Or 36 chromatic graph card as reference object.
Step S102：The second image that the camera shoots the test pattern in set scene is obtained, described in acquisition
Second color value of the second image corresponding pixel points；
In this step, in order to ensure the first obtained color value is more representative, common 24 chromatic graph card can be selected
Or 36 chromatic graph card as reference object.It should be noted that in the specific implementation, in order to ensure the camera imaging of the present invention
The accuracy of color adjustment method, step S102 and step S101 must use same test pattern.Setting described in this step
It includes but not limited to solar irradiation scene, colourama according to scene etc. to determine scene.
Step S103：It is poor to first color value and the second color value make, and obtains the face of image corresponding pixel points
Value of chromatism；
In this step, it according to the color difference of obtained image corresponding pixel points, can obtain shooting under lamp box
Color error ratio between image and the image shot under set scene.
Step S104：The parameter adjustment value that camera imaging color is calculated according to the color difference, according to the parameter
Adjusted value is adjusted the imaged color parameter of camera.
Above-mentioned camera imaging color adjustment method, by obtain the test pattern that camera is shot under lamp box first
Image obtains the first color value of described first image corresponding pixel points；By obtaining the test chart shot under set scene
Second image of card obtains the second color value of the second image corresponding pixel points；To first color value and the second face
It is poor that color value make, and obtains the color difference of image corresponding pixel points；Camera imaging color is calculated according to the color difference
Parameter adjustment value, the imaged color parameter of camera is adjusted according to the parameter adjustment value.Pass through above-mentioned technical side
Case adjusts the imaged color of camera, effectively improves the imaging effect of camera.
Above-described embodiment is fused to by the color value for the image corresponding pixel points that will be shot under set scene in lamp box
In the color value of lower shooting image, the color between the image shot under lamp box and the image shot under set scene is had adjusted
Color deviation effectively improves the actual imaging effect of camera, i.e., actual effect seen by person so that be adjusted imaging
The image that camera after color is shot is closer to true imaging.
As shown in Fig. 2, Fig. 2 is the camera imaging color adjustment method flow chart of an alternative embodiment of the invention,
In the present embodiment, after described the step of being adjusted to the imaged color parameter of camera according to the parameter adjustment value,
Can also include：
Step S105：It obtains the camera after adjustment and shoots the third image of the test pattern under lamp box, and by institute
It states third image and the second image is shown on standard indicator；Judge the third image and second image at
As whether color is consistent；

Show influence of the deviation existing for device to camera actual imaging effect
If cycle adjustment module 106 obtains the third color of the third image corresponding pixel points for inconsistent
Value, and to the third color value and the second color value carry out make it is poor, obtain the first color difference of image corresponding pixel points；Root
According to first color difference, the first parameter adjustment value of camera imaging color is calculated, according to first parameter adjustment value
The imaged color parameter of camera is adjusted, the camera after adjustment shoots the figure of the test pattern under lamp box
As consistent with the imaged color of the second image.
In cycle adjusts module 106, if the imaged color of the third image and second image is inconsistent, need
Continue to carry out cycle adjustment to the imaged color parameter of camera, the camera after adjustment shoots the survey under lamp box
Attempt card image it is consistent with the imaged color of the second image until.
In practical applications, specific camera imaging color parameter method of adjustment can select according to actual needs, this
Using poor method is made in embodiment, other methods can also be used, for example, first, first color value is added or
The half for subtracting the color difference obtains the first adjustment color value；According to the first adjustment color value calculate camera at
As the first parameter adjustment value of color, the imaged color parameter of camera is adjusted according to first parameter adjustment value；
The camera after adjustment is obtained again and shoots the 4th image of the test pattern under lamp box, and by the 4th image and the
Two images are shown on standard indicator；Judge the 4th image and second image imaged color whether one
It causes.If also inconsistent, continue a quarter ... for adding or subtracting the color difference in the first adjustment color value
And so on, the camera after adjustment shoots the imaging of the image and second image of the test pattern under lamp box
Until color is consistent.Certainly, in adjusting module 104, the method that directly citing can also be used described, to camera at
As color parameter is adjusted.
Camera imaging color of the invention adjusts system in one of the embodiments,：First color value is the
The color value of tri- kinds of primary colours of R, G, B of one image corresponding pixel points, second color value are the second image corresponding pixel points
R, the color value of tri- kinds of primary colours of G, B.
