Embodiment Construction

[0093] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0094] A detection method for corporal punishment of children by preschool teachers, comprising a scene construction step and a video detection step, specifically as follows:

[0095] 1. The scene construction step, its function is to obtain the background model of a certain monitored scene in the kindergarten, and the relationship mapping table between the position and height of the moving foreground block of the kindergarten teacher appearing in the video image of the scene, such as figure 1 shown, including the following steps:

[0096] S0. Establishing a background model is mainly to obtain the video image background of the monitored scene, and as time changes, the video image background of the monitored scene can be adaptively updated to better adapt to various light changes.

[0097] What the present invention adopts is the mixed Gaussian ...

Abstract

The invention provides a method for detecting the behavior of a kindergarten teacher corporally punishing a child, which includes establishing a background model of a monitored scene in a kindergarten; acquiring a position-height mapping table of a moving foreground block of a kindergarten teacher appearing in a video image of the monitored scene; The video image of the monitored scene; obtain all the moving foreground blocks in each frame of video image; detect the starting position of the kindergarten teacher; obtain the tracking list of the kindergarten teacher and the child tracking list; judge whether the kindergarten teacher is bent; Approach the child; obtain the intensity of the movement of the kindergarten teacher's limbs; judge whether the teacher is abusing the child. The invention adopts a fully automatic analysis algorithm to obtain the actions and behaviors of the kindergarten teachers and children in the video scene, without additional manual assistance, and the application is more convenient; it integrates a variety of behavioral criteria to comprehensively determine the behavior of the kindergarten teachers corporally punishing children, and the detection results are more accurate. Fewer false detections and missed detections; it has the advantages of wide environmental adaptability and fast algorithm speed.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a method for detecting corporal punishment of children by kindergarten teachers. Background technique [0002] Kindergarten is a place for childcare and basic education for children aged 3 to 6. It can not only help children spend their childhood healthily and happily, but also allow them to be exposed to collective life from an early age, and initially form a complete and healthy personality and good behavior habits. , Basic natural and social knowledge will play a very important role in future growth.
