Multispectral Augmented Reality Deepwater Maintenance Visualization Expert System

Abstract

The present invention proposes a multi-spectral enhanced reality deep-water maintenance visualization expert system, including: a multi-spectral machine vision underwater imaging subsystem collects environmental signals around reservoir dams under complex deep-water conditions, and generates real-time underwater image data of deep-water dams ; The 3D scene augmented reality subsystem constructs 3D scene images from the underwater image data of deep-water dams, and generates 3D augmented reality fusion images; the video expert command subsystem and the multi-spectral machine vision underwater imaging subsystem and 3D scene augmented reality subsystem System connection, used for remote control and management of multi-spectral machine vision underwater imaging subsystem, and real-time calculation and judgment of disease types of deep-water dams based on underwater image data, environmental data and 3D augmented reality fusion images of deep-water dams, and release early warning information , to generate command decisions for maintenance work. The invention can solve various problems such as complex lighting conditions, light scattering and refraction by suspended particles in the water body, and real-time command limitation in deep-water dam maintenance.

Description

technical field [0001] The invention relates to the technical field of water conservancy facility dam safety monitoring, in particular to a multi-spectral augmented reality deep-water maintenance visualization expert system. Background technique [0002] In the maintenance of deep-water dams, due to complex lighting conditions, light scattering and refraction by suspended particles in the water body, blurred image capture, limited display of scene information in deep water, types and sizes of dangerous situations, etc., it causes various problems such as difficult judgment and real-time command restrictions. [0003] The existing deep-water dam maintenance adopts the following two forms: [0004] (1) Underwater maintenance by divers [0005] This method has the following problems: the depth of the dive is limited; it is dangerous for divers to go into the water for inspection; the visibility of the water body in the reservoir is low, and the human eye cannot see clearly; it...

AI Technical Summary

Problems solved by technology

[0005] This method has the following problems: the depth of diving is limited; it is dangerous for divers to go into the water for inspection; the visibility of the water body in the reservoir is low, and the human eye cannot see clearly; it is difficult for divers to carry out repair work underwater;

[0007] This method has the following problems: the submersible has a limited viewing angle, and it is difficult to control the rotation and displacement; ordinary optical imaging is difficult to adapt to the complex water quality environment; it is difficult for shore experts to fully understand the underwater real scene

[0008] To sum up, how to quickly and effectively carry out deep water real-time online exploration to find hidden dangers such as deformation, cracks, seepage, etc., reduce the defects of repeatability and poor guidance of maintenance work, and carry out timely and effective reinforcement treatment of dam projects has always been a key issue of water conservancy.
