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.
