Near-drowning behavior detection method fusing UWB indoor location with video target detection and tracking technology

Abstract

Devices related to a near-drowning behavior detection method fusing UWB indoor location with a video target detection and tracking technology comprise a smart bracelet module, an intelligent monitoring information processing module, a communication module and a display alarm module, the smart bracelet module is used for performing indoor location, the intelligent monitoring information processingmodule is used for processing video data acquired by an intelligent monitoring camera, location information of a smart bracelet and water depth information; and the communication module is used for realizing information transfer among the smart bracelet module, the intelligent monitoring information processing module and the display alarm module. Specific detection steps of the near-drowning behavior detection method are performed according to the following way: performing system initialization; and building a relationship among an image of the intelligent monitoring camera, location of the smart bracelet module and a swimming pool coordinate system, then setting near-drowning conditions, and performing near-drowning determination by virtue of a near-drowning detection algorithm. The near-drowning behavior detection method is simple in main body structure, smart in design concept, good in using effect, high in detection accuracy, low in maintenance cost, friendly in application environment and broad in market prospect.

Description

Technical field: [0001] The invention belongs to the field of computer vision technology and video monitoring, and relates to a swimming pool drowning behavior detection method, in particular to a drowning behavior detection method integrating UWB indoor positioning and video target detection and tracking technology. Background technique: [0002] Swimming pool is the basic construction facility of every city and the main place for people's leisure and entertainment. But swimming also has the risk of drowning. According to statistics, drowning death is the leading cause of accidental death among teenagers in my country. Many drowning incidents occur in public swimming places. Even if there are professional lifeguards supervising, but because the drowning person cannot be found in time, the death incident occurs. Research on automatic detection of drowning behavior has been carried out in foreign countries as early as 20 years ago. In the prior art, some technical solutions...

Problems solved by technology

However, the system also has many disadvantages. For example, the system can only detect the drowning person who has already drowned in the late stage. At this time, the life of the drowning person is already in danger. Not only the maintenance cost is high, but also the accuracy of monitoring is easily disturbed by other objects

The Chinese patent application number 201110448257.X discloses an invention patent named video-based early drowning behavior detection method. The patent discloses a drowning behavior detection method using a hidden Markov model with low maintenance costs , but the pre-training and modeling process of this method is complicated, and the real-time performance is not good in the actual execution process. At the same time, the detection accuracy is not high, and the false detection rate is high.
