ETC charging method, vehicle-mounted communication device and ETC platform

The invention discloses an ETC charging method, a vehicle-mounted communication device and an ETC platform, and the charging method can comprise the following steps that the vehicle-mounted communication device triggers an image collection device on a vehicle to carry out the image collection of a current road where the vehicle is located; and the vehicle-mounted communication device identifies and confirms that the acquired image contains the ETC information, and sends the corresponding vehicle information to the ETC platform, so that the ETC platform charges the vehicle. According to the ETCcharging method, the vehicle can be charged in advance through the built-in communication device and the built-in image acquisition device of the vehicle, so that the time required for communicationbetween an OBU and a microwave antenna on an ETC special lane in a traditional charging system is saved, the time for the vehicle to pass through a toll station is greatly shortened, the situation ofroad congestion is avoided,
