Abstract
A signal triggering method and an in-vehicle electronic apparatus are provided. A plurality of images of a driver is continuously captured by using an image capturing unit, and a face motion information or an eyes open-shut information is obtained by detecting a face motion or an eyes open/shut action of the driver through the images. When the face motion information or the eyes open-shut information matches a threshold information, a specific signal is triggered and transmitted to a specific device.
Claims21
An in-vehicle electronic apparatus, comprising:
- an image capturing unit, capturing a plurality of images of a driver;
- and
- an operating device, coupled to the image capturing unit, receiving the images, and executing an image recognition procedure on each of the images to obtain a face motion information or an eyes open-shut information by detecting a face motion or an eyes open/shut action of the driver, and when the face motion information or the eyes open-shut information matches a threshold information, triggering a distress signal and transmitting the distress signal to a wireless communication unit.
A method for triggering a signal, for an in-vehicle electronic apparatus, the method comprising:
- continuously capturing a plurality of images, wherein each of the images comprises a face;
- detecting a nostril area of the face to obtain a nostrils position information;
- determining whether the face turns according to the nostrils position information to obtain a face motion information;
- comparing the face motion information with a threshold information;
- and
- when the face motion information matches the threshold information, triggering a specific signal.
A method for triggering a signal, for an in-vehicle electronic apparatus, the method comprising:
- continuously capturing a plurality of images, wherein each of the images comprises a face;
- detecting a nostril area on the face to obtain a nostrils position information;
- estimating an eye search frame according to the nostrils position information to detect an eye object in the eye search frame;
- determining whether the eye object is shut according to a size of the eye object, so as to obtain an eyes open-shut information;
- comparing the eyes open-shut information with a threshold information;
- and
- when the eyes open-shut information matches the threshold information, triggering a specific signal.
