Description

technical field [0001] The invention relates to the technical field of optical super-resolution, in particular to an image stabilization, non-uniformity correction and super-resolution system based on a micro-scanning platform. Background technique [0002] At present, there are many non-uniform correction methods for infrared focal plane detectors, including calibration-based correction algorithms based on reference sources and adaptive correction algorithms based on scenes. The former algorithm is relatively simple and easy to implement in hardware, but the calibration process needs to block the detector with a black body and temporarily stop normal work. This method cannot achieve real-time correction. However, the current traditional scene-based adaptive correction uses the calculation of multiple frames of images to obtain non-uniform correction parameters. The complexity of the algorithm is relatively high, and it is often easily restricted by hardware and systems, and...
