Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application unless it is specifically stated otherwise.
The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses.
Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
As shown in fig. 1, the VR device is provided with two lens barrels, which correspond to two eyes of a person one by one. For any lens barrel and an image to be imaged by the lens barrel, the closer the projection of the optical center C0 of the lens in the lens barrel on the display screen is to the first center C1 of the image on the display screen, the clearer the image in the imaging result is viewed by a user through the lens barrel; conversely, the farther the projection of the optical center C0 of the lens in the barrel onto the display screen is from the first center C1 of the image on the display screen, the more blurred the image in the imaging result is viewed by the user through the barrel.
As shown in fig. 1, the interpupillary distance (the distance between the second center C21 of the left-eye pupil and the second center C22 of the right-eye pupil) of the person is not the same, and is generally in the range of 53cm to 73cm, in which case, if the distance between the two lens barrels is fixed, the interpupillary distance of the person may appear to be moderate (the interpupillary distance is equal to the distance between the two lens barrels), the interpupillary distance is large (the interpupillary distance is greater than the distance between the two lens barrels), and the interpupillary distance is small (the interpupillary distance is smaller than the distance between the two lens barrels). Based on the design that the distance between two lens barrels on VR equipment is adjustable, the user can adjust the distance between the lens barrels according to own interpupillary distance for the relationship between own interpupillary distance and the distance between two lens barrels is that the interpupillary distance is moderate. Meanwhile, in order to ensure the definition of the image in the imaging result watched by the user, the display screen is also designed to be adjustable in image position.
As shown in (1) to (3) in fig. 2, a display area a is provided in the display screen of the VR device, and the display area a may be a left-eye display area A1 or a right-eye display area A2, the left-eye image is displayed in the left-eye display area A1, and the right-eye image is displayed in the right-eye display area A2. For any display area a, the area of the display area a is larger than the area of the image displayed in the display area a, so that the position of the image in the display area a can be changed according to actual needs.
With continued reference to fig. 2 (1) to (3), the display position of the image in the display area a is variable. In the horizontal direction, as shown in (1) of fig. 2, the center position (first center C1) of the image in the display area a may be left-shifted with respect to the center position (third center C3) of the display area a; as shown in (2) of fig. 2, the center position of the image in the display area a may coincide with the center position of the display area a; as shown in (3) of fig. 2, the center position of the image in the display area a may be offset to the right with respect to the center position of the display area a.
Based on the design of the display screen, the position of the image in the display screen can be adjusted, so that the center of the pupil of the human eye, the optical center of the lens in the lens barrel and the center of the image in the display screen are positioned on the same straight line, and the image in the imaging result observed by the user is a clear image.
However, in actual situations, the distance between the two lens barrels is detected by using a magnet based on the hall effect, so that the accuracy of the detection result is poor, and a part of users cannot obtain clear display images, which causes discomfort to the users.
Based on the above problems, the present application provides a display control method, apparatus, display device, electronic device, and computer readable storage medium for a display device, so as to solve the problem of insufficient image clarity in imaging results of a part of users in the display device provided with two lens barrels.
Fig. 3 is a flowchart of a method for controlling display of a display device according to some embodiments of the present application.
As shown in fig. 3, the method includes the following steps S310 to S340.
Step S310: controlling the optical signal transceiver to transmit the detection signal and receive the reflected signal; the reflected signal is obtained by reflecting the detection signal by the optical signal reflector.
Before the introduction step S310, the display device in the present application is first described.
The display device in the present application includes a first barrel, a second barrel, an optical signal transceiver provided on the first barrel, and an optical signal reflector provided on the second barrel. The optical signal transceiver and the optical signal reflector are arranged opposite to each other so that an optical signal emitted from the optical signal transceiver can reach the optical signal reflector and be reflected by the optical signal reflector back to a position in the optical signal transceiver for receiving the optical signal.
In some examples, the optical signal transceiver is disposed on an outer wall of the first barrel and the optical signal reflector is disposed on an outer wall of the second barrel.
As shown in fig. 4, the display apparatus 40 includes a first barrel 41, a second barrel 42, an optical signal transceiver 43, an optical signal reflector 44, and a display screen 45. Wherein the optical signal transceiver 43 is disposed on the outer wall of the first barrel 41, and the optical signal reflector 44 is disposed on the outer wall of the second barrel 42. The optical signal transceiver 43 and the optical signal reflector 44 are disposed in a spaced-apart opposition.
Of course, it is understood that the arrangement of the optical signal transceiver 43 and the optical signal reflector 44 shown in fig. 4 is merely exemplary. The arrangement of the optical signal transceiver and the optical signal reflector in the embodiment of the present application includes, but is not limited to, the manner shown in fig. 4, for example, a first lens barrel is provided with a first through hole, a second lens barrel is provided with a second through hole, the optical signal transceiver is fixed on an inner wall of the first lens barrel, at least part of the optical signal transceiver (a part for transmitting an optical signal and receiving an optical signal) is exposed to air through the first through hole, the optical signal reflector is fixed on an inner wall of the second lens barrel, and at least part of the optical signal reflector is exposed to air through the second through hole.
The first barrel 41 and the second barrel 42 are used to image a first image 46 and a second image 47 displayed on the display screen 45, respectively. Wherein the first lens barrel 41 is used for imaging the first image 46, and a user can watch the imaging result of the first lens barrel 41 on the first image 46 through the first lens barrel 41; the second barrel 42 is used for imaging the second image 47, and a user can view the imaging result of the second barrel 42 on the second image 47 through the second barrel 42.
In some examples, the first barrel 41 is a left eye barrel corresponding to a left eye of a user, and the second barrel 42 is a right eye barrel corresponding to a right eye of the user.
In other examples, the first barrel 41 is a right eye barrel corresponding to the right eye of the user, and the second barrel 42 is a left eye barrel corresponding to the left eye of the user.
The distance between the first barrel 41 and the second barrel 42 is adjustable, and the implementation manner of the adjustment may be set by those skilled in the art according to actual situations, which is not limited by the embodiment of the present application.
In some examples, as shown in fig. 5, the optical signal transceiver 43 includes a transmitting unit 431 and a receiving unit 432. The transmitting unit 431 is configured to transmit a detection signal, and the detection signal is reflected by the optical signal reflector 44 to the receiving unit 432 when transmitted to the optical signal reflector 44.
The number of the transmitting units 431 may be one. The number of the receiving units 432 may be one or more (only one receiving unit 432 is shown in fig. 5 by way of example), so as to ensure the probability that the optical signal transceiver 43 receives the detection signal (i.e., the reflected signal) reflected by the optical signal reflector 44 to the greatest extent, and improve the response efficiency.
The optical signal transceiver 43 may be a device capable of receiving and transmitting an optical signal (i.e., a detection signal) such as a photoelectric sensor, and the optical signal reflector 44 may be a device capable of reflecting an optical signal such as a gray card.
The setting position of the optical signal transceiver 43 on the outer wall of the first barrel and the setting position of the optical signal reflector 44 on the outer wall of the second barrel are set by those skilled in the art according to the actual situation, so long as the detection signal sent by the transmitting unit 431 on the optical signal transceiver 43 can be reflected by the optical signal reflector 44 back to the receiving unit 432 of the optical signal transceiver 43.
In step S310, the optical signal transceiver may be controlled to transmit the detection signal and receive the reflection signal at preset time intervals, or may be controlled to transmit the detection signal and receive the reflection signal in the case where it is detected that the first barrel and the second barrel are adjusted. The preset time interval and the manner of detecting whether the first lens barrel and the second lens barrel are adjusted may be set by those skilled in the art according to actual situations, which is not limited in the embodiment of the present application.
Step S320: the time interval between the transmission of the detection signal and the reception of the reflected signal by the optical signal transceiver is calculated.
As shown in fig. 5, the transmitting unit 431 in the optical signal transceiver 43 transmits a detection signal, which changes its propagation path after being reflected by the optical signal reflector 44, and becomes a reflected signal under this condition. When the preset time interval is larger than the time interval between the sending of the detection signal and the receiving of the reflection signal by the optical signal transceiver, the time when the detection signal is sent can be recorded as the first time, the time when the reflection signal is received is recorded as the second time, and the time difference between the second time and the first time is obtained as the time interval; when the preset time interval is smaller than the time interval between the transmission of the detection signal and the reception of the reflection signal by the optical signal transceiver, the time when the detection signal is transmitted for the nth time can be recorded as the first time, the time when the reflection signal is received for the nth time can be recorded as the second time, and the time difference between the second time and the first time can be obtained as the time interval. Wherein n is a natural number and n >0.
Step S330: calculating the center distance between the lens barrel center of the first lens barrel and the lens barrel center of the second lens barrel according to the time interval; wherein the center of the lens barrel is the optical center of the lens in the lens barrel.
For example, referring to fig. 4, the distance of the optical signal transceiver 43 and the optical signal reflector 44 in the horizontal direction may be taken as the first distance d1, and a first relationship between the actual distance of the detection signal propagating from the optical signal transceiver 43 to the optical signal reflector 44 and the first distance may be set in advance according to the setting positions of the optical signal transceiver 43 and the optical signal reflector 44 on the corresponding barrel outer walls, in which case the actual distance may be calculated according to the time interval, and then the first distance d1 may be calculated according to the actual distance and the first relationship described above.
For example, it may be considered that the detection signal travels back and forth along the actual path from the optical signal transceiver 43 to the optical signal reflector 44, in which case the time interval is t and the propagation speed of the detection signal is v, and the actual path s1 may be calculated by the following formula:
s1＝(v×t)/2。
After the actual distance is obtained, the first distance can be obtained according to a first relation between the preset actual distance and the first distance. After that, the center distance is obtained from the first distance and a second relationship of the preset first distance and center distance.
For example, referring to fig. 4, a first distance between the optical signal transceiver 43 and the optical signal reflector 44 in fig. 4 is d1, a center distance between a barrel center of the first barrel and a barrel center of the second barrel is d2, and a relationship of the first distance d1 and the center distance d2 can be approximately regarded as the following relationship:
d2＝d1+d3+d4；
Where d3 is a second distance from the optical signal transceiver 43 to the barrel center of the first barrel, and d4 is a third distance from the optical signal reflector 44 to the barrel center of the second barrel.
Step S340: and adjusting the positions of the first image and the second image of the display screen according to the center distance so that the image center of the first image coincides with the first projection of the lens barrel center of the first lens barrel on the display screen and the image center of the second image coincides with the second projection of the lens barrel center of the second lens barrel on the display screen.
In some examples, as shown in fig. 6, the execution of step S330 may include the following steps S610 to S630:
Step S610: and determining a first position of the lens barrel center of the first lens barrel and a second position of the lens barrel center of the second lens barrel according to the center distance.
A coordinate system can be established in advance, then a first coordinate of the lens barrel center of the first lens barrel is determined in the coordinate system established in advance according to the center distance, and a position corresponding to the first coordinate is taken as a first position; and determining a second coordinate of the lens barrel center of the second lens barrel in a pre-established coordinate system, and taking a position corresponding to the second coordinate as a second position.
Step S620: a first projection position of the first position on the display screen and a second projection position of the second position on the display screen are obtained.
A plane passing through the barrel centers of the first barrel and the second barrel may be regarded as a barrel center plane, and a second relationship of each coordinate position on the barrel center plane and a projection coordinate position corresponding to the coordinate position on the display screen may be set in advance based on the above-described coordinate system. When executing step S620, a first projection coordinate corresponding to the first coordinate on the display screen can be obtained according to the first coordinate and the second relation, and the position where the first projection coordinate is located is taken as a first projection position; and obtaining a second projection coordinate corresponding to the second coordinate on the display screen according to the second coordinate and the second relation, and taking the position of the second projection coordinate as a second projection position.
Step S630: and adjusting the image center of the first image to a first projection position and the image center of the second image to a second projection position in the display screen.
And translating the first image and the second image in the horizontal direction, so that the coordinates of the image center of the translated first image are coincident with the first projection coordinates, and the coordinates of the image center of the second image are coincident with the second projection coordinates.
In some embodiments, as shown in fig. 7, the step S330 execution may include the following steps S710 to S740.
Step S710: and acquiring a history center distance between the barrel center of the first barrel and the barrel center of the second barrel which are recorded currently.
The history center distance is the distance between the barrel center of the current first barrel and the barrel center of the second barrel. The history center distance is stored in a preset storage location from which it can be retrieved directly. The history center distance acquired from the storage location for the first time is the initial center distance stored in advance. That is, in the case where the user never adjusts the distance between the barrel center of the first barrel and the barrel center of the second barrel, the distance is taken as the initial center distance after precisely measuring the distance between the barrel center of the first barrel and the barrel center of the second barrel in advance.
Step S720: a difference between the center distance and the historical center distance is calculated.
Step S730: and determining the moving distance and the moving direction of the first image and the second image according to the difference value.
For example, in the case where the difference is greater than zero, the moving direction of the left-eye image is determined to be leftward, the moving direction of the right-eye image is determined to be rightward, and the moving distance of the first image and the second image is determined to be one half of the absolute value of the difference.
And under the condition that the difference value is smaller than zero, determining that the moving direction of the left eye image is rightward, the moving direction of the right eye image is leftward, and the moving distance of the first image and the second image is one half of the absolute value of the difference value.
In the case where the difference is equal to zero, the moving distance of the first image and the second image is determined to be 0, that is, the positions of the first image and the second image are not adjusted.
Step S740: and adjusting the positions of the first image and the second image according to the determined result.
The first image is moved by a movement distance of the first image in a movement direction of the first image, and the second image is moved by a movement distance of the second image in a movement direction of the second image.
