Abstract

The method for identifying unsafe behaviors of underground personnel in coal mines based on human body posture estimation of the present invention is aimed at the current human-centered video monitoring mode for the monitoring of unsafe behaviors of underground personnel, which has limited manual monitoring duration, difficulty in simultaneous monitoring of multiple scenes, and manual monitoring. In order to solve problems such as untimely processing of the results, intelligent analysis technology was introduced into the coal mine video surveillance system, and the posture information of coal mine personnel was extracted by mining Hourglass Networks with Hard Mining based on difficult samples based on generative confrontation training. Then, according to the trajectory of the extracted human body posture information in the surveillance video, it can be judged whether the behavior of the underground personnel in the coal mine is abnormal, and the alarm prompt can be accurately detected to prevent problems before they happen and ensure the safety of coal mine production.

Description

technical field

[0001] The invention relates to coal mine safety monitoring technology, in particular to a method for identifying unsafe behaviors of coal mine underground personnel based on human body posture estimation. Background technique

[0002] my country is the largest coal producer and consumer in the world, and the continuous, healthy and stable development of the coal industry has a huge impact on the healthy operation of the national economy. Underground coal mines have harsh working conditions, complex environments, and accidents. The analysis and research on the causes of a large number of accidents in coal mines in my country found that more than 80% of coal mine accidents originated from the unsafe behavior of underground personnel. Therefore, how to effectively extract the behavior information of underground personnel from the coal mine surveillance video is of great significance to ensure the safety of coal mine production.
