Embodiment Construction

[0021] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0022] The invention provides an underwater image processing of an underwater robot constructed by constructing a SoC system based on a Field Programmable Logic Gate Array (FPGA). The system proposed by the present invention belongs to the field of underwater image processing, and is specifically a kind of device of an underwater image real-time processing system, which realizes real-time processing and transmission of underwater images, such as figure 1 As shown, the system includes the image acquisition, image processing, image transmission and image display design modules of the underwater robot. The underwater camera is sealed with a high-permeability plexiglass cover. This invention is used on a cabled underwater robot and can be extended to other underwater products. It is mainly used for image collection, image storage and image di...

Abstract

The invention relates to an underwater image processing system of a remote operated vehicle. The underwater image processing system comprises an image acquisition module, an FPGA module and a displaymodule; the image acquisition module comprises an LED light group and a camera module; the image acquisition module and the display module are both connected with the FPGA module; and underwater images are acquired by the image acquisition module, processed by the FPGA module and displayed by the display module. According to the underwater image processing system of the remote operated vehicle, the defects that an underwater image system is long in time delay, serious in underwater image color cast, capable of generating backward flashing of the underwater images, poor in underwater image contrast, low in brightness, large is size and high in energy consumption are overcome.

Description

technical field [0001] The invention relates to the field of underwater image processing, in particular to an underwater image processing system for an underwater robot. Background technique [0002] At present, most underwater robots are underwater robots (rov) controlled by cable mode, which is to exchange data with the host computer on the mother ship through the umbilical cable, and obtain underwater image data and attitude information of the underwater robot. And the control feedback information on the shore, including obtaining the position, attitude and depth information of the underwater robot; realizing real-time interaction with the data of the host computer on the mother ship, the interaction between the man-machine screen is more vivid and specific, and is more suitable for the needs of human eyes to identify features. It helps to accurately judge the complex underwater environment and avoid the occurrence of underwater accidents of underwater robots, as well as ...
