And the user can control a plurality of vehicle-mounted image terminals through a plurality of control terminals, and also can control a plurality of vehicle-mounted image terminals through one control terminal.
By establishing network connections between the control terminal and the vehicle-mounted image terminal and the server respectively, illegal control by external network intrusion can be avoided when the control terminal, the server and the vehicle-mounted image terminal are started. Thus, the safety of the control terminal, the server and the vehicle-mounted image terminal during starting operation can be improved.
S202, generating a control instruction based on the control terminal and the network connection between the vehicle-mounted image terminal and the server, and forwarding the control instruction to the vehicle-mounted image terminal through the server for shooting.
After the control terminal and the vehicle-mounted image terminal are respectively connected with the server through the network, the control terminal can send data or instructions to the vehicle-mounted image terminal based on the server to control the vehicle-mounted image terminal to execute corresponding actions. The control instruction may be an instruction generated correspondingly according to a request issued by a user to acquire vehicle driving information, and the vehicle driving information may include a vehicle driving state, driving information of the vehicle and surrounding vehicles, driving information of the vehicle and the surrounding of a road, and the like, for example: the distance between the user's vehicle and an adjacent vehicle in front of the left lane.

When the verification is passed, the network connection between the vehicle-mounted image terminal and the server and the network connection between the control terminal and the server can be respectively established.
The vehicle-mounted image terminal can be provided with a video shooting device, and the video shooting device comprises a camera (or a WEBCAM), a camera and the like. The camera is also called a computer camera, a computer eye, an electronic eye, and the like, is a video input device, is widely applied to the aspects of real-time monitoring and the like, and is mainly used for collecting vehicle driving information in the embodiment.
The camera may be a 2D (dimension) camera, where the 2D represents a two-dimensional space, and an image frame in the camera has two dimensions, i.e., an upper dimension, a lower dimension, a left dimension, and a right dimension. The camera can also be a 3D camera, the 3D represents a three-dimensional space, and an image picture in the camera can show up-down, left-right and front-back dimensions to form an image picture with three-dimensional vision. The camera can be wide-angle camera, when the camera detected that a plurality of objects appear in field of vision scope, can open wide-angle camera and shoot, and the quantity of a plurality of objects can be as required and carry out preset.
When the control terminal sends a control instruction to the vehicle-mounted image terminal, the vehicle-mounted image terminal can control the camera to shoot a shooting picture which is required to be obtained by a user, and the obtained shooting picture can be a video picture in a period of time or one or more image pictures.
S203, the receiving server processes the vehicle-mounted image shot by the vehicle-mounted image terminal to obtain a target image.

After the vehicle-mounted image terminal acquires the vehicle-mounted image, the vehicle-mounted image terminal can store the vehicle-mounted image in a corresponding storage area and then upload the stored vehicle-mounted image. Or uploading the acquired vehicle-mounted image to a server in real time. The mode of storing and uploading firstly can facilitate the user to directly obtain the vehicle-mounted image at the vehicle-mounted image terminal.
Specifically, the in-vehicle image terminal is controlled to forward the captured in-vehicle image to the server before receiving the target image.
The vehicle-mounted image captured by the camera on the vehicle-mounted image terminal can comprise a target image to be acquired by the user, and can also comprise images beyond the range required to be acquired by the user, such as: the user only wants to send a control instruction through the control terminal to control the camera to acquire a target image which is acquired by rotating the camera towards the left side of the vehicle in 5 o ' clock to 5 o ' clock and 10 min clock in the afternoon, but actually, the camera acquires vehicle-mounted images in a plurality of directions between 5 o ' clock and 10 min clock.
The control instruction comprises preset receiving conditions, and the receiving server processes the vehicle-mounted image according to the preset receiving conditions to obtain the target image.
The server may be configured with an image recognition service, and the image recognition service may recognize the vehicle-mounted image to obtain a target image, for example: and selecting an image at a certain moment in the vehicle-mounted image to obtain a target image which a user wants to obtain, and sending the target image to the control terminal.
When the vehicle-mounted image shot by the vehicle-mounted image terminal is inconsistent with the vehicle-mounted image which the user wants to acquire, the vehicle-mounted image shot by the vehicle-mounted image terminal can be sent to the server, image recognition is carried out on the vehicle-mounted image in the server, and the target image which the user wants to acquire is screened out. The image that the user wants to obtain may also be included in the control instruction, and when the control terminal sends the control instruction to the server, the server may extract and store the image that the user wants to obtain in the control instruction. When the vehicle-mounted image terminal shoots the vehicle-mounted image and sends the vehicle-mounted image to the server, the vehicle-mounted image terminal can also store the vehicle-mounted image and then can compare the vehicle-mounted image with the server, screen out the image which the user wants to obtain as a target image and send the target image to the control terminal.
Of course, if the vehicle-mounted image captured by the vehicle-mounted image terminal is consistent with the image that the user wants to acquire, the vehicle-mounted image can be directly taken as the target image and transferred to the control terminal through the server.
