A method and system for safe driving of vehicles based on Internet of Vehicles

Abstract

The present invention provides a vehicle safety driving method and system based on the 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 during driving. The geographical location information on the vehicle side, in the judgment and correction stage of the safe traffic sign, the cloud traffic management server judges whether the image of the safe traffic sign has been illegally altered or tampered with based on the digital watermark information, and compares the geographical location information on the vehicle side with the information contained in the digital watermark information. The geographical location information of the safety traffic sign to be placed is to solve the problem of judging and correcting the image of the safety traffic sign after the placement position is incorrect or illegally moved, thereby avoiding the problem of self-driving cars being placed in the wrong position or being illegally placed on the safety traffic sign. When moving the location, there is a problem of false actions at places or road sections where actions should not be taken.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a method and system for safe driving of vehicles based on Internet of Vehicles. 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. The main signs include speed limit signs, warning signs, prohibition signs, instruction signs, road signs, etc. Among them, the speed limit signs are divided into signs that limit the minimum speed and signs that limit the maximum speed. Cars on the road are not allowed to drive at too low speed, the purpose is to allow cars to pass quickly, make traffic faster and avoid congestion. The purpose of limiting the maximum speed is to l...

Problems solved by technology

But unfortunately, malicious attackers only need to illegally paste stickers on traffic signs to change the content and meaning of the traffic signs, and they can deceive the vision-based perception system of self-driving cars, so that self-driving cars make misjudgments

In addition, malicious attackers can also illegally move the real traffic sign to another location, so that after the self-driving car recognizes the traffic sign, it will act according to the instructions of the traffic sign at the place or road section where it should not take action.

These possible attacks are very dangerous for self-driving cars and may cause significant personal or property damage
