In the step, by three reference axis of the first coordinate system acquired in step s101: the first reference axis, second
Reference axis and third reference axis correspond respectively to three different Color Channels in rgb space.It, can be in the step
Above-mentioned respective operations are can be completed into the color value that the value of one reference axis corresponds on a Color Channel.Optionally, by institute
The value for stating the first reference axis corresponds to the color value of the first Color Channel；The value of second reference axis is corresponded into the second color
The color value in channel；The value of the third reference axis is corresponded to the color value of third Color Channel.The first, second He herein
Third reference axis is simultaneously not specific to some reference axis, but any one in three reference axis, and first, second, and third is only
Distinguish these three reference axis；The first, second, and third Color Channel herein and be not specific in RGB triple channel some is logical
Road, but any one in three channels, first, second, and third only for distinguishing these three channels.It is specific at one
In example, using the value of X-axis as the channel the R color value in RGB color, using the value of Y-axis as the G in RGB color
Channel color value, using the value of Z axis as the channel the G color value in RGB color.In one embodiment, it can set in advance
The corresponding relationship between reference axis and Color Channel is set, when generating colour atla, according to the corresponding relationship by reference axis and color
Channel respectively corresponds, and details are not described herein.
Step S103: intermediate colour atla is generated according to the value of the first reference axis and the second reference axis；
In the step, the intermediate colour atla is only the colour atla comprising two kinds of color components or to have a kind of color component
It is fixed as 0 colour atla.It is described that intermediate colour atla packet is generated according to the value of the first reference axis and the second reference axis in the step
It includes: obtaining the first color value in the first reference axis and the second color value in the second reference axis；By first color value
The color value for two Color Channels being assigned in RGB color respectively with the second color value is to generate intermediate colour atla.It is optional
, the coordinate value of X-axis is obtained, the coordinate value of X-axis is assigned to the channel R in RGB color；The coordinate value for obtaining Y-axis, by Y
The coordinate value of axis is assigned to the channel G in RGB color, and channel B can be defaulted as 0 or be not provided with the value of channel B, in this way
Obtain the intermediate colour atla being located in the plane that X-axis and Y-axis form.Further, the obtained in the first reference axis
The second color value on one color value and the second reference axis may include: the model for obtaining the first color value in the first reference axis
Enclose the range with the second color value in the second reference axis.It is described to be assigned to first color value and the second color value respectively
The color value of two Color Channels in RGB color is to generate intermediate colour atla, comprising: in the range of the first color value and
The color value pair of the first color value and the second color value composition in all RGB colors is traversed in the range of second color value
To form the intermediate colour atla.Above-mentioned ergodic process is as follows: setting the first color value has N number of, and the second color value has M, wherein N
Integer with M is more than or equal to 0, takes 1 the first color value in N, traverses M the second color values later, forms M color value
It is right, M the second colors are all traversed to each of first color, ultimately generate N*M the first color values and the second color value
The color value pair of composition, this N*M color is to the formation intermediate colour atla.In the specific embodiment, the first face is obtained
The range of the range of color value and the second color value, such as integer of first color value between [0,255], the second color be also [0,
255] integer between sets 0 for the first color value first in this way, then all 256 in the second color traversal [0,255]
A integer obtains the color of 256 points, sets 1,2,3255 for the first color value later, executes respectively above-mentioned time
Step is gone through, the color of 256*256 point is obtained, using the result as intermediate colour atla.For 8 images, each of which
The color value in channel has 28=256 are worth, and generate standard color card under default situations, can traverse this for each Color Channel
256 values；And in some cases, in order to generate specific colour atla, the range of the value of adjustable Color Channel, the range
It can be arranged by mapping relations, such as X '=kX, wherein the value range of X default is [0,255], as K=0.2, X's '
Range is [0,51], it is possible thereby to adjust the color of Color Channel, and then the color for influencing entire colour atla is different from mark to generate
The specific colour atla of quasi- colour atla.Optionally, the range and the second reference axis of the first color value in the first reference axis of the acquisition
On the second color value range before, further includes: obtain the first colour atla configuration file, wrap in the first colour atla configuration file
Include the range of the first color value and the range of the second color.In the step, the first colour atla configuration file is to match in advance
It has been set that, the first colour atla configuration file can be located at network-side, be handed down to terminal device by the server of network-side, pass through
The first colour atla configuration file can configure the color of colour atla, form special colour atla used in image special effect.
It is understood that yes the value of the reference axis can be normalized value, and color value is normalized to [0,1] with table
Show same color, the normalization can obtain the color value divided by the maximum value of color value, specifically, when color value is
When integer between [0,255], color value 0 normalize after be 0/255=0, color value 5 normalize after be 5/255=0.0196,
And so on all color values and coordinate value can be normalized, so no matter color how many, can unify arrive using 0
1 coordinate value indicates.
Step S104: the sampled value of third reference axis is obtained；
The sampled value of the third coordinate, is the value of third coordinate, and the value determines the essence of finally formed colour atla
Degree.For 8 colour charts, the color value in each channel is 256, is come at this point for the colour chart of most thin precision
It says, 256 values of the sampled value between [0,255] for the scene for not needing high-precision colour atla, can be set in advance
Sampled value is set, the pre-set sampled value can be less than 256.
Optionally, as shown in Fig. 2, the step S104 may include:
Step S201: the sample rate of third reference axis is obtained；
Step S202: the sampled value is calculated according to the total and described sample rate of color value.
In step s 201, the sample rate is to be spaced the frequency of value, if sample rate is 4, then in third reference axis
Sampled value of the value as third reference axis is taken every 4 values.
In step S202, the quantity of sampled value is obtained divided by sample rate using the sum of color value, later according to sampling
Rate samples the quantity sampled value.Specifically, sample rate 4, then 256/4=64, then exist when the color value is 256
Sampled value 0,4,8,12252 is taken in third reference axis.
Optionally, before the step S201, further includes: obtain the second colour atla configuration file, second colour atla is matched
Set the sample rate in file including the third reference axis.In the step, the second colour atla configuration file is to match in advance
It has been set that, the second colour atla configuration file can be located at network-side, be handed down to terminal device by the server of network-side, pass through
The second colour atla configuration file can configure the color accuracy of a certain Color Channel of colour atla.It should be understood that institute
The the first colour atla configuration file stated in the second colour atla configuration file and step S103 of step can be the same configuration file,
I other words the configuration parameter of colour atla can once configuration be completed in the same colour atla configuration file, without using multiple match
Set file.
Optionally, the sampled value in step S104 can also specify directly in color value.Specifically, working as the color value
For the integer between 256, including [0,255], at this point it is possible to the sampled value of directly specified third reference axis is 0,10,100,
200,255.It should be understood that setting color value one shares n, n is the integer greater than 0, and sampled value can specify between [0, n]
Any number value, the same sampled value can also be configured by colour atla configuration file, and details are not described herein.
Step S105: the colour atla is generated based on the sampled value and the intermediate colour atla.
It is described to be based on the sampled value and the intermediate colour atla generation colour atla in the step, comprising:
The sampled value of the third reference axis is assigned in the intermediate colour atla color corresponding in third coordinate to lead to
Road is to generate multiple sub- colour atlas；The multiple sub- colour atla is arranged in order and generates the colour atla.
In above-mentioned steps, if sampled value is α, the α sampled value is distinguished to the third of intermediate colour atla described in assignment
The color value of Color Channel obtains α sub- colour atlas, and the α sub- colour atlas are arranged in order the generation colour atla.Such as Fig. 3
Shown, optionally, the value of X-axis represents the color value in the channel R in RBG color space, and Y-axis represents the color in the channel G in rgb space
Value, Z axis represent the color value of channel B in rgb space, and when 256 integer values of the color value between [0,255], sampled value is
When 0,4,8,12252 equal 64 values, the intermediate colour atla is successively moved according to sampled value on Z axis, obtains 64 sons
Colour atla, wherein 301 are equal to 0 sub- colour atla for Z axis value, 302 are equal to 4 sub- colour atla for Z axis value, and 303 are equal to 8 son for Z axis value
Colour atla, 304 are equal to 12 sub- colour atla for Z axis value, and 305 are equal to 252 sub- colour atla for Z axis value, and intermediate other sub- colour atlas do not show
Out.It is generated as shown in figure 4,64 sub- colour atlas are arranged according to the sequence of Z axis sampled value 0,4,8,12252 from small to large
