Swimming pool drowning prevention head position judgment method and device, computer equipment and storage medium thereof

Abstract

The embodiment of the invention discloses a swimming pool drowning prevention head position judgment method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring images shot by a plurality of cameras; preprocessing the image to obtain a processing result; performing head target detection on the processing result to obtain head frames under different cameras; performing multi-camera head position matching according to the head frames under different cameras in combination with a multi-camera space fusion technology to obtain a head space position; calculating the distance from the head space position to the horizontal plane and the direction of the normal vector of the horizontal plane to obtain a calculation result; and determining the relationship between the head position and the water surface according to the calculation result. By implementing the method provided by the embodiment of the invention, the position relationship between the head of the swimming pool human body and the water surface can be automatically supervised, and the supervision efficiency and the anti-drowning supervision accuracy are improved.

Description

technical field [0001] The present invention relates to an anti-drowning supervision method, more specifically, a method, a device, a computer device and a storage medium thereof for judging the head position of a swimming pool anti-drowning person. Background technique [0002] With the development of the sports industry, people's enthusiasm for participating in sports activities is also increasing, but swimming, which is one of the popular sports, has become the sport with the highest incidence of safety accidents. According to incomplete statistics released by the Ministry of Health, about 57,000 people die in drowning accidents in my country every year, of which 56.04% are teenagers, becoming the number one cause of death among teenagers, and China's drowning death rate is the highest in the world. [0003] In the anti-drowning monitoring process of the swimming pool, it is necessary to track the human body target in the swimming pool to ensure the safety of the human bo...

Problems solved by technology

[0003] In the anti-drowning monitoring process of the swimming pool, it is necessary to track the human body target in the swimming pool to ensure the safety of the human body target in the swimming pool. Most of the existing technologies use lifeguards at high places to look down to determine whether the head belongs to the water surface or below the water surface. However, this method has the problems of low efficiency and low accuracy, which in turn affects the accuracy of drowning supervision
