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, an underwater imaging device and an underwater imaging method. The underwater imaging device includes a casing, an object imaging device on the water surface, and a water surface ripple measurement device, and both the object imaging device on the water surface and the water surface ripple measurement device are located in the casing , the housing is provided with an optical window, the water object imaging device is used to obtain the image of the water object through the optical window, the water surface ripple measurement device is used to obtain the image of the reflection spot of the water surface corrugation corresponding to the imaging of the water object through the optical window, and the processor performs Water surface ripple reconstruction and image correction for water objects. In the present invention, the water surface object imaging device and the water surface ripple measurement device adopt a coaxial and common optical path structure, so that the water surface ripples transmitted by the imaging light of the water surface object imaging device are consistent with the water surface ripples measured by the water surface ripple measurement device, and the obtained image of the water object is reconstructed. The registration between the water surface ripples is easier, which improves the correction quality of the water object image.

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 ...
