ABSTRACT

More than 50% of safety accidents at work sites, by the statistics of accident situations in the industry, have been caused by falling off and falling down. Accordingly, it is required to wear a safety helmet to prevent head injury. Currently, a system in which work supervisors patrol the site and check whether the helmet is worn and the safety situation is being implemented. However, it is difficult to continuously supervise work. In order to prevent safety accidents, it is necessary to establish an automatic management and supervision system by system for wearing personal protective equipment at the work site. Also a system is required to generate warning signals. In this study, a safety helmet-wearing detection system was developed by porting an artificial intelligence model to Raspberry Pi. A model was constructed to detect whether or not a helmet was worn using object detection computer vision technology. The system generates a warning sound when not wearing a helmet is detected. The system was mounted on a mobile body and analyzed images. The detection accuracy was achieved 87%, and through the process of converting to TensorFlow lite file, fps performance improved by 20% compared to the existing TensorFlow model.
