Abstract: Provided are a method and apparatus for determining driver's drowsiness. The method for determining driver's drowsiness includes: mapping the biometric data to a drowsiness determination model generated in advance; determining drowsiness of the driver based on a distribution of the biometric data in the drowsiness determination model; detecting first biometric data of the driver at a predetermined first time interval; correcting the biometric data of the driver detected during a time after the first time interval based on a center of distribution of the first biometric data; and determining whether or not the driver drowses based on the corrected biometric data, thereby optimizing the drowsiness determination model for each person/situation using driver data measured on a vehicle.
