Abstract

The embodiment of the present invention provides a method and device for detecting that a construction worker is not wearing a helmet based on visual analysis. The second data of the height; compare the first data and the second data to determine the head height comparison model; set the preset video monitoring equipment at the construction site to obtain the construction scene video; determine according to the construction scene video construction personnel image, and obtain the head height data in the construction personnel picture; Substitute the head height data into the head height comparison model to judge whether there are construction personnel who do not wear safety helmets.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and device for detecting that construction personnel are not wearing safety helmets based on visual analysis. Background technique [0002] In the construction site of a construction site, it often occurs that personnel are injured by falling objects during production operations or head injuries caused by personnel falling by themselves. As a kind of personal head protection, safety helmet can effectively prevent and reduce the accidents of operators during production operations. Therefore, when the construction team enters the construction site, the construction personnel will be required to wear safety helmets. However, some construction personnel may not wear safety helmets for various reasons, or may not wear safety helmets to the head position. Therefore, in order to prevent the occurrence of accidents, it becomes extremely important to monitor the wearing...
