The invention discloses a large-scale three-dimensional river scene reconstruction method based on low-detail elevation data. The method comprises the steps of obtaining river data, image data and elevation data of an area where a river is located; according to the river channel data, generating river channel semantic data capable of distinguishing river sections and confluence ports; segmenting the elevation data according to the watercourse semantic data to obtain elevation data in a watercourse coverage range, and smoothing the elevation data in the watercourse coverage range to obtain smooth elevation data; and correspondingly mapping the smooth elevation data to a river channel in the image data to obtain a smooth three-dimensional river channel scene conforming to a real river channel section. According to the method, the three-dimensional river channel scene of any area can be quickly constructed through the low-precision river channel data, the image data and the elevation data, and the method is suitable for large-scale three-dimensional river channel scene construction.
Description
technical field [0001] The invention relates to the technical field of three-dimensional river scene construction, in particular to a large-scale three-dimensional river scene reconstruction method based on low-detail elevation data. Background technique [0002] In recent years, with the continuous development of Internet of Things, big data, virtual reality, artificial intelligence and other technologies, domestic water environment intelligent visual control technology has realized the dynamic monitoring and tracking of river water environment with its advantages of digitization, intelligence and visualization. , early warning, query and visual display, etc., have achieved remarkable results in water environment management and control. However, there are still many problems in the visualization and reconstruction of 3D river scene. In the existing 3D river scene generation methods, the simulation range is mostly relatively small, and the visual presentation is still at th...
