Abstract
The invention discloses a multi-display module image automatic registration method comprising the following steps, S1, an image multi-channel output module outputs images; S2, an image capture unit collects the multiple images output by the image multi-channel output module; S3, an image processing unit compares, processes and performs operation on the characteristic information of the multiple images collected to get a correction factor; and S4, the image processing unit adjusts an image input source according to the correction factor. The characteristic information of images, including position, shape, brightness and color, can be adjusted automatically through simple and fast system setting and processing, so that multiple images can be kept highly consistent in the whole display process.
Description
Technical field
The present invention relates to image display arts, more particularly to a kind of many display module automatic image registration methods.
Background technology
Existing image registration techniques generally comprise geometry registration, position registration, color registration and brightness registration.Match somebody with somebody
Manual adjustment is depended on quasi- method more.On the one hand skilled operator is needed, and will be devoted a tremendous amount of time, on the other hand
Enough precision can not be got.For example, polarization-type three-dimensional optical projection system is applied to, the Multiple-shower system possesses double light path
Optical texture, two light engines launch the image of different directions polarized light respectively, but due to light engine internal digital it is micro-
The difference of mirror device frame for movement, causes picture size and its position to be had any different, so that double light path optical projection system cannot be obtained
The anaglyph of accurate reproduction, as complete machine structure is limited, the adjustment of simple optics engine machine tool position is difficult this is completely eliminated
Plant difference.For the projector in consumer electronics market is applied to, excessive manual adjustment mode is also to be received
's.In addition in projection splicing, the application scenario that abnormity shows, image registration techniques can be also used.
The content of the invention
The present invention provides a kind of many display module automatic image registration methods, and such as Fig. 5 is comprised the following steps：
S1:Image multiple-channel output module output image；
S2:Image capturing unit gathers the multiway images of its output；
S3:The characteristic information of the multiple image for collecting is contrasted by graphics processing unit, is processed and computing, is drawn modifying factor
Son；
S4:Graphics processing unit is adjusted to image input source according to modifying factor.
Image multiple-channel output module output image can export at least two width images simultaneously.And output image has big
Little, position, one or more in the feature such as brightness and color coexist.
The image information that image capturing unit is obtained includes the size of image, position, in the feature such as brightness and color
One or more.
Graphics processing unit can receive the multiple image information of image capturing unit transmission, and by the spy of multiple image
Reference breath is contrasted, and is processed and computing, is drawn modifying factor.Draw one group or multigroup corrected parameter.
Graphics processing unit can send a command to image multiple output function module according to corrected parameter, to output image
One or more carried out in the features such as size, position, brightness and color make a change.
By more than, simple efficiently system arranges and processes the characteristic information of energy adjust automatically image, makes multiple image exist
Keep highly consistent during whole display.
Description of the drawings：
The inconsistent schematic diagram in picture position that many display modules of Fig. 1 occur；
Fig. 2 is used for the characteristic image for determining image information；
Fig. 3 is not corrected the input and output image of front many display modules；
Fig. 4 be corrected after many display modules input and output image；
A kind of many display module automatic image registration method and steps of Fig. 5.
Specific embodiment：
In order to be more clearly understood to the technical characteristic and effect of the present invention, the tool that accompanying drawing describes the present invention in detail is now compareed
Body mode.
Two projecting optical engines are placed up and down side by side, export the same characteristic image with distinctive mark respectively, because
For two engine optics and the difference of mounting structure, the picture position of output and shape also produce difference, such as accompanying drawing 1.With spy
The image for levying mark is as shown in Figure 2.
Photographic head acquisition characteristics image information with image capturing functionality.
Graphics processing unit draws the size and information of image by the analysis of coordinate of corner in characteristic image, respectively
The position of feature pattern in the image that the feature pattern position and photographic head for going out each light engine original input signal captures
Between relation.
Graphics processing unit is adjusted to the input image information of two light engines of optical projection system according to corresponding relation
It is whole.
For misaligned image, corresponding scaling process is carried out by the positional information that photographic head is captured to image,
The algorithm used during scaling is linear difference algorithm.
Fig. 3 is the input and output image for not carrying out many display modules before automatic aligning, and Fig. 4 is many after carrying out automatic aligning
The input and output image of display module.
Above be one embodiment of the present of invention, be familiar with skilled artisan the present invention design under done by
Equivalent derivative schemes belong to the present invention it is protected in the range of.
