Problems solved by technology
[0003] At present, in related technologies, there are many ways to render high-precision maps. For example, open source graphics library (OpenGraphics Library, OpenGL) is used to render wide roads. One problem is the lack of rendering integrity or repeated rendering, especially for roads located at turning positions

The invention relates to a map road rendering method and device, equipment and a storage medium. The method comprises the following steps: acquiring lane data, selecting a plurality of road center line coordinate points as construction coordinate points in a road center line coordinate point sequence at intervals, and obtaining a connection coordinate point according to two adjacent construction coordinate points and a slope between the two construction coordinate points; then constructing rendering graphs around the construction coordinate points and the corresponding connection coordinate points, rendering each rendering graph to obtain a road rendering surface, and finally drawing lane lines on the road rendering surface by using the lane data to obtain a rendered road surface. As the rendered graphs constructed each time share one group of coordinate points, the constructed rendered graphs can completely and continuously cover the whole road, the situation that part of road surfaces are not rendered is greatly avoided; meanwhile, the problem that two adjacent rendered graphs are not overlapped due to the fact that one group of coordinate points are shared is solved, and the road surface rendering efficiency is improved, that is, the condition that part of roads are rendered repeatedly is avoided.
Description
technical field [0001] The present application relates to the technical field of automatic driving, in particular to a map road rendering method, device, device and storage medium. Background technique [0002] The field of automatic driving needs to use high-precision maps as the basis of automatic navigation. In order to make high-precision maps display more detailed elements and beautify high-precision maps, high-precision maps will be rendered. [0003] At present, in related technologies, there are many ways to render high-definition maps. For example, open source graphics library (OpenGraphics Library, OpenGL) is used to render wide roads, but most of the related high-precision map rendering technologies will encounter One of the difficulties is the lack of rendering integrity or repeated rendering, especially for roads located at turning positions. Insufficient rendering integrity means that part of the road at the turning position is not rendered, and repeated rende...
