Omnidirectional Visualizer Monitors Crowds for Disease

May-17-14 An omnidirectional thermal visualizer able to provide a 360-degree could make it easier to monitor crowded areas and identify people infected with the flu or SARS.

Thermal imaging cameras are already being used in large transportation hubs, such as airports, to detect individuals with flu-like symptoms. However, these cameras are expensive and can only monitor one lane at a time. To provide a more affordable option, a team from the Multimedia University in Malaysia used an infrared camera, customized hyperbolic hot mirror and a set of specially designed algorithms to create a system able to cover 360 degrees with a single camera. The hot mirror has been coated with infrared reflector material, which can be used to determine the body temperatures of the individuals being monitored.

Once a flu-infected person has been detected, the staff can use closed-circuit television to pinpoint the person and have security and medical personnel check them out more completely.
