How to make 3D photos

technical field

The invention relates to a three-dimensional imaging method, in particular to a method for making a three-dimensional photo.

Background technique

At present, there are usually two ways to obtain 3D photos. One method is to use a 3D camera to directly shoot the synthesized image, and then use a proprietary printing device to print a 3D photo that can be displayed in 3D; the other method is to use image processing technology to combine the two 3D photos are synthesized into 3D photos for 3D display. In the first method, 3D photography includes optical components with complex structures, so the cost is relatively high; in addition, because of the need to use proprietary printing equipment, it is not only troublesome but also expensive, so the use of 3D cameras is not widely promoted now.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The method for making a three-dimensional photo according to an embodiment of the present invention includes making a three-dimensional image; developing the three-dimensional image into a photo; and matching the printed photo with a grating plate to form a three-dimensional photo. Among them, the grating plate used is various slit gratings or lenticular lens gratings available on the market. The following discussion will take the slit grating as an example; in addition, the size of the selected grating plate is equal to the size of the printed photo.

As shown in Figure 1, specifically, the above-mentioned production of a three-dimensional image includes step S100. In step S100, the same subject is first photographed simultaneously from multiple angles to obtain multiple photographs P ₁ , P ₂ , ..., P with parallax information. _n (n is greater than 1), if it is taken by a digital camera, the digital file of the photo can be directly extracted for backup; if the photo is printed on film, the digital file of the photo can be obtained by scanning for backup . In addition, taking pictures can be, for example, two images taken simultaneously from a dual-lens camera, which are similar to two images with parallax information viewed from the left and right eyes; or, for example, using multiple cameras from multiple Stereoscopic shots of the same subject at the same time, resulting in more than two photoshoots.

The above-mentioned making of a three-dimensional image further includes step S200. In step S200, a blank image is firstly generated, and the blank image is a blank image file in a digital format. Then the blank image is divided in parallel at equal intervals to obtain a plurality of blank bars T ₁ , T _{2 ,} . The above segmentation is to divide the blank image into multiple regions.

The above-mentioned production of a three-dimensional image also includes step S300. In step S300, multiple photographs are sequentially stacked in each blank chart to form the above-mentioned three-dimensional image. The stacking mentioned here refers to digital files in digital image processing Format for overlapping placement of images. The stacking order is not limited, for example, the order of P ₁ , P ₂ , . . . , P _n may be adopted, or any other order. The three-dimensional image obtained in this step is developed into a photo and then matched with a grating plate to form a three-dimensional photo that can be directly viewed by human eyes.

first embodiment

In the first embodiment of the present invention, in order to make the image viewed from the grating plate more delicate and soft, step S211 is further included after dividing the blank image in step S200 to obtain a plurality of blank graph strips. The above blank bars can be used to obtain multiple sub-blank bars, as shown in Figure 2, after the blank bar T _i (1≤i≤m) is equally spaced, five sub-blank bars T _i1 , T _i2 , ..., T _i5 are obtained . Of course, there can also be 2, 3, 8 and so on. And in step 300, a plurality of photographs P ₁ , P _{2 ,} . Theoretically, if there are more divided sub-blank bars _and more sub-blank bars where the photographs P ₁ , P ₂ , . Preferably, each of the above-mentioned blank charts is divided in parallel at equal intervals to obtain multiple sub-blank charts in each blank chart, and multiple photographs P ₁ , P ₂ , ..., P _n .

second embodiment

In the second embodiment of the present invention, in order to make the image viewed from the grating plate more delicate and soft, step S212 is further included after dividing the blank image in step S200 to obtain a plurality of blank graph strips. The above-mentioned blank graph bar obtains a plurality of sub-blank graph bars, but the multiple sub-blank graph bars are an odd number, such as 3, 5, 7 and so on. Specifically, 2k+1 sub-blank bars T _i1 , ..., T _i(k+1) , ..., T _i(2k+1) are obtained after dividing the blank bar T _i (1≤i≤m) at equal intervals . And in step 300, a plurality _of photographs P ₁ , P _{2 ,} . At the same time, place a photograph (such as P ₁ ) of the bottommost layer of multiple photographs P ₁ , P ₂ , ..., _Pn stacked in sequence on at least one sub-blank diagram on one side of the central sub-blank bar In the bar (for example, at least one of T _i1 to T _ik ); place a topmost photo (for example, P _n ) of a plurality of sequentially stacked photos P ₁ , P ₂ , ..., P _n in the center sub-section In at least one sub-blank bar (for example, at least one of T _i(k+2) to T _i(2k+1) ) on the other side of the blank bar. Preferably, each of the above-mentioned blank graph bars is divided in parallel at equal intervals to obtain multiple sub-blank graph bars in each blank graph bar. The photo is placed in each sub-blank bar on one side of the central sub-blank bar; the topmost photo of the sequentially stacked multiple photo-shoots is placed in each sub-blank bar on the other side of the central sub-blank bar within the article.

Specifically as shown in FIG. 3 , in step S212 , five sub-blank bars T _i1 , T _i2 , T _i3 , T _i4 , and T _i5 are obtained after dividing the blank bar T _i (1≤i≤m) in parallel at equal intervals. In step 300, a plurality of photographs _{P 1} , P _{2 ,} . At the same time, a bottom-most shot (for example, P ₁ ) of the sequentially stacked multiple shot photos P ₁ , P ₂ , ..., P _n is placed in at least one of T _i1 and T _i2 , or at the same time Placed in T _i1 and T _i2 ; place the topmost photo (for example, P _n ) of multiple stacked photos P ₁ , P ₂ , ..., P _n in at least one of T _i4 and T _i5 One, or both T _i4 and T _i5 . The purpose of this setting is to compensate for the sequentially stacked multiple shots in the central sub-blank with the images in the sub-blanks on both sides of the central sub-blank, for example through the images in T _i1 and/or T _i2 P ₁ and _a plurality of _sequentially stacked photographs _{P 1 , P 2} , . _. . Therefore, the finally obtained stereoscopic display is not only soft, but also has a better three-dimensional effect. If there are more divided sub-blanks and more sub-blanks where photographs are placed, the stereoscopic image displayed by the grating plate will be more delicate and soft, and the three-dimensional effect will be better.

As can be seen from the above, by adopting the method for making a three-dimensional photo according to the present invention, existing two-dimensional pictures or images can be synthesized into a three-dimensional image that can be displayed stereoscopically. Can be displayed as a 3D photo. Then, by further optimizing the synthesized image, the stereoscopic display of the image is more delicate and soft, and the stereoscopic display effect is enhanced.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present invention.
