Shooting network-based method and system for warning of drowning prevention in swimming pool

Abstract

The invention relates to a shooting network-based method and system for warning of drowning prevention in a swimming pool. A fixed water camera is installed above a water surface of a swimming pool and a rotatable underwater camera is installed under the water surface of the swimming pool; the water camera and the underwater camera output signals to connect a PC machine or a DSP and a PC machine by video acquisition cards at all paths; the PC machine or the DSP output a control signal to connect an alarm and a stepper motor that controls a cloud platform to make rotations. Besides, the PC machine or the PC machine and the DSP includes/include a spray detection module, a coordinated control module, an underwater drowning determination module and an alarm positioning module. According to the invention, omnibearing and multi-angle warning coverage on a swimming pool can be realized. When a swimmer is drown, the system carries out intelligent determination and emits alarming; and an object position can be provided, so that a lifeguard is warned to carry out rescue at the first time to ensure personal safety of the swimmer.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, in particular to a swimming pool anti-drowning early warning method and system based on a camera network. Background technique [0002] In recent years, swimming, a full-body sport suitable for the general public, has become more and more popular. However, swimmers may drown due to reasons such as beginners, cramps, and disease attacks. Therefore, safety and lifesaving are the most important aspects of swimming. prerequisites. [0003] Existing swimming pool anti-drowning measures are far from perfect, mainly in the following ways: [0004] 1. On-site observation by lifeguards: Due to the limitation of human physiological conditions, monitoring personnel will be negligent due to fatigue and lack of concentration, and it is not easy for lifeguards to observe the situation in deep water with naked eyes. Therefore, the rescue efficiency is low. Even so, the vast majority of swimming pools...

Problems solved by technology

[0005] 2. Infrared detection: Use infrared tubes to detect falling into the water. This kind of equipment can only judge whether someone has fallen into the water, and is not suitable for swimming pool lifesaving

[0006] 3. Sonar detection: The installation and use of this device are expensive, and there are obvious defects, that is, when the lungs of the drowning person are filled with water, sonar cannot detect it, and the system reliability is poor

This method can realize drowning alarm, but it takes a long time to realize the alarm, usually in the late stage of drowning, the risk is relatively high, and it is still unsafe
