999 Part 1(1).mp4 [ 2025 ]

: Scenarios were built in Unity 3D to mimic real-world construction tasks, such as collaborative excavation.

The video is part of a study that addresses the high rate of accidents in the construction industry. Unlike traditional sensors that fire an alarm whenever any object is near, DCAS uses a to evaluate risk dynamically based on: 999 Part 1(1).mp4

: By using the known size of objects and camera focal lengths, the system can estimate the distance of a worker or machine within a small margin of error. : Scenarios were built in Unity 3D to

: Distinguishes between workers, excavators, and forklifts. : Distinguishes between workers, excavators, and forklifts

: 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.

: Recognizes if a worker is facing away or kneeling, which increases risk.
