Abstract

The embodiment of the invention provides a drowning behavior identification method, a monitoring camera and a monitoring system, and the method comprises the following steps: collecting a plurality offrames of images in a monitoring water area; inputting a single-frame image in the multiple frames of images into a preset deep neural network model, obtaining the drowning confidence of each human body target in the single-frame image, wherein the preset deep neural network model is a deep neural network model obtained by training in advance according to a sample image containing the key point position information of the human body target collected from the upper part of the water area when the human body target is drowned; and for each human body target, identifying whether the human body target has a drowning behavior or not according to the drowning confidence of the human body target. Through the scheme, the drowning behavior recognition precision can be improved.

Description

technical field [0001] The present application relates to the technical field of intelligent monitoring, in particular to a drowning behavior recognition method, a monitoring camera and a monitoring system. Background technique [0002] Swimming, as an excellent exercise for relaxing nerves and exercising cardiopulmonary function, has always been the first choice for people to exercise. However, there is a certain danger of drowning when people swim, and the process of drowning is very fast, and death can be caused by the arrest of breathing and heartbeat in 4 to 7 minutes. [0003] In order to cope with the occurrence of drowning, multiple lifeguards are arranged around the water area. The lifeguards always observe the situation of swimmers in the water area. Once they find someone drowning, they will immediately rescue them. However, due to the large number of swimmers in the water area, manual monitoring will inevitably be neglected, resulting in low monitoring efficienc...
