Abstract

The embodiment of the invention provides a base map processing method and device and electronic equipment, and the method comprises the steps: carrying out the partitioning of a first base map and a second base map, and obtaining the same number of first base map blocks and second base map blocks; the association relationship between the first base map blocks and the second base map blocks is established, base map block pairs are formed, and each base map block pair comprises one first base map block and one second base map block; screening a target base map block pair from the base map block pairs; performing pose optimization on each target base map block pair; according to each optimized target base map block pair, carrying out pose optimization on the base map block pair except the target base map block in each base map block to obtain a first optimized base map and a second optimized base map; and fusing the first optimized base map and the second optimized base map to generate the target base map, so that the problem of double images of the base map can be effectively solved, and the precision of the manufactured high-precision map is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of unmanned driving, and in particular, to a base map processing method and device. Background technique [0002] At present, high-precision maps, as the prior knowledge of unmanned driving, play a pivotal role in the field of autonomous driving. At present, the production process of high-precision maps includes data collection, pose optimization, base map generation, element extraction, manual production and other processes. [0003] Basemap is the key to ensure high-precision map production. In actual production, in the weak GPS (Global Positioning System, global positioning system) scene, the problem of feature loss in the collected data is prone to occur due to the interference of dynamic obstacles in the shooting location, repeated scenes, etc., and the feature loss in the collected data will lead to position The attitude optimization failed, which eventually led to ghosting of ...
