Embodiment 1
[0080] Please refer to figure 1 , Embodiment 1 of the present invention is:
[0081] A vehicle early warning method, comprising the steps of:
[0082] S1. Obtain video image information within a preset range of the vehicle. The preset range of the vehicle includes the front of the vehicle, the rear of the vehicle, and the range of a few meters or more than ten meters on both sides of the vehicle. The specific range can be set according to needs.
[0083] S2. Determine whether there is a moving object in the video image information; if yes, execute step S3; if not, discard the video image information. In this embodiment, step S2 specifically includes: S21. Obtain at least two consecutive video frame images in the video image information; S22. Determine whether there is a moving object in the video image information according to the continuous video frame images. When there is a moving object in the video image information, the video image information is saved.
[0084] S3. ...
Embodiment 2
[0100] Please refer to figure 2 , the second embodiment of the present invention is:
[0101] A vehicle early warning terminal 100, corresponding to the method in Embodiment 1, including: a processor 1, a memory 2, and a computer program stored in the memory 2 and operable on the processor 1,
[0102] When the processor 1 executes the computer program, the following steps are implemented:
[0103] Obtain video image information within the preset range of the vehicle;
[0104] judging whether there is a moving object in the video image information;
[0105] If yes, calculate the size information, moving speed and moving direction of the moving object according to the video image information;
[0106] judging the danger level of the moving object according to the size information, moving speed and moving direction;
[0107] An alarm message is issued according to the danger level.
[0108] Further, when the processor 1 executes the computer program, the following steps are...

Abstract
The invention discloses a vehicle early warning method and a vehicle early warning terminal. The method comprises the following steps: acquiring video image information in a preset range of a vehicle;judging whether a moving object exists in the video image information or not; calculating size information, a movement speed, and a movement direction of the moving object according to the video image information if the moving object exists in the video image information; judging a danger level of the moving object according to the size information, the movement speed, and the movement direction;and sending alarm information according to the danger level. According to the vehicle early warning method and the vehicle early warning terminal, whether the moving object is in the vicinity of thevehicle or not is judged according to the video image information around the vehicle; and if the moving object is in the vicinity of the vehicle, judging the size, the movement speed, and the movementdirection of the moving object, determining the danger level of the moving object, and sending the alarm information according to the danger level; therefore, drivers can be effectively promoted to attract attention to prevent collision.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a vehicle early warning method and terminal. Background technique [0002] With the development of the automobile industry, driving recorders and monitoring radars are usually installed on vehicles for driving safety. The existing driving recorder has the following disadvantages: it can only detect whether the object is moving, but cannot judge the type of the moving object; it cannot judge the speed and direction of the moving object, and it cannot determine the warning level; situation (such as pedestrians breaking in suddenly) to give early warning; it is impossible to monitor and give early warning to the driver's blind spot of vision. Existing monitoring radars have the following disadvantages: they cannot record and save emergency videos; they cannot judge the type, speed and direction of moving objects, and cannot determine the level of early warning; they cannot implan...
