Abstract
An image analyzer for analyzing the position of a vehicle driver in a three-dimensional coordinate system. The analyzer comprises a light emitting element for emitting an infrared light the driver's face portion and an image detector arranged to receive reflected infrared light to generate an optical image of the driver's face portion. A microcomputer includes a memory for storing an electronic image corresponding to the optical image and processes the stored image to determine the position of a facial feature, such as an eye, in a three-dimensional coordinate system. Position indicating data is utilized in a driver assistance system.
Claims14
A position analyzer for a vehicle driver, comprising:
- light emitting means for directing light to said driver's face;
- light detecting means comprising a pair of two-dimensional image sensors for detecting light reflected from said driver's face;
- and
- recognition means for determining the position of said driver in a three-dimensional coordinate system in response to optical images detected by said image sensors.
