HIGH ACCURACY INFRARED MEASUREMENTS

摘要

Imaging systems and methods are provided, which use visual range and infrared thermal camera(s), set at fixed spatial relations and focused at an intersection of their optical axes, to focus the infrared camera(s). The cameras are moved together, and the object is positioned at the focus of all cameras upon identifying an overlapping of the visual range images. An image processor fuses images and derives infrared measurements of different regions in object. Prior knowledge concerning the temperature distribution in different regions of the object is utilized to enhance infrared measurement accuracy.
