Abstract

The invention discloses an underwater image splicing method and device, and belongs to the technical field of image processing. The method comprises the following steps: acquiring at least two underwater images to be spliced; sequentially performing red channel attenuation compensation processing and white balance processing on each underwater image to obtain a preprocessed underwater image corresponding to each underwater image; performing image enhancement processing on each preprocessed underwater image based on the multilayer image pyramid to obtain an enhanced underwater image corresponding to each preprocessed underwater image; performing image registration processing on the at least two enhanced underwater images based on grid optimization to obtain registered underwater images; performing image fusion processing on the registered underwater images based on a Laplace pyramid multi-scale image fusion algorithm to obtain a fused underwater image; and determining that the fused underwater image is a spliced underwater image, and outputting the spliced underwater image. The invention realizes underwater image splicing method.

Description

technical field [0001] This application belongs to the technical field of image processing, and specifically relates to an underwater image stitching method and device. Background technique [0002] Underwater images, also known as underwater optical images, refer to images below the water surface captured by underwater imaging equipment such as unmanned submersibles or underwater vehicles. It is different from traditional underwater images. Due to the serious attenuation, scattering and absorption of light in water, underwater images often have quality problems such as color distortion, blurred details, low contrast and clarity, and limited field of view. question. Therefore, there is an urgent need for an underwater image stitching method for improving the above problems. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a method and device for underwater image stitching, which can solve the quality problems of c...
