Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to an intelligent detection method and system for underwater engineering structures based on digital twins. Background technique [0002] The statements in this section merely mention background related to the present invention and do not necessarily constitute prior art. [0003] Underwater engineering structures are widely used in inland rivers and marine waters. Due to the complex working environment, the increasingly large and complex underwater engineering structures not only have high construction costs, but also are difficult to monitor and maintain. Therefore, it is particularly important to accurately detect and evaluate their performance. Through the health detection and damage diagnosis of the structure, it is possible to give an early warning of its possible damage, so that maintenance and reinforcement can be carried out in advance, so as to avoid possible...
