Marine engineer abnormal behavior recognition method based on human body joint point detection and D-GRU network

Abstract

The invention provides a marine engineer abnormal behavior recognition method based on human body joint point detection and a D-GRU network. The method comprises the steps of designing a human body detection model based on human body joint point detection and a GRU network structure; due to the fact that a cabin is dark in light and complex in working environment, detecting and tracking human body joint points by the model through a joint point detection model, and detecting the abnormal behavior of the marine engineer by the human body joint point detection model; and outputting coordinates of the obtained heat maps of the key points, and inputting the coordinates into a D-GRU network structure to carry out human body posture prediction so as to realize recognition of abnormal behaviors of marine engineers. According to the technical scheme, the problem that in the prior art, when working personnel such as marine engineers work in far places such as ship buildings, engine rooms and boiler rooms, the personal safety of the marine engineers cannot be known and reflected in time is solved.

Description

technical field [0001] The present invention relates to the technical field of marine automation and intelligence, in particular, to a method for identifying abnormal behavior of marine engineers based on human body joint detection and improved D-GRU network structure. Background technique [0002] In Hyundai Engineering 2009 Regulations on Alarms and Indicators Regulation 8: Personnel alarms should be capable of automatically sounding the alarm on the flybridge or at the officer's quarters and if not reset from the machinery space within a period of time normally not exceeding 30 minutes. However, a pre-warning signal should be given before an alarm is sent to the bridge or the residence of the officials. Under what circumstances does the personnel alarm operate? The rules say that when there is an alarm in the engine room, it will be automatically activated when the liner crew goes to the engine room, or manually activated when the liner crew goes to the routine inspection...
