Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] see figure 1 , the steps in the embodiment include:

[0025] S11: Detect the outline of the human body and the outline of the collar in each frame of image;

[0026] S12: It is determined that the distance between any two human silhouettes in the image is less than the first threshold, then respectively detect the positional relationship between the collar and the head of each person in the image;

[0027] The first threshold can be set according to the number of pixels, and can also be determined according to the ratio, for example, the distance is 1.3-1.7 times the width of the smallest rectangle that frames the outline of the human body. It can prevent false positives and at the same time achieve the best effect of more than 70% correct recognition.

[0028] S13: If the change in the positional relationship between the c...

Abstract

The invention provides a method for detecting a fighting behavior. The method comprises the following steps of detecting a human body contour and a collar contour in each frame image; when determining that the distance between any two human body contours is less than a first threshold value, respectively detecting the position relation between the collar and the head of each person in the image; and when the change of the position relation between the collar and the head of one person is more than the threshold value, determining that the fighting behavior occurs. A fighting process is determined through the distance between any two human body contours and the position relation between the collar and the head of a human body without detecting by the eyes of a user, so that the phenomenon that the fighting behavior cannot be timely found is avoided.

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 his eyes. If he 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, including...
