Abstract

The embodiment of the invention discloses an electronic navigation map quality detection method and device. The method comprises the steps of obtaining a to-be-detected electronic navigation map; obtaining a plurality of pieces of pose information and corresponding positioning moments of the vehicle in the process of driving in the scene corresponding to the electronic navigation map; obtaining perception data determined by the vehicle in the driving process, wherein the collection moment corresponding to each road image and the positioning moment corresponding to each pose information have acorresponding relation; for each pose information, determining map semantic data corresponding to the pose information from the electronic navigation map; aiming at each pose information, based on themap position information of the map semantic data corresponding to the pose information in the electronic navigation map and / or the observation position information of the sensing data correspondingto the pose information in the corresponding road image, determining a quality detection result of the electronic navigation map, thereby achieving detection of the quality problem of the electronic navigation map.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for detecting the quality of an electronic navigation map. Background technique [0002] In the field of unmanned driving, the decision-making and planning technology of the vehicle's driving route often relies on the electronic navigation map used by the vehicle. Especially for the positioning of unmanned vehicles, the position accuracy of the electronic navigation map determines the accuracy of the positioning results of unmanned vehicles to a certain extent. [0003] In related technologies, during the creation process of the electronic navigation map, quality problems often occur in the electronic navigation map, such as bending and breaking of lane lines in the electronic navigation map, vibration of lane line elevation, and tilting of street light poles. The above-mentioned quality problems, to a certain extent, affect the accuracy of...
