Abstract
There is provided a vehicle safety system including a sensing unit, a processing unit, a control unit and a display unit. The sensing unit is configured to capture an image frame containing an eyeball image from a predetermined distance. The processing unit is configured to calculate a pupil position of the eyeball image in the image frame and generate a drive signal corresponding to the pupil position. The control unit is configured to trigger a vehicle device associated with the pupil position according to the drive signal. The display unit is configured to show information of the vehicle device.
Claims20
A vehicle safety system, comprising:
- a sensing unit configured to capture an image frame containing an eyeball image of an eyeball from a predetermined distance;
- a processing unit configured to
- calculate an eyeball position in the image frame, and
- generate a drive signal corresponding to one of at least two sub-regions in the image frame in which the eyeball position locates;
- and
- a control unit configured to trigger a vehicle device associated with the one of the at least two sub-regions in which the eyeball position locates according to the drive signal.
An operating method of a vehicle safety system, the operating method comprising:
- capturing an image frame containing an eyeball image of an eyeball;
- calculating, by a processing unit, an eyeball position of the eyeball image in the image frame;
- generating a drive signal corresponding to one of at least two sub-regions in the image frame in which the eyeball position locates;
- and
- triggering a vehicle device associated with the one of the at least two sub-regions in which the eyeball position locates according to the drive signal.
