Abstract

The invention provides a method, a device and a system for map quality inspection, and a storage medium. The method comprises: obtaining thermodynamic values of all regions on the map; wherein the thermodynamic value of each area is used for representing the reliability of the corresponding area; wherein the thermodynamic value and a reliable value of an area corresponding to the thermodynamic value are in a negative correlation mapping relation; determining an area of which the thermal value is greater than a preset threshold as a target area; and displaying the target area on the map. Therefore, map quality inspection personnel can quickly determine a problematic area, the area is corrected, the manual detection time is shortened, and the labor cost is reduced. The map production time isshortened, and the map production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a map quality inspection method, device, system and storage medium. Background technique [0002] With the development of automobile technology, unmanned vehicles have begun to be applied and developed. During the driving process of the unmanned vehicle, it is necessary to provide a high-precision map for the unmanned vehicle, so that the unmanned vehicle can automatically drive according to the high-precision map. [0003] In the prior art, it is necessary to detect the generated high-precision map to determine the difference between the generated high-precision map and the real environment, so as to adjust the generated high-precision map. [0004] However, in the prior art, manual detection is generally used to detect the generated high-precision map. Since the high-precision map contains a lot of information, manual detection takes a long time and the labor...
