Map fusion method and device, server and storage medium

Abstract

The embodiment of the invention provides a map fusion method and device, a server and a storage medium, and the method comprises the steps: obtaining first three-dimensional map data and second three-dimensional map data, and for at least two first semantic elements in the first three-dimensional map data, determining at least two matched second semantic elements in the second three-dimensional map data, determining first relative information between the at least two first semantic elements, determining second relative information between the at least two second semantic elements, and optimizing the first three-dimensional map data and the second three-dimensional map data according to the first relative information and the second relative information; and performing map fusion on the optimized first three-dimensional map data and the optimized second three-dimensional map data. Through the embodiment of the invention, the optimization of the three-dimensional map data is realized, themap fusion process is simplified, the calculation amount is reduced, and the map fusion precision and efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of maps, in particular to a map fusion method and device, a server, and a storage medium. Background technique [0002] With the development of smart cars, the accuracy of car positioning and perception is getting higher and higher, which requires maps with higher precision and larger coverage. In order to meet the high requirements of cars for maps, maps can be fused to get more accurate map. [0003] However, in the prior art, when performing 3D map fusion, due to differences in the accuracy or collected data of different maps, there will be errors between different maps, resulting in complex calculations during map fusion, increasing the amount of calculations, and reducing This reduces the efficiency of map fusion, and it is difficult to guarantee the accuracy of the fused map. Contents of the invention [0004] In view of the above problems, a method, device, server, and storage medium for m...
