Abstract

The embodiment of the invention discloses a true three-dimensional road intelligent design method and a true three-dimensional road intelligent design system. The method comprises the following steps of: performing road route selection and horizontal, longitudinal and transverse parameter design of the road in a high-precision three-dimensional terrain scene; adjusting the horizontal, longitudinal and transverse design parameters in the three-dimensional terrain scene; calculating a spatial position relationship between a road model and the three-dimensional terrain scene according to the design parameters, and generating a real three-dimensional road model, wherein the real three-dimensional road model comprises three-dimensional coordinate information which describes the road surface, and road surface texture information; and modifying the terrain of a region where the road is positioned according to the spatial position relationship between the real three-dimensional road model and the three-dimensional terrain scene, and establishing a road model which is seamlessly jointed with real earth surface. By performing road route selection in the high-precision three-dimensional terrain scene and designing and adjusting the horizontal, longitudinal and transverse parameters, the method and the system realize three-dimensional terrain scene-based road design and visualization.

Description

technical field [0001] The invention relates to the technical fields of road design and virtual reality, in particular to a method and system for road intelligent design based on true three-dimensional roads. Background technique [0002] With the rapid development of transportation infrastructure construction, more and more roads of various grades need to be built. The road design is different from other civil engineering designs, and has its own characteristics, which are mainly manifested in the following two aspects: first, the road is a strip-shaped object, which will be affected by factors such as terrain, landform, and environment along the line; 2. Road design is based on the topographic map obtained in the previous survey for line selection or on-site alignment, so the preliminary work will cost a lot of manpower and material resources; the traditional road design is to first manually interpret the data on the topographic map, and then carry out the preliminary rout...
