Problems solved by technology

[0002]In automatic driving technology, such as automatic parking system (Automated Parking System, APS), semantic map is an important part. Planning and other aspects play an important role. Semantic maps are usually constructed from a large number of semantic elements. However, the description of semantic elements in the existing technology is insufficient, which affects the accuracy of semantic maps and limits autonomous driving.

Abstract

The embodiment of the invention provides a map data processing method and device. The method comprises the following steps: acquiring map data; establishing a spherical coordinate system according to a first semantic element in the map data, and determining one or more second semantic elements in the map data according to the spherical coordinate system; establishing a plurality of height layers; for the one or more second semantic elements, determining a height layer to which the one or more second semantic elements belong, and determining projection information of the one or more second semantic elements projected to the height layer to which the one or more second semantic elements belong; and generating description information for the first semantic element according to the projection information. Through the embodiment of the invention, the optimization of the semantic element description is realized, the description information of the first semantic element is generated by combining the second semantic element, the content of the semantic element description is increased, the accuracy of the semantic map is improved, and the ability of automatic driving is further improved.

Description

technical field [0001] The invention relates to the field of map technology, in particular to a method and device for processing map data. Background technique [0002] In automatic driving technology, such as automatic parking system (Automated Parking System, APS), semantic map is an important part, which plays an important role in positioning, reference line generation and path planning. Semantic map is usually composed of a large number of However, the description of the semantic elements in the existing technology is insufficient, which affects the accuracy of the semantic map, and thus limits the automatic driving. Contents of the invention [0003] In view of the above problems, a map data processing method and device for overcoming the above problems or at least partially solving the above problems are proposed, including: [0004] A method for processing map data, the method comprising: [0005] Get map data; [0006] Establishing a spherical coordinate system ...
