复杂姿态下的安全帽佩戴检测方法研究

Research on Detection Method of HelmetWearing in Complex Posture

在施工人员复杂姿态下,现有安全帽佩戴检测方法存在检测难度大,精度不高的问题,提出一种基于头部识别的安全帽佩戴检测方法。通过肤色特征识别和头部检测获取头部区域,并进行交叉验证确定头部区域,使用YOLOv4目标检测网络识别安全帽,通过安全帽区域与头部区域的位置关系判断安全帽佩戴情况。最后,通过实验对比分析其他安全帽佩戴检测方法的性能,对安全帽佩戴检测方法进行总结并提出展望。

Existing helmet wearing detection methods have the problems of high detection difficulty and low accuracy in the case of complicated postures for construction workers.A helmet wearing detection method is proposed based on head recognition.Firstly,the head area is obtained through skin color feature recognition and head detection,which performs cross-validation to determine the head area.Secondly,YOLOv4 target detection network is adopted to identify the helmet and determine the positional relationship between the helmet area and the head area.Finally,the performance of other hel-met wearing detection methods is analyzed through experiments,the helmet wearing detection methods are summarized and prospects are proposed.
