Problems solved by technology

[0003] Existing anti-lock brakes (ABS), brake force distribution (EBD / CBC), brake assist (EBA / BAS / BA), traction control (ASR / TCS / TRC), vehicle stability control (ESP / DSC / VSC), Technologies such as vehicle-mounted anti-collision radar and fatigue driving detection and early warning can guarantee the safety of the driver to a certain extent, but the above-mentioned technologies can only prevent uncontrollable dangers of the vehicle, and rarely pay attention to the driver's line of sight. The driver's dangerous driving behavior cannot be warned in time

Embodiment 1

[0038] Please refer to figure 1 , is a safe driving early warning system of the present application, which includes a camera 1, a digital signal processor 2, a vehicle-mounted direction sensor 6 and a vehicle-mounted alarm device 3, which will be described in detail below.

[0039] Camera 1 is used to collect the driver's iris image data or face image data and send it to the digital signal processor, and is used to receive and automatically adjust the focus according to the focal length parameter fed back by the digital signal processor and to capture the driver's eyeball reflection image data in real time ;

[0040] Such as figure 2 A schematic diagram of the eye reflection image is shown.

[0041] The digital signal processor 2 is used to obtain the iris image or face image, extract the driver's eye size information from the iris image or face image data, and calculate the corresponding eyeball reflection captured by the camera according to the driver's eye size The imag...

example 1

[0057] Example 1: During high-speed driving, the driver’s line of sight should be fixed on the front of the car. If it is detected from the eyeball reflection image that the current driver’s line of sight is not directly in front for longer than the preset time, the digital signal processor 2 will send a corresponding signal. alarm signal.

example 2

[0058] Example 2: When the vehicle turns the steering wheel while driving, the driver's line of sight should rotate with the rotation of the steering wheel. If it is detected from the eye reflection image that the current driver's line of sight is different from the steering wheel rotation angle by a preset angle, the duration exceeds the preset time. time, the digital signal processor 2 will send a corresponding alarm signal.

Abstract

A safe driving warning method and system, the system includes a camera and a digital signal processor, because the system collects the driver's iris image data or face image data and extracts the driver's eye size information therefrom, and according to the driver's The size of the eye is calculated so that the eyeball reflection image captured by the camera has a high-definition focal length parameter, and then the camera is controlled to automatically adjust the focal length according to the focal length parameter to shoot a high-definition eyeball reflection image, ensuring that the safety warning system can be based on Eye reflection images make accurate judgments and decisions, avoiding dangerous driving and ensuring safe driving. Correspondingly, the present application also provides a car including the safe driving warning system and a readable storage medium.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a safe driving early warning method and system, a vehicle and a readable storage medium. Background technique [0002] With the progress of the economy and society, the rapid development of the automobile industry, the increasing number of automobiles, the increasingly busy traffic, and the increase in automobile accidents resulting in casualties and property losses have become a social problem that cannot be ignored. Safe driving is very important to human beings. Safety is self-evident, and the issue of safe driving needs urgent attention. [0003] Existing anti-lock brakes (ABS), brake force distribution (EBD / CBC), brake assist (EBA / BAS / BA), traction control (ASR / TCS / TRC), vehicle stability control (ESP / DSC / VSC), Technologies such as vehicle-mounted anti-collision radar and fatigue driving detection and early warning can guarantee the safety of the driver to a certain ...
