AI Technical Summary
Existing technologies struggle to accurately identify whether construction workers are wearing safety helmets in complex lighting environments or when visibility is obstructed. Furthermore, the lack of spatial positioning mapping to the real environment leads to the risk of misjudgment or omission, affecting the timeliness and effectiveness of safety monitoring at construction sites.
By combining visible light and thermal infrared video streams, spatial mapping is established with BIM data through coordinate alignment to locate the head area of construction workers, extract the thermal infrared head temperature distribution, calculate the individual thermodynamic deviation, determine the wearing status, and generate dynamic alarm values based on risk level weights to record violations.
It has achieved stable determination of the helmet wearing status of construction workers in different environments, improved the accuracy and real-time nature of violations, and enhanced the precision and response efficiency of on-site safety supervision.
