| titleOfInvention | A driver fatigue detection method and detection device based on steering wheel image |
| abstract | The present invention is a driver fatigue detection method and detection device based on a steering wheel image. The main steps of the method are: obtaining a template image, obtaining the coordinates of the center position of the steering wheel, obtaining feature points on the steering wheel, and obtaining feature points in the current frame and the next frame Coordinate position, calculate and store the steering wheel rotation angle; to calculate the zero speed percentage and angle standard deviation of the steering wheel within a certain period of time; use the support vector machine classification algorithm to train the sample set, and find out the decision function for judging whether the driver is in a state of fatigue. During monitoring, the steering wheel image is collected in real time, and the current zero-speed percentage and the value of the angle gauge deviation are obtained from the steering wheel angle, which is substituted into the decision function. The result is 1, which means that the current driver is in a fatigue state, and an alarm is given immediately. The camera of the device is installed on the top of the cab, and the camera is connected to the central processor; the central processor is also connected to the alarm module. The invention has simple operation, accurate measurement results, can calculate the steering wheel rotation angle larger than one cycle, and has a wider application range. |
