no. 1 example

[0037] see figure 1 , the figure shows a flow chart of a method for adjusting a rearview mirror according to an embodiment of the present invention, including:

[0038] S101. Acquire image information of the driver's face in the cab.

[0039] In this embodiment, by collecting the image in the cab and extracting the coordinates of the face in the image coordinate system, the coordinates in the image coordinate system are used to represent the position information of the face in the image.

[0040] S102. Obtain adjustment parameters of the rearview mirror according to the image information.

[0041] The above-mentioned rearview mirror may include any one or more of the following: a left rearview mirror, a right rearview mirror, and an interior rearview mirror.

[0042] In this embodiment, the coordinates of the center of the face can be obtained from the image information, and the adjustment parameters of the rearview mirror can be obtained by calculating the offset between th...

[0050] see figure 2 , the figure shows another flow chart of the rearview mirror adjustment method of the embodiment of the present invention, including:

[0051] S201. Collect images in the cab.

[0052] In this embodiment, images in the cab can be collected by an image sensor.

[0053] S202. Determine whether a face can be detected in the image according to the face recognition algorithm, if yes, proceed to step S203; otherwise, repeat this step.

[0054] This step is used for face recognition. The image is detected according to the face recognition algorithm. If a face is detected, the next step is performed. If no face is detected, this step is repeated.

[0055] S203. Extracting the position coordinates of the driver's face in the image coordinate system.

[0056] The above-mentioned image coordinate system (Pixel coordinate system) refers to the coordinate system used by the digital image inside the computer, and the image coordinate system is in pixel (Pixel).

[0078] Based on the same inventive concept, a rearview mirror adjustment device is also provided in the embodiment of the present invention. Figure 1 ~ Figure 2 The method in is similar, so the implementation of the device can refer to the implementation of the method, and the repetition will not be repeated.

[0079] see image 3 , the figure shows a schematic structural diagram of the rearview mirror adjustment device of this embodiment, and the rearview mirror adjustment device includes an acquisition module 301 , a calculation module 302 and an adjustment module 303 .

[0080] The acquisition module 301 is used to acquire the image information of the driver's face in the cab;

[0081] Calculation module 302 is used for obtaining the adjusting parameter of rearview mirror according to image information;

[0082] The adjustment module 303 is used to adjust the position of the rearview mirror according to the adjustment parameters. In this embodiment, the acquisition modu...

Abstract

The embodiment of the invention provides a rearview mirror regulating method and device and an automobile. The method includes the following steps that information of an image, located in a driving cab, of the face of a driver is obtained; according to the information of the image, a regulating parameter of a rearview mirror is obtained; according to the regulating parameter, the position of the rearview is regulated, full-automatic rearview mirror regulating can be achieved according to the position of the driver, manual operation is completely not needed, the position of the rearview mirror is self-adaptive to the position of the driver, the vision of the driver is ensured, and at the same time, the rearview mirror regulating method and device can also be compatible with other intelligent systems based on face recognition.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a method and device for adjusting a rearview mirror and an automobile. Background technique [0002] The angle adjustment of the car rearview mirror has an important influence on the safe driving of the car. Different drivers need to adjust the rearview mirror accordingly due to their different heights and sitting postures. [0003] The existing rearview mirror adjustment device requires the driver to manually adjust, and when the driver's sitting position is changed or the driver is replaced, the rearview mirror must be adjusted accordingly, which is troublesome to operate. Contents of the invention [0004] Embodiments of the present invention provide a rearview mirror adjustment method, device, and automobile, which solve the problem of manually adjusting the rearview mirror and can adaptively adjust the rearview mirror according to the position of the driv...
