摘要： A facial image recognition system for a driver of a vehicle includes an image capturing unit, an image processing unit, and a warning unit. The image capturing unit is used for capturing facial images of the driver. The image processing unit is electrically coupled to the image capturing unit, has installed therein a facial frame selecting and position correcting method and an identification comparison algorithm, and receives the facial images of the driver from the image capturing unit. The warning unit is electrically coupled to the image processing unit, and emits a warning signal when the image processing unit determines that an identification of the driver has changed.

摘要： A method and system for monitoring a driver is disclosed. Firstly, an inner cabin image of a vehicle's cabin is continuously captured. Next, a face detection of a driver for the inner cabin image is performed to obtain a face detection result. Next, the inner cabin image and the face detection result corresponding to the inner cabin image are stored. When the system observes that either the face of the driver is not detected or the face is not shown within a reasonable face region of at least two continuous inner cabin images according to each face detection result, the system outputs a warning signal to alert the driver. The invention determines a driving state of a driver in a cabin with a method of analyzing a position of a face or a head and using an image extractor having large capture range and a low resolution.
