a macroscopic angle without pre-establishing a background; therefore, a camera with lower resolution can be used for accurate detection; and a detected result cannot be influenced by the change of light sources.

Description

technical field [0001] The present invention relates to a method for detecting and monitoring fighting behavior, especially a method using macroscopic analysis. The present invention does not need to establish a background in advance and can be accurate regardless of the environment with large changes in light sources or low image quality. detection of fighting behavior. Background technique [0002] In the traditional security monitoring system, the monitoring personnel observe the abnormality in front of the monitoring screen for a long time, and respond to the abnormal situation in real time. This monitoring mode is time-consuming and labor-intensive. In a large-scale monitoring system, it is necessary to hire enough monitoring personnel to monitor many monitoring images at the same time. Occasionally missing important screens. Therefore, the traditional security monitoring system often provides video data to assist in the analysis of the incident after the incident occ...
