The fatigue level of military pilot directly affects the flight safety. The fatigue level of system operator directly affects the operational electiveness. Developing high-performance personnel fatigue real-time monitoring and alerting technology on board is significant. Based on eye states detection, we judge the fatigue state of military pilot. Though the location speed of maximumvariancebetweentwoclasses is faster and the location speed of gray-levelintegrationprojection is faster, it is difficult to directly find the feature points. To solve this problem, we introduce the way of eye location and detection. It is based on Gabor transforms projected subspace and multi-state template. The horizontal direction gray scale of the eye changes frequently, sharply. Compared with the eyebrow and nose, the change of eye gray scale is more frequently. After eye location, we take PERCLOS as the method to judge the state of the military pilot and we statistic the percentage of the number of eyes closed picture, f. If f is larger than 0.4, we think the military pilot is fatigue. If f is larger than 0.1 but less than 0.4, we think the military pilot is out of mind. If f is less than 0.1, we think the military pilot is full of energy.
