Multi-source data fusion and integration display system and method for underwater slope reconnaissance

Abstract

The invention provides a multi-source data fusion and integration display system and method for underwater slope reconnaissance. The system comprises a data collection and transmission module, a dataextraction module, a data management module, a data analysis and processing module, an underwater slope geographic information module, an underwater slope substrate classification display module and an underwater slope geological information module, wherein regional stratigraphic information and the internal defects of a building are disclosed according to interpreted and analyzed data. A data warehouse system is established to carry out uniform management on multi-beam sounding data, side scanning sonar data and seismic data. Multi-source data fusion and integration display is realized, system architecture is uniform, performance is stable and reliable, distributed systems can realize seamless integration, and interoperability is high.

Description

Technical field [0001] The present invention relates to the technical field of data processing, in particular, to a system and method for fusion and integrated display of multi-source data of underwater slope survey. Background technique [0002] As the "pioneer" of maritime activities, marine surveying and mapping has encountered unprecedented opportunities and challenges in terms of technology and equipment. The construction of "digital ocean" and "transparent ocean" contributes to the development of deep sea resources, marine ecological environment monitoring, marine fishery production, and marine The smooth development of project construction and other activities has important guarantee significance. [0003] At present, driven by computer information technology, a number of full-coverage, high-efficiency and high-precision equipment such as airborne laser sounding, multi-beam sounding, side scan sonar system, and three-dimensional image sonar system are popularized in the fiel...

AI Technical Summary

Problems solved by technology

However, these acoustic equipment are mainly operated by ships, and the acoustic energy is attenuated and interfered greatly in the process of water body propagation, which cannot meet the accuracy requirements of comprehensive data survey of underwater slope topography, stratum lithology, and geological structure.

Although the error can be reduced by using the deep tow method or direct detection by ROV, the survey data sources of each acoustic equipment are heterogeneous, interoperability is difficult, and the efficiency of data acquisition by users is low, which seriously affects the research and application of marine science.
