Underwater polarized light imaging method and imaging system

Abstract

The invention discloses an underwater polarized light imaging method and system, and the method comprises the steps: enabling a light source to emit visible light, and enabling the visible light to irradiate an underwater target object after penetrating through a polarizer; filtering underwater interference light information by using an analyzer located at the receiving device; acquiring information of a target object by a receiving device; and performing image restoration on the acquired information through a compressed sensing restoration algorithm to obtain an image of the target object. In this way, the compressed sensing technology and the underwater polarized light imaging technology are combined, interference light information can be effectively filtered out through the filtering mode that the polarizer and the analyzer are combined, meanwhile, the compressed sensing recovery precision is improved, more effective information of a target object is obtained, and therefore in the underwater environment, the efficiency and quality of target image reconstruction are improved, and the competitiveness of the data center is improved.

Description

Technical field [0001] Technical Field The present invention relates to optical imaging, and more particularly to an underwater polarized imaging method and an imaging system. Background technique [0002] With the development of modern optical technology, underwater optical detection applications more widely. Underwater imaging apparatus having a simple optical imaging, can provide a wealth of information and so on. However, light transmission in water, there are a variety of interference, a great impact on these interference can underwater imaging quality and efficiency. Underwater scene, the scattered light of the main factors affecting the image quality, and water molecules in water suspended particles scattering light waves generated, wherein the portion of the scattered light will propagate in the direction of the probe, after the formation of scattered light. After the scattered light is superimposed on the target information, the contrast of the images acquired probe is l...

But there are a lot of suspended particles in the water, the light received by the receiver, in addition to the useful information light reflected by the target object, also has a large amount of backscattered light caused by suspended particles, and these backscattered light is interference light, which will Reduce the final imaging quality, specifically manifested as blurred, blurred outlines of the image presented, and poor contrast
