Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] see figure 1 , the steps in the embodiment include:

[0024] S11: Detect the outline of the human body in each frame of image;

[0025] S12: It is determined that the distance between any two human silhouettes in the image is less than a threshold, and a fallen human silhouette is detected in the image after several frames, then it is determined that a fighting behavior occurs.

[0026] Wherein, the threshold can be set according to the number of horizontal pixels between two people.

[0027] In the method in the embodiment, the fighting process is determined by the distance between any two human body contours and the height of the upper limbs of the human body, and the user does not need to use eyes to detect, reducing the situation that the fighting phenomenon cannot be discovered in time.

[0028] Preferably, see figur...

Abstract

The invention provides a method for detecting fighting behaviors. The method includes: detecting body silhouettes in each frame of images; and if the distance between any two body silhouettes in the images is determined to be smaller than a threshold and fell body silhouettes are detected in the images after a plurality of frames, determining that fighting behaviors occur. Fighting processes are determined by the distances between any two body silhouettes and whether human bodies fall down after a plurality of frames or not, and detection with eyes by a user is not needed, so that the circumstance that fighting phenomena cannot be found timely is reduced.

Description

technical field [0001] The invention relates to the field of security protection, in particular to a method for detecting fighting behavior. Background technique [0002] At present, in the field of security protection, events in the current area are detected by cameras, for example, moving people or animals in the current area are detected. [0003] The existing detection technology can only capture the content of the image, and cannot further analyze the content of the image. When there are people fighting in the image, the user can only determine it by observing and judging with the eyes. If they did not see it at that time, these behaviors will be ignored. Contents of the invention [0004] The present invention aims to provide a method for detecting fighting behavior, so as to solve the problem that the fighting phenomenon in the above images is ignored. [0005] In an embodiment of the present invention, a method for detecting fighting behavior is provided, includi...
