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

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

Because real-world collision data is dangerous and expensive to collect, researchers used a approach: : Recognizes if a worker is facing away

The full research and technical details can be found in the article Dynamic Collision Alert System for Collaboration of Construction Equipment and Workers published in Buildings (MDPI). : By using the known size of objects

: 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.

: Distinguishes between workers, excavators, and forklifts.
