Driver monitoring systems, like those used by Seeing Machines and Guardian, use driver-facing and front-facing cameras that produce black-and-white videos for specific technical reasons. These systems also include infrared cameras that capture heat signatures and temperature variations on the driver’s face and surroundings. Infrared technology enhances visibility in various lighting conditions, including darkness or low light, which is essential for reliable driver monitoring day and night. Since the human eye cannot perceive infrared wavelengths, the resulting images appear in black and white, representing these heat patterns. This monochromatic display simplifies facial feature analysis, eye movements, and head orientation, allowing the system’s algorithms to accurately identify driver fatigue and distraction, enhancing road safety.
