[0026] see figure 1 , figure 1 is a flow chart of an early warning prompt method provided by an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0027] Step 101, collect the image frame in front of the vehicle in real time.

[0028] In the embodiment of the present invention, the vehicle can be understood as a vehicle driven by the user himself. The above-mentioned front can be directly in front of the vehicle, or a little to the left of the front, or a little to the right of the front, and so on.

[0029] Step 102. Based on the image frame, it is judged whether there is a target vehicle in front of the own vehicle.

[0030] In the embodiment of the present invention, judging whether there is a target vehicle may be judged by extracting characteristic information of the vehicle. For example, it is identified by the degree of matching with a preset vehicle image, and when the degree of matching is greater than a preset threshold,...

[0039] see figure 2 , figure 2 It is a flow chart of another early warning prompt method provided by the embodiment of the present invention, such as figure 2 shown, including the following steps:

[0040] Step 201, collect the image frame in front of the vehicle in real time.

[0041] In the embodiment of the present invention, the vehicle can be understood as a vehicle driven by the user himself. The above-mentioned front can be directly in front of the vehicle, or a little to the left of the front, or a little to the right of the front, and so on.

[0042] Step 202, identifying the image frame, and judging whether the image frame contains lane lines.

[0043] In the embodiment of the present invention, the above-mentioned lane lines may be solid lines, or dashed lines, and may be two, three, or four, and so on.

[0044] Step 203: If the image frame includes the lane line, identify the target lane on which the vehicle is traveling, and set the target lane as a first t...

[0074] see image 3 , image 3 It is the early warning prompt device provided by the embodiment of the present invention, such as image 3 As shown, the early warning prompting device 300 includes a collection module 301, a first judgment module 302, a second judgment module 303 and an output module 304, wherein:

[0075] Acquisition module 301, is used for real-time acquisition image frame of this car ahead;

[0076] The first judging module 302 is used to judge whether there is a target vehicle in front of the vehicle based on the image frame;

[0077] The second judging module 303 is configured to judge whether the target vehicle has a braking signal if the first judging module 302 judges that the target vehicle exists in front of the vehicle;

[0078] The output module 304 is configured to output a corresponding warning prompt if the second judging module 303 judges that the target vehicle has a braking signal.

[0079] optional, such as Figure 4 As shown, the first ...

Abstract

The present invention provides an early warning prompting method and an early warning prompting device, which are applied to a vehicle system. The method may include: collecting an image picture in front of the vehicle in real time; judging whether there is a target vehicle in front of the vehicle based on the image picture; If the target vehicle exists, it is judged whether the target vehicle has a braking signal; if the target vehicle has a braking signal, a corresponding warning prompt is output. In this way, when the target vehicle in front of the vehicle sends out a braking signal, a corresponding early warning prompt can be output, and the user can take corresponding countermeasures to prevent rear-end collision accidents.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an early warning prompting method and an early warning prompting device. Background technique [0002] With the development of automobile technology and the continuous improvement of people's living standards, automobiles have become a common means of transportation and have brought great convenience to users' travel. When the car is driving, it is necessary to pay attention to the driving conditions of the vehicle in front at all times. When the front vehicle brakes, the rear vehicle needs to take corresponding avoidance measures in time to prevent rear-end collisions. The driver of the vehicle behind mainly judges whether the vehicle in front is braking by observing the brake lights of the vehicle in front. If the driver is negligent, it will easily lead to the occurrence of a rear-end collision accident. [0003] It can be seen that in the prior art, there is a problem that the dr...
