Thermography Based Crowd Temperature Monitoring

A crowd temperature monitoring system has been developed using expertise in infrared imaging for missile applications. DRDO lab in collaboration with industry partner has innovated and developed algorithms for thermography in outdoor conditions. Advanced face detection techniques have been used over thermal images. The system consists of a thermal camera and a desktop/laptop computer. Artificial Neural Network, trained with a very large in-house thermal database, allows face recognition directly on the running video from the IR thermal camera. A large number of people can be thermally profiled outdoors without disturbing their movements. Persons showing more than pre-set thermal threshold can be earmarked, recorded and real time inputs can be given to authorities.
