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 present disclosure provides a map quality inspection method, device, electronic device and storage medium, which relate to the technical field of artificial intelligence, and in particular, to electronic map technology. The specific implementation scheme is: obtaining the road map of the current version and the road map of the previous version; Road network differential data; based on the road network differential data of the current version of the road map relative to the previous version of the road map, the current version of the road map is checked for quality. The embodiments of the present application can not only reduce labor costs and improve quality inspection efficiency, but also improve the accuracy of map quality inspection, making map quality inspection more targeted.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence technology, and further relates to electronic map technology, in particular to a map quality inspection method, device, electronic device and storage medium. Background technique [0002] When generating an electronic map, it is necessary to collect the image information of the travel lane, analyze the structured data of the travel lane according to the image information of the travel lane, and generate a high-precision road map of the travel lane according to the structured data of the travel lane. The structured data of all traffic lanes in an area can form a high-precision road map of the area or area. [0003] Before releasing a high-precision road map, it is necessary to conduct quality inspection on the high-precision road map. The current map quality inspection usually adopts the following two methods: 1) Automatic quality inspection by machine: This method can only detect ba...
