The high-definition picture processing method includes second step S2: by a frame original image to be processed be divided by
Number multiple subgraphs of arrangement.
In embodiment, the subgraph obtained after segmentation can import rendering platform to create and draw texture resource, in order to
Rendering platform is facilitated to be handled, in step S2, the resolution ratio of multiple subgraphs after segmentation is no more than image rendering and is supported
Single texture out to out.Specifically, the resolution width for the single texture out to out that can be supported rendering platform is remembered
For w_max, the value that resolution height is denoted as h_max, w_max and h_max can be obtained according to the software parameter of rendering platform,
In a kind of rendering platform, w_max and h_max are 8192.In the case where meeting no more than the restriction of texture out to out, implement

Such as, the resolution width of standard texture scale is denoted as w, resolution height is denoted as h, wherein [0, w_max] w ∈, h ∈ [0, h_
max]。
Specifically, a step of frame original image is divided into the multiple subgraphs arranged by number may include: first
Sub-step sets a standard texture scale, and the resolution ratio of the standard texture scale is w*h, and w is lateral resolution, and h is longitudinal
Resolution ratio, the standard texture scale are no more than the single texture out to out that image rendering is supported；Second sub-step, respectively
H/h and W/w is calculated, the integer part of calculated result is taken, adds 1 on the basis of the integer part if any fractional part, thus
The original image is divided into multiple subgraphs of m row n column distribution.Thus in the multiple subgraph, described at least one
The resolution ratio of subgraph is the horizontal and vertical resolution ratio that w*h, W and H are respectively original image, and m and n are integer and at least one
It is a to be greater than 1.
Fig. 2 is the schematic diagram after the high-definition picture processing method segmentation original image using one embodiment of the invention.
Referring to Fig. 2, when a frame original image is divided into the subgraph of m row n column, m and n meet m=H/h+1, n=W/w+1, wherein H/
H and W/w indicates rounded division, and remainder is as a line (or column) after adding 1 expression to be divided by.Subgraph after segmentation can according to from
The ranks sequence of top to bottm from left to right is numbered, and the number of the subgraph of the i-th row jth column can be denoted as (i, j), by the i-th row
The resolution ratio of the subgraph of jth column is denoted as f (i, j), wherein i ∈ { 1,2 ..., m }, j ∈ { 1,2 ..., n }.
Utilize the above method, through over-segmentation, the subgraph of most available four kinds of resolution ratio: point of the first drawing of seeds picture
Resolution is w*h, and Serial Number Range is i ∈ { 1,2 ..., m-1 }, j ∈ { 1,2 ..., n-1 }；The resolution ratio of second seed image is
(W- (n-1) × w) * h, Serial Number Range are i ∈ { 1,2 ..., m-1 }, j=n；The resolution ratio of third drawing of seeds picture is w* (H- (m-
1) × h), Serial Number Range i=m, j ∈ { 1,2 ..., n-1 }；The resolution ratio of 4th drawing of seeds picture is (W- (n-1) × w) * (H-
(m-1) × h), number i=m, j=n.As an example, take W=100, H=100, w=9, h=8, then m=100/8+1=
13, n=100/9+1=12, through over-segmentation, subgraph that available 12*11 resolution ratio is 9*8,12*1 resolution ratio are
The subgraph and 1*1 resolution ratio that the subgraph of 8* (100-11*9), 1*11 resolution ratio are (100-12*8) * 9 are (100-
12*8) the subgraph of * (100-11*9).
The high-definition picture processing method includes third step S3: creating multiple texture cells, each texture
Unit is corresponded with each subgraph and resolution ratio is identical.

Number corresponding with the number of subgraph, i.e., subgraph (i, j) is corresponding texture cell (i, j).The resolution ratio of each texture cell is arranged
For the resolution ratio f (i, j) equal to identical number subgraph.Texture cell created can be loaded into video memory and store.
The high-definition picture processing method includes four steps S4: set the size of output picture, and create with it is each
A one-to-one flat unit of the texture cell, area summation and the output picture of all flat units
Area equation, and the area of each flat unit is directly proportional to the pixel number of corresponding texture cell.
The image that will the be exported i.e. width of output picture is denoted as size_W, and the height of output picture is denoted as size_H,
Size_w (i, j) is the width of flat unit corresponding with the texture cell that the i-th row jth arranges, and size_h (i, j) is and the i-th row
(width and height here is non-for referring to resolution width and height for the height of the corresponding flat unit of texture cell of jth column
Degree, and refer to the width and height of Physimetric), then, according to horizontal and vertical point of corresponding texture cell (or subgraph)
The size of ratio and output picture of the resolution in the resolution ratio of original image, can calculate the ruler of each flat unit
It is very little.In specific embodiment, the size of the output picture, the size of the flat unit and corresponding with the flat unit

The center of face unit is overlapped with the center of output picture, is denoted as P (i, j)=O, in addition sets the original image
Image origin pixel, described image origin pixel are located at the top left corner apex position of the subgraph of the first row first row；
Then, the inclined of the central point pixel distance described image origin of the corresponding subgraph of each texture cell is calculated
It moves, for example, the offset of the image origin pixel of the central point pixel distance original image of subgraph (i, j) is denoted as g (i, j),
Referring to Figures 1 and 2, g (i, j) meet following relational expression (show the situation of the subgraph of four kinds of resolution ratio, wherein H%h and
W%w indicates that analog value is divided exactly and taken the remainder):
To can get original image described in the central point pixel distance of the corresponding subgraph of each texture cell
The offset of central point pixel is g (i, j)-(W/2, H/2)；
Then, the aspect ratio for keeping the original image makes in every group of corresponding flat unit and texture cell, described flat
Central point pixel of the face unit relative to the offset subgraph corresponding with the texture cell at the center of the output picture
Shift ratio it is identical, to obtain each flat unit according to the offset at the center relative to the output picture
Position.
In order to keep the aspect ratio of original image, pixel-shift ratio should be identical as physical deflection ratio, therefore can obtain
Wherein, Offset (i, j) is represented with texture cell (i, j) corresponding flat unit relative to output picture center
Offset, subscript x and y are illustrated respectively in coordinate system insied width direction and the component of short transverse of image physical size, subscript u
The component of the width direction and short transverse in pixel coordinate system is illustrated respectively in v.
Obtain Offset (i, j) after, with texture cell (i, j) position of corresponding flat unit can be expressed as P (i,
J)=O-Offset (i, j).To pass through the offset of Calculation Plane unit center position, plane cell location is had updated with weight
