The preset speed interval may be a speed interval in which the preset vehicle runs safely; the preset acceleration may be a predetermined acceleration when the vehicle is traveling safely.
Specifically, when the running speed of the vehicle is not within a preset speed interval or the running acceleration is greater than a preset acceleration, it may be considered that the vehicle may perform an unexpected speed action, and the camera recording function needs to be started to record the running condition of the vehicle.
And 230, comparing key information of each video frame of the original recorded video, and extracting key information frames according to the comparison result, wherein the key information comprises lane line information and vehicle position information.

Specifically, in the comparison process, the key information of the target video frame and the comparison reference frame may appear for many times, which does not meet the preset approximate judgment condition, and then a plurality of key information frames are determined, so that the positions of the comparison reference frame are updated continuously until the tail video frame of the original recorded video is compared, and then all the key information frames in the video can be determined.
Step 270, if the key information of the comparison reference frame and all the subsequent video frames meet the preset approximate determination condition, determining the comparison reference frame as a key information frame.
Specifically, if the key information of the reference frame and all the subsequent video frames are compared to meet the preset approximate judgment condition, the content of all the frames of the video is considered to be approximate, and only the first video frame is required to be determined as the key information frame.
Step 280, if the collision sensor signal indicates that the vehicle collides, uploading the key information frame to the server.
Specifically, if the collision sensor signal is a collision signal, it indicates that the vehicle may collide, and it is necessary to upload a key information frame to the server, and if the collision sensor signal is not sent, it indicates that the vehicle does not collide, and it is unnecessary to upload the key information frame.

The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.
It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps described in the present invention may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present invention are achieved, and the present invention is not limited herein.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
Claims (10)
1. A video transmission method in a highway scene, comprising:
acquiring a speed condition of the vehicle in response to the vehicle entering a highway scene, wherein the speed condition comprises a running speed and a running acceleration;

and uploading the key information frame to a server according to the collision sensor signal.
2. The method of claim 1, wherein the acquiring the speed condition of the vehicle in response to the vehicle entering the highway scene comprises:
acquiring a vehicle position by using a GPS module, and judging whether the vehicle enters a highway scene or not according to the vehicle position;
if yes, a speed sensor and an acceleration sensor are started, a running speed and a running acceleration are obtained, and the running speed and the running acceleration are determined to be the speed condition of the vehicle.
3. The method according to claim 1, wherein the step of controlling the on/off state of the camera recording function according to the speed condition of the vehicle, and extracting key information frames from the original recorded video obtained by parallel recording comprises:
if the running speed is not in the preset speed interval or the running acceleration is larger than the preset acceleration, starting a camera recording function, and recording to obtain an original recorded video;
and comparing the key information of each video frame of the original recorded video, and extracting the key information frame according to the comparison result, wherein the key information comprises lane line information and vehicle position information.
4. The method of claim 3, wherein the comparing the key information of each video frame of the original recorded video, and extracting the key information frame according to the comparison result, comprises:
determining a first video frame of the original recorded video as a comparison reference frame, and sequentially comparing a subsequent video frame of the comparison reference frame with the comparison reference frame in key information;
under the condition that any target video frame in the follow-up video frames is compared, if the key information of the target video frame and the comparison reference frame does not accord with a preset approximate judgment condition, determining the target video frame as a key information frame;
and updating the key information frame into the comparison reference frame, and executing the step of comparing the subsequent video frames of the comparison reference frame with the comparison reference frame in sequence until the tail video frame of the original recorded video is compared.
5. The method as recited in claim 4, further comprising:
and if the key information of the comparison reference frame and all the subsequent video frames accords with the preset approximate judging condition, determining the comparison reference frame as a key information frame.
6. The method of claim 1, wherein uploading the key information frame to the server according to the collision sensor signal comprises:
and if the collision sensor signal represents that the vehicle collides, uploading the key information frame to the server.
7. The method of claim 1, wherein after uploading the key information frame to a server according to the collision sensor signal, the method further comprises:
and judging the safety state of the vehicle according to the key information frame, and alarming according to the basic information and the running information of the vehicle if the safety state of the vehicle represents that the vehicle is unsafe.
8. A video transmission apparatus in a highway scene, comprising:
the speed acquisition module is used for responding to the situation that the vehicle enters the expressway, and acquiring the speed condition of the vehicle, wherein the speed condition comprises the running speed and the running acceleration;
the video processing module is used for controlling the opening and closing states of the camera recording function according to the speed condition of the vehicle and extracting key information frames from the recorded original recorded video, wherein the key information frames are used for representing the change condition of lane line information and/or vehicle position information;
and the uploading module is used for uploading the key information frame to a server according to the collision sensor signal.
9. An electronic device, the electronic device comprising:
at least one processor; and
a memory communicatively coupled to the at least one processor; wherein,
the memory stores a computer program executable by the at least one processor to enable the at least one processor to perform a video transmission method in a highway scene according to any one of claims 1 to 7.
10. A computer readable storage medium storing computer instructions for causing a processor to perform the video transmission method in a highway scene according to any one of claims 1-7.
