Hereinafter, the method for adjusting the height provided by the present application will be described in detail.

Fig. 2 is a schematic flow chart of a method 200 for adjusting height according to an embodiment of the present application. As shown in fig. 2, method 200 includes the following steps.

S201, adjusting a relative height between the display device and a human eye height of the user in response to the user information. The relative height is related to the height of the display device and the height of the eyes of the user, wherein the height of the display device is the height of the center of the window unit of the display device relative to the ground of the cabin, and the height of the eyes of the user is the height of the eyes of the user relative to the ground of the cabin.

In the scheme of the application, the relative height between the display device and the human eye of the user can be adjusted by adjusting the height of the display device, or the relative height between the display device and the human eye of the user can be adjusted by adjusting the height of the human eye.

In the present application, the user information includes, but is not limited to, at least one of: the height of the user's eyes, the height of the user, the position of the eyes in the image, and the weight of the user. When the eye height of the user is the height of the eye (or the eye sight line or pupil center, etc.) relative to the cabin floor, the eye height is the height of the eye in front of the eye head-up.

Optionally, before S201, the method further includes S202.

S202, user information is acquired.

In the scheme of the application, the user information can be acquired by receiving the sensing equipment from the cabin. When the obtained user information is the height or height of eyes, in one possible implementation manner, the height or sitting height of eyes of the passengers relative to the floor of the cabin can be estimated by recording the states of the passengers in the cabin and the cameras or the like recording the images in the cabin in real time and by shooting the images of the passengers in the sitting state. Or in another implementation, the height, angle or height of the human eye can be estimated by capturing an image of the human eye when the passenger is in a sitting position by an image sensor provided in the display device, for example, a camera for capturing and tracking the human eye, or the like. When the acquired user information is weight, the weight of the user can be acquired through a weight detector on a cabin pedal or a seat.

Fig. 3 is a schematic flow chart of a method 300 for adjusting height according to an embodiment of the present application. It is to be appreciated that the method 300 may be performed by the first seat, or by a processing device in the first seat, or by a processing chip in the first seat, or the like, or by a cabin domain controller for adjusting the first seat and sending an adjustment message to a means for adjusting the first seat, as the application is not limited. The method 300 provided by the present application is described below with the first seat as the execution subject, and as shown in fig. 3, the method 300 includes the following steps.

And S301, responding to the user information, adjusting the first seat to a first target height, wherein the first target height is the height of a part of structures of the first seat relative to the ground of the cabin, and the first seat is a seat for installing a display device.

In the scheme of the application, the first target height is used for meeting the requirement that a user is in a viewing angle range when viewing a virtual image of the display device. I.e. when the first seat is adjusted to the first target height, the user can be enabled to view the complete image displayed by the display device.

When the display device is installed in the seatback of the first seat, ways to adjust the first seat to the first target height in response to the user information include, but are not limited to: the seat cushion of the first seat is lifted or lowered according to the user information, and meanwhile, the seat back of the first seat is driven to be lifted or lowered to the first target height. At this time, the first target height is the height of the horizontal plane of the seat cushion of the first seat relative to the cabin floor. Or the first seat raises or lowers the seat back of the first seat to a first target height, etc., according to the user information. At this time, the first target height may be a height of a horizontal plane where a back center of the first seat is located with respect to the cabin floor, or the first target height may be a height of a horizontal plane where a back top end of the first seat is located with respect to the cabin floor, or the like.

Ways of adjusting the first seat to the first target height in response to the user information when the display device is installed in the headrest of the first seat include, but are not limited to: the first seat drives the headrest of the first seat to rise or fall to the first target height at the same time when the seat cushion of the first seat is raised or lowered according to the user information. At this time, the first target height is the height of the horizontal plane of the seat cushion of the first seat relative to the cabin floor. Or the first seat drives the headrest of the first seat to rise or fall simultaneously while the seat back of the first seat rises or falls according to the user information. At this time, the first target height may be a height of a horizontal plane where a back center of the first seat is located with respect to the cabin floor, or the first target height may be a height of a horizontal plane where a back top end of the first seat is located with respect to the cabin floor, or the like. Or the first seat raises or lowers the headrest of the first seat, or the like, according to the user information. At this time, the first target height may be a height of a horizontal plane in which a headrest center of the first seat is located with respect to the cabin floor, or the first target height may be a height of a horizontal plane in which a headrest tip of the first seat is located with respect to the cabin floor, or the like.

Optionally, before S301, the method further includes S302.

S302, user information is acquired.

Specifically, the manner in which the first seat obtains the user information may refer to the description of obtaining the user information in S202, which is not described herein.

Fig. 4 is a schematic flow chart of a method 400 for adjusting a height of a first seat to a first target height according to an embodiment of the present application. It is to be appreciated that the method 400 may be performed by a processing device of the first seat, which may be a processor, or a processing module in a processing device, such as a chip or the like, or by a cabin controller or the like, as the application is not limited. The processing apparatus of the first seat will be specifically described below as an example. As shown in fig. 4, method 400 includes the following steps.

S401, acquiring a first height H1 of the first seat.

Specifically, the processing device of the first seat acquires the current height H1 of the first seat (i.e., the height before the adjustment). The processing device of the first seat may, for example, obtain the current height H1 of the first seat from the seat height information stored in the storage unit of the cabin. The seat height information may be a height value of the first seat after the previous adjustment, or an adjustment value of the last seat, etc., which is not limited by the present application. When the seat height information acquired by the processing device of the first seat through the storage unit of the cabin is the height value adjusted in the previous time, the processing device of the first seat takes the height value as the current height H1 of the first seat. When the seat height information acquired by the processing device of the first seat through the storage unit of the cabin is the adjustment value of the last seat, the processing device of the first seat can calculate and generate the current height H1 according to the preset initial value and the adjustment value of the first seat. Wherein, the last adjustment value of the seat can be positive or negative or 0. Wherein, the adjustment value is positive, which can indicate that the last time the seat is adjusted upwards relative to the initial position; when the adjustment value is negative, the last downward adjustment of the seat relative to the initial position can be indicated; when the adjustment value is 0, it may indicate that the seat was not adjusted with respect to the initial position last time. For example, when the adjustment value is-6 mm and the initial value of the first seat is 764.4mm, the processing apparatus of the first seat calculates that the height H1 that can be present is 758.4mm. It should be noted that, when the processing apparatus of the first seat may calculate the height H1 from a preset initial value of the first seat, the preset initial value of the first seat may be preset in the processor.

S402, determining a first target height of the first seat based on user information.

Specifically, the processing device of the first seat determines a first target height of the first seat based on the user information.

S403, an adjustment amount Δh1 of the height of the first seat is determined based on the first height H1 and the first target height.

Specifically, after the processing apparatus of the first seat acquires the first height H1 and the first target height, the adjustment amount Δh1 of the height of the first seat is determined based on the first height H1 and the first target height.

S404, adjusting the height to the first target height according to the adjustment quantity delta H1.

Specifically, after the processing apparatus of the first seat determines the adjustment amount Δh1 of the height of the first seat, the height is adjusted to the first target height according to the adjustment amount Δh1. For example, the processing device of the first seat may send the adjustment quantity Δh1 to a control device or an adjustment device (for example by means of an adjustment message), with which the height of the first seat is adjusted to the first target height.

It should be noted that, the above-mentioned S401 and S402 are not strictly sequential, and S401 may be executed first and S402 may be executed second; or S402 is performed first and S401 is performed next; or S401 and S402 are performed simultaneously.

Next, a method for determining a first target height by the processing apparatus for a first seat according to an embodiment of the present application based on user information will be described in detail with reference to tables 1 to 6 and fig. 5.

In one implementation, the processing device of the first seat may determine the first target height from a first correspondence of user information and the first target height.

Optionally, the first correspondence is a correspondence between a human eye height value and a first target height, as shown in table 1 below; or the first correspondence is a correspondence between the height value and the first target height, as shown in table 2 below; or the first corresponding relation is the corresponding relation between the weight value and the first target height; or the first correspondence is a correspondence between the human eye height range and the first target height, as shown in table 4 below; or the first correspondence is a correspondence of the height range and the first target height, as shown in table 5 below; or the first correspondence is a correspondence between the weight range and the first target height.

For example, when the user information is a human eye height value, table 1 shows a correspondence relationship between a human eye height value and a first target height provided in the embodiment of the present application.

TABLE 1

In the present application, the eye height value refers to the height of the eye of the user relative to the floor of the cabin when the user sits on the rear seat.

For example, when the user information is a height value, table 2 shows a correspondence between a height value and a first target height provided by the embodiment of the present application.

TABLE 2

In the present application, the height refers to the height when the user stands vertically on the ground.

For example, when the user information is a weight value, table 3 shows a correspondence relationship between the weight value and the first target height provided in the embodiment of the present application.

TABLE 3 Table 3

For example, when the user information is the human eye height range, table 4 shows a correspondence relationship between the human eye height value and the first target height provided in the embodiment of the present application.

TABLE 4 Table 4

For example, when the user information is a height range, table 5 shows a correspondence between a height value and a first target height provided by the embodiment of the present application.

TABLE 5

For example, when the user information is a weight range, table 6 shows a correspondence relationship between a weight value and a first target height provided in the embodiment of the present application.

TABLE 6

It should be noted that, the above tables 1 to 6 are only examples and not limiting, and any basic modifications of the above tables 1 to 6 should be within the scope of the present application, for example, the correspondence between the sitting posture height and the first target height, or the range division of different human eye heights, height and weight, etc., and the present application is not limited thereto. It should be further understood that the data in tables 1 to 6 do not limit the protection scope of the present application, and the division of the scope may be uniform or non-uniform, which is within the protection scope of the present application.

In addition, the first correspondence relationship may be preset in the processing device or the storage device of the first seat, and the present application is not limited.

In another implementation, the processing device of the first seat may determine the first target height by the method 500 shown in fig. 5, taking into account the comfort of human eye viewing and in order to further enhance the user experience. As shown in fig. 5, method 500 includes the following steps.

S501, obtaining the distance D between the vertical plane where the eyes of the user are located and the vertical plane where the window unit is located.

Specifically, the processing device of the first seat may obtain the distance D between the vertical plane in which the eyes of the user are located and the vertical plane in which the window unit is located in a plurality of manners, which is not limited by the present application. The processing device of the first seat may, for example, obtain the distance D between the vertical plane in which the user's eyes lie and the vertical plane in which the window unit lies by receiving a distance detector from within the cabin, for example a camera within the cabin. Or the processing device of the first seat may obtain the distance D between the vertical plane in which the user's eyes are located and the vertical plane in which the window unit is located by receiving a distance detector from the display device, for example, a camera of the display device. Or the processing device of the first seat may obtain the preset distance D of the storage device, etc.

S502, determining a first target height based on the distance D, the viewing angle theta of human eyes and user information.

Specifically, as shown in fig. 6, after the processing device of the first seat obtains the distance D between the vertical plane in which the human eye is located and the vertical plane in which the window unit is located, the first target height h may be calculated based on the following formula (1).

h＝H′-Dtanθ (1)

In the above formula, H' is the height of the human eye in a sitting posture. Because in the scheme of the application, the user information can be the eye height, the height or the weight, and the like, when the user information acquired by the processing equipment of the first seat is not the eye height in sitting posture, the user information can be converted into the eye height H' in sitting posture. Illustratively, when the user information is the height H, since the sitting posture eye height of the human eye is generally about 47% of the height, and considering that the back reclining angle gamma ranges from 22.3 DEG.ltoreq.gamma.ltoreq.38.3 DEG, the height can be converted into the sitting posture eye height H' by the following formula (2).

H′＝0.47 ×Hcosγ (2)

In the present embodiment, the viewing angle θ includes a lower viewing angle θ1 or an upper viewing angle θ2. As shown in fig. 1, the lower viewing angle θ1 is an optimal viewing angle of the eye's line of sight with respect to the eye's lower horizontal plane when the eye is looking down, and the upper viewing angle θ2 is an optimal viewing angle of the eye's line of sight with respect to the eye's upper horizontal plane when the eye is looking up. Wherein, the value range of the lower visual angle theta 1 is-1.5 degrees or more and is less than or equal to 0 degrees or less, and the value range of the upper visual angle theta 2 is 0 degrees or more and is less than or equal to 9 degrees or less. In the present application, when the view angle value is negative, it means that the view angle is located below the horizontal line of sight of the human eye. When the viewing angle value is negative, the viewing angle is located above the horizontal line of sight of the human eye. When the viewing angle value is 0, the viewing angle is the horizontal line of sight of human eyes.

It should be noted that, in order to enhance the comfort level of the human eyes when viewing the display image, the present application provides an optimal comfortable viewing angle range for the human eyes at the lower viewing angle θ1 and the upper viewing angle θ2, and the optimal comfortable viewing angle is determined by the key factors affecting the optimal comfortable viewing angle as provided in the following table 7.

TABLE 7

As can be seen from table 7, factors affecting the optimal comfortable viewing angle of human eyes include the range of viewing angles α under the eyes and the head back tilt angle β. By collecting and analyzing a large amount of user data, the head back inclination angle beta is generally positioned at an angle of 0 degree or more and 16.1 degrees or less, and the angle of view alpha of the human eyes is generally positioned at an angle of 0 degree or more and 19.7 degrees or less.

Fig. 11 is a schematic flowchart of a method 1100 for adjusting an angle of a display device according to an embodiment of the present application. The method can be applied to the cabin virtual image display system shown in fig. 1. The method 300 may be performed by a display device, or by a processing apparatus in a display device, or by a processing chip in a display device, etc., and the application is not limited thereto. The method 1100 provided by the present application is described below with a display device as an execution subject, and as shown in fig. 11, the method 1100 includes the following steps.

S1101, acquiring the human eye position and the ideal human eye position in the image.

In the solution of the application, the way in which the display device obtains the position of the human eye and the ideal position of the human eye in the image may be obtained by receiving a sensor device from within the cabin. In one possible way, the position of the eyes in the image and the ideal position of the eyes in the image can be determined by recording the status of the passengers in the cabin in real time and by a camera or the like recording the images in the cabin, by taking the images of the passengers in a sitting position. Or in another realisable way the position of the human eye in the image and the ideal position of the human eye in the image may be determined by means of an image sensor provided in the display device, for example a camera or the like for capturing and tracking the human eye, by taking an image of the human eye when the passenger is in a sitting position.

S1102, an adjustment amount Δθ of the angle of the display device is determined based on the human eye position in the image and the ideal human eye position.

After the display device acquires the human eye position and the ideal human eye position in the image, the display device generates an adjustment quantity delta theta of the angle of the display device through digital image processing by determining a distance d between the human eye position and the ideal human eye position and according to a corresponding relation between the distance d and the adjustment quantity.

S1103, adjusting the angle of the display device according to the adjustment amount Δθ.

Specifically, after the adjustment amount Δθ is determined by the display device, the current angle is adjusted to an ideal position according to the adjustment amount Δθ, so that the human eye can be at the ideal position when viewing the image.

In the embodiment of the present application, the angle adjustment amount Δθ of the display device may be positive or negative, or may be 0. For example, when the adjustment amount Δθ is a positive number, it may indicate that the display device needs to be rotated upward with respect to the horizontal plane, when the adjustment amount Δθ is a negative number, it may indicate that the display device needs to be rotated downward with respect to the horizontal plane, and when the adjustment amount Δθ is 0, it may indicate that the display device does not need to be adjusted.

For example, as shown in (a) of fig. 12, when the human eye position in the display device acquired image is located above the ideal human eye position, the display device may determine the distance d between the human eye position and the ideal human eye position by an algorithm of image processing as shown in (b) of fig. 12, and calculate the adjustment amount Δθ of the angle of the generation display device according to the distance d. Subsequently, the display device performs angle adjustment according to the generated adjustment amount Δθ. It will be appreciated that when the display device completes the angle adjustment, as in fig. 12 (c), the eye position in the image obtained by the display device after the angle adjustment substantially coincides with the ideal eye position.

It should be noted that, the angle adjustment method for adjusting the height of the display device according to the embodiment of the present application may be used in combination with any one or more of the above-mentioned fig. 2 to 10. For example, when the relative height between the display device and the eye height of the user cannot continuously improve the experience such as eye comfort, the user's experience requirement can be met by adjusting the angle of the display device.

The method for adjusting the height according to the embodiment of the present application is described in detail above with reference to fig. 2 to 10, and the method for adjusting the angle according to the embodiment of the present application is described with reference to fig. 11 and 12. The display device and the processing apparatus provided by the embodiment of the application will be described in detail below with reference to fig. 13 and 14.

The image magnifying unit 1303 is configured to reflect the image light from the window unit 1002 to the window unit 1302.

Alternatively, in the present embodiment, the image magnification unit 1303 is a free-form surface mirror.

Specifically, when a passenger views a video image using the display device 1300, the image generating unit 1301 emits image light to the window unit 1302, the image light is reflected by the window unit 1302 and then is incident on the image amplifying unit 1303, and is reflected again by the image amplifying unit 1303 and then is incident on the window unit 1302, and the window unit 1302 is transmitted, and at this time, the passenger can see a large video image located at a distance through the window unit 1302.
