Abstract

This application provides a method for verifying heterogeneous map matching data and a vehicle. The method includes: acquiring heterogeneous map matching data, wherein the heterogeneous map matching data represents the matching result obtained after matching map data from at least two sources; performing multi-dimensional quality verification on the heterogeneous map matching data to obtain a multi-dimensional verification result, wherein the multi-dimensional quality verification includes at least two of the following: link interruption verification, link duplication verification, geometric consistency verification, and topology rationality verification; evaluating the multi-dimensional verification result to generate a target verification result corresponding to the heterogeneous map matching data, wherein the target verification result is used to indicate whether the matching accuracy of the heterogeneous map matching data meets a preset accuracy. This application solves the technical problem of low verification accuracy of heterogeneous map matching data in related technologies.
