Embodiment Construction

[0031] In order to make the technical problems, technical solutions and advantages to solve the present invention more clearly, and will be described in detail below with reference to the accompanying drawings and specific examples.

[0032] The present invention mainly based on the three-dimensional geographic information system, in order to realize the real three-dimensional simulation of the channel area, combined with digital twin technologies, proposed a real three-dimensional digital twin channel scenario construction method. The method fully considers the various elements of the three-dimensional scenes of the channel area and dynamically manifests the key information required by ships, water flow, and meteorological channel management. The real-three three-dimensional digital twin channel system constructed by the present invention can more completely express the elements required by the channel management, facilitating the manager to perceive the scene of any location of ...

Abstract

The invention provides a live-action three-dimensional digital twin channel scene construction method. The method comprises the following steps: step 1, obtaining channel area land elevation data in a grid form; step 2, obtaining channel underwater water depth data in a grid form; step 3, constructing an overwater and underwater integrated terrain model according to the grid-form channel area land elevation data and the channel underwater depth data obtained in the step 1; step 4, acquiring a land utilization type and performing terrain mapping; step 5, constructing a water surface effect of the water body; step 6, constructing a land three-dimensional landscape model; step 7, simulating the ship running on the water surface; and step 8, simulating the environmental meteorological information. According to the method provided by the invention, a three-dimensional digital channel management platform in a desktop end form or a webpage form can be constructed on computing equipment such as a personal computer, a smart phone and the like.

Description

Technical field [0001] The present invention belongs to the field of three-dimensional geographic information system, in particular to a real three-dimensional digital twin waterway scene configuration method. Background technique [0002] According to the "Digital Transportation Development Plan for Digital Transportation Development", digital management of the channel network can make the channel network to run cross-business, cross-regional, cross-time synergistic management capability, and the quality of channel information services, convenient levels and public gains. Improve, big data on the support capacity of channel development decisions is significantly enhanced, accelerate scientific and technological empowerment, data empowerment, and promote the depth integration of modern information technology waterway services. [0003] As early as 1994, a modern management program for navigational information was proposed, using technologies such as computer, communication and po...
