Abstract

The invention provides a 6000m-level underwater micro-camera. The working depth is 6000m. According to the micro-camera, a watertight head, a rear end cover, a micro-camera cylinder and a glass observation window are pressure-resistant parts, and mutual sealing is carried out through rubber seal rings. The rear end cover and the micro-camera cylinder are made by processing high-strength light anticorrosive materials. The glass observation window is made by processing high-strength transparent glass. The integral size of the camera is small, so the camera can be arranged on a submersible conveniently. An image processing circuit board is used for carrying out postprocessing on an underwater video, and the distortion of the underwater video is reduced as much as possible. According to the micro-camera, low-voltage direct current input is employed, and the production and a technology of high-strength pressure-resistant structure materials and the high-transparency optical observation window, a highly integrated CCD imaging technology, a high-pressure sealing and anti-corrosion technology and an underwater low-illumination signal resolution technology are solved. Good video monitoring signals are provided for the submersible such as a great-depth ROV.

Description

technical field [0001] The patent of the present invention relates to a large-depth underwater micro-camera, in particular to a large-depth 6000m underwater micro-camera used on ROV and other submersibles. Background technique [0002] At present, the sea area over 4000m in the world is rich in resources and still needs to be explored. ROV and other underwater submersibles are needed for exploration. In order to obtain clear underwater images, ROV and other submersibles need to be equipped with underwater cameras for observation. [0003] At home and abroad, the existing underwater cameras have the following problems to be solved: [0004] (1) Most of the large-depth underwater cameras rely on imports, and the technology is greatly restricted. [0005] (2) The image processing technology of large-depth underwater cameras needs to be developed and researched urgently. [0006] (3) Large-depth underwater cameras have relatively strict requirements on the body’s pressure resi...
