Method for detecting state of personnel in swimming pool

Abstract

The invention provides a method for detecting the state of personnel in a swimming pool, which can reduce drowning injury and improve the safety coefficient of the swimming pool. The method comprisesthe steps of acquiring a visible light image training set of a swimming pool, and training a position recognition model based on the acquired training set; capturing a visible light image of the swimming pool in real time, and inputting the visible light image into the trained position recognition model to obtain the position of the person in the pool and a detection frame corresponding to the person in the pool; constructing a decision tree based on an isolated forest by utilizing samples in the training set; based on the constructed decision tree and the obtained detection box correspondingto the personnel in the pool, performing first-level posture classification on the personnel in the pool, including an upright posture and a non-upright posture; and according to the primary posture classification result of the adjacent frames at the same position, determining whether the person in the pool is drowned, and if so, giving an alarm. The invention relates to the field of swimming poolsafety monitoring.

Description

technical field [0001] The invention relates to the field of swimming pool safety monitoring, in particular to a method for detecting the status of people in a swimming pool. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, swimming, a whole-body sports suitable for the masses, is becoming more and more popular. But because swimming is carried out in water, it has certain dangers. Beginners often cause choking and loss of balance because they cannot breathe and move freely in water, and then cause drowning accidents. Sometimes swimmers may also drown due to cramps, collisions, illness or mental stress. [0003] In order to effectively solve the drowning problem, many state monitoring and alarm systems have been proposed at home and abroad. Existing monitoring and alarm systems mainly include methods such as a drowning monitoring system monitored by a lifeguard, a wristband sensor monitoring system,...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for detecting the state of people in a swimming pool, so as to solve the problems in the prior art that the monitoring efficiency of the drowning monitoring system is low, and the wristband sensor monitoring system cannot monitor multiple people at the same time
