A method and system for correcting safety traffic signs based on Internet of Vehicles

Abstract

The present invention provides a safety traffic sign correction method and system based on Internet of Vehicles, which generates safe traffic signs by embedding digital watermark information in ordinary traffic sign images, and collects image information of traffic signs while driving. Collect the geographical location information of the vehicle; the cloud traffic management server not only judges whether the image of the safe traffic sign has been illegally altered or tampered with based on the digital watermark information, but also compares the geographical location information and digital watermark information of the vehicle in the judgment and correction stage of the safety traffic sign The geographic location information of the safety traffic sign to be placed contained in it is used to solve the problem of judging the error of the safety traffic sign image after the placement position is incorrect or illegally moved; the vehicle side also finds the traffic sign on the road at the actual location, However, if no traffic sign is found at the corresponding position in the map information or the content of the traffic sign found is wrong, check, verify and correct it.
