Abstract

The invention discloses a thermal power plant on-site safety helmet wearing detection method, which comprises the steps of obtaining historical video pictures with workers in a monitoring area, and forming a safety helmet wearing detection data set; labeling the safety helmet wearing detection data set, and randomly dividing the safety helmet wearing detection data set into a training set and a test set; according to the obtained safety helmet wearing detection data set, generating an anchor frame corresponding to the safety helmet wearing detection data set and suitable for the monitoring area; training the improved YOLOv3 model by using the training set to obtain a helmet wearing detection model; adjusting the model confidence of the helmet wearing detection model; and carrying out real-time detection on the wearing condition of the safety helmet in the monitoring area based on the safety helmet wearing detection model. On the basis of the improved YOLOv3 model, real-time detection of safety helmet wearing of a thermal power plant on site is achieved, the method can adapt to complex scenes on site, mAP of safety helmet wearing detection is improved, the safety awareness of workers can be improved, and safety production on site is helped to be carried out in order.

Description

technical field [0001] The invention belongs to the technical field of intelligent video monitoring safety, and relates to a safety helmet wearing detection method at a thermal power plant site. Background technique [0002] Wearing a hard hat is a measure to prevent brain injury. Studies have shown that nearly 90% of brain injuries in construction sites and inspection sites are caused by not wearing safety helmets correctly. Testing the wearing of safety helmets by relevant personnel can effectively reduce the incidence of related accidents. [0003] In the early days, there were usually dedicated safety supervisors on the construction and inspection sites to test the wearing of helmets by the staff, but this method was difficult to supervise in an all-round way, and the effectiveness of the supervision could not be guaranteed. Therefore, there is a need for a safety helmet wearing detection method that can supervise construction and inspection sites in real time and reduc...
