Rotating wheel type underwater polarization camera

Abstract

The invention discloses a rotating wheel type underwater polarization camera which comprises a sealed cabin, and an illumination module, an imaging unit, a polarization module, a control unit and a power supply module which are mounted in the sealed cabin through an internal bracket, The illumination module, the imaging unit and the polarization module are all connected with the control unit; thepower supply module provides working voltage for the whole rotating wheel type underwater polarization camera; Wherein the illumination module is used for illuminating a target object, and the polarization module is used for carrying out polarization processing on incident light, so that the polarization directions of the light irradiated to the imaging unit are consistent; And the imaging unit performs polarized light imaging on the target object. The device is reasonable in structure and simple to operate, and can quickly shoot the polarization image of the underwater object.

Description

technical field [0001] The invention relates to an underwater polarization information measuring device, in particular to a rotary wheel type underwater polarization camera. Background technique [0002] Polarization information is an important information contained in light. The polarization information will change after light is reflected by different objects. Therefore, by taking polarization photos of objects, we can effectively understand the surface reflection and scattering information of objects, and improve imaging detection capabilities. [0003] With the continuous deepening of human research on the ocean, people also have higher requirements for underwater imaging. However, due to the large scattering of light by various fine particles floating in the water body, and the absorption of light by the water body, the light energy Rapid attenuation in water makes underwater imaging appear blurred and has low contrast. If the underwater imaging system is equipped with...

Problems solved by technology

[0003] With the continuous deepening of human research on the ocean, people also have higher requirements for underwater imaging. However, due to the large scattering of light by various fine particles floating in the water body, and the absorption of light by the water body, the light energy Attenuates rapidly in water, causing blurred underwater imaging and low contrast

If the underwater imaging system is equipped with an underwater light source, the backscattering of the water body will greatly intensify the fogging phenomenon, which makes it impossible for people to obtain clear underwater images
