Abstract

The invention discloses a map detection method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining vehicle scene data of a real path corresponding to each map path in a to-be-detected map; wherein the vehicle scene data comprises sensing data acquired by at least one sensor installed on a real vehicle in the driving process of the real vehicle along the real path, and positioning truth value data of the real vehicle in the driving process; indicating a virtual vehicle to drive along a virtual path corresponding to the real path in a pre-established simulation platform, and determining simulation positioning data of the virtual vehicle in the driving process by using a preset positioning algorithm, the sensing data and a to-be-detected map; and detecting a to-be-detected map according to the simulation positioning data and the positioning truth value data. According to the embodiment, the map quality can be automatically, efficiently and accurately detected based on the simulation platform.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a map detection method and device. Background technique [0002] As the development direction of future automobiles, autonomous driving technology is developing rapidly and continuously improving around the world. High-precision maps are an essential part of large-scale deployment of autonomous driving, and their quality affects the maturity and reliability of autonomous driving technology. The development of autonomous driving technology has high requirements for the quality of high-precision maps. In the production or update process of high-precision maps, the quality of maps is mainly guaranteed by the experience of quality inspectors, that is, manual quality inspection. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The existing technology generally evaluates the accu...
