Abstract
Today’s thermal imagers have a very limited spatial resolution. This article analyses the deficiencies and proposes to use a system called SuperResolution to enhance the spatial resolution. SuperResolution combines de-convolution with super-sampling and therefor addresses the two main limitations of IR-cameras. SuperResolution works by capturing multiple images of a hand-held camera quickly, and then computing a high resolution image from them. Finally, the SuperResolution approach is analyzed in detail, to verify the effective resolution enhancement and to ensure that temperature values derived from the final images are correct.
