Toyota faces the future of active safety Data mapping of the face helps technology to better understand the driver

摘要

Toyota's European R&D centre is developing 3D facial tracking techniques to estimate the driver's emotional state. The data could be used to make active safety features such as pre-crash systems more effective by pre-empting hazardous driving conditions. Human error causes most road accidents. Toyota was the first to introduce camera-based driver monitoring to detect drowsiness but this technology goes further and uses a 3D model to determine if the driver is in an angry, happy or neutral mood, An angry driver approaching a busy intersection, for example, will probably take more risks.
