Problems solved by technology

These methods are too complicated and do not address the reality that current road designers generally use 2D road design software for road design, and the modeling cycle is long, which cannot satisfy road designers to quickly view the 3D renderings of the design results

Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] A method for rapid modeling of three-dimensional roads based on vertical and horizontal design, characterized in that the modeling method includes:

[0018] a. One-to-one correspondence between the two-dimensional road design data and the three-dimensional modeling layer, that is, associating the road centerline, lane line and other marking lines with the modeling layer;

[0019] b. Save the road profile, cross-section and slope information into the 3D road modeling element set, where the road profile information includes the chainage, elevation and radius, and the road cross-section...

Abstract

The invention relates to a plane-vertical-horizontal design-based rapid three-dimensional road modeling method with the advantages of rapidly carrying out road modeling, being convenient to operate and greatly shortening the modeling period, and belongs to the technical field of road modeling. The modeling method comprises the following steps of: enabling two-dimensional road design data to be in one-to-one correspondence with three-dimensional modeling map layers; storing vertical section, horizontal section and slope information of a road into a three-dimensional road modeling element set; detecting errors such as breakpoints, overlap and the like of the two-dimensional road design data; cutting the two-dimensional road design data into three-dimensional modeling data; generating a pavement, a slope and other road elements; carrying out rendering; automatically generating streetlamps, signal lamps, trash cans and other road ancillary facilities according to point coordinates and facility types of the road ancillary facilities in the modeling data, and finally displaying a three-dimensional model from various visual angles in a grid or entity manner. The method provided by the invention is widely used for three-dimensional road modeling.

Description

technical field [0001] The invention relates to a fast three-dimensional road modeling method based on horizontal, vertical and horizontal design, and belongs to the technical field of road modeling. Background technique [0002] The traditional 3D road modeling methods are mainly based on professional 3D modeling software such as 3D Max, solidworks, UG, etc., or directly design and model with 3D road design software. These methods are too complicated and do not address the reality that current road designers generally use 2D road design software for road design, and the modeling cycle is long, which cannot satisfy road designers to quickly view the 3D renderings of the design results. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides a rapid three-dimensional road modeling method based on horizontal, vertical and horizontal design, which can quickly carry out road modeling, is convenient t...
