Three-dimensional map generation method, device, vehicle navigation device and unmanned vehicle

Abstract

The embodiment of the present invention discloses a three-dimensional map generation method, device, vehicle navigation equipment, and unmanned vehicle; after the embodiment of the present invention collects the road information and relative position information of the vehicle, the relative position information includes the relative position of the surrounding environment of the vehicle. For the position information of the vehicle, the coordinate information of the map element corresponding to the road information is marked in the relative position information, and the relative level of the map element is marked according to the coordinate information to obtain the two-dimensional map data. Then, based on the two-dimensional map data, use The road information and the relative position information build a three-dimensional model of the road where the vehicle is located, and according to the coordinate information and relative levels of the map elements, the map elements are hierarchically matched in the three-dimensional model to generate a three-dimensional map; the three-dimensional map can be greatly improved. the quality of.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for generating a three-dimensional map, a vehicle navigation device and an unmanned vehicle. Background technique [0002] In recent years, with the development of autonomous driving technology, the related vehicle navigation technology has also made great progress. The existing vehicle navigation technology mainly uses high-precision three-dimensional maps to obtain accurate vehicle location information and navigation information. The precision 3D map is still generated manually or automatically. [0003] During the research and practice of the prior art, the inventors of the present invention found that manual labeling of 3D maps is inefficient, poor in accuracy, and manual labeling in a 3D environment is difficult, while using algorithms to automatically label 3D maps has errors The higher the rate, the less stable the accuracy of the 3D map, and th...
