Therefore, the processing method of the plane picture in the prior art cannot effectively display the plane picture, and the fidelity of the three-dimensional display is to be improved.

In this embodiment, a method for processing a planar picture is provided first, which overcomes, at least to some extent, the defect that the fidelity of the planar picture processed by the prior art needs to be improved.

Fig. 1 schematically illustrates a flowchart of a method for processing a flat picture according to an embodiment of the present invention, and an execution subject of the method for processing a flat picture may be a server for processing a flat picture.

Referring to fig. 1, a method of processing a flat picture according to an embodiment of the present invention includes the steps of:

step S101, cutting a two-dimensional model according to the outline of the two-dimensional model in a plane picture to obtain a silhouette picture;

step S102, according to the line spacing of the two-dimensional model in the silhouette picture, obtaining parameters for carrying out three-dimensional treatment on the two-dimensional model so as to draw based on the parameters, and obtaining a three-dimensional model;

and step S103, carrying out projection removing processing on the three-dimensional model to obtain a picture to be displayed so as to finish the three-dimensional display of the plane picture.

In the technical scheme provided by the embodiment shown in fig. 1, on one hand, a two-dimensional model is sheared according to the outline of the two-dimensional model in a plane picture to obtain a silhouette picture, so that the silhouette picture is generated according to the two-dimensional model and is closer to the two-dimensional model, and the gap between the three-dimensional model and the two-dimensional model after three-dimensional treatment is reduced; furthermore, according to the line spacing of the two-dimensional model in the silhouette picture, parameters for carrying out three-dimensional treatment on the two-dimensional model are obtained, and drawing is carried out based on the parameters to obtain a three-dimensional model, so that visual angle lasting possibly caused after three-dimensional treatment of the two-dimensional model can be avoided, and the drawing accuracy of the three-dimensional model can be improved; on the other hand, the picture to be displayed is obtained by carrying out projection removing processing on the three-dimensional model so as to finish the three-dimensional display of the plane picture, so that the two-dimensional model in the picture to be displayed has a three-dimensional effect, the picture to be displayed is also the plane picture, the plane attribute, the modeling sense and the picture mood of the plane picture are reserved, and the fidelity of the three-dimensional display of the plane picture is improved.

The specific implementation of each step in fig. 1 is described in detail below:

in step S101, the two-dimensional model is cut according to the contour of the two-dimensional model in the planar picture, so as to obtain a silhouette picture.

In an exemplary embodiment, the planar picture may be a two-dimensional picture such as an ancient painting, a photograph, or the like; a two-dimensional model in a planar picture, i.e., a character in a picture (e.g., mountain, character, animal, etc.); the outline of the two-dimensional model in the plane picture is the composition line of the drawn character (such as the line of the mountain drawn in the ancient painting); the silhouette picture represents only the outline of a two-dimensional model, namely, only the outline shapes of people, buildings, mountains, trees and the like in the picture are represented, and the detailed schlieren level of the silhouette picture is not represented, which is similar to a character image cut by scissors.

In an exemplary embodiment, referring to the above example, in 3Ds MAX software, a two-dimensional model in an ancient painting or other painting may be selected to perform outline clipping to obtain a silhouette picture. Wherein, for the same plane picture, the shearing angle is fixed. By way of example, the shearing angle may be set to 30 degrees in top view. Of course, according to actual needs, other angles can be set as the shearing angles, which all belong to the protection scope of the invention.

In an exemplary embodiment, the planar image includes a plurality of two-dimensional models (for example, M are positive integers), so that the M two-dimensional models need to be cut according to line outlines of the M two-dimensional models in the planar image, so as to obtain corresponding M silhouette images. The outer contour shearing is carried out on the M two-dimensional models in the plane picture by adopting the same shearing angle, so that M sheared shadow pictures obtained after shearing are obtained under the same visual angle, and the method is beneficial to improving the fidelity of the picture display of the processed picture.

In step S102, according to the line spacing of the two-dimensional model in the silhouette image, parameters for stereoscopically implementing the two-dimensional model are obtained, so as to draw based on the parameters, and a three-dimensional model is obtained.

In an exemplary embodiment, fig. 2 schematically shows a flowchart of a method for processing a planar picture according to another embodiment of the present invention, and specifically shows a flowchart for obtaining a three-dimensional model from a silhouette picture.

Referring to fig. 2, the method provided by this embodiment includes step S201 to step S203, and step S102 is explained below in conjunction with fig. 2.

In step S201, N line pitches of the two-dimensional model in the silhouette image are acquired.

In an exemplary embodiment, after M silhouette pictures are obtained, N line pitches of the two-dimensional model in each silhouette picture need to be obtained, where N is a positive integer.

In step S202, for each of the M silhouette pictures, parameters for stereoscopically implementing the two-dimensional model are obtained according to N line pitches of the two-dimensional model in the silhouette picture, so as to draw based on the parameters, and M three-dimensional models are obtained.

In an exemplary embodiment, for each silhouette image, the model thickness at the N lines is determined according to the pitch of the N lines in a preset proportional relationship, and the model thickness is used as a parameter for stereoscopically transforming the two-dimensional model. For example: the line-to-line spacing is 1 cm, then one can rely on 1:1, setting the thickness of the model at the two lines to be 1 cm, and correspondingly setting the three-dimensional parameters of the two-dimensional model at the two lines to be 2 cm; similarly, if the distance between the other two lines is 2 cm, the thickness of the model at this point can be set to 2 cm, that is, the three-dimensional model at this point has a three-dimensional parameter of 2 cm.

In an exemplary embodiment, after obtaining the two-dimensional model stereographic parameters (i.e., model thickness), the corresponding locations of the two-dimensional model need to be stretched according to the parameters, such as: the thickness of the former was 1 cm, and then the former was raised forward by 1 cm during stretching, and the stretched former was drawn in 3Ds MAX. And respectively carrying out the same processing procedure on the M silhouette pictures, and drawing to obtain corresponding M three-dimensional models.

In step S203, the M three-dimensional models are spliced to obtain a three-dimensional model corresponding to the planar picture.

In an exemplary embodiment, after obtaining M three-dimensional models corresponding to the two-dimensional models, the M three-dimensional models obtained by stitching the planar pictures need to be compared to obtain the three-dimensional models corresponding to the planar pictures.

In an exemplary embodiment, after the three-dimensional model corresponding to the planar picture is obtained, rendering processing is further required to be performed on the three-dimensional model by comparing the planar picture, so as to achieve the effect of restoring the picture and improving the fidelity of the picture. Fig. 3 schematically shows a flowchart of a method for processing a planar picture according to still another embodiment of the present invention, and specifically shows a flowchart for rendering a resulting three-dimensional model.

Referring to fig. 3, the method provided by this embodiment includes step S301 and step S302, and step S203 is explained below in conjunction with fig. 3.

In step S301, texture drawing is performed on the three-dimensional model with the texture of the two-dimensional model in the planar picture as a reference; and/or coloring the three-dimensional model by taking the color of the two-dimensional model in the plane picture as a reference.

In an exemplary embodiment, after obtaining the three-dimensional model corresponding to the planar picture, if there are multiple three-dimensional models corresponding to the same planar picture, it is necessary to confirm the line position in the body paint 3D first, and after confirming the line position, the three-dimensional model is only a basic model with three-dimensional sense, and lacks color and texture. Therefore, it is necessary to perform texture drawing and coloring processing on the three-dimensional model, so that the model achieves the display effect identical to that of the original plane picture.

In an exemplary embodiment, the three-dimensional model corresponding to the plane picture needs to be put into Adobe Photoshop software, and then texture drawing is required to be performed on the three-dimensional model corresponding to the plane picture according to textures of the two-dimensional model in the original picture; if the plane picture is a gray picture, no coloring treatment is needed; and if the plane picture is a color picture, coloring the three-dimensional model corresponding to the plane picture according to the color of the two-dimensional model in the plane picture.

In step S302, based on the display size of the two-dimensional model in the planar picture, the display size of the three-dimensional model in the engine is adjusted according to a second preset proportional relationship.

In an exemplary embodiment, after texture drawing and coloring processing are performed on the three-dimensional model corresponding to the planar picture, a complete three-dimensional model can be obtained. Furthermore, the complete three-dimensional model is put into a NeoX game engine according to the display size of the two-dimensional model in the plane picture, and the display size is 1:1 to adjust the display size of the three-dimensional model to achieve the display effect of the highest reduction degree of the two-dimensional model in the complete model and the plane picture. The display proportion can be set according to the actual situation, and belongs to the protection scope of the invention.

After the three-dimensional model in step S102 is determined through the embodiments shown in fig. 2 and fig. 3, with continued reference to fig. 1, in step S103, a projection removing process is performed on the three-dimensional model to obtain a picture to be displayed, so as to complete the three-dimensional display of the plane picture.

In the exemplary embodiment, after the display size is adjusted, in the NeoX game engine, the three-dimensional model needs to be subjected to a projection removing process, and the projection removing process is performed to better restore the planar effect of the planar picture (ancient picture), so that the planar effect of the planar picture is achieved, the model is planar, the character is stereoscopic, that is, the display effect of 'the character walks in the picture', the modeling sense of the ancient picture is ensured, and the realistic effect of stereoscopic display of the planar picture is achieved.

The following describes an embodiment of the apparatus of the present invention, which may be used to execute the above-mentioned processing method of a planar picture of the present invention.

Fig. 4 schematically shows a block diagram of a processing device for a flat picture according to an embodiment of the invention, which may be provided in a server for processing flat pictures.

Referring to fig. 4, a block diagram 400 of a processing apparatus for plane pictures according to an embodiment of the present invention includes the following modules: a clipping module 401, a rendering module 402 and a processing module 403. The details are set forth below:

and the shearing module 401 is configured to shear the two-dimensional model according to the contour of the two-dimensional model in the plane picture, so as to obtain a silhouette picture.

In an exemplary embodiment, in 3Ds MAX software, a two-dimensional model in an ancient painting or other painting photograph may be selected for outer contour clipping to obtain a silhouette picture. The shearing angle can be set to be a uniform 30-degree fixed viewing angle in a top view, because the 30-degree angle in a top view is the most perfect shearing angle obtained by testing a large number of viewing angles. Of course, according to actual needs, other shearing angles can be set, which all belong to the protection scope of the invention.

In an exemplary embodiment, the planar image may include a plurality of two-dimensional models (for example, M are positive integers), so that the clipping module is configured to clip the M two-dimensional models according to line outlines of the M two-dimensional models in the planar image, to obtain corresponding M silhouette images.

And the drawing module 402 is configured to obtain parameters for stereoscopically drawing the two-dimensional model according to the line spacing of the two-dimensional model in the silhouette image, so as to obtain a three-dimensional model based on the parameters.

And the processing module 403 is configured to perform a projection removing process on the three-dimensional model to obtain a picture to be displayed, so as to complete the stereoscopic display of the planar picture.

In an exemplary embodiment, the processing module is configured to draw a texture of the three-dimensional model with reference to a texture of the two-dimensional model in the planar picture; and/or coloring the three-dimensional model by taking the color of the two-dimensional model in the plane picture as a reference.

In an exemplary embodiment, after obtaining the three-dimensional model corresponding to the planar picture, if there are multiple three-dimensional models corresponding to the same planar picture, it is necessary to confirm the line position in the body paint 3D first, and after confirming the line position, the three-dimensional model is only a basic model with three-dimensional sense, and lacks color and texture. Therefore, the processing module needs to perform texture drawing and coloring processing on the three-dimensional model, so that the model achieves the display effect identical to that of the original plane picture.

In an exemplary embodiment, the three-dimensional model corresponding to the plane picture needs to be put into Adobe Photoshop software, and then the processing module needs to draw the texture of the three-dimensional model corresponding to the plane picture according to the texture of the two-dimensional model in the original picture; if the plane picture is a gray picture, no coloring treatment is needed; if the plane picture is a color picture, the processing module needs to perform coloring processing on the three-dimensional model corresponding to the plane picture according to the color of the two-dimensional model in the plane picture.

In an exemplary embodiment, the processing module is further configured to adjust a display size of the three-dimensional model in the engine according to a second preset scaling relationship based on a display size of the two-dimensional model in the planar picture; and carrying out projection removing treatment on the three-dimensional model to obtain a picture to be displayed so as to finish the three-dimensional display of the plane picture.
