Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The present invention comprises two cameras 105 installed on the interior rearview mirror 1 in the car, as figure 1 As shown, two cameras 105 are installed on both sides of the bottom of the interior rearview mirror, both facing the driver's head, to detect and extract the orientation and position of the driver's head and body. The luminous flux of the optical lens selected by the camera 105 (small optical image sensor) is F=6mm / F1.4, the focal length is 3mm, the resolution of the CMOS sensor is 1280×720 and an infrared supplementary light is installed, which can keep the image relatively clear under low light conditions The driver's head and eye information can be accurately captured.

[0030] The present invention comprises the rotation angle sensor 106 that is installed on the steering wheel, as Figure 4 As shown, it is used to measure the rotation angle o...

Abstract

The invention discloses an automatic adjustment system for automobile rearview mirrors. Two camcorder lenses are mounted on an inner rearview mirror, face to the head of a driver, and are used for detecting and extracting the orientation and the position of the head and the orientation and the position of the body of the driver; a corner sensor is mounted on a steering wheel and is used for detecting the rotating angle of the steering wheel so as to obtain the direction of automobile front wheels; a vehicle-mounted computer extracts out the orientation of the head of the driver, the three-dimensional space movement of the body of the driver, and the gazing direction of eyes of the driver through images shot by two independent optical image sensors, and through cradle heads, the directions of three rearview mirrors are adjusted so that the driver obtains the best view. According to the automatic adjustment system disclosed by the invention, the rearview mirrors can be automatically adjusted to provide the driver with the view of the most needed region, the disadvantages that a conventional rearview mirror system cannot be dynamically adjusted, view blind areas exist, and objective views are inconsistent with actual views are overcome, and the automatic adjustment system has enormous aids to the driving of the driver on roads.

Description

technical field [0001] The invention relates to an automatic adjustment system of a rearview mirror of an automobile, in particular to an automatic adjustment system of a rearview mirror of an automobile, which captures the features of the driver's line of sight during the driving of the automobile and provides the best visual field information. Background technique [0002] Rearview mirror is a necessary safety part in automobile driving safety. The angle of rearview mirror directly determines the area and size of the driver's field of vision. In the process of driving, since the angle of the rearview mirror cannot be adjusted at any time, there are a large number of blind spots of the driver's vision in various scenes such as changing lanes and reversing. Therefore, it is particularly important to develop an efficient and accurate automobile rearview mirror adjustment system. necessary. [0003] The traditional automatic adjustment method of car rearview mirror only measu...
