Cheap cameras developed to minimise crowd Injuries

by FFE EU News Staff

 

Take a cheap infrared camera and a monochrome camera, combine the two and set it up with a computer that can detect temperature and light differences. The result is a mega-machine that can measure crowd densities and provide alerts when crowds have reached dangerous levels.

 

The smart system has been developed by Dr Amin Al-Habaibeh and his team of researchers at the Nottingham Trent University School of Architecture, Design and the Built Environment. With the camera system, the density of crowds at a given area can be measured in real-time. The system is also able to provide crowd estimates with the least margin of error.

 

Dr Amin Al-Habaibeh said ‘Large scale public events still present huge safety risks and there are several recent examples of incidents which have resulted in loss of life.

‘It’s important that technology helps minimise those risks and, where possible, helps prevent any instances such as crushing. The project has many potential applications around the world including sport events and city festivals.’

 

The monochrome camera can detect individuals in a crowd through outlines. The infrared camera meanwhile monitors each person by sensing the heat that they release from their bodies. A density of five people per square metre is considered potentially unsafe. The camera can also do this at night.

 

Post-grad researcher Saied Yaseen said that the system ‘will give security staff the knowledge of whether or not people’s safety is at risk, even when this is impossible tell with the naked eye.’
