With the continuous development of display technology, naked eye three-dimensional (3D) displays are becoming more mature and provide viewers with a good 3D experience.
However, in the related art, the naked-eye 3D display device is generally unable to adjust the angle of the display screen.

Therefore, regarding the problem, in the related art, a display screen with a fixed angle is generally manufactured to avoid the problem that the angle of the entire 3D picture changes after the inclination angle of the display screen is adjusted.

The embodiment of the application provides a parameter processing method, and an execution main body of the method can be various terminal devices or server devices with parameter processing capacity, and can also be devices or chips integrated on the devices. As shown in fig. 2, which is a schematic flow chart of a parameter processing method provided in an embodiment of the present application, the method includes the following steps:
s201: the method comprises the steps of obtaining a first angle of first display equipment and a second angle corresponding to the first display equipment.
Wherein the first angle comprises a tilt angle of the first display device; the second angle comprises a preset reference angle corresponding to the first display device.
Optionally, the embodiment of the present application may be applied to the field of three-dimensional (3-dimensional, 3D) stereoscopic view display, for example, the present application may be specifically applied to a naked-eye 3D display scene.
Wherein the first display device may comprise a three-dimensional view display device. Alternatively, the first display device may be a display screen displaying a three-dimensional view. For example, in a naked eye 3D display scene, the first display device may be a naked eye 3D display screen.
In the embodiment of the application, the angle between the first display device and the reference surface can be adjusted. For example, the first display device may be disposed at an angle of 90 degrees with respect to the horizontal plane, i.e., the first display device is disposed perpendicular to the horizontal plane; alternatively, the first display device may be arranged at an angle of 120 degrees to the horizontal, i.e. the first display device is arranged inclined to the horizontal, etc.
In the embodiment of the application, the first angle is an angle between the first display device and the reference plane when the three-dimensional view is displayed. Wherein, the reference plane may include a horizontal plane, a vertical plane, and the like; alternatively, in the embodiment of the present application, for convenience of description, the reference plane may be a horizontal plane. It will be appreciated that the first angle is variable with adjustment of the first display device.
In order to obtain a first angle between a first display device and a reference plane (horizontal plane) in real time, a preset angle sensor may be provided at a predetermined position of the first display device, and the first angle may be determined by an angle parameter measured by the preset angle sensor. Alternatively, the preset angle sensor may include an angle sensor such as a gyroscope or a rotary slide rheostat.
In addition, the second angle is a preset reference angle corresponding to the first display device. Specifically, when the first display device is disposed at the second angle, the position coordinates of the reference object in the coordinate system of the plane where the first display device is located are the same as the position coordinates of the reference object in the coordinate system of the plane where the vertical plane is located. That is, when the first display device is set at the second angle, the three-dimensional view viewed by the user is the best. In this embodiment of the application, the reference object may be an eye of a user who views a three-dimensional view (hereinafter referred to as a human eye for short).
S202: according to the first angle and the second angle, correcting the display parameters of the first display device to obtain correction parameters, and displaying a three-dimensional view based on the correction parameters; wherein the display parameters include a position parameter of a reference with respect to the first display device.
In particular, the display parameters may include related parameters for displaying the three-dimensional view. Optionally, in this embodiment of the application, the display parameter may be a position parameter of the reference object with respect to the first display device. Wherein, the reference object can be human eyes. Alternatively, the position parameter of the human eye relative to the first display device (hereinafter, may be referred to as a first position parameter) may be a coordinate of the human eye in a coordinate system of a plane in which the first display device is located.
Further, the correction parameter includes a position parameter of the virtual image pickup apparatus when the first display apparatus is set at the first angle. The virtual camera shooting device is used for acquiring a three-dimensional view.
In a naked eye 3D display scene, the position of the virtual camera equipment can be determined according to the position of human eyes. When the first display device is arranged at the second angle, the position coordinates of the human eyes in the real space are the position coordinates of the virtual camera shooting device in the virtual space. In this way, when the virtual camera device acquires the three-dimensional view at the position, a better three-dimensional view effect can be presented to the user.
In the embodiment of the present application, after the first angle is obtained, the display parameter of the first display device may be corrected according to the first angle and the second angle to obtain a correction parameter, so as to display the three-dimensional view based on the correction parameter. Therefore, under the condition that the watching position of the user is not changed, the first display device can present a better watching effect to the user at the first angle.
Specifically, the display parameter may be corrected according to an offset angle between a first angle and a second angle, so as to obtain the correction parameter, and a three-dimensional view may be displayed based on the correction parameter.
For example, in an actual scene, the preset reference angle (i.e., the second angle) corresponding to the first display device is 90 degrees; when the user actually views the three-dimensional view, the inclination angle (i.e., the first angle) of the first display device is 120 degrees; in this case, the coordinates (i.e. the display parameters) of the human eye in the coordinate system of the plane where the first display device is located may be corrected according to the offset angle between the first angle and the second angle, i.e. the offset angle is 120-90 degrees to 30 degrees, so as to obtain corrected coordinates (i.e. the correction parameters); then, the virtual camera apparatus may be set at a coordinate position corresponding to the correction parameter to acquire a three-dimensional view and display the three-dimensional view to the user.
It should be noted that, because the first angle of the first display device can be adjusted at any time, in the embodiment of the present application, the obtaining of the first angle in the above step, and the correction processing performed on the display parameter of the first display device according to the first angle and the second angle can be performed in real time, so as to present a better viewing effect to the user.
In the embodiment of the application, a first angle of a first display device and a second angle corresponding to the first display device are obtained; according to the first angle and the second angle, correcting the display parameters of the first display device to obtain correction parameters, and displaying a three-dimensional view based on the correction parameters; the angle of the first display equipment can be adjusted at any time, and after adjustment, under the condition that the watching position and the watching angle of a user are unchanged, the first display equipment can present a better watching effect of a three-dimensional view to the user when being positioned at any first angle.
In an embodiment of the application, the obtaining the first angle of the first display device includes:
acquiring an angle parameter measured by a preset angle sensor, and determining the first angle according to the angle parameter; the preset angle sensor is arranged at a preset position of the first display device.
In the embodiment of the application, the inclination angle (i.e. the first angle) of the first display device can be freely adjusted, so that the user can obtain a comfortable viewing experience by adjusting the first angle of the first display device.
Specifically, in the embodiment of the present application, the first angle may be determined by an angle parameter measured by a preset angle sensor. Wherein the preset angle sensor may be disposed at a predetermined position of the first display device. Optionally, the preset angle sensor may include an angle sensor such as a gyroscope or a rotary rheostat.
By way of example, embodiments of the present application are described with reference to fig. 3:
the naked-eye 3D device shown in fig. 3 includes a base, a display screen (i.e., the first display device of the embodiment of the present application), and a preset angle sensor.
The base is used for supporting the display screen; the display screen can rotate around the base, so that the angle between the display screen and the horizontal plane can be freely adjusted.
The display screen comprises a display module, a lens grating or a barrier grating and other components; the display screen is used to present a three-dimensional view.
The preset angle sensor is used for acquiring an angle between the display screen and a horizontal plane. The preset angle sensor may include a gyroscope or a rotary rheostat or the like.
The setting of the preset angle sensor can be divided into two cases. Wherein, as one case: the preset angle sensor may be a gyroscope, and the gyroscope may be disposed inside the display screen. The included angle between the display screen and the horizontal plane can be obtained in real time through the gyroscope. Or, as another case: the preset angle sensor may be a rotary slide rheostat. As shown in fig. 3, the rotary type slide rheostat can be arranged at the connection position of the display screen and the base; it can be understood that the rotary slide rheostat is movably connected with the base. When the display screen rotates relative to the base, the resistance value (or the current value) change value of the rotary slide rheostat is converted into an angle change value, so that a first angle between the display screen and a horizontal plane can be measured.
In one embodiment of the present application, the method further comprises:
acquiring first position information of a reference object in a coordinate system of a plane where the first display device is located;
and determining the display parameters according to the first position information.
Specifically, the display parameter may be a position parameter of the reference object with respect to the first display device. Wherein, the reference object can be human eyes. Optionally, the position parameter of the human eye relative to the first display device may be a coordinate of the human eye in a coordinate system of a plane in which the first display device is located.
As an example, a coordinate system of a plane on which the first display device is located (hereinafter, simply referred to as an eye tracking coordinate system) will be described with reference to fig. 4:
as shown in fig. 4, fig. 4 is a schematic diagram of setting an eye tracking coordinate system, where the eye tracking coordinate system uses the center of the display screen (i.e., the first display device) as an origin, the display screen plane as an XY-axis plane, the positive X-axis direction as the horizontal right of the display screen, the positive Y-axis direction as the upward along the display screen plane, and the positive Z-axis direction as the right front of the display screen.
In the embodiment of the present application, the display parameter is a coordinate (i.e., first position information) of the human eye in the human eye tracking coordinate system.
In an embodiment of the application, the acquiring first position information of the reference object in a coordinate system of a plane where the first display device is located includes:
acquiring a user image through preset image acquisition equipment;
and determining the first position information according to the user image.
In the embodiment of the application, the reference object may be a human eye, and when first position information of the human eye in a coordinate system of a plane where the first display device is located is determined, a user image may be acquired through a preset image acquisition device; and determining the first position information according to the user image.
The preset image acquisition equipment can be eye tracking equipment; the eye tracking device comprises a camera and an associated chip. The camera may be a camera with depth recognition capability, such as a Time of Flight (TOF) camera. The camera and the display screen (namely the first display device) are relatively fixed, and when the display screen rotates, the human eye tracking device also rotates relative to the rotation center.
Specifically, the user image can be acquired through the human eye tracking camera, and the human eye coordinate of the user is acquired by identifying and analyzing the user image.
In an embodiment of the application, the correcting the display parameter of the first display device according to the first angle and the second angle to obtain a corrected parameter includes:
determining an offset angle between the first angle and the second angle;
and correcting the display parameters according to the offset angle to obtain the correction parameters.
In particular, the offset angle is used to characterize the angular difference between the first angle and the second angle. According to the embodiment of the application, the display parameters can be corrected according to the angle difference to obtain the correction parameters. The correction parameter is a position parameter of the virtual camera device when the first display device is at the first angle.
It can be understood that the display parameters are corrected based on the offset angle to obtain the position parameters of the virtual camera device when the first display device is at the first angle, so that the virtual camera device acquires the three-dimensional view based on the position parameters, and thus, a better three-dimensional view playing effect can be presented to a user.
In one embodiment of the application, the display parameters comprise first position information of the reference object in a coordinate system of a plane in which the first display device is located,
the correcting the display parameter according to the offset angle to obtain the correction parameter includes:
determining the correction parameter according to the offset angle, the display parameter and a first data relation;
the first data relationship includes:
wherein (x1, y1, z1) represents first position information of the reference object in a coordinate system of a plane in which the first display device is located,
(x2, y2, z2) represents the correction parameter, θ1Representing the component of said offset angle in the direction of the X-axis, theta2Representing the component of said offset angle in the direction of the Y-axis, theta3A component of the offset angle in the Z-axis direction.
Specifically, in the embodiment of the present application, the reference object is a human eye, and by way of example, with reference to fig. 5 and 6, a preset reference angle (second angle) is taken as a 90-degree angle from the horizontal plane, and only an offset in the X-axis direction exists between the first angle and the second angle, that is, θ2＝0、θ3The description is given by way of example with 0:
as shown in fig. 5, fig. 5 is a schematic view illustrating a coordinate system of a plane (hereinafter referred to as a real space coordinate system) where a predetermined reference angle is located. The real space coordinate system takes the center of the display screen (namely, the first display device) as an original point, when a viewer looks at the display screen, the right of the viewer is the positive direction of an X axis, the negative direction of gravity is the positive direction of a Y axis, and the direction from the display screen to the viewer is the positive direction of a Z axis.
As shown in fig. 6, in the example of the embodiment of the present application, the first display device is obliquely disposed at an angle ψ from a horizontal plane, that is, the first angle of the first display device is ψ. It is to be understood that the first display device may be understood as being reclined on the basis of the second angle, corresponding to the first angleThe display device is rotated around the X-axis in the real space coordinate system by ψ -90 °, i.e. the offset angle θ between the first angle and the second angle is θ1＝ψ-90°(θ2＝0、θ30). That is, the first angle corresponds to a rotation by an angle θ along the X-axis based on the second angle1。
Since the first angle is rotated by an angle theta along the X-axis based on the second angle1When the display parameters are corrected, the display parameters, that is, the coordinates of the human eye in the coordinate system of the plane where the first display device is located, may be corrected to the coordinates of the human eye in the coordinate system of the real space.
And because the rotation of the first angle on the basis of the second angle is linear transformation, the coordinates of the human eyes relative to the real space coordinate system when the first display equipment is arranged at the first angle can be determined through the transformation of the rotation matrix. In the embodiment of the present application, the coordinates of the human eye in the real space coordinate system are the correction parameters in the embodiment of the present application.
