: Recognizes if a worker is facing away or kneeling, which increases risk.
: The study noted that moving machine parts (like an excavator's arm) can sometimes obstruct the view or cause perspective distortion, leading to slight distance errors. 999 Part 1(1).mp4
: Scenarios were built in Unity 3D to mimic real-world construction tasks, such as collaborative excavation. : Recognizes if a worker is facing away
: Distinguishes between workers, excavators, and forklifts. 999 Part 1(1).mp4
: The system significantly decreased the number of "nuisance" alarms compared to static sensors, as it understands when a worker or another machine is approaching safely for collaboration.
