LDU™ is an innovative embedded detection system able to identify the presence of human beings (and optionally of other categories of interest) within volumes of inspection configurable during installation. A special care was devoted to spot babies and children. It is based on cutting-edge AI technology coupled with 3D computer vision.

An innovative AI-based detection system
Safety, first
LDU™ was designed to deal with a very specific airport safety problem: the possible dangerous unnoticed or unauthorized passage of people on the conveyor belts carrying the hold baggage from the public to the secure area. The system is able to handle the presence of airport operators working close to, or intruding in, the inspection volume and is optimized to be installed on take-away conveyors, check-in desks and baggage carousels. However, thanks to its high modularity and scalability, it can also be effectively used in different applications and contexts.
The system’s brain
The LDU™ brain is the analysis module, an embedded system that performs all the computational tasks onboard. More modules can be used together to obtain a wider analysis area or to achieve a greater redundancy. The analysis results are communicated to an external device by means of either a TCP/IP open string-based protocol or digital IOs. An operator can log into every module through a web interface, accessible by any browser or device.



LDU™ is covered by the Italian patents No. 102017000064268, 102017000064301 and by the following patent pending applications No. EP3635614, US 2020/0097758.
System features

Performances are extremely high in terms of both precision and recall, so that the system is very effective without undermining the airport regular services.

The presence of airport operators working close to, or intruding in, the inspection volume is correctly handled.

A special care was devoted to spot babies and children.

The system is able to assess the current actual danger identifying three different conditions: no danger, warning and alarm.

A web interface, accessible by means of any browser or device (including tablets and smartphones), allows an operator to perform all the configuration and inspection tasks.

Accuracy is not affected by temperature or sunlight.

The inspection volume as well as the system redundancy can be adapted to the specific application needs.

The analysis results are communicated through TCP/IP or digital IOs.

LDU™ can be supervised by a SCADA system.

The system was validated during a one year field test and is currently in operation.
