Problems solved by technology

For example: the function of the above scheme is single, and the judgment of the eye image can only be used to identify the situation of drowsiness, and the situation of the driver's inattention and turning his head for a long time cannot be recognized; Recognition; In addition, this scheme only recognizes the state of the driver's eyes open. When the driver encounters strong frontal light and squints his eyes, there is a possibility of false alarms, so the reliability is not high

Embodiment Construction

[0048]The following embodiments describe the technical solution of the present invention in further detail in conjunction with the accompanying drawings:

[0049] see Figure 1a , the central points of the two eyes 21, 22 and the mouth 23 of the frontal human face 1 form an isosceles triangle (hereinafter referred to as: human face triangle 2) with the lower apex. The connecting line is perpendicular to the bottom edge.

[0050] Assuming that the image acquisition device is placed at a fixed position in front of the face, no matter how far or short it is from face 1, the center point of the two eye and mouth images in the face image collected by the image acquisition device constitutes For a triangle (hereinafter referred to as: image triangle), the proportions of the corresponding sides are the same. That is: the above-mentioned relationship between the face triangle and the image triangle is a similar triangle.

[0051] see Figure 1a , 1b , assuming that the absolute len...

Abstract

The invention discloses a motor vehicle safety control method and a motor vehicle safety control system. The method comprises the following steps of: acquiring a face image of a driver according to a predetermined time interval when a motor vehicle is in a start state; identifying two eyes and a mouth in the face image, and positioning the central coordinates of the two eyes and the mouth; forming an image triangle based on the central coordinates; and comparing each edge of the image triangle with the corresponding edge of a pre-stored face triangle, judging whether the driver is in a fatigue or drunk driving state, or judging whether the attention of the driver is concentrated, giving a sound or light alarm based on the judgment result, and even directly controlling the operation of a motor vehicle safety system to prevent traffic accidents.

Description

technical field [0001] The invention relates to motor vehicle control technology, in particular to a method and system for judging whether there is a potential safety hazard in driving based on the recognition result of the driver's face image, reminding the driver to keep driving safely, and even further automatically controlling the driving of the motor vehicle, which belongs to automatic control technology field. Background technique [0002] The driving safety of motor vehicles has always been one of the focuses of the society. The main cause of safety accidents in motor vehicles, except that the motor vehicle itself breaks down, the driver's operation error is the most important factor. In particular, after long-term technological development, the mechanical and electrical quality of motor vehicles and road safety facilities have been increasingly improved; therefore, the rate of motor vehicle safety accidents caused by non-human factors is getting lower and lower, and...
