Embodiment Construction

[0026] A method for generating a high-precision map path, comprising the following methods:

[0027] S1. Obtain the start point and end point according to the user's needs;

[0028] S2. Use signal points available in the area between the starting point and the end point as passing points, iterate and aggregate each passing point, and generate an aggregation list;

[0029] S3. Combining the aggregation list, draw the passing points to form a new path map.

[0030] Further, in the step S2, the obtainable signal points include vehicle positioning points, pedestrian mobile device positioning points, and UAV mapping points.

[0031] Further, in the step S2, the obtainable signal points are obtained through satellites, mobile devices, and auxiliary devices; the mobile devices include mobile phones, tablets, and notebooks; the auxiliary devices include drones and surveying vehicles.

[0032] Further, in the step S3, the new road map is drawn by using the points as moving line point...

Abstract

The invention belongs to the technical field of electronic maps, and particularly relates to a high-precision map path generation method. The method comprises the following steps: S1, acquiring a starting point and an ending point according to user requirements; S2, taking signal points which can be obtained in the area between the starting point and the ending point as passing points, and performing iteration and aggregation on each passing point to generate an aggregation list; and S3, in combination with the aggregation list, drawing passing points to form a new path diagram. According to the invention, the relation among the real-time positioning point, the position and a moving line object is utilized to scribe the map, the path of the existing map is enriched, the error in the map isadjusted and modified, and the preparation can be made for the travel plan of the user in advance.

Description

technical field [0001] The invention belongs to the technical field of electronic maps, and in particular relates to a method for generating high-precision map paths. Background technique [0002] An electronic map is a visual product that displays map data in a variety of media based on a digital map. According to the actual needs, the electronic map needs to have a high degree of integration and meet certain interactivity in the process of being used by people. Therefore, the electronic map used by people can usually cover all directions. The data of the electronic map covers many types and can be widely used in many fields. Electronic map production must require comprehensive and accurate map element data, in which the map database plays a central role. Using various basic geographic data, combined with other relevant data, according to production requirements, various data are carefully divided and processed, and graded in advance, and then according to actual needs,...
