Human being and pet detection on conveyor belts or within critical areas
The LDU – Life Detection Unit is an innovative classification system able to detect the presence of human beings (and optionally of cats and dogs) within volumes of inspection configurable during installation. A special care was devoted to the identification of babies and children. It is based on the most modern machine learning classifiers and the merging of 2D and 3D data. Part of its technology is patent pending.
The LDU was firstly designed to deal with a very specific airport safety problem: the possible passage of people on the conveyor belts carrying the hold baggage from the public to the secure area. However, due to its high modularity and scalability, it can be easily adapted for a large number of different applications of which goal is the people detection within a predetermined volume.
The system is composed by at least two analysis modules and at least one collector module. The analysis module is an embedded system performing on board all the classification tasks. The collector module is an industrial controller that collects the results of the analysis modules and provides the conveyor controller with an aggregate result. The standard kit is made up of two analysis modules and one collector module.
- The false negative classification rate is negligible.
- The false positive classification rate is extremely low not to undermine the airport regular services.
- The inspection volume as well as the system redundancy can be adapted to the customer’s needs.
- The system deals with the presence of airport operators working close to, or intruding in, the inspection volume.
- The system accuracy is not affected by temperature.
- The system identifies three states: no danger, warning and alarm in accordance with the danger score the AI classifiers associate to the analyzed scene.
The LDU system is equipped with a web interface, accessible by means of any browser or device (including tablets and smartphones). By means of this interface an operator can log in and download data, check the system operating, access the system diagnostics and modify some working settings.
The system was in field test at the Terminal 2 of the airport of Milan Malpensa for one year and has been in service since August 2018.
