Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The naked eye 3D display screen generally adopts grating type and cylindrical lens technologies, and grating parameters or cylindrical lens parameters are universal. The raster parameters of the naked eye 3D display screen generally comprise the following parameters: slant: the angle between the grating or cylindrical lens and the vertical direction of the screen is described. A lens pitch: the number of sub-pixels covered by a single raster period or a single lenticular lens, or the physical width, representing the lens pitch by the number of sub-pixels covered, is required to provide the 3D display sub-pixel parameters at the same time, which are fixed when the raster or lenticular design is completed. render pitch: the horizontal direction arrangement period is expressed by the number of horizontal direction sub-pixels. The render pitch parameter is related to the lens pitch, slant and the observed distance. The closer the observation distance is to the render pitch, the smaller the observation distance is, and at infinity, the render pitch is the number of subpixels the lens pitch covers in the horizontal direction.
In an application scene of the scheme, the grating of the naked eye 3D display is extruded and stretched in the laminating processing process, the thickness of glue is uneven, and the pixel points in certain regions of the naked eye 3D display are not split according to an ideal model due to the fact that the pixels are influenced by the refractive index when the glue is watched in a close range. In this case, even if the interleaving parameters of the naked eye 3D display are completely correct, it is found that the contents displayed on the screen are not the same view, i.e. crosstalk is generated, thereby affecting the viewing effect of the naked eye 3D display.
Fig. 1 is a flowchart of a method for correcting a naked-eye 3D display screen according to an embodiment of the present invention, where the method may be performed by a device for correcting a naked-eye 3D display screen, where the device may be implemented by software and/or hardware, and the device may be configured in an electronic device for correcting a naked-eye 3D display screen. The method is applied to a scene for correcting the naked eye 3D display screen after leaving the factory. As shown in fig. 1, the technical solution provided by the embodiment of the present invention specifically includes:
and S110, determining the display content to be corrected in the calibration area in the 3D display screen.
Specifically, the calibration area may be a display area on the 3D display screen determined by the relative positions between the two eyes of the user and the screen, and it can be known from the principle of spectroscopic imaging of the naked-eye 3D display that when the relative positions between the two eyes of the user and the screen change, the calibration area changes accordingly, and accordingly, the display content received by the two eyes of the user changes accordingly. In order to ensure that the influence of ambient light on the calibration process of the display is minimum, the scheme is preferably realized in a darkroom, the calibration camera replaces two eyes of a user, the lens of the calibration camera needs to face the display screen, and the distance between the calibration camera and the screen is the optimal observation distance of the user. For example, the distance between the calibration camera and the screen may be set to 1.2m, the distance between the calibration camera and the screen may be set to 1.9m, and the distance between the calibration camera and the screen may be set according to actual needs. The calibration camera is a camera capable of shooting the display content of the display. The calibration camera may be a single camera, or may be a binocular camera, i.e., a stereo camera. The calibration camera can be set according to actual needs. The display content to be corrected can be display content which is obtained by the calibration camera at a fixed position away from the screen of the display before the naked eye 3D display is corrected and is determined by the naked eye 3D display according to the relative position of the calibration camera and the screen.
And S120, sequentially sending the first to-be-arranged views of a first preset number to the calibration area for displaying.
The first preset number may be 18, the first preset number may be 28, and the first preset number may be set according to actual needs. Since the solution is implemented in a darkroom, the first to-be-displayed view can be 1 full white view and 7 full black views. The first to-be-arranged view may also be a plurality of views, such as 28 grayscale images, obtained by weighting two adjacent to-be-arranged views of 1 full white view and 7 full black views through an interleaving algorithm. According to the scheme, the first to-be-arranged views with the first preset number can be sequentially sent to the calibration area to be displayed. Specifically, according to the light splitting principle of the naked eye 3D display, which to-be-arranged view of the arrangement position is displayed in the calibration area can be determined. Therefore, according to the scheme, the first to-be-arranged views with the first preset number can be ensured to be sequentially displayed in the calibration area only by sequentially placing the first to-be-arranged views with the first preset number at the arrangement position determined by the calibration area.
And S130, determining a projection image obtained at the corresponding position associated with the calibration area when each first to-be-arranged view is projected to the calibration area.
Specifically, the corresponding position associated with the calibration area may be a position of the calibration camera at a fixed distance from the display screen, for example, the corresponding position associated with the calibration area may be 1.2m from the calibration camera to the display screen, the corresponding position associated with the calibration area may be 1.9m from the calibration camera to the display screen, and the corresponding position associated with the calibration area may be set according to actual needs. According to the scheme, the projection image obtained when each first to-be-arranged view is projected to the calibration area can be obtained through the calibration camera arranged at the corresponding position. Wherein the display content of the whole display can be included in the projected image. Before the projection image is obtained, the original images obtained at the corresponding positions associated with the calibration areas when the first to-be-arranged views are projected to the calibration areas can be processed, and the projection image comprising only the naked eye 3D display screen image is determined from the original images.
S140, determining first correction quantity of any first pixel point in the display content to be corrected based on each projection image, and correcting the display content to be corrected in the calibration area based on each first correction quantity.
Specifically, the first pixel point may be a pixel point on the display content to be modified, and the screen resolution of the naked eye 3D display is assumed to be
Then 240000 first pixels are on the display content to be modified. The first correction amount may be a correction amount of the first pixel point determined by the scheme. The scheme can determine the first correction amount of any first pixel point in the display content to be corrected based on each projection image and is based onAnd each first correction quantity corrects the display content to be corrected in the calibration area.
For example, assume that the projected image has a resolution of
If the projected image has 20000 pixel points, taking the first pixel point in each projected image as an example, the scheme can determine the gray value of the first pixel point in each projected image, determine the maximum gray value from each gray value, further determine the projected image number corresponding to the maximum gray value, determine two adjacent projected image numbers adjacent to the projected image with the number, then determine the gray value of the first pixel point in the two adjacent projected images, and determine the correction amount associated with the first pixel point in each projected image according to the determined three gray values and the projected image number corresponding to the maximum gray value. By analogy, the scheme can determine the correction quantity matrix size through each projection image as
Suppose that the ratio of the screen resolution of the naked eye 3D display to the projected image is
That is, the correction amount associated with each pixel point in the projected image acts on the naked eye 3D display
A first pixel point within the region. Using bilinear interpolation method based on
The correction matrix determines the correction of each first pixel point in the display content to be corrected, namely the first correction. Determining the view number of the first pixel point after the correction according to the sum of the view number of the first pixel point on the display content to be corrected and the correction amount of the first pixel point, and determining the view number of the first pixel point after the correction according to the view number of the first pixel point after the correction and the correction amount of the first pixel pointAnd the first pixel point is correspondingly displayed relative to the naked eye 3D display screen.
According to the technical scheme provided by the embodiment of the invention, the display content to be corrected of the calibration area in the 3D display screen is determined; sequentially sending a first preset number of first to-be-arranged views to a calibration area for display; determining a projection image obtained at a corresponding position associated with the calibration area when each first view to be arranged is projected to the calibration area; and determining first correction amounts of any first pixel point in the display content to be corrected based on the projection images, and correcting the display content to be corrected in the calibration area based on the first correction amounts. By implementing the technical scheme provided by the embodiment of the invention, an ideal 3D display picture can be displayed for a user, crosstalk is avoided, the display defect of a naked eye 3D display before leaving a factory due to processing problems is overcome, and the 3D experience of the user can be improved.
Fig. 2 is a flowchart of a correction method for a naked eye 3D display screen according to an embodiment of the present invention, and the embodiment is optimized based on the foregoing embodiment. The same points can be referred to the above embodiments, and the embodiment is omitted here. As shown in fig. 2, the method for correcting a naked eye 3D display screen in the embodiment of the present invention may include:
and S210, determining the display content to be corrected in the marked area in the 3D display screen.
And S220, sequentially sending the first to-be-arranged views of a first preset number to the calibration area for displaying.
In this embodiment, optionally, the determining process of the first preset number of first to-be-ranked views includes: determining a second preset number of second views to be arranged; processing each second view to be arranged based on an interleaving algorithm to determine a first view to be arranged in a first preset number; the first preset number is larger than or equal to a second preset number.
The second preset number may be 8, the second preset number may also be 7, and the second preset number may be set according to actual needs. The first predetermined number needs to be greater than or equal to the second predetermined number. The second to-be-ranked view may be based on an interleaving calculationThe method may determine the first to-be-arranged views in the first preset number by processing each second to-be-arranged view, specifically, if the first preset number is 28 and the second preset number is 8, then the views in the first to-be-arranged views are numbered
With view numbers in the second to-be-ranked view
In a relationship of
. Wherein,
is a mixture of a water-soluble polymer and a water-soluble polymer, wherein the water-soluble polymer is 8,
is 28, assume that
A value of 16, then
And if the value is about 4.6, each pixel point in the first view to be arranged with the number of 16 is determined by performing weighted summation calculation by multiplying the pixel value of the pixel point in the second view to be arranged with the number of 4 by 0.6 and multiplying the pixel value of the pixel point in the second view to be arranged with the number of 5 by 0.4. It should be noted that other parameters of the display are fixed during the process of determining the first preset number of first to-be-arranged views.
Thereby, by determining a second preset number of second to-be-ranked views; and processing the second views to be arranged based on an interleaving algorithm to determine a first preset number of first views to be arranged, so that the correction result of the display content to be corrected can be more accurate, the display picture of the naked eye 3D display is more ideal, and the 3D use experience of the user can be improved.
And S230, determining a projection image obtained at the corresponding position associated with the calibration area when each first to-be-arranged view is projected to the calibration area.
In a possible embodiment, optionally, determining a projection image obtained at a corresponding position associated with a calibration area when each of the first to-be-arranged views is projected onto the calibration area includes: determining an original image obtained at a corresponding position associated with a calibration area when each first to-be-arranged view is projected to the calibration area; a projected image comprising only the naked eye 3D display screen image is determined from each of the original images.
In particular, the projection of the first to-be-arranged view acquired by the calibration camera onto the original image of the calibration area includes both the display content of the display and possibly other interfering content inside the darkroom, such as the light above the display. Therefore, the present solution requires determining a projected image including only the display content of the 3D display from each original image. The technique of determining the projection image from the original image may refer to the related art.
Thus, an original image obtained at the corresponding position associated with the calibration area when each first to-be-arranged view is projected to the calibration area is determined; a projected image comprising only the naked eye 3D display screen image is determined from each of the original images. It is possible to realize that a reliable data source is provided for the correction of the display content to be corrected.
S240, determining a first correction amount of any first pixel point in the display content to be corrected based on each projection image, and superposing the first correction amount of the first pixel point and the number of a second to-be-arranged view in which the first pixel point is located aiming at each first pixel point in the display content to be corrected, so as to correct the first pixel point.
Illustratively, assume a naked eye 3D display with a screen resolution of
Then 240000 first pixels are present in the display content to be modified. The scheme can adopt an interleaving algorithm to code the second to-be-ranked view to which each first pixel point belongs and the first image according to the to-be-ranked view to which each first pixel point belongs on the display content to be modifiedAnd determining the view number of the first pixel point after correction according to the sum of the correction amounts of the pixel points, and performing corresponding display on the first pixel point according to the view number of the first pixel point after correction and the relative position of the first pixel point relative to the naked eye 3D display screen, so that the display content of the pixel point is adjusted to other views, and further the correction of the display content to be corrected in the calibration area is completed.
In another possible embodiment, optionally, determining a first correction amount of any first pixel point in the display content to be corrected based on each of the projection images includes: determining the initial correction amount of any first pixel point in the display content to be corrected based on each projection image; and subtracting the initial correction of the pixel at the center point of the screen from the initial correction of the first pixel point in the display content to be corrected to obtain the first correction of the first pixel point.
According to the scheme, the initial correction amount of any first pixel point in the display content to be corrected can be determined based on each projection image, and the initial correction amount comprises the initial correction amount of a pixel at the center point of a screen, for example, 3. Then, the initial correction of a certain first pixel point in the display content to be corrected, for example, 5, is subtracted from the initial correction 3 of the pixel at the center point of the screen to obtain the correction 2 of the first pixel point, that is, the first correction.
Therefore, the initial correction amount of any first pixel point in the display content to be corrected is determined based on each projection image; and subtracting the initial correction of the pixel at the center point of the screen from the initial correction of the first pixel point in the display content to be corrected to obtain the first correction of the first pixel point. The display content to be corrected can be corrected, and the condition that the calibration result of the view correction amount is too large in spread range can be avoided.
In another possible embodiment, optionally, determining a first correction amount of any first pixel point in the display content to be corrected based on each of the projection images includes: determining the gray value of any second pixel point in each projection image; determining a first gray value, a second gray value and a third gray value of the second pixel point from all the gray values; the first gray value is determined by the maximum gray value in all the gray values; the second gray value and the third gray value are determined by adjacent projected images of the projected image determined according to the first gray value; determining a second correction quantity associated with the second pixel point according to the first gray value, the second gray value and the third gray value; determining the proportional relation between the resolution of the projected image and the resolution of the naked eye 3D display screen; and determining the first correction quantity of any first pixel point in the display content to be corrected according to the second correction quantities and the proportional relation.
For example, the second pixel point may be a pixel point in the projected image, assuming that the projected image has a resolution of
Then 20000 second pixels exist in the projected image. Taking the first second pixel point in each projection image as an example, the present solution may determine the gray value of the first second pixel point in each projection image, determine the maximum gray value from each gray value, then determine the projection image number corresponding to the maximum gray value, for example, 5, and determine the numbers of two adjacent projection images adjacent to the projection image with the number of 5, that is, the projection image 4 and the projection image 6. And then determining the gray value of a first second pixel point in two adjacent projection images, and determining correction quantity associated with the first second pixel point in each projection image, namely second correction quantity according to the determined three gray values and the projection image number 5 corresponding to the maximum gray value. By analogy, the number of the correction quantities determined by each projection image in the scheme is 20000, and the corresponding correction quantity matrix has the size
。
Suppose the proportional relationship between the screen resolution of a naked eye 3D display and the resolution of the projected image
That is, the correction amount associated with each second pixel point in the projected image acts on the naked eye 3D display
A first pixel point within the region. The scheme can adopt a bilinear interpolation method according to
The correction matrix determines a first correction of each first pixel point in the display content to be corrected. And determining the view number of the first pixel point after the correction according to the sum of the view number of the first pixel point on the display content to be corrected and the correction amount of the first pixel point, and performing corresponding display on the first pixel point according to the view number of the first pixel point after the correction and the relative position of the first pixel point to the naked eye 3D display screen.
Therefore, the correction matrix is determined through the projected images for each first pixel point in the display content to be corrected, the correction of each first pixel point in the display content to be corrected can be determined, and a reliable data source is provided for the correction of the display content to be corrected.
In this embodiment, optionally, determining a second correction amount associated with the second pixel according to the first gray scale value, the second gray scale value, and the third gray scale value includes: determining a second correction quantity of the pixel point based on the following formula:
wherein,
a second correction associated with the second pixel point is indicated,
a second gray-scale value is represented,
a first gray-scale value is represented,
a third gray-scale value is represented which,
indicating the number of the projected image determined by the first gray value.
For example, assuming that the number of the projection images is 28, for a certain second pixel point in each projection image, 28 gray values of the second pixel point can be obtained, wherein the maximum gray value is 200, that is, the first gray value. The second pixel point with the first gray value is located at the projection image serial number 1, the adjacent projection image serial number adjacent to the projection image with the serial number 1 is 28, and the gray value of the second pixel point in the projection image, i.e., the second gray value, is 195. The number of the other adjacent projection image adjacent to the projection image with the number 1 is 2, and the gray value of the second pixel point in the projection image, that is, the third gray value is 180. Namely, it is
The number of the carbon atoms is 1,
in the form of a number of 200,
is a number of 195, and is,
