Problems solved by technology

The more intense the ripple, the more serious the distortion and distortion of the image, especially when underwater imaging of water surface objects is applied to the ocean. In the case of strong waves on the sea surface, the image is completely distorted and the target cannot be identified.

Abstract

The invention provides an underwater imaging system, underwater imaging equipment and an underwater imaging method. The underwater imaging equipment comprises a shell, an overwater object imaging device and a water surface ripple measurement device. The overwater object imaging device and the water surface ripple measurement device are located in the shell. An optical window is set on the shell. The overwater object imaging device is used for obtaining an overwater object image through utilization of the optical window. The water surface ripple measurement device is used for obtaining images of a reflected facula of a water surface ripple corresponding to the overwater object image, through utilization of the optical window. A processor carries out water surface ripple reconstruction and calibrates the overwater object image. According to the system, the equipment and the method, the overwater object imaging device and the water surface ripple measurement device employ a coaxial commonlight path structure, the water surface ripple transmitted by imaging light of the overwater object imaging device is consistent with that measured by the water surface ripple measurement device, andregistration between the obtained overwater object image and a reconstructed water surface ripple is relatively easy, and calibration quality of the overwater object image is improved.

Description

technical field [0001] The invention relates to the technical field of underwater imaging, in particular to an underwater imaging system, an underwater imaging device and an underwater imaging method. Background technique [0002] Imaging objects above water from underwater is an interesting problem. Underwater imaging of water surface objects has applications in many fields, but there are also many problems, such as absorption and attenuation, scattering, and refraction of light by water bodies. Among them, the problem of refraction of light by water body refers to the refraction of imaging light at the air-water interface, and the refraction angle is related to the corrugated shape of the water surface. Because the actual water surface is corrugated and fluctuates randomly, different imaging rays are incident on the surface at different refraction angles. In optical systems, images are distorted and distorted. The more severe the ripples, the more serious the distortion ...
