Embodiment Construction

[0061] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0062] Specifically, the object of the present invention is to provide a fatigue driving detection method applied to multiple postures and judge whether the driver is in a fatigue state and whether it is in an abnormal driving state according to the feature points of the analysis of the face, so as to achieve To remind the driver in time to ensure driving safety.

[0063] In order to achieve the above object...

Abstract

The invention relates to a method for detecting fatigue driving and driving in an abnormal posture under multiple postures. The method comprises the following steps: step 1, image acquisition: acquiring driver image information; step 2, image recognition: carrying out real-time face detection on the acquired images; step 3, face feature point calibration: calibrating feature points of eyes and a mouth of the detected face; step 4, judgment of the states of the eyes and the mouth: for the feature points, analyzing the closing states of the eyes and the mouth by adopting an eye state detection method on the basis of face width information; step 5, detecting of three-dimensional posture of the head: detecting the three-dimensional posture of the head through geometrical characteristics; step 6, judging of the states of fatigue driving and driving in the abnormal posture: judging whether the driver is in fatigue or not according to the closing states of the eyes and the mouth, and judging whether the driver is in the abnormal driving state or not according to the three-dimensional posture of the head.

Description

technical field [0001] The invention relates to a method for detecting fatigue and abnormal driving postures under multi-stances, in particular, using a face feature point positioning method under multiple postures to simultaneously judge the state of human eyes and mouth, and adding three-dimensional posture detection of the head , so as to more accurately and effectively judge whether the driver belongs to fatigue driving and abnormal driving posture. Background technique [0002] Safe travel has become a very important issue in today's transportation field. With the development of the economy, the number of cars continues to increase, and at the same time, the number of traffic accidents is also increasing year by year. Among the many factors that affect safe travel Fatigue driving is one of the important hidden dangers of today's traffic safety. [0003] Driving is a heavy workload that consumes both physical and mental energy. The driver sits in an almost closed cab f...
