Embodiment Construction

[0050] figure 1 It is a schematic diagram of the vehicle safety system 1 according to the first embodiment of the present invention, which can be used to control or activate the vehicle device corresponding to the pupil position according to the pupil position of the eyeball 9 . The vehicle safety system 1 includes a sensing unit 10 , a processing unit 12 , a control unit 14 , at least one vehicle device 16 and a display device 18 .

[0051] The sensing unit 10 is configured to acquire an image frame IF including an eyeball image of the eyeball 9 at a preset distance. The sensing unit 10 can be, for example, a charge coupled device image sensor, a complementary metal-oxide semiconductor image sensor or other sensors capable of sensing light energy.

[0052] Generally speaking, when the eyeball 9 looks down, the upper eyelid will cover a part of the eyeball 9. Therefore, in some embodiments, if the sensing unit 10 is arranged on the glasses 2 facing the eyeball 9 side, such a...

Abstract

The invention provides an automotive safety system, which comprises a sensing unit, a processing unit, a control unit and a display unit, wherein the sensing unit is used for acquiring an image frame of an eyeball image containing an eyeball at a preset distance; the processing unit is used for calculating the pupil position of the eyeball image in the image frame and generating a driving signal corresponding to the pupil position; the control unit is used for triggering an automotive device associated with the pupil position according to the driving signal; and the display unit is used for displaying information of the automotive device.

Description

technical field [0001] The present invention relates to a vehicle safety system, in particular to a vehicle safety system using pupil detection technology and an operation method thereof. Background technique [0002] Cars generally have two side mirrors and an interior mirror, which are respectively arranged in fixed positions outside and inside the car. For example, when the driver wants to watch the situation at the right rear of the car, he needs to observe the situation at the right rear of the car through the rearview mirror on the right side, and when the driver turns his head to watch the rearview mirror, his line of sight will temporarily leave the car ahead and increases the risk of a driving accident. In order to improve driving safety, various vehicle safety systems have been proposed in the industry to compensate for the deficiency of the rearview mirror. [0003] In known safety systems for vehicles, for example, a car usually has a plurality of reversing sen...
