Introduction:

Mines retain or release heat at a different rate than their surrounding. During natural
temperature variations of the environment it is possible to measure the thermal
contrast using infrared cameras.
 

Research studies:
 

• Martin Marietta Technologies Inc. has developed a short range system for the US army. The development is based on a commercial 8-12m IR sensor and uses neural networks to recognize patterns after segmentation of the image. They report 90% of target detection at the current stage of the project
