Intelligent beach safety protection method and system based on machine vision

Abstract

The invention discloses an intelligent beach safety protection method and system based on machine vision, and the method comprises the steps: controlling a camera to carry out the image collection of a beach according to a preset time interval, and obtaining a beach image; inputting the obtained beach picture into a tide analysis model to obtain the tidal condition of the beach; dividing the beach into a risk area and a non-risk area according to the tidal condition of the beach and the current beach picture; distributing monitoring resources of the camera to the risk area and the non-risk area according to a preset proportion; the monitoring resources obtained in the risk area are larger than the monitoring resources obtained in the non-risk area; after the monitoring resources are distributed, tourist identification is carried out on beach pictures collected by a camera, and tourist behaviors are obtained; inputting the tourist behavior into a risk behavior recognition model to judge whether the tourist behavior belongs to a risk behavior; and giving an alarm prompt in response to the tourist behavior belonging to the risk behavior. The risk behavior identification accuracy and the safety protection efficiency are improved, and the life safety of tourists is guaranteed.

Description

technical field [0001] The invention relates to the field of beach safety protection, in particular to an intelligent beach safety protection method and system based on machine vision. Background technique [0002] The traditional beach security system mainly relies on manual uninterrupted guarding in front of the surveillance camera screen, and monitors risky behaviors of tourists by scanning the screen with human eyes, such as staying on dangerous reefs, going into the sea without wearing a swimming ring, floating in deep sea areas, etc. Different from accidents on land, the golden time of first aid at sea is only a few minutes, and fast maneuvering becomes particularly important. However, long-term manual monitoring can easily cause visual fatigue to the staff, and it is difficult to respond immediately when an unexpected situation occurs, which in turn causes the problem of low safety protection efficiency. On the other hand, due to the limitation of human eyes, it is e...

Problems solved by technology

However, long-term manual monitoring can easily cause visual fatigue to the staff, and it is difficult to respond immediately when an unexpected situation occurs, which in turn causes the problem of low safety protection efficiency.

On the other hand, due to the limitation of human eyes, it is easy to ignore some tourists with risky behaviors due to the limitation of human eyes, resulting in low accuracy of risky behavior identification
