Integration of real-time labor positioning data and 3D laser scan model for dangerous zone access monitoring

Ensuring safety at construction sites is imperative to mitigate the risk of unsafe worker behavior. However, conventional worker safety-monitoring practices heavily rely on labor-intensive and error-prone manual methods. To address this challenge, we propose a real-time safety monitoring solution that integrates labor location data with 3D laser scanning data on construction sites. Specifically, our proposal introduces an indoor and outdoor location tracking method tailored for construction sites. We have also developed software that seamlessly integrates with 3D scan data, comprising point cloud information. To assess the feasibility of our safety monitoring system at the site, we conducted a thorough examination of the current safety management practices at an active construction site, analyzing the scenarios associated with managing ongoing risk factors for each process. This study delves into the primary risk factors identified during our fieldwork, presenting three specific application scenarios for the system. As a result, we demonstrate that our proposed system can effectively contribute to safety monitoring in areas such as controlling inadequate aisle use, managing the risk of heavy equipment collisions, implementing access control, and regulating end and aperture access control.
