Abstract

The invention discloses a road scene map building method and device. The method comprises the steps that an editing instruction editing vector map data is received, wherein the editing instruction isused for indicating that target operation is executed on an operation object in the vector map data; the operation object is subjected to target operation in a two-dimensional scene or a three-dimensional scene according to the editing instruction, and an operation result is obtained, wherein coordinates in the two-dimensional scene or the three-dimensional scene has the mapping relation; information of the operation object in the vector map data is updated according to the operation result, updated information of the operation object in the vector map data is obtained; according to the updated information, the information of the operation object in a target scene is updated, wherein the target scene is the scene not executing target operation on the operation object in the three-dimensional scene and the two-dimensional scene. Accordingly, the technical problem that the built road scene map is low in precision is solved.

Description

technical field [0001] The present invention relates to the field of map construction, in particular to a method and device for constructing a road scene map. Background technique [0002] With the development of autonomous driving technology, high-precision maps have gradually become an indispensable part of the entire technical process. High-precision maps can not only provide road scenes with higher absolute accuracy, but also contain rich and detailed road traffic information elements, so as to provide accurate data sources for self-driving vehicles, so that they can accurately judge the surrounding environment and make appropriate driving decisions Strategy. Traditional 3D maps mostly use digital maps as basic data, combined with road image information and field measurement data for artificial construction. Its modeling method is relatively complicated, which requires a lot of manpower and time, and the final road scene has low precision and large human error. At pre...
