With the rapid development of aerospace technique, the performance of advanced fighter aircraft becomes improved. These aircrafts can perform beyond the acceleration tolerance limits of human. G-induced loss of consciousness (G-LOC) has become Air-Force's a serious human factor problem. It remains a killer of both men and machines. Various G-LOC research efforts all over the world about the principle and monitoring system have been initiated. Nowadays, in order to detect G-LOC, under a special centrifuge training facility environment, we studied the methods of testing subject's eye blink, head-slump and grip strength measuring force stick and control ability. This article only presents the method for real-time detection of head-attitude, recording head video image any analysis of moving track by video image. We have developed image processing, which is more advanced than infrared technique and laser technique for more information. This method is simple and avoids the affect of infrared ray to partial physiological sensors.
