Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Embodiments of the present application are further described below with reference to figures 1 through 4 of the specification.
FIG. 1 illustrates a schematic diagram of an exemplary operating environment 100 in which embodiments of the present application can be implemented. Referring to fig. 1, the operating environment 100 includes at least two projectors 110, a display control device 120 connected to the projectors 110, and an image acquisition device 130 acquiring a projection image. Wherein each projector 110 projects a partial projection image, and the partial display images projected by adjacent projectors 110 overlap in edge. The display control device 120 can control a part of the projection image projected by each projector 110, so that the part of the projection images projected by all the projectors 110 are spliced to form a whole projection image, thereby displaying a super-large, bright and high-resolution projection picture.
For convenience of description, the following description will be given by taking as an example an operating environment 100 including four projectors 110a, 110b, 110c, and 110 d.
Fig. 2 shows a schematic view of a stitching structure for stitching part of the projection images to form the whole projection image. In the operating environment 100, four projectors 110a, 110b, 110c, and 110d arranged clockwise each project a small square partial display image, and the four square partial display images are joined to form a large square whole display image, forming a fusion band ab, bc, cd, ad, and abcd of five projection images. The fusion zone ab, bc, cd and ad are formed by overlapping partial projection images projected by the two projectors, and the fusion zone abcd is formed by overlapping partial projection images transmitted by the four projectors.
If the effect image of the whole projection image is a picture projected by one projector, correcting the geometric positions of partial projection images by adopting a geometric correction technology so as to enable different partial projection images to be spliced naturally and continuously; the color correction technique and the edge blending technique are required to correct the image of the blend zone so as to avoid the blend zone highlight, i.e. color distortion, of the different parts of the projected image. In the present embodiment, only image correction of the fusion zone is considered without taking into account geometric correction of the partial projection image.
In the related art, a method for adjusting a fusion band is provided, in which all projectors 110 are first caused to project white, and a technician determines the brightness of the fusion band by naked eyes, and adjusts the brightness of a fusion band portion of each projector until the brightness of the fusion band is equal to the brightness of other portions, thereby completing adjustment of the fusion band. In the related art, the method for manually adjusting the fusion band has a large error, and only one color of the projected white is adjusted, and when the method is applied to the projector 110 with the non-linear output luminance component, the error of projecting other colors with an accurate adjustment result is still large.
Another adjustment method for the fusion band is provided in the related art, in which an attenuation curve of the projector 110 forming the fusion band is preset, the whole projection image is acquired by the image acquisition device 130, and the attenuation curve of the projector 110 is repeatedly adjusted according to an actual image of the fusion band in the whole projection image until the actual image matches the target image. Although the related art performs feedback adjustment according to various colors, the result of multiple feedback adjustment may not converge, and when the projection picture continuously changes, the result of one feedback adjustment is only suitable for adjustment of the previous frame of display picture, but not suitable for the next frame of display picture, and the display deviation of the fusion band may still be large and high frequency occurs during real-time playing.
In summary, in the related art, the two tuning modes cannot effectively overcome the problems of high brightness and color distortion of the fusion zone, and the projected whole projection image has a poor effect. In order to solve the problems in the related art, embodiments of the present application provide a method, an apparatus, and a system for adjusting a fusion zone based on image fusion.
Fig. 3 shows an exemplary flowchart of a method 300 for adjusting a fusion zone based on image fusion in an embodiment of the present application. The method 300 may be performed by the display control device 120 of fig. 1.
Step 310, a target display image of the display pixel points in the image fusion zone and corresponding projection pixel point information are obtained.
The target display image is an image which is required to be displayed by the display pixel point, and the target display image comprises display colors and display brightness.
Regarding the method for obtaining the projection pixel information corresponding to the display pixel, the position of the display pixel in the whole projection picture can be obtained first, and on the basis of the determination of the positions of the projectors 110, which projection pixels each display pixel corresponds to is determined. When the display control device 120 drives the projector 110 to project a partial projection image, the resolution of the projector 110 is determined, the projection pixel of the projector 110 is also determined accordingly, and the display pixel of the partial projection image and the display pixel of the entire projection image are also determined accordingly. In the image fusion zone, the display image of each display pixel point is formed by superposing and fusing the projection images of at least two appointed projection pixel points.
The above description may refer to fig. 2, where the display image of any one display pixel in the blend zone ab is formed by blending the projection images of two projection pixels from the projectors 110a and 110b, respectively, and the display image of any one display pixel in the blend zone abcd is formed by blending the projection images of four projection pixels from the projectors 110a, 110b, 110c, and 110d, respectively.
Therefore, for any display pixel point in the fusion zone, after the display pixel point is determined, the display image of the display pixel point is determined by overlapping and fusing the projection images of the appointed projection pixel points. The projection pixel point information corresponding to one display pixel point reflects that the display image of the display pixel point is formed by overlapping and fusing the projection images of which projection pixel points, the number of the projection pixel points is determined, and the designated position of which projector 110 each projection pixel point comes from is correspondingly determined.
And step 320, constructing an image fusion scheme according to the target display image and the projection pixel point information.
The image fusion scheme is a fusion scheme for fusing at least two single images into one fused image. The color of the fused image is the superimposed color of all the single image color lights in the image fusion scheme, and the brightness of the fused image is the sum of all the single image brightness in the image fusion scheme.
And acquiring a target display image of the display pixel point, wherein the target display image is the image required to be displayed by the display pixel point. Because the display image of the display pixel point is formed by superposing and fusing the projection images of the projection pixel points corresponding to the display pixel point, the projection images can be regarded as single images, and the target display image can be regarded as a fusion image. The projection pixel point information reflects the number of projection pixel points corresponding to the display pixel point, so that the final fused image of the image fusion scheme is determined and comprises a plurality of single image determinations, and the image fusion scheme can be constructed according to the color light fusion principle, so that the image fusion scheme is formed by superposing and fusing the number of single images to form the target display image.
It should be understood that the target display image is regarded as the fused image as a standard that the target display image and the fused image deviate less than a deviation set value, and specifically, both have a color deviation less than a color deviation set value and a luminance deviation less than a luminance deviation set value.
The constructed image fusion scheme may be included in a library of image fusion schemes. According to the image fusion scheme of the image fusion scheme library, along with the richness of target display images, the image fusion scheme in the image fusion scheme library is also richened, the fusion images comprise all possible target display images for displaying pixel points, different image fusion schemes exist for the same fusion images, and the image fusion schemes comprise that all possible single images in all possible quantities are fused into the fusion images.
In the method of the step, the basis for constructing the image fusion scheme is two: firstly, the color and brightness of the constructed fusion image of the image fusion scheme are consistent with those of a target display image, and the consistency can ensure that the color and the brightness are consistent and the color and brightness errors are within a preset error range; and secondly, the number of the single images of the constructed image fusion scheme is equal to the number of the projection pixel points corresponding to the display pixel points, so that the single images in the image fusion scheme can be projected by the projection pixel points corresponding to the display pixel points one by one.
And 330, configuring the projection pixel points corresponding to the display pixel points according to the image fusion scheme and the projection pixel point information.
The function of the method of this step is to determine the projected image projected by the projection pixel points.
Specifically, after an image fusion scheme is constructed for each display pixel point in the fusion zone, the number of single images in the image fusion scheme is equal to the number of projection pixel points corresponding to the display pixel point, so that it can be understood that the configuration process of this step is to match the single images to the corresponding projection pixel points one by one. Again, the images described herein are identical, meaning that the color and brightness of both images are the same.
After a group of projection pixel points corresponding to one display pixel point is configured, projection images projected by the group of projection pixel points can be fused to form a display image of the display pixel point.
And 340, under the configuration, adjusting the image fusion scheme according to the actual display image of the display pixel point and the target display image.
Before the method of this step, an obtaining step of an actual display image of a display pixel point is first included, and the obtaining of the actual display image of the display pixel point may be performed by the image obtaining device 130. The image acquiring device 130 may be an image acquiring device such as a camera, and the image acquiring device 130 may acquire the whole projection image by means of shooting, and correspondingly acquire the fusion zone image and the image of each display pixel point in the fusion zone.
Because the actual display image of the pixel point is configured and formed according to the constructed image fusion scheme, if the actual display image does not conform to the target display image, the constructed image fusion scheme has a deviation, and the display pixel point cannot display the target display image under the image fusion scheme, and at this time, the image fusion scheme needs to be adjusted.
The actual display image comprises actual colors and actual brightness, the target display image comprises target colors and target brightness, and if deviation occurs between the actual display image and the target display image, the deviation between the actual colors and the target colors and/or the deviation between the actual brightness and the target brightness are/is shown.
The method of this step needs to determine the specific deviation information of the actual display image and the target display image, and first needs to obtain the actual color and actual brightness of the actual display image and obtain the target color and target brightness of the target display image, so as to determine the specific deviation information in the following.
The deviation of the actual color and the target color and the deviation of the actual luminance and the target luminance may exist simultaneously or may exist only one.
When there is a color difference between the actual color and the target color, the color of the single image in the called image fusion scheme can be determined again, and this part of the content is mainly based on the color light fusion principle and is not described. In a word, the color superposition of a single image does not form a target color, which indicates that the construction error of the image fusion scheme occurs when the image fusion scheme library is constructed, and the image fusion scheme is reconstructed according to the calling result, so that the algorithm error in the stage of constructing the image fusion scheme in advance is eliminated, and the image fusion scheme in the image fusion scheme library is more accurate.
When there is a deviation between the actual brightness and the target brightness, the brightness of the single image in the called image fusion scheme may be adjusted, and if the actual brightness is higher than the target brightness designated value, the brightness of each single image in the image fusion scheme may be reduced by the ratio according to the ratio that the actual brightness is higher than the target brightness, or of course, the brightness of only a certain single image or a certain number of single images may be reduced, and only the brightness of the final fusion image may be reduced. The brightness superposition of the single image does not form the target brightness, which also indicates that the construction error of the image fusion scheme occurs when the image fusion scheme library is constructed, and the image fusion scheme with the construction error is adjusted, thereby being beneficial to the calibration of the image fusion scheme and the adjustment process of the fusion band.
It should be understood that the color and the brightness are both analog quantities that change continuously, and there are countless possibilities for the value of the analog quantity, but in the method 300 of the present embodiment, the size of the image fusion scheme library is obviously limited, so the method 300 of the present embodiment can be executed in a form of digitizing the color and the brightness in a differential manner, and the way of digitizing the analog quantity is not described herein. On the basis of digitization of both color and brightness, the image fusion schemes contained in the pre-constructed image fusion scheme library only contain all possible fusion schemes, but do not include the same fusion scheme.
In the method of this step, the adjusted image fusion scheme is stored in a new scheme, i.e. the adjusted image fusion scheme is stored in an "additional" manner, rather than in an alternative manner. However, after adjusting one image fusion scheme, the adjusted image fusion scheme may be the same as another image fusion scheme, and in this case, in order to keep the size of the image fusion scheme library smaller, part of the image fusion schemes may be deleted from the same image fusion scheme, so that the same image fusion scheme does not exist in the image fusion scheme library.
After the image fusion scheme is adjusted, the adjusted image fusion scheme is matched with the specified target display image, but the unadjusted image fusion scheme is not matched with the target display image, and at the moment, the color and the brightness of the fusion image can be redetermined by redetermining the color and the brightness of each single image in the adjusted image fusion scheme so as to determine the matched target display image.
According to the mode, the self-body size can be automatically maintained to be adaptive in the image fusion scheme library, the non-preset image fusion scheme can be added, the self content is enriched, and the self content can be enriched to avoid redundant information.
In addition, in the above content, there is a conversion process in which the actual display image is matched with the target display image, that is, when the target display image of the actual display image is determined, the acquired actual display image of another display pixel point may be used as the target display image of the display pixel point, the target display image of the another display pixel point is the same as the target display image of the display pixel point, and the another display pixel point is not in the image fusion zone. The construction and calling processes of the image fusion scheme can be carried out without conversion.
And 350, when the target display image of any display pixel point in the image fusion zone and the corresponding projection pixel point information are the same as the display pixel points, configuring the projection pixel point corresponding to the display pixel point according to the adjusted image fusion scheme.
The method 300 is embodied as a circular logic method, that is, the overall process of the method 300 is to construct an image fusion scheme when displaying pixel points in an image fusion zone, to call an existing fusion scheme when displaying pixel points that can be matched with the existing image fusion scheme, and to construct a new image fusion scheme according to the principle of the method when displaying pixel points that cannot be matched with the existing image fusion scheme.
In the method 300, when the display pixel needs to display the target display image, a corresponding image fusion scheme may be constructed, the corresponding projection pixel is configured according to the image fusion scheme, the actual display image of the display pixel is collected after the configuration is completed, and if the actual display image is deviated from the target display image, the constructed image fusion scheme may be adjusted. Therefore, the content of the image fusion scheme library is more abundant and accurate, the method can adapt to the accurate display requirements of various target display images, the adjustment result is more accurate than the attenuation mode, and finally each display pixel point in the image fusion zone can accurately display the target display image with the target color and the target brightness, the problems of high brightness, color distortion and the like of the fusion zone are effectively overcome, the whole display image is displayed by one projector, and the effect is excellent.
