Abstract

The invention discloses a navigation road surface generation method and system, and the method comprises the steps: generating a first straight line in a navigation path; obtaining a direction vector of the first straight line; obtaining a normal vector of the first straight line according to the direction vector; respectively extending two points at two sides of each of two end points of the first straight line according to the normal vector, wherein the two points extended at two sides of each of two end points are located in the normal vector direction of the first straight line; taking the extended points of the two end points, and generating a plurality of triangles; generating a navigation road surface of the first straight line, and carrying out the rendering of the navigation road surface. According to the scheme of the invention, two points are extended at the two sides of each of two end points of the first straight line, and the existing points are taken as the reference to generate the plurality of triangles, and the navigation road surface is formed, so as to facilitate the rendering. The method is simple and precise, is uniform in road surface, and is high in efficiency.

Description

technical field [0001] The invention relates to the field of control, in particular to a method and system for generating a navigation road surface. Background technique [0002] During the navigation process, a road surface can be generated for a given route and displayed to the user in the form of a road surface, thereby highlighting the navigation route. [0003] However, at present, for the road surface generated by a given route, the algorithm for generating the road surface is complicated, and the width of the road surface is uneven and the data is not accurate due to algorithm problems. Contents of the invention [0004] In view of this, the present invention provides a method and system for generating a navigation road surface to solve the problems in the prior art that the algorithm for generating a given off-road surface is complex, and the road surface is uneven and the data is inaccurate due to algorithm problems. The specific solution is as follows : [0005...
