Problems solved by technology

[0003] At present, global matching is mainly used in navigation. Each matching needs to calculate the connection paths of all road nodes in the global map, which consumes a lot of computing resources. When the global map is too large, it is even impossible to match. Therefore, there is an urgent need for more A road matching method that saves computing resources

Abstract

The invention relates to an artificial intelligence technology, and discloses a road matching method, which comprises the steps of segmenting GPS data to obtain segmented GPS data; encoding the segmented GPS data to obtain encoded GPS data; carrying out associated segmentation on the map data by utilizing the coded GPS data to obtain segmented map data; performing first screening analysis calculation by utilizing the segmented map data and the segmented GPS data to obtain a target longitude and latitude point set and a candidate starting point set; performing second screening analysis calculation by utilizing the segmented map data and the target longitude and latitude point set to obtain a candidate end point set; and performing calculation according to the candidate starting point set and the candidate terminal point set to obtain a target path. The invention also relates to a blockchain technology, and the segmented GPS data can be stored in the blockchain. The invention further provides a road matching device, electronic equipment and a computer storage medium. According to the method, computing resources required by road matching are saved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a road matching method, device, electronic equipment and readable storage medium. Background technique [0002] With the application of map navigation in people's life more and more widely, the accuracy of navigation and road matching has attracted more and more attention. [0003] At present, global matching is mainly used in navigation.
