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.
