Abstract
The present disclosure provides a stitching quality evaluation method and system, and a redundancy reduction method and system for low-altitude UAV remote sensing images, and belongs to the technical field of image processing. The method comprises: firstly acquiring ground images using a UAV under a preset overlap degree to obtain a low-altitude UAV remote sensing image set, then stitching the low-altitude UAV remote sensing image set to obtain a stitched image, and finally performing a quality evaluation on the stitched image using an improved BRISQUE algorithm to obtain an image quality score, which is applicable to quality evaluation of visible images and multispectral images at the same time through the improved BRISQUE algorithm. In addition, the present disclosure further provides an image redundancy reduction method based on the improved BRISQUE algorithm, thereby improving the image stitching efficiency and stitching quality.
