Method and equipment for updating map data

Abstract

The invention discloses a method and a device of updating map data, wherein, each place in the map not only is related to geographic data, but also is related to at least one scene image pictured in the place. The method comprises: collecting video data and the geographic data representing location of the place in each place; extracting a representative area representing the place from the scene image based on predetermined standards and making the representative area related to the place; extracting an image pictured in the place from the video data based on the location of the place; matching the representative area and the extracted image and generating a matching result; in the condition that the matching result shows the map data need to be updated, making the image matched with the representative area as an update image to update the scene image. Making use of the invention can rapidly update the map data, so as to provide up-to-date geographic data for users.

Description

technical field [0001] The invention relates to geographic information processing technology, in particular to a method and device for rapidly updating map data, so as to provide users with the latest geographic information. Background technique [0002] Now maps play a very important role in our daily life. For people traveling, the map can tell people along which route to reach the destination, and can tell people other information related to the destination.
