Super-resolution techniques were applied to infrared thermographic temperature measurement for the improvement of spatial resolution of the infrared image with limited number of imaging pixels. In the proposed super-resolution technique, a high resolution image was produced from plural low resolution images with sub-pixel displacements. The super-resolution scheme was developed based on the displacement analyses in the sub-pixel level for low resolution images based on the image correlation and subsequent interpolative reassignment of the pixel values from low resolution images to the high resolution image. The practicability of the developed super-resolution infrared themiography was experimentally demonstrated.
