3D Seabed Terrain Modeling Service with GPU Acceleration High-precision Restoration and Land-sea Integration for Marine Simulation

Based on the self-developed National Marine Digital Simulation Platform, Qingdao Jumeirah industry company specializes in 3D seabed terrain modeling and marine environment simulation. Breaking through the technical barriers of foreign mainstream software, the company has realized full-process domestic, high-precision and high-efficiency seabed terrain modeling solutions. The technology is widely applicable to marine scientific research, maritime engineering, underwater combat simulation, smart ocean construction and other professional scenarios.

The entire modeling system is independently built on a C++ underlying framework, serving as a fully domestic alternative to MATLAB and other imported industrial simulation software. It supports seamless calling, compilation and operation of M-files, fully compatible with mainstream scripting formats used in traditional marine modeling industries, without restructuring existing engineering data. The fully self-controllable system eliminates copyright and technical restriction risks, making it highly suitable for confidential important projects and key marine engineering applications.

Equipped with CUDA and TTP multi-core parallel computing technology, the platform optimizes core algorithms for large-scale matrix operation and massive seabed point cloud data processing. Compared with traditional modeling methods, it rapidly completes the calculation, fitting and reconstruction of large-area, high-density seabed terrain data. It effectively solves common difficult points of conventional software such as lagging operation, slow computation and unbalanced precision, enabling fast generation and iterative update of high-quality seabed terrain models.

Integrating multi-source marine survey data including seabed point clouds and terrain elevation data, the system accurately reproduces complex micro-landforms such as seabed reefs, gullies, slopes and undulating seabed surfaces. Breaking the limitations of traditional 2D planar modeling, it supports 3D static terrain modeling + 4D time-varying dynamic simulation. It can dynamically simulate the impacts of tides, ocean currents and water depth changes, ensuring that the simulated terrain is highly consistent with real marine environments.

Built on a 3D digital earth framework, the platform realizes integrated land and marine terrain modeling, as well as seamless linkage between 2D GIS data and 3D scene rendering. Adopting advanced computer graphics technology, it rapidly extracts terrain feature data and renders high-definition 3D seabed scenes in real time. It intuitively displays terrain profiles, landform structures, water depth parameters, sound field distribution and other core data, delivering realistic, three-dimensional and intuitive visualization effects.

The system embeds independently developed function libraries and toolkits for marine dynamics, underwater acoustics and terrain correction, as well as dedicated NetCDF marine data processing modules. It supports full-process operations including seabed modeling, data calibration, environmental assimilation and simulation forecasting without complex programming. It greatly lowers technical thresholds and meets the diverse needs of university scientific research, industrial engineering and important simulation applications.

The modeling results can be seamlessly applied to underwater sound field simulation, marine environment forecasting, maritime engineering planning, seabed resource exploration, underwater combat scenario deduction and important equipment simulation testing. The system supports massive terrain data storage, management and intelligent analysis, and can be well connected with various marine simulation systems and GIS platforms, covering both civilian smart ocean construction and important marine simulation training scenarios.
