Problems solved by technology

A reasonable rearview mirror angle is an important prerequisite for safe driving. Manual adjustment is cumbersome and due to differences in driver levels, it is difficult to ensure that the rearview mirror is at the optimal angle position for man-machine
In addition, due to the rapid popularity of shared mobility, the driver of a single car may change frequently
[0003] There are two ways to adjust the rearview mirror in the prior art: one is manual mechanical adjustment of the rearview mirror. After the driver’s sitting posture is adjusted, the left and right rearview mirrors need to be adjusted with mechanical switches. The adjustment efficiency and accuracy are very low. It is inconvenient to use; the other is to adjust the rearview mirror electrically. When there is an adjustment requirement, the driver can adjust the rearview mirror on the left and right sides through the electric switch. This adjustment method is more convenient than manual mechanical adjustment, but the driver At least four adjustments are required to complete the adjustment, which are the adjustment of the up and down angle of the left rearview mirror, the adjustment of the left and right angle of the left rearview mirror, the adjustment of the up and down angle of the right rearview mirror, and the adjustment of the left and right angle of the right rearview mirror. Adjustment, adjustment efficiency is low

Embodiment 1

[0034] This embodiment provides a method for adjusting a car rearview mirror, such as figure 1 As shown, the adjusting method of the automobile rearview mirror comprises the following steps:

[0035] S11. Detecting that the driver is seated;

[0036] S12, collecting the face image information of the driver, and judging whether the driver is a new user;

[0037] S13. If the driver is a new user, remind the driver to adjust the sitting posture;

[0038] S14. Collect the driver's eye point position and store the eye point position, wherein the eye point position is the midpoint position of the connecting line between the pupils of the driver's eyes;

[0039] S15, transforming the position of the eye point into absolute coordinates under the absolute coordinate system of the vehicle;

[0040] S16. Calculate the adjustment angle of the rearview mirror according to the absolute coordinates;

[0041] S17. Store the adjustment angle, and adjust the rearview mirror to the adjustmen...

Embodiment 2

[0054] This embodiment provides a method for adjusting a car rearview mirror, such as figure 2 As shown, the adjusting method of the automobile rearview mirror comprises the following steps:

[0055] S21, detecting that the driver is seated;

[0056] S22, collecting the face image information of the driver, and judging whether the driver is a new user;

[0057] S23. If the driver is an old user, after the driver adjusts the sitting posture, collect the position of the first eye point of the driver;

[0058] S24. If the difference between the driver's eye point position and the previous eye point position is greater than the first preset distance, convert the first eye point position into absolute coordinates in the vehicle's absolute coordinate system;

[0059] S25. Calculate the adjustment angle of the rearview mirror according to the absolute coordinates;

[0060] S26. Store the adjustment angle, and adjust the rearview mirror to the adjustment angle at the same time;

...

Embodiment 3

[0064] This embodiment provides a method for adjusting a car rearview mirror, such as image 3 As shown, the adjusting method of the automobile rearview mirror comprises the following steps:

[0065] S31. Detecting that the driver is seated;

[0066] S32, collecting the face image information of the driver, and judging whether the driver is a new user;

[0067] S33. If the driver is an old user, after the driver adjusts the sitting posture, collect the first eye point position of the driver. If the distance is set, adjust the rearview mirror to the adjustment angle corresponding to the driver;

[0068] S34. During driving, collect the driver's third eye point position, if the distance between the first eye point position and the third eye point position is greater than the first preset distance and the duration exceeds the second preset time length;

[0069] S35. Converting the position of the third eye point into absolute coordinates in the absolute coordinate system of th...

Abstract

The invention relates to the technical field of rearview mirror adjustment, and discloses an automobile rearview mirror adjusting method and a rearview mirror adjusting device. The automobile rearviewmirror adjusting method comprises the steps that S11, detecting sitting of a driver; s12, collecting face image information of the driver; s13, if the driver is a new user, reminding the driver to adjust the sitting posture; s14, collecting the eye point position of the driver and storing the eye point position; s15, converting the received eye point position into an absolute coordinate; s16, calculating the adjusting angle of the rearview mirror; and S17, adjusting the rearview mirror to the adjusting angle. According to the adjusting method of the automobile rearview mirror, the angle of the rearview mirror can be automatically adjusted according to different drivers, the adjusting efficiency and the adjusting precision can be greatly improved, and the adjusting convenience is improved.

Description

technical field [0001] The invention relates to the technical field of adjusting rearview mirrors, in particular to an adjusting method for an automobile rearview mirror and an adjusting device for the rearview mirror. Background technique [0002] At present, with the improvement of the electrification of automobiles, the functions of automobiles tend to be intelligent and scene-based, so more consideration needs to be given to user scenarios and user experience. A reasonable rearview mirror angle is an important prerequisite for safe driving. Manual adjustment operations are cumbersome and due to differences in driver levels, it is difficult to ensure that the rearview mirror is at the optimal angle position for man-machine. In addition, due to the rapid popularity of shared mobility, the driver of a single car may change frequently. [0003] There are two ways to adjust the rearview mirror in the prior art: one is manual mechanical adjustment of the rearview mirror. Afte...
