Abstract

The embodiment of the present invention discloses a method, device and system for image super-resolution reconstruction. The method includes: obtaining multiple frames of images to be processed, and selecting one frame of images from the multiple frames of images as a reference frame image; Information and equipment parameters, to obtain the image transformation parameters corresponding to the remaining frames of images; according to the image transformation parameters, taking the reference frame image as a benchmark, the remaining frames of images are calibrated to obtain the target images corresponding to the remaining frames of images; The reference frame image and the target image of each frame are reconstructed to obtain super-resolution images corresponding to multiple frames of images. Since the scheme only needs to calibrate the image according to the image transformation parameters and take the reference frame image as the reference, the calculation process is simple and the calculation amount is small, which reduces the time required for image calibration.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image super-resolution reconstruction method, device and system. Background technique [0002] Super-resolution images contain high pixel density, can provide rich detail information, and can provide accurate and detailed descriptions of objective scenes. With the continuous advancement of economy and technology, the demand for super-resolution images is very extensive, for example, it plays an important role in video security monitoring, aerial photography and other fields. However, due to the limitation of the size of the camera imaging system and sensor components, as well as the influence of factors such as the imaging environment and object movement, the acquired digital images inevitably have certain degradation or degradation, which often cannot meet the needs of reconnaissance and monitoring. It is quite difficult to obtain truly super-resolution imag...
