Underwater high-definition photographic system for deep sea

Abstract

The embodiment of the invention discloses an underwater high-definition photographic system for a deep sea. The underwater high-definition photographic system comprises pressure-resistant glass, a 16-mm fixed camera lens, an image collecting module, an image processing module, a power source management module and an interface, wherein the thickness of the pressure-resistant glass is 15 mm-20 mm, the fixed camera lens is arranged at the rear end of the pressure-resistant glass, the image collecting module is arranged at the rear end of the lens, the image processing module is arranged at the rear end of the image collecting module, the power source management module is arranged at the rear end of the image processing module, and the interface is formed in the rear end of the power source management module. The pressure-resistant glass, the lens, the image collecting module, the image processing module, the power source management module and the interface are packaged through a frame which is wholly sealed and resistant to pressure. Images are collected through a low-pressure-difference serial port of the MIPI interface and a backside-illuminated CMOS sensor, image quality can be better under the condition of insufficient light in the deep sea, and a towed body working in the deep sea can be higher in image collecting speed and anti-interference capacity when shaken violently in ocean currents.

Description

Technical field [0001] The invention belongs to the field of digital image technology, and particularly relates to a high-definition camera system under deep sea water. Background technique [0002] The deep-sea camera is a camera used to take pictures of geology, biology and sea current dynamics on the seabed and in the water. It is very useful in resource exploration such as polymetallic nodules, manganese crusts and massive sulfides. At present, underwater cameras in deep seas are generally less than 10 million pixels, using CCD image sensors and DSP processing. The CCD image sensor needs to provide a lot of voltage, the whole circuit is complicated, the power consumption is large, and the image collection speed is slow. At the same time, the CCD sensor performs poorly in low light. [0003] Nowadays, with the rapid development and popularization of CMOS technology and the continuous maturity of CMOS circuit denoising technology, more and more high-density and high-quality CMO...

Problems solved by technology

For the DVP parallel port used in traditional underwater cameras, clock synchronization signals such as PCLK, VSYNC, and HSYNC are required to cooperate with data transmission. There are many signal lines, large interference, weak anti-interference ability, limited signal integ
