Swimming pool anti-drowning supervision method, device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a swimming pool anti-drowning supervision method, device, computer equipment and storage medium. The method includes: acquiring images taken by a plurality of cameras; inputting the images into a target detection model to detect human bodies and human heads, so as to obtain human body target detection frames in a swimming pool and human head target detection frames in a swimming pool; Calculate the relationship between the human head and the human body in the target detection frame; perform multi-camera fusion on the human body target detection frame in the swimming pool and the human head target detection frame in the swimming pool to obtain the human body frame and head frame; determine the relative positional relationship between the human body and the human head and the water surface; calculate the current time The association between the bounding box sequence of the current moment and the bounding box sequence of the previous moment to obtain the human body tracking trajectory; update the state database; generate warning information according to the state database. By implementing the method of the embodiment of the present invention, the automatic monitoring of the target human body in the swimming pool can be realized, and the accuracy of drowning prevention monitoring can be improved.

Description

technical field [0001] The present invention relates to an anti-drowning supervision method, more specifically to a swimming pool anti-drowning supervision method, device, computer equipment and storage medium. Background technique [0002] With the development of sports, people's enthusiasm for participating in sports is increasing, but swimming, 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, making them the number one cause of death among teenagers, and China's drowning death rate is the highest in the world.

Problems solved by technology

[0003] When the swimming pool is supervised against drowning, it will involve target detection, and the main background of the target detection problem is water. When swimmers exercise, the water in the pool will fluctuate; sunlight and lights will produce reflections on the water surface. It is difficult to remove by pretreatment technology. In addition, the location of the reflection will continue to change with the fluctuation of the water surface; swimmers have a wide range of ages, and people on the shore of the pool and in the pool will have various actions and behaviors. The part below the water surface is affected by the refraction, turbidity and fluctuation of the water, and it is difficult to observe; there will be various facilities and sundries on the shore of the swimming pool, such as stands, life-saving equipment, training equipment, and swimmers’ personal belongings, etc., as well as in the swimming pool. Various floats such as lane lines and training equipment

[0004] At present, the operation mode of most swimming pools is based on the traditional manual mode of operation, which has high costs and incomplete supervision. The existing technology installs underwater cameras around and at the bottom of the swimming pool, and uses algorithms to judge whether swimmers are swimming normally. Or in a state of drowning and struggling, and can only detect and identify the human body for anti-drowning, but the accuracy of this method is not high, and it cannot improve the accuracy of anti-drowning supervision
