Image-based construction hazard avoidance system using augmented reality in wearable device

Kim, Kinam / Kim, Hongjo / Kim, Hyoungkwan

AbstractConstruction sites are inherently dynamic due to continuous resource changes. As construction projects become bigger and more complex, this dynamism can lead to more frequent incidents on jobsites. Safety training, personal protective equipment, and regulations have been applied to improve the safety of construction sites. However, because of the dynamic and congested nature of construction sites, these practices still cannot guarantee safety. This paper proposes a vision-based hazard avoidance system that proactively informs workers of potentially dangerous situations. The system enables workers to recognize and consequently avoid dangers before accidents occur by displaying augmented hazard information on a wearable device. The system comprises of three modules; a vision-based site monitoring module that utilizes image capture device and wearable devices to identify site hazards, a safety assessment module that uses captured image data and fuzzy-based reasoning to evaluate the safety level of each object, and a visualization module that provides actionable information such as hazard orientation, distance, and safety level. The safety information provided by the proposed system can mitigate hazards and improve construction site safety.

Highlights•The proposed system provides customized safety information for individual workers.•The worker with a wearable device was identified using global and user view images.•Hazardous context of an individual worker was visualized on the wearable device.•A worker can obtain hazard information without any operational control.
