A driver fatigue state detection method provided by the present invention uses the SIFT feature of the eyes to enter the classification model for calculation to obtain confidence, and judges the state of eyes open and closed according to the confidence level, which can not be affected by the angle of the face, and has the ability to rotate Invariance, the accuracy of human eye measurement is high, and the calculation process is simple, and the driver's driving fatigue state can be detected in time, which can meet the requirements of real-time detection. In addition, the present invention also provides a driver's fatigue state Detection Systems.
Description
technical field [0001] The invention relates to the field of safe driving, in particular to a driver fatigue state detection method and system. Background technique [0002] With the rapid development of the transportation industry, driver fatigue driving has become one of the main reasons for frequent traffic accidents, and drivers often cannot realize that they are in a state of fatigue driving due to the working environment and driving time, which leads to major accidents. The automatic detection of driver fatigue status is an important means to prevent traffic accidents. A large number of experimental data prove that the percentage of eye closure time per unit time has a good correlation with the fatigue degree. Therefore, it is very important to detect the driver's eye status. significance. [0003] In recent years, with the rapid development of image processing and pattern recognition technology, it has become a feasible solution to judge the driver's fatigue status b...
