Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and in particular to a sun visor vanity mirror adjustment control method and device. Background Art

[0002] Car makeup mirrors are generally placed on the back of the sun visor. Due to the fixed point of the sun visor itself, there will be a certain angle between the sun visor and the face when it is opened, resulting in the image of the face in the makeup mirror being offset or only part of the face being visible. Passengers are required to tilt their heads to adapt to the position of the makeup mirror, and the fixed position of the makeup mirror cannot take into account different riding positions.

[0003] In addition, some models have a large front windshield angle and the sun visor is arranged relatively close to the front of the car, which will cause the makeup mirror to be far away from the person. Moreover, since the size of the makeup mirror itself is limited by environmental factors and cannot be increased, passengers will be required to lean forward to adapt to the position of the makeup mirror, which sometimes affects the driver's observation of the exterior rearview mirror.

[0047] This embodiment provides a sun visor makeup mirror adjustment control method, combined with Figure 1 As shown in the flowchart, the sun visor makeup mirror adjustment control method includes steps 101 to 104:

[0048] Step 101: Acquire facial image data of a passenger captured by a three-dimensional camera;

[0049] In this embodiment, the sun visor makeup mirror adjustment control method can be executed by a body controller. The body controller is a controller or control unit installed in the vehicle body, which is used to control vehicle accessories, such as makeup mirrors. A three-dimensional camera is installed inside the vehicle near the windshield. The three-dimensional camera is used to capture the face of the passenger to obtain facial image data. It should be noted that the facial image data is image data with depth information, and each data point in the facial image data has three-dimensional coordinate information. The facial image data captured by the three-dimensional camera is data with the position of the three-dimensional camera as the origin of the coordinate system.

[0050] Step 102: Determine the left and right eye points and nose point of the passenger based on the facial image data;

[0051] According to the facial image data, the position information of the passenger's left eye point, right eye point and nose point can be analyzed. The analysis method belongs to the prior art. For example, a recognition model is established, and the recognition model is trained by the labeled human image sample data to obtain the trained recognition model. Then, the facial image data obtained by shooting is input as input data to the recognition model, so as to obtain the passenger's left eye point, right eye point and nose point.

[0052] Step 103: performing a first adjustment on the initial position of the vanity mirror according to the left and right eye points and nose point of the passenger;

[0053] In this embodiment, when a passenger wants to use the vanity mirror, the sun visor can be opened, and the vanity mirror is set on the back of the sun visor. The opened vanity mirror is in the initial position. The vanity mirror can be opened automatically or manually. When setting the initial position, the initial position set is slightly different for different car models. The initial position of the vanity mirror has been pre-calibrated in the three-dimensional camera coordinate system.

[0054] It should be noted that the space in the car is limited, and different passengers and sitting postures make the angle and distance between the passenger's face and the makeup mirror in the initial position slightly different, resulting in slight deviations in the imaging of different passengers' faces in the makeup mirror. Specifically, the distance between the face and the makeup mirror is different, the face is tilted to the left or right relative to the makeup mirror, the face is tilted up or down relative to the makeup mirror, and the makeup mirror is not parallel to the face. But in general, most passengers' faces are imaged in the makeup mirror in the initial position, but the imaging effect may not be ideal, and passengers often need to fine-tune the makeup mirror in the initial position.

[0055] Combination Figure 2 As shown, the adjustment can be divided into two parts, namely the first adjustment and the second adjustment. The first adjustment includes rotation around the axis adjustment and translation adjustment. The specific steps may include:

[0056] According to the left and right eye points of the passenger, determine the center point of the left and right eye points and the connecting line of the left and right eye points;

[0057] According to the line connecting the left and right eye points and the nose point, rotate the makeup mirror around the horizontal axis and the vertical axis respectively;

[0058] The makeup mirror is translated according to the preset viewing distance and the center points of the left and right eye points.

[0059] After determining the left eye point and the right eye point of the passenger, the left eye point can be connected with the eye point to obtain the left and right eye point connection line, and a point in the middle of the left and right eye point connection line is taken as the center point of the left and right eye points. Then, according to the left and right eye point connection line and the nose point, the makeup mirror is rotated around the axis to make the plane of the makeup mirror as parallel to the face as possible. Then, the makeup mirror is translated forward and backward and left and right to make the distance between the face and the makeup mirror at an appropriate distance and moderate left and right.

[0060] Specifically, the steps of rotating the makeup mirror around an axis may include:

[0061] Rotate the vanity mirror about the longitudinal axis until the vanity mirror is parallel to the line connecting the left and right eye points of the passenger;

[0062] The makeup mirror is rotated around the horizontal axis so that the difference between the vertical distance from the nose point to the makeup mirror plane and the vertical distance from the left eye point to the makeup mirror plane is within a preset difference range, or the difference between the vertical distance from the nose point to the makeup mirror plane and the vertical distance from the right eye point to the makeup mirror plane is within a preset difference range.

[0063] It should be noted that after the makeup mirror is rotated around the longitudinal axis, the plane of the makeup mirror is parallel to the line connecting the left and right eye points of the passenger, but the passenger's face requires at least three points: the left eye point, the right eye point and the nose point to be determined. Therefore, the makeup mirror needs to be rotated around the horizontal axis. According to statistics, for most people, the height of the nose tip is generally 22-24mm. Therefore, this embodiment can first determine the first vertical distance from the nose point to the makeup mirror plane, and the second vertical distance from the left eye point or the right eye point to the makeup mirror plane, and then calculate the difference between the first distance and the second distance. If the difference is within the preset difference range, it means that after the rotation operation, the makeup mirror plane is basically parallel to the face. Among them, when setting the preset difference range, the statistical pen tip height can be referred to. For example, the preset difference range can be 20-26mm.

[0064] In an optional implementation, the step of translating the cosmetic mirror may include:

[0065] According to the preset viewing distance, adjust the vertical distance from the center point of the left and right eye points to the makeup mirror;

[0066] Move the makeup mirror along the horizontal axis so that the projection points of the center points of the left and right eye points on the makeup mirror are on the vertical axis of the makeup mirror.

[0067] The translation in this step mainly includes front-to-back translation and left-to-right translation. The viewing distance is a preset value, which is determined based on the collected usage habits of passengers. Calculate the vertical distance from the center point of the left and right eye points to the makeup mirror, and then adjust the vertical distance according to the viewing distance, that is, adjust the distance from the face to the makeup mirror. After that, the makeup mirror needs to be adjusted left and right according to the situation. When adjusting, the projection point of the center point on the makeup mirror needs to be on the longitudinal axis of the makeup mirror. It should be noted that the settings of the longitudinal and transverse axes of the makeup mirror can be combined Figure 2 As shown, the intersection of the longitudinal axis and the transverse axis can be used as the center point of the makeup mirror.

[0068] Step 104: Perform a second adjustment on the adjusted initial position of the makeup mirror according to the nose point to determine the target position of the makeup mirror.

[0069] In this embodiment, the second adjustment refers to adjusting the makeup mirror to the center up and down so that the face image is displayed in the center of the makeup mirror. Considering that the nose point is basically at the center point of the face plane, the position of the nose point can be referred to when adjusting the center up and down. Specifically, the second adjustment steps may include:

[0070] Move the makeup mirror along the longitudinal axis so that the nose point on the makeup mirror is on the transverse axis of the makeup mirror.

[0071] That is to say, the nose point is taken as the center point of the face plane, and the makeup mirror is moved along the vertical axis. When the projection point from the nose point to the makeup mirror plane falls on the horizontal axis, the position of the makeup mirror at this time is the adjusted target position.

[0072] In summary, the sun visor makeup mirror adjustment control method provided in the embodiment of this specification obtains the facial image data of the passenger taken by a three-dimensional camera; then, according to the facial image data, the left and right eye points and nose points of the passenger are determined; then, according to the left and right eye points and nose points of the passenger, the initial position of the makeup mirror is first adjusted; finally, according to the nose point, the adjusted initial position of the makeup mirror is second adjusted to determine the target position of the makeup mirror. By adjusting the rotation and translation control of the makeup mirror, the makeup mirror is adaptively adjusted, and the passenger does not need to move his body to adapt to the makeup mirror. No matter how the position of the passenger changes, the complete face can be seen in the makeup mirror and the facial image is centered.

[0073] Based on the same inventive concept, Figure 3 As shown, an embodiment of the present invention further provides a sun visor cosmetic mirror adjustment control device, comprising: an acquisition module, a processing module, a first adjustment module and a second adjustment module.

[0078] In an optional implementation, the first adjustment module is further used for:

[0079] According to the left and right eye points of the passenger, determine the center point of the left and right eye points and the connecting line of the left and right eye points;

[0080] According to the line connecting the left and right eye points and the nose point, rotate the makeup mirror around the horizontal axis and the vertical axis respectively;

[0081] The makeup mirror is translated according to the preset viewing distance and the center points of the left and right eye points.

[0082] In an optional implementation, the first adjustment module is further used for:

[0083] Rotate the vanity mirror around its longitudinal axis until its transverse axis is parallel to the line connecting the left and right eye points of the passenger;

[0084] The makeup mirror is rotated around the horizontal axis so that the difference between the vertical distance from the nose point to the makeup mirror plane and the vertical distance from the left eye point to the makeup mirror plane is within a preset difference range, or the difference between the vertical distance from the nose point to the makeup mirror plane and the vertical distance from the right eye point to the makeup mirror plane is within a preset difference range.

[0085] In an optional implementation, the first adjustment module is further used for:

[0086] According to the preset viewing distance, adjust the vertical distance from the center point of the left and right eye points to the makeup mirror;

[0087] Move the makeup mirror along the horizontal axis so that the projection points of the center points of the left and right eye points on the makeup mirror are on the vertical axis of the makeup mirror.
