The embodiment of the invention discloses a deviation rectifying method and device for a high-precision map, electronic equipment and a storage medium, and relates to the technical field of automaticdriving. The method comprises the steps of constructing a first data structure corresponding to first track information, constructing a second data structure corresponding to the first track information and the second track information; determining deviation rectification information of the original high-precision map according to the first data structure and the second data structure, generatingthe target high-precision map according to the deviation rectification information and the original high-precision map, constructing the data structure by collecting the track information, and determining the deviation rectification information according to the data structure, so that the waste of labor cost when the original high-precision map is adjusted in a manual comparison mode in related technologies is avoided; and when the data structure is constructed and the deviation rectification information is determined according to the data structure, the track information when the original high-precision map is determined is reserved, so that the obtained deviation rectification information can more accurately reflect the possible change condition of the original high-precision map, and the accuracy and reliability of the deviation rectification information are improved.
Description
technical field [0001] The embodiments of the present disclosure relate to the technical field of data processing, in particular to the technical field of automatic driving, and in particular to a high-precision map deviation correction method and device, electronic equipment, and a storage medium. Background technique [0002] With the development of autonomous driving technology, the requirements for high-precision maps are getting higher and higher. In order to meet the accuracy and reliability of high-precision maps, high-precision maps need to be updated. [0003] In the prior art, the newly collected trajectory information is compared with the original high-precision map mainly by manual means, so as to adjust the coordinate information of at least some points in the original high-precision map based on the newly collected trajectory information . [0004] However, in the process of implementing the present disclosure, the inventors have found at least the following p...
