Embodiment 1
[0045] The adjusting method of the rearview mirror system based on the real-time posture automatic adjustment of the present invention has the following steps:
[0046] 1) Obtain the position information of the user's eyes by using a camera device with the function of obtaining the three-dimensional space coordinates of the human eye position, and determine the coordinates (ex, ey, ez) of the eyes relative to the origin of the space in the vehicle;
[0047] 2) Determine the angle γ between the highest point of the window and the vertical midpoint of the main body of the rearview mirror, and the horizontal line;
[0048] 3) According to the spatial coordinates of the eyes in the car, the line connecting the eyes and the vertical midpoint of the main body of the rearview mirror can be calculated, and the included angle with the normal line of the main body of the rearview mirror is β;
[0049] 4) According to the principle of reflection, the angle between the reflected line of s...

[0055] The present invention also provides a method for adjusting the rearview mirror system automatically based on real-time attitude, which has the following steps:
[0056] 1) Obtain the position information of the user's eyes by using a camera device with the function of obtaining the three-dimensional space coordinates of the human eye position, and determine the coordinates (ex, ey, ez) of the eyes relative to the origin of the space in the vehicle;
[0057] 2) Determine the angle γ between the highest point of the window and the vertical midpoint of the main body of the rearview mirror, and the horizontal line;
[0058] 3) According to the spatial coordinates of the eyes in the car, the line connecting the eyes and the vertical midpoint of the main body of the rearview mirror can be calculated, and the included angle with the normal line of the main body of the rearview mirror is β;
[0059] 4) According to the principle of reflection, the angle between the reflected li...

Abstract
The invention provides a system automatically adjusting a rear view mirror based on real-time gestures. The system automatically adjusting the rear view mirror based on the real-time gestures includesa camera head for measuring three-dimensional space coordinates of human eye positions, a rear view mirror device and a control unit, wherein the camera head is located in the front of driving seats,the rear view mirror device is driven by a motor, and the control unit is electrically connected with the motor and the camera head. The invention further provides a regulating method of the rear view mirror, the method includes the steps that first, three-dimensional space coordinates of eyes are determined, and then according to the size of a rear vehicle window and the relative position of therear vehicle window and the rear view mirror inside a vehicle to determine the specific adjusting angle range of the rear view mirror, automatic adjusting of the rear view mirror inside the vehicle is realized. According to the system automatically adjusting the rear view mirror based on the real-time gestures and the regulating method of the rear view mirror, the technical problem that in general, the rear view mirror inside the vehicle needs to be adjusted manually is solved, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of automobile rearview mirrors, in particular to a system for automatically adjusting rearview mirrors based on real-time posture and an adjustment method thereof. Background technique [0002] The interior rearview mirror is an indispensable part of the car during driving. In the process of driving, driving for a long time will cause the driver's posture to change. At this time, it is necessary to adjust the rearview mirror to ensure the driving vision. In addition, every time the driver is changed, the seat and the interior rearview mirror need to be readjusted. Sometimes it is easy to forget the adjustment of the interior rearview mirror, resulting in the rearview mirror being adjusted only when the car is driving. However, when the vehicle is running, the driver will lose control of the steering wheel with one hand while adjusting the ordinary rearview mirror, and at the same time, his sight and attenti...
