Method, device and equipment used for marking map

Abstract

The invention discloses a method and a device used for making a map. The method comprises the following steps of responding to the operation of detecting that a user is in a selected area to be markedon the map to be marked, and finding geographical position information corresponding to the area to be marked in the geographical position information list corresponding to the stored map to be marked; acquiring a road image sequence and a track point set collected by a in-vehicle camera, wherein each track point in the track point set is recorded when the in-vehicle camera collects each frame ofroad images in the road image sequence; according to the geographical position information of the area to be marked and the track point set corresponding to the road image sequence, extracting a target image frame corresponding to the area to be marked from the road image sequence; and responding to a condition that that a marking operation which is performed by a user reference target image frame on a marked object in the area to be marked is detected and generating a marked file used for storing the position parameter of the marked object. In the invention, map marking efficiency can be increased.

Description

technical field [0001] The present application relates to the technical field of computers, in particular to the technical field of electronic maps, and in particular to methods, devices and equipment for marking maps. Background technique [0002] With the development of science and technology, the application fields of maps are becoming more and more extensive. For example, in the field of autonomous driving, vehicles can use high-precision maps for positioning and route planning. In order to ensure the safe driving of vehicles, lane lines, road traffic signs and other landmarks need to be marked on the map, so that the autonomous driving vehicle can accurately calculate the road environment and driving path and accurately control the driving of the vehicle. [0003] At present, landmarks in high-precision maps usually rely on manual auxiliary labeling. Annotators find out the corresponding street view data based on experience, and mark it against the map. This method n...

AI Technical Summary

Problems solved by technology

This method needs to use multiple applications such as the application of generating maps and the application of searching for street view data to work together, and has high requirements for labeling personnel, who need to be familiar with the marked area in order to correctly retrieve the referenced street view data. The labeling efficiency and accuracy of precision maps need to be improved
