Safety Helmet Wearing Detection in Aerial Images Using Improved YOLOv4

Abstract: In construction, it is important to check whether workers wear safety helmets in real time. We proposed using an unmanned aerial vehicle (UAV) to monitor construction workers in real time. As the small target of aerial photography poses challenges to safety-helmet-wearing detection, we proposed an improved YOLOv4 model to detect the helmet-wearing condition in aerial photography: (1) By increasing the dimension of the effective feature layer of the backbone network, the model's receptive field is reduced, and … Show more

“…The convolutional block attention module (CBAM) attention mechanism is also used to make the model focus more on the main information to improve detection accuracy. Due to the small target size and the loss of safety helmet feature information brought on by network downsampling, Chen et al 29 proposed an improved YOLOv4 model to detect the wearing of safety helmets in aerial photography. Deep learning-based object detection has become a mainstream algorithm, surpassing traditional image processing algorithms in speed and accuracy.…”

“…Considers the edge attributes by using top-k attention mechanisms to learn hidden semantic contextual, improved network performance. Chen et al [24] presented an improved YOLOv4 algorithm, which increases the dimension of the effective feature layer of the backbone network. It introduces the cross stage partial (CSP) structure into path aggregation network (PANet).…”
