摘要
The present invention recognizes a gaze derivative sign from a front image of a vehicle, synthesizes driving information (rate, wheel speed, steering angle, etc.) coming from a sensor of the vehicle, and warns that the vehicle is traveling off the driving lane due to inattention of a driver. In order to achieve this, the lane departure warning method through gaze derivative recognition according to the present invention includes: (a) photographing the front with a camera to obtain a front image; (b) recognizing a lane in the acquired front image; (c) recognizing the gaze derivative in the acquired front image; (d) comparing whether the recognition result of the lane and the recognition result of the gaze derivative are different; (e) When the recognition result of the lane and the recognition result of the gaze derivative are different, if the confidence level of the lane is less than a threshold value, the recognition result of the gaze derivative is used; otherwise, the recognition of the lane Using the results; (f) predicting a vehicle traveling direction by analyzing speed, steering angle, and yaw motion using the acquired front image; (g) determining normal driving or abnormal driving based on a result of recognizing the lane, a result of recognizing the gaze derivative, and a result of predicting the vehicle traveling direction; And (h) as a result of the determination, characterized in that it comprises a step of warning the departure of the lane when the abnormal driving.
