This invention relates to a method and system for super-resolution reconstruction of infrared images based on a micro-scanning device, belonging to the field of infrared image processing technology. The method includes: controlling a micro-scanning device to acquire multiple frames of low-resolution infrared images with sub-pixel displacement; constructing a high-resolution grid, projecting pixel values ​​onto the high-resolution grid through sub-pixel fusion, and accumulating weights to generate a reconstructed image and a weight matrix; generating a confidence map based on the weight matrix, calculating an adaptive sharpening coefficient based on the confidence map, and injecting high-frequency details into the reconstructed image to obtain a 2x super-resolution reconstructed image. Further, a dual-cascade fusion architecture is adopted, transforming the original multi-frame images into four sets of images, each reconstructed at 2x, and then performing a secondary fusion on the resulting intermediate images to achieve 4x super-resolution reconstruction. This invention can effectively suppress artifacts in non-ideal sampling areas, overcome the magnification limitations of fixed-magnification devices, and is independent of training data, exhibiting strong generalization ability.

This technical solution belongs to the field of nail clipper technology, specifically relating to a nail clipper with a magnifying function. It includes a nail clipper body with a trimming area for trimming nails; and a magnifying device installed at the front end of the nail clipper body to magnify the trimming area. The magnifying device includes: a mounting bracket installed at the front end of the nail clipper body, with a locking groove on one side; and a magnifying glass with a locking part on one side that engages with the locking groove, with the other side of the magnifying glass extending out of the mounting bracket. The magnifying glass is mounted by engaging the locking part with the locking groove on the mounting bracket, while the other side of the magnifying glass remains exposed, preventing the mounting bracket from obstructing the edge of the view. This provides a wide field of view, allowing the user to easily observe the hand placed within the trimming area of ​​the nail clipper body, ensuring safe use.
