The invention discloses a detecting
system and a detecting method for fatigue driving of a driver, and belongs to the technical fields of
image processing and
pattern recognition. The
system comprises a human face localization module, a
human eye state judging module, a mouth state judging module and a fatigue determining module, wherein the human face localization module is connected with the
human eye state judging module and the mouth state judging module for communication; the determining result is sent to the fatigue determining module. The detecting method comprises the following steps: 1, localizing and detecting the human face; 2, judging the
human eye state; 3, judging the mouth state of the driver; 4, judging the
mental state of the driver. The detecting
system and the detecting method combine two obvious facial characteristics of the driver, namely the human eyes and the
human mouth, for complex judging; compared with recognition detection using a single method, the method provided by the invention has a higher recognition accuracy; through determining the
mental state of the driver, the driver under fatigue state is reminded to stop the vehicle for rest, so that traffic accidents are effectively reduced, and the safety of life and property is strongly guaranteed.
