During driving, the continuous inspection of the driver’s face for various alertness signs can produce life-saving alerts. The driver-inspection camera can analyze, and create immediate alarms for conditions of stress, fever, fatigue, sleepiness.
Since environmental lighting conditions in cabin change between different cars and time of day, a NIR inspection is much more robust and predictable than RGB inspection. Moreover, multiple wavelength continuous image capturing is essential for accurate results compared to solution based on a single wavelength.
