Problems solved by technology

[0003] Before the high-precision road map is released, it is necessary to perform quality inspection on the high-precision road map. The current map quality inspection usually adopts the following two methods: 1) Machine-automated quality inspection: this method can only detect batch problems, It is impossible to test the road type and the rationality of the display, and it is also impossible to test the drawing effect. For example, if a certain road is deformed, the machine cannot accurately identify it; 2) Manual sampling quality inspection: This method uses pure Manually sample and drag the map to confirm whether there is a problem with the map drawing for each area; this is time-consuming and labor-intensive, and it is not targeted, that is, the area of ​​quality inspection may not have any changes, and the changed area is not in the random inspection in the sample, resulting in regions that are not detectable at all for the change

Abstract

The invention provides a map quality inspection method and device, electronic equipment and a storage medium, and relates to the technical field of artificial intelligence, in particular to an electronic map technology. According to the specific implementation scheme, the method comprises the steps of obtaining a road map of a current version and a road map of a previous version; comparing the road map of the current version with the road map of the previous version to obtain road network differential data of the road map of the current version relative to the road map of the previous version; and carrying out quality inspection on the road map of the current version based on the road network differential data of the road map of the current version relative to the road map of the previous version. The embodiment of the invention not only can reduce the labor cost and improve the quality inspection efficiency, but also can improve the accuracy of map quality inspection, so that the map quality inspection is more targeted.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and further relates to electronic map technology, in particular to a map quality inspection method, device, electronic equipment and storage medium. Background technique [0002] When generating an electronic map, it is necessary to collect the image information of the traffic lane, analyze the structured data of the traffic lane according to the image information of the traffic lane, and generate a high-precision road map of the traffic lane based on the structured data of the traffic lane. The structured data of all traffic lanes in the area can constitute a high-precision road map of the area or region. [0003] Before the high-precision road map is released, it is necessary to perform quality inspection on the high-precision road map. The current map quality inspection usually adopts the following two methods: 1) Machine-automated quality inspection: this method can o...
