Problems solved by technology

The manual modeling method can make the model very delicate and real, but its biggest disadvantage is that the manual modeling workload is heavy and the efficiency is extremely low, which seriously affects the application of 3D road models in various fields
At the same time, the storage of the model requires a large capacity space, which greatly limits the development of 3D maps.

Abstract

The invention discloses a three-dimensional (3D) road modeling method. The method comprises the following steps of: A) acquiring two-dimensional road coordinate data; B) acquiring road edge characteristic points corresponding to the two-dimensional road coordinate data according to the width of the road and the two-dimensional road coordinate data; C) determining a road surface area of the three-dimensional road according to the road edge characteristic points; and D) meshing the road surface area to obtain a three-dimensional road model. By the method, a 3D virtual road model with high simulation degree can be dynamically generated in real time according to two-dimensional map road data, so that the 3D road modeling is greatly accelerated. Thus, the method greatly improves the workability of the map road and the working efficiency of the 3D road modeling.

Description

technical field [0001] The invention relates to the field of three-dimensional navigation and modeling, in particular to a method and device for modeling three-dimensional roads. Background technique [0002] In many application fields, the traditional two-dimensional map uses the combination of points and lines to describe the objective world. Although this method can quickly and timely provide the basic needs of users, it reflects a flat information. The traditional two-dimensional Maps have become less and less able to meet the needs, replaced by 3D maps that can produce a sense of immersion. With the upgrading of electronic product hardware, the ground Figure three Dimensionalization has become possible. The 3D map can not only provide all the information required by the two-dimensional map, but more importantly, it can reflect a three-dimensional world, and can provide users with richer and more intuitive visual effects, making people feel immersive. [0003] 3D maps...
