Embodiment Construction

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

[0032] The present invention is mainly based on the three-dimensional geographic information system, in order to realize the real three-dimensional simulation of the channel region, combined with real three-dimensional and virtual simulation techniques, a mixed real-view three-dimensional waterway scene configuration 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 mixed real three-dimensional channel system constructed by the present invention can more completely express the elements required by the channel management, facilitating the manager to perform...

Abstract

The invention provides a hybrid live-action three-dimensional navigation channel scene construction method. The method comprises the following steps: step 1, acquiring navigation 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 mixed live-action three-dimensional 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, and more particularly to a mixed real-view three-dimensional 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 and public gain. Improved, big data on the support capacity of channel development decision-making, accelerating science and technology empowerment, data empowerment, and promoting the depth of modern information technology water channel business. [0003] As early as 1994, the modern management program of the navigation standards was proposed, using technologies such as computer, communication and positioning, etc., using techno...
