South Korean IT and software solutions provider CyberLogitec has installed a AI-based collision prevention system at Busan New Container Terminal (BNCT), operator of Terminal 5 at Busan New Port.
The system detects workers without wearable tags and alerts straddle carrier drivers when a worker is close by in the same working lane.
CyberLogitec’s digital twin-based real-time port monitoring platform, which places people and equipment on a single coordinate system, operates AI cameras on the STS cranes to detect workers.
A vision-to-geolocation technique, developed jointly by CyberLogitec and GlobeAI, converts each detection into real-world coordinates.
These are combined with RTK positions from straddle carriers, so the distance between any worker and any machine can be calculated in real time. The system locates people without identifying them.
To avoid nuisance alarms, the system applies lane-aware logic, evaluating distance only when a carrier and a worker share the same working lane.
Alerts are tiered at 15, 10 and 5 metres and shown to drivers as directional bars on the in-cab display.
In field validation, equipment positioning was accurate to under 3 centimetres and worker localisation to under 20 centimetres.
CyberLogitec digital team leader, Dr Junhee Cho, said: “Under an STS crane, a colleague working safely in the next lane is often only a few metres away.
“If alarms sound all shift for no reason, drivers switch the system off. The measure of a safety system is not how much it catches, but whether people keep trusting it.”
