Swimming pool anti-drowning early warning system based on computer vision

Abstract

The invention discloses a swimming pool anti-drowning early warning system based on computer vision. The system comprises the following steps of S1, collecting the motion data of a swimming pool person through a high-definition camera, and transmitting a collected video data stream to a common-performance host through an rtsp protocol, S2, converting each frame of video image into an RGB image, and preprocessing the obtained image by using an image distortion algorithm, and S3, carrying out target detection on the swimmer in the video image by using a pre-trained Yolov3 model. According to theswimming pool anti-drowning early warning system based on computer vision, full-coverage monitoring is conducted on the swimming pool through the camera, the system automatically recognizes swimmersin the swimming pool through the target detection technology based on deep learning, and wearable devices such as bracelets are not needed any more; coordinates of skeleton key points of a human bodyare recognized by utilizing a human body skeleton posture recognition algorithm based on deep learning to judge the posture of the human body, so that the situation that the human body stands in a swimming pool is eliminated, and the system false alarm rate is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-drowning early warning systems, in particular to a computer vision-based anti-drowning early warning system for swimming pools. Background technique [0002] Swimming is a high-risk sport. A large number of drowning incidents occur in swimming pools every year, and most of the deaths due to drowning are due to failure to receive distress calls for drowning in time. With the advancement of image recognition technology and the popularity of surveillance cameras, people are increasingly hoping to monitor drowning events through surveillance equipment, so as to issue warning signals in advance and reduce casualties. [0003] In the existing ones, special surveillance personnel sit in front of the monitoring screen to monitor the swimming pool or lifeguards sit by the swimming pool to observe with the naked eye. However, due to human negligence and the reflection of the water surface of the swimming pool,...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a swimming pool anti-drowning early warning system based on computer vision, to solve the existing problems in the above-mentioned background technology, generally by special monitors sitting in front of the monitoring screen to monitor the swimming pool or lifeguards sitting by the swimming pool visual inspection

However, due to human negligence and the reflection of the water surface in the swimming pool, it is difficult for the monitors to detect the drowning situation of swimmers in time. When the drowning situation occurs, the best rescue time may have been missed.
