Description
Technical field
The present invention relates to the method for image mosaic fusion, more particularly to a kind of panorama backing system colour-balance adjustment side
Method.
Background technology
The four-way CCD camera of panorama backing system is under the changeable light in garage parking, or different cars are being received around night
During the light-illuminating of lamp, the color white balance of four-way CCD camera can be different, cause splicing regions transition portion image to occur obvious
Aberration, display effect is poor, if color transition can not be adjusted before presentation to a user, make splicing regions transition from
So, the experience effect of user will be reduced, and user easily ignores the abnormal object occurred in image, causes reversing to occur asking
Topic.
The content of the invention
It is a primary object of the present invention to provide a kind of panorama backing system color balance adjusting method, it is intended to which multichannel is taken the photograph
As the splicing regions of head carry out over-colored treatment, balance over-colored.

Color R, G, B accounting is weighted averagely, obtains R, G, B weight in the road video-splicing region.
Preferably, by R, G, B weight, the R of each splicing regions, G, B component and and each splicing regions scope, obtain
R, G, B gain of each splicing regions of road video.
Preferably, in step S02, gain is compared with default regulation threshold values, judges whether to need to adjust image
It is trichromatic to concretely comprise the following steps：
The yield value and default regulation threshold values of R, G, B are contrasted, when the yield value of one of component is less than regulation threshold values
When, then the aberration of splicing regions is normal, otherwise the aberration exception of splicing regions；
When the aberration of splicing regions is abnormal, then according to the color of each R, G, B gain-adjusted splicing regions；
When the aberration of splicing regions is normal, then splicing regions scope is reduced by default stepping, as stated above again
The aberration of splicing regions is judged, until the color or the splicing regions that adjust the splicing regions are reduced into zero.
Panorama backing system of the present invention is analyzed after multiway images are collected by the comparison to abnormal chromatism data, mark
The transitional region of the abnormal aberration in panoramic mosaic region is made, the mistake of the yield value to abnormal aberration of statistical precipitation is reused
Cross region to be adjusted, ultimately form the uniform view data of color transition.
