Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of grating, in particular to a multi-view grating image synthesis method with a perspective position. BACKGROUND
[0002] Gratings are used to convert continuous tone images, such as photographs, gradations of color, etc., into halftones that can be reproduced by a printing press. The principle is based on the visual mixing effect of the human eye - when halftones of different sizes or densities are arranged in a certain pattern, the observer will visually perceive a smooth color transition. Generally, gratings can allow viewers to see different images at different positions under the grating at different angles when changing the viewing angle. However, the functions of the synthesized gratings are too single at present, and cannot adapt to scenes with changing needs. SUMMARY
[0003] In order to solve the problems existing in the prior art, the present application provides a multi-view grating image synthesis method with a perspective position, which adds a perspective function after grating synthesis, so as to adapt to scenes with changing needs.
[0004] The present application provides a multi-view grating image synthesis method with a perspective position, comprising:
[0005] At least one group of non-perspective gratings is set, and at least one perspective grating is synthesized between adjacent two non-perspective gratings;
[0006] Patterns are set in the non-perspective gratings, and the patterns are composed of multiple groups of static shapes;
[0007] A view area is set behind the perspective grating.
[0008] Preferably, the multi-view grating image synthesis method with a perspective position provided by the present application comprises:
[0009] The image of the non-perspective grating is padded with white ink under the color part of the image when printing.
[0010] Preferably, the multi-view grating image synthesis method with a perspective position provided by the present application is padded with black ink under the white ink.
[0011] Preferably, the multi-view grating image synthesis method with a perspective position provided by the present application comprises:
[0012] Two groups of non-perspective gratings are set, and one perspective grating is synthesized between adjacent two non-perspective gratings of each group.

[0017] In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0018] It should be noted that, in this document, the relationship terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. In this document, the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of another identical element in the process, method, article or device including the element.
[0019] In the prior art, the function after grating synthesis is too single, and cannot adapt to scenes with changing requirements. The embodiments of the present application provide the following solutions:
[0020] As Figure 1As shown, this embodiment provides a method for synthesizing a multi-view grating image with perspective, the method comprising the following steps:
[0021] Step 1: setting at least one set of non-perspective gratings, and synthesizing at least one perspective grating between two adjacent non-perspective gratings.
[0022] Step 2: Setting a pattern in the opaque grating, wherein the pattern is composed of a combination of multiple groups of static shapes.
[0023] In some embodiments, when printing an image without a see-through grating, white ink is placed under the colored portion of the image to ensure the accuracy of color reproduction.
[0024] In some embodiments, black ink is placed under the white ink to make it more distinct from the perspective portion, thereby achieving a better effect and reducing the influence of backlight on the image.
[0025] Step 3: Setting a viewing area behind the perspective grating. It should be noted that the viewing area can be placed with a suitable image according to the actual scene requirements, and the image can also be a real scene.
[0026] In some embodiments, as Figure 2 As shown, a group of non-perspective gratings is set, and two adjacent non-perspective gratings in each group are combined into a perspective grating.
[0027] It should be noted that when the viewing angle is changed, the image "A" of the grating is displayed at viewing angle A, while at viewing angle B, the line of sight will see the image or real scene behind the grating through the perspective grating. The perspective grating is the transparent position.
[0028] For example, consider two images, "A" and "B." Image "B" is empty. The images are then split equally according to the grating line widths and synthesized into new files, A1+B1, A2+B2, ...An+Bn. The width of these new files is Aw+Bw, and the width of these new files is compressed to the original image width, w. The compressed images are printed on the reverse side of the grating material. The white padding at position "A" needs to be thick enough to prevent it from being seen through, while the white padding at position "B" must not be thick enough. At this point, when the viewer is viewing the image from the front of the grating, they can change their viewing angles. At view A, they can see image "A," and at view B, they can see image "B," i.e., transparent.
[0029] For example, by utilizing the above-mentioned technical features, the product name, introduction, pattern and other product information can be clearly seen from the outside of the packaging box at viewing angle A, and the contents of the packaging box can be seen from viewing angle B.
[0030] Similarly, two groups of non-perspective gratings are set, and two adjacent non-perspective gratings in each group are combined into a perspective grating.
[0031] For example, the scenic spot creative products developed by using the above technical features, the main picture can generally show the scenic spot characteristic scenery photos or reflect the local characteristics of the pattern, and the inside of the sleeve is printed with other characteristic pictures or words of the scenic spot. When the photo is not put into the sleeve, the observer can see the images A and B by changing the viewing angle, when the photo C is put into the sleeve, the observer sees A and C. The back of the sleeve can usually be the text introduction of the history, culture, allusion and the like of the scenic spot.
[0032] Furthermore, the present application is also suitable for multi-picture schemes of more than two variable images and partial perspective variable picture schemes in the picture. The present application also covers the application of partial variable perspective in the production of lenticular pictures.
[0033] In some embodiments, in the lenticular picture of two variable images, the printed image is set to 1 / 2N width of each line, and the transparent part is also 1 / 2N width. Similarly, for the lenticular picture of three variable images, 2 images each occupy 1 / 3N width of each line, and the transparent part is also 1 / 3N width. N can be set to 1 to 200 lines.
[0034] In summary, the embodiments of the present application provide a multi-view lenticular image synthesis method with a perspective position. The lenticular synthesis adds a perspective function, and different images can be set according to the application scene behind the perspective lenticular, so as to adapt to scenes with changing needs and expand the function.
[0035] The above merely provides specific embodiments of the present application, and the protection scope of the present application is not limited thereto. Those skilled in the art can make changes or substitutions within the technical range disclosed in the present application, and these changes or substitutions shall be within the protection scope of the present application.
[0036] Those skilled in the art can understand that although some embodiments described herein include certain features but not others included in other embodiments, the combination of features of different embodiments means to be within the scope of the present application and form different embodiments.
[0037] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes shall fall within the scope defined by the appended claims.
