2) And comparing the traffic rule image information with the new traffic rule image information base to judge whether the traffic rule image information is the new traffic rule image information.
Specifically, the traffic regulation image information in the image information of the road ahead acquired by the vehicle-mounted camera device is compared with a pre-stored new traffic regulation image information base to determine whether the traffic regulation image information in the image information is the new traffic regulation image information. In another embodiment of the present invention, the determining whether the traffic rule image information is the new traffic rule image information includes the following steps:
A) sending the traffic rule image information to a cloud server; and the cloud server judges according to the traffic rule image information.
Specifically, image information is sent from the in-vehicle terminal to the cloud server. The vehicle-mounted terminal is connected with the cloud server in a WiFi, 3G or 4G mode. And the cloud server judges whether the traffic rule image information is new traffic rule image information or not according to the traffic rule image information.
B) And receiving a judgment result fed back by the cloud server.
Specifically, the vehicle-mounted terminal receives a judgment result of whether the traffic rule image information sent by the cloud server is new traffic rule image information.
In another embodiment of the present invention, whether the driving is an illegal driving is determined according to the traffic rule image information, and if so, a reminding message is sent.

The advancing road is a current driving road of the vehicle, and the vehicle-mounted camera device acquires image information of the current driving road of the vehicle.
In another embodiment of the present invention, the forward road is another road adjacent to the current driving road of the vehicle, and the vehicle can enter the forward road through a left turn or a right turn.
The identification module 22 is configured to identify traffic regulation image information in the image information.
Specifically, the identification module 22 identifies traffic regulation image information in the image information based on an image identification algorithm by analyzing the acquired image information, wherein the traffic regulation image information includes image information corresponding to the regulation of the traffic regulation. For example, traffic regulations specify that vehicles should pass according to traffic signals, i.e., traffic regulation image information. The traffic signals include traffic lights, traffic signs, traffic sign lines, and traffic police commands. For example, the traffic regulation stipulates that when a pedestrian passes through a pedestrian crossing, the pedestrian should stop and give way, and an image of the pedestrian on a sidewalk is traffic regulation image information. The recognition module 22 analyzing the captured image information includes recognizing traffic regulation image information in the image information based on a specific image recognition algorithm. The image recognition algorithm includes, but is not limited to, target recognition algorithms such as Fast Rcnn algorithm (full name: Fast Regions with CNNs features) and Yolo algorithm (full name: You Only Look Once) based on deep learning, or other types of image target recognition algorithms.
The judging module 23 is configured to judge whether the traffic rule image information is new traffic rule image information; if yes, sending out a reminding message. .
Specifically, the new traffic regulation image information is the traffic regulation image information covered by the newly issued traffic regulation. Which is a new and different traffic regulation compared with the original traffic regulation. For example, newly issued traffic regulations newly stipulate that a lane is a special lane, and only a prescribed vehicle is permitted to pass through the special lane, and other vehicles cannot enter the special lane to travel. The original traffic regulation does not make a regulation, and the image of the road with the special lane is the new traffic regulation image information. The judging module 23 compares the traffic rule image information with the new traffic rule image information to analyze whether the traffic rule image information is the new traffic rule image information.
In an embodiment of the present invention, when it is determined that the traffic rule image information is the new traffic rule image information based on that the forward road is the current driving road, the determining module 23 immediately sends a prompting message.
In another embodiment of the present invention, based on that the road ahead is another road close to the current driving road of the vehicle, before the vehicle drives into the road ahead, the determining module 23 sends a prompting message when the traffic rule image information is determined to be the new traffic rule image information.
