Abstract

The embodiment of the invention provides a map data processing method and device. The method comprises the following steps of acquiring map data; determining description information of a first semantic element in the map data, and determining a third semantic element matched with the first semantic element according to the description information of the first semantic element; the description information of the first semantic element being generated according to projection information of one or more second semantic elements projected to a height layer to which the second semantic elements belong, and the one or more second semantic elements being determined according to a spherical coordinate system established according to the first semantic element; and fusing the map data according to the first semantic element and the third semantic element. Through the method, optimization of map fusion is realized, the repeated part in the map data can be found through setting of the description information, accuracy of the found repeated part can be ensured, the map fusion effect is improved, and the automatic driving capability 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, and for semantic map, usually Map fusion will be involved. [0003] For example, when there are multiple map data for the same parking lot, or there are multiple collection results for the same area in a single map data for the same parking lot, the map data needs to be fused. [0004] However, in the existing map fusion technology, there may be problems that the repeated parts in the map data cannot be found or the repeated parts found are not accurate, which affects the effect of map fusion. Contents of the invention [0005] In view of the above problems, a map data processing meth...
