High-precision underwater imaging method and device

Abstract

The invention discloses a high-precision underwater imaging method and device, and the method comprises the steps: constructing a scene radiation sub-network, inputting a collected underwater distorted image, and outputting a scene radiation pattern; estimating a transmissivity graph and a background light graph from the underwater distorted image, and synthesizing the scene radiation graph, the transmissivity graph and the background light graph into a simulated underwater distorted image according to an underwater imaging formula; constructing a prior discrimination sub-network based on the underwater distorted image, inputting a scene radiation pattern, and outputting the underwater image degradation degree; and optimizing scene radiation sub-network parameters based on the underwater image degradation degree so as to output an optimized high-precision scene radiation pattern. According to the method, the problem that the underwater image has no true value when the underwater imaging problem is solved by using deep learning is solved, the dependence on a true value image is avoided, and a clear, high-contrast and color-corrected underwater image is recovered by using an underwater distorted image in combination with an underwater imaging model.

Description

technical field [0001] The invention relates to technical fields such as underwater imaging, and in particular to a high-precision underwater imaging method and device. Background technique [0002] In recent years, marine environment detection, especially underwater detection technology has attracted more and more attention. The urgent need for underwater resource development puts forward a requirement for high-quality underwater imaging technology. Underwater imaging technology is mainly restricted by two factors: one is the absorption by the water body and particles in the water, and the other is the scattering by the water body and particles in the water, resulting in color shift, low contrast, and blurred images in underwater images. Therefore, restoration The normal color of underwater scenes, the improvement of contrast, and the enhancement of details have become the focus of many scholars' research. [0003] The traditional underwater imaging method is divided into...

Problems solved by technology

However, due to the particularity of the underwater environment, there are very few real underwater scene data sets, and it is difficult to learn prior information from underwater images with a small number of data sets.
