Problems solved by technology

However, due to the high price of the night vision system, it is generally only sold as an option for luxury cars
Most of the rear-mounted car night vision devices on the market are an infrared camera and a display screen. They have no other functions except the night vision function, which has low practicability and affects the appearance.
[0003] In the process of realizing the present invention, the inventor found that the prior art has the following defects: the original car does not have a night vision system, and the night vision system installed after the car is expensive and has a single function

Embodiment 1

[0024] figure 1 It is a flow chart of the collision warning method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the intelligent rearview mirror performs collision warning under the condition of driving at night. This method can be executed by a collision warning system, which can Realized by means of software and / or hardware, and generally can be integrated in the vehicle rearview mirror, the method of the present embodiment specifically includes the following steps:

[0025] S110. When the smart rearview mirror determines that the vehicle satisfies the night driving condition, it acquires a real-time image in front of the vehicle through the first infrared camera.

[0026] Wherein, the nighttime driving condition may be determined according to the system time, for example, after 8:00 pm and before 5:00 am. When the user is in a different country or region, the user can choose or automatically switch to the correspond...

Embodiment 2

[0034] figure 2 It is a flow chart of a collision warning method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, the step of obtaining the distance between the obstacle and the vehicle by the intelligent rearview mirror is further optimized as follows: the intelligent rearview mirror controls the opening of the an advanced driving assistance system in the vehicle, and obtain the distance between the obstacle and the vehicle through the advanced driving assistance system. At the same time, after the smart rearview mirror in the step performs a collision warning according to the obtained distance and the real-time vehicle speed of the vehicle, it also includes: the smart rearview mirror sends an early warning prompt signal to the associated smart wearable device to The smart wearable device is configured to provide a collision warning prompt to the wearing user in the form of s...

Embodiment 3

[0049] image 3 It is a flowchart of a collision warning method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, the step of obtaining the distance between the obstacle and the vehicle by the smart rearview mirror is further optimized as follows: the smart rearview mirror turns on the second Camera, wherein, the second camera and the first infrared camera jointly constitute a binocular camera; the smart rearview mirror acquires a depth-of-field image in front of the vehicle captured by the binocular camera; the smart rearview The mirror acquires the distance between the obstacle and the vehicle according to the depth information corresponding to the obstacle in the depth image. At the same time, after the smart rearview mirror in the step performs a collision warning according to the obtained distance and the real-time vehicle speed of the vehicle, it also includes: the smart r...

Abstract

An embodiment of the invention discloses a collision early warning method and system, a vehicle-mounted rearview mirror and a storage medium. The method comprises the following steps: when an intelligent rearview mirror determines that a vehicle meets a night driving condition, acquiring a real-time image in front of the vehicle by a first infrared camera; if the intelligent rearview mirror recognizes a barrier in front of the vehicle from the real-time image, acquiring the distance from the barrier to the vehicle; and carrying out collision early warning by the intelligent rearview mirror according to the acquired distance and the real-time speed of the vehicle. According to the embodiment of the invention, it determines that the vehicle runs at night through the intelligent rearview mirror, the real-time image in front of the vehicle is acquired to recognize the barrier in front of the vehicle, collision early warning is carried out according to the distance between the barrier and the vehicle and the real-time speed of the vehicle, thus, a driver can judge potential collision danger when drives the vehicle at night, then the system can give an alarm for the driver, and the safety of night driving is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of intelligent rearview mirror night vision technology, and in particular to a collision warning method and system, a vehicle rearview mirror and a storage medium. Background technique [0002] The night vision system can display potential dangerous situations beyond the range of the headlights on the windshield at night, thereby broadening the driver's field of vision and avoiding traffic accidents. The night vision system can also help drivers meet glare at night See what's ahead. However, due to the high price of night vision systems, they are generally only sold as options for luxury cars. Most of the rear-mounted car night vision devices on the market are an infrared camera and a display screen, which have no other functions except the night vision function, which has low practicability and affects the appearance. [0003] In the process of realizing the present invention, the inventor fou...
