Abstract

A traffic information update method includes recognizing, by a terminal, a first traffic sign from a road image; detecting whether traffic information of the terminal includes first alert information corresponding to the first traffic sign; if the traffic information of the terminal does not include the first alert information, generating a traffic sign adding instruction corresponding to the first traffic sign; and sending the traffic sign adding instruction to a server. After finding a new traffic sign, the terminal may report a content indication and a location indication of the traffic sign to the server such that the server can directly update traffic information according to the information reported by the terminal.

Claims

1. A traffic information update method, comprising:

receiving, by a first terminal, a road image from at least one other device according to a preset condition when the first terminal does not comprise a real-time imaging feature, wherein the other device in communication with the first terminal, and wherein the road image comprises a first traffic sign;

recognizing, by the first terminal, the first traffic sign in the road image;

obtaining, by the first terminal, a location of the first traffic sign and content of the first traffic sign;

retrieving, by the first terminal, first traffic information stored on the first terminal;

detecting, by the first terminal, whether the first traffic information comprises first alert information corresponding to the first traffic sign at the location, wherein the first alert information comprises alert content for the location of the first traffic sign;

determining, by the first terminal, that the first traffic information at the first terminal comprises alert information for the location of the first traffic sign;

determining, by the first terminal, that the alert content for the location of the first traffic sign does not match the content of the first traffic sign;

generating, by the first terminal, an instruction to add second alert information at a server when the alert content for the location of the first traffic sign does not match the content of the first traffic sign, wherein the second alert information comprises the location of the first traffic sign and the content of the first traffic sign; and

sending, by the first terminal, the instruction to the server in response to generating the instruction, wherein the instruction instructs the server to add the second alert information to second traffic information at the server.

2. The method according claim 1, wherein generating, by the first terminal, the instruction to add the second alert information comprises generating, by the first terminal, the instruction to add the content of the first traffic sign.

3. The method according to claim 2, wherein before generating, by the first terminal, the instruction to add the second alert information, the method further comprises determining, by the first terminal, a pointing direction of the first traffic sign, and wherein generating, by the first terminal, the instruction to add the second alert information comprises generating, by the first terminal, the instruction to add the second alert information that comprises the content and the pointing direction of the first traffic sign.

4. The method according to claim 1, further comprising generating, by the first terminal, the first alert information when the first traffic information at the first terminal does not comprise the first alert information.

5. A system for updating traffic information at a server, comprising:

a first terminal in communication with the server, wherein the first terminal comprises;

a processor;

an input device configured to receive a road image from at least one other device according to a preset condition when the first terminal does not comprise a real-time imaging feature, wherein the other device in communication with the first terminal, and wherein the road image comprises a first traffic sign;

a communications device; and

a memory configured to store first traffic information at the first terminal,

wherein the processor, the input device, the communications device, and the memory communicate via a bus, and

wherein the processor is configured to;

recognize the first traffic sign in the road image;

obtain a location of the first traffic sign and content of the first traffic sign;

retrieve the first traffic information;

detect whether the first traffic information comprises first alert information corresponding to the first traffic sign at the location, wherein the first alert information comprises alert content for the location of the first traffic sign;

determine that the first traffic information at the first terminal comprises alert information for the location of the first traffic sign;

determine that the alert content for the location of the first traffic sign does not match the content of the first traffic sign;

generate an instruction to add second alert information at the server when the alert content for the location of the first traffic sign does not match the content of the first traffic sign, wherein the second alert information comprises the location of the first traffic sign and the content of the first traffic sign;

send the instruction to the server in response to generating the instruction, wherein the instruction instructs the server to add the second alert information to second traffic information at the server; and

a second terminal in communication with the server and configured to;

receive a notification from the server that the second traffic information comprises incremental alert information in response to sending the instruction by the first terminal to the server and the server does not include the content of the first traffic sign, wherein the incremental alert information comprises the second alert information;

transmit a request to receive the incremental alert information after receiving the notification from the server, wherein the second terminal comprises third traffic information;

receive the incremental alert information from the server in response to transmitting the request to the server to receive the incremental alert information; and

add the incremental alert information to the third traffic information to update the third traffic information.

6. The system according to claim 5, wherein the processor is further configured to:

generate the first alert information; and

add the first alert information to the first traffic information of the first terminal when the first traffic information at the first terminal does not comprise the first alert information.

7. A terminal comprising:

an input device configured to receive a road image from at least one other device according to a preset condition when the terminal does not comprise a real-time imaging feature, wherein the terminal is configured to communicate with the other device, and wherein the road image comprises a first traffic sign;
