Abstract

The present invention provides a V2X-based safety traffic sign errata method and system. The safety traffic sign is generated by embedding digital watermark information in an ordinary traffic sign image. When a vehicle is driving, when collecting image information of the traffic sign, the The geographic location information of the vehicle end, in the judgment and errata stage of the safety traffic sign, not only to judge whether the safety traffic sign image has been illegally altered or tampered with based on the digital watermark information, but also to compare the geographic location information of the vehicle end with the information contained in the digital watermark information. The geographic location information to be placed on the safety traffic sign, in order to solve the problem of judging and errata in the image of the safety traffic sign after the placement position is incorrect or illegally moved; If there is no traffic sign found at the corresponding location in the file or the content of the found traffic sign is wrong, check, verify and errata.

Description

technical field [0001] The present invention relates to the technical field of traffic sign correction and V2X Internet of Vehicles, in particular to a V2X-based safe traffic sign correction method and system. Background technique [0002] Traffic signs are road facilities that convey guidance, restrictions, warnings or instructions in words or symbols. Also known as road signs, road traffic signs. Traffic signs are an important measure to implement traffic management and ensure road traffic safety and smoothness. Traffic signs are divided into main signs and auxiliary signs. Among them, the main signs include speed limit signs, warning signs, prohibition signs, instruction signs, guide signs and so on. [0003] Vehicle wireless communication technology (Vehicle to Everything, V2X) is a new generation of information communication technology that connects vehicles with everything, and is a general term for a series of vehicle communication technologies. V2X mainly include...
