Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, an implementation flow diagram of a panoramic image display method provided in an embodiment of the present invention is applied to a processor, and the method specifically includes the following steps:

s101, determining the material of the texture to be replaced in the panoramic image and the target texture mapping corresponding to the panoramic image.

When the panorama display end displays, a user can select a material of a texture to be replaced in the panorama image, and the user can select a corresponding target texture mapping for the material, wherein the target texture mapping is used for replacing the texture of the material with a target texture. For example, the user a may select a wood material of the texture to be replaced in the panoramic image, and select a corresponding target texture map for the wood material, where the target texture map is used to replace the cross grain of the wood material with the vertical grain.

Therefore, the method and the device for determining the texture mapping can determine the material of the texture to be replaced in the panoramic image selected by the user and determine the target texture mapping selected by the user for the material. For example, the embodiment of the present invention determines a wood material of a texture to be replaced in the panoramic image selected by the user a, determines a target texture map selected by the user a for the wood material, and may replace a horizontal grain of the wood material with a vertical grain.

It should be noted that the panoramic image may be a panoramic image corresponding to a bedroom scene in 3D design software, a panoramic image corresponding to a kitchen scene in 3D design software, or a panoramic image corresponding to a living room scene in 3D design software, which is not limited in the embodiment of the present invention. In addition, the material here may be a wood material, a metal material, a plastic material, and the like, which is not limited in the embodiment of the present invention.

S102, searching a target diffuse reflection layer corresponding to the target texture mapping from a preset diffuse reflection layer set.

In the embodiment of the invention, the light in the panoramic image is removed, the texture maps corresponding to the materials of the textures to be replaced in the panoramic image are replaced by the candidate texture maps, the offline rendering is carried out, and the diffuse reflection layer set is output. Therefore, the diffuse reflection layer set independent of illumination is obtained through off-line rendering, and a large amount of rendering resources can be saved.

Here, the candidate texture map includes any candidate texture map of N candidate texture maps, where N is a positive integer, that is, N may be 1, 2, 3, 4, or 5 … …, so that a mapping relationship between the candidate texture map and a corresponding diffuse reflection map layer in the diffuse reflection map layer set may be established, where the diffuse reflection map layers correspond to the candidate texture maps one to one.

For example, removing light in the panoramic image, replacing a cross grain map corresponding to a wood material in the panoramic image with a vertical grain map, performing offline rendering, outputting a diffuse reflection layer A, and establishing a mapping relation between the vertical grain map and the diffuse reflection layer A;

replacing the cross grain maps corresponding to the wood materials in the panoramic image with cloud-like texture maps, performing off-line rendering, outputting a diffuse reflection layer B, and establishing a mapping relation between the cloud-like texture maps and the diffuse reflection layer B;

replacing the cross grain maps corresponding to the wood materials in the panoramic image with tree grain maps, performing off-line rendering, outputting a diffuse reflection layer C, and establishing a mapping relation between the tree grain maps and the diffuse reflection layer C;

and performing cyclic processing, if the number of the candidate texture maps is N, performing offline rendering for N times to obtain N diffuse reflection layers, wherein rendering resources consumed by offline rendering can be saved because only the N diffuse reflection layers are obtained by offline rendering, and the N diffuse reflection layers can form a diffuse reflection layer set and correspondingly establish N mapping relations.

It should be noted that the mapping relationship established here may be in a specific form of a cross grain mapping, a vertical grain mapping, a diffuse reflection layer a corresponding to the wood material, and a cross grain mapping, a cloud-like grain mapping, a diffuse reflection layer B … … corresponding to the wood material, as shown in table 1 below.

TABLE 1

Therefore, through the steps, a diffuse reflection layer set can be output, and a target diffuse reflection layer corresponding to the target texture map can be obtained through query from the diffuse reflection layer set according to the established mapping relation.

For example, for the cloud flocculent texture map, according to the mapping relationship shown in table 1 above, a target diffuse reflection layer corresponding to the cloud flocculent texture map, that is, the diffuse reflection layer B shown in table 1 above, is searched from the diffuse reflection layer set.

And S103, intercepting a corresponding area from the target diffuse reflection layer, and covering the corresponding area on the diffuse reflection layer of the panoramic image to obtain a new diffuse reflection layer.

For the target diffuse reflection layer, in the embodiment of the present invention, a corresponding area is intercepted from the target diffuse reflection layer, and the corresponding area is covered on the diffuse reflection layer of the panoramic image, so that a brand new diffuse reflection layer can be obtained.

For example, for the DIFFUSE reflection layer B corresponding to the cloud-like texture map, in the embodiment of the present invention, a corresponding area is cut from the DIFFUSE reflection layer B, and is covered with a DIFFUSE reflection layer (DIFFUSE) of the panoramic image, so that a completely new DIFFUSE reflection layer (DIFFUSE-REPLACE) can be obtained.

And intercepting a corresponding area from the target diffuse reflection layer, searching a target area from the diffuse reflection layer of the panoramic image, and covering the corresponding area in the target area, so that a brand-new diffuse reflection layer can be obtained.

For example, a corresponding area is cut out from the DIFFUSE reflection layer B, a target area is searched from a DIFFUSE reflection layer (DIFFUSE) of the panoramic image, and the corresponding area is covered on the target area, so that a completely new DIFFUSE reflection layer (DIFFUSE-REPLACE) can be obtained.

The corresponding area can be intercepted from the target diffuse reflection layer according to the relative area of the texture to be replaced in the panoramic image, the target area can be searched from the diffuse reflection layer of the panoramic image according to the relative area of the texture to be replaced in the panoramic image, and the corresponding area is covered on the target area, so that a brand new diffuse reflection layer can be obtained.

For example, as shown in fig. 2, according to the relative area of the wood material in the panoramic image, the corresponding area is cut out from the DIFFUSE reflection layer B, and according to the relative area of the wood material in the panoramic image, a target area is searched from the DIFFUSE reflection layer (DIFFUSE) of the panoramic image, and the corresponding area is covered on the target area, so that a completely new DIFFUSE reflection layer (DIFFUSE-REPLACE) can be obtained.

It should be noted that the coordinates of the relative area, the corresponding area, and the target area are consistent, and the difference is that the coordinates correspond to different layers/images. Assuming that the relative area of the texture to be replaced in the panoramic image is the central area, the central area is also intercepted from the target DIFFUSE reflection layer, the central area is also searched from the DIFFUSE reflection layer (DIFFUSE) of the panoramic image, and the coordinates and the areas of the 3 central areas are consistent.

For the relative area of the texture to be replaced in the panoramic image, the relative area can be specifically determined in the following manner: determining the output color of the material of the texture to be replaced in the panoramic image, rendering, outputting a material element layer corresponding to the panoramic image, and determining the relative area of the material in the panoramic image based on the output color of the material in the material element layer.

For a material element layer (MATID), the layer can output a region of a specified material to layer data according to a preset mapping relation between the material and an output color, so that region information of the material in the panoramic image can be determined in the material element layer (MATID) according to the specified output color.

Based on the principle, for the material of the texture to be replaced in the panoramic image, the user can set a corresponding output color, the output color can be embodied in the material element layer (MATID), one-time off-line rendering is carried out, the material element layer (MATID) corresponding to the panoramic image is output, and the relative area of the material in the panoramic image can be determined based on the output color of the material in the material element layer (MATID).

For example, as shown in fig. 3, for a wood material in the panoramic image, a user may set a corresponding output color, where the output color is embodied in a material element layer (MATID), perform offline rendering once, output a material element layer (MATID) corresponding to the panoramic image, and from the material element layer (MATID), based on the output color of the material, may determine a relative area of the material in the panoramic image.

In addition, for wood materials in the panoramic image, a user can set corresponding output colors, the output colors can be embodied in a material element layer (MATID) to perform one-time off-line rendering, a global illumination layer, a diffuse reflection layer and other element layers corresponding to the panoramic image can also be output, and the other element layers are sequentially subjected to linear attenuation and superposition to obtain a mixed layer (MIX) corresponding to the panoramic image.

Here, the remaining element layers specifically include the following element layers: reflection coating (REFLECT), refraction coating (REFRACT), highlight coating (SPECULAR), scattering coating (SSS), caustic coating (CAUSTICS), fog coating (ATMOSPHERE), exterior coating (BACKGROUND), and self-luminescence coating (SELFILLUM).

It should be noted that, for the material of the texture to be replaced in the panoramic image, the user may set a corresponding output color, where the output color may be embodied in a material element layer (MATID), perform offline rendering once, output a material element layer (MATID), a global illumination layer, a diffuse reflection layer, and other element layers corresponding to the panoramic image, and thus divide the material texture region by rendering the material element layer.

And S104, combining the new diffuse reflection layer, the global illumination layer of the panoramic image and the mixed layer to obtain a target panoramic image, and displaying the target panoramic image.

And for a new DIFFUSE reflection layer (DIFFUSES-REPLACE), a global illumination layer (RAWGI) of the panoramic image and a mixed layer (MIX), combining the three layers to obtain a target panoramic image (COLOR-REPLACE), and displaying the target panoramic image (COLOR-REPLACE).

Specifically, a new DIFFUSE reflection layer (DIFFUSE-REPLACE) and a global illumination layer (RAWGI) of the panoramic image are subjected to positive superposition, so that a completely new global illumination layer (GI) with DIFFUSE reflection can be obtained; and then, carrying out linear attenuation and combination on the new global illumination layer (GI) and the mixed layer (MIX) of the panoramic image to obtain a target panoramic image (COLOR-REPLACE), and displaying at a panoramic display end.

Therefore, the rendering effect of the similar materials can be restored by cutting and covering the DIFFUSE reflection layer and combining the layers (a new DIFFUSE reflection layer (DIFFUSE-REPLACE), a global illumination layer (RAWGI) of the panoramic image and a mixed layer (MIX), and the three are combined). Therefore, on the premise of ensuring the drawing efficiency and the drawing quality, the quantity of materials needing texture replacement and the quantity of texture maps needing replacement can be improved, and rendering resources consumed by offline rendering are reduced.

For example, as shown in fig. 4, for the reflection layer (REFLECT), the refraction layer (refrac), the highlight layer (SPECULAR), the scattering layer (SSS), the caustic layer (CAUSTICS), the fog layer (ATMOSPHERE), the exterior view layer (backthrottle), and the self-luminescence layer (selllum), linear subtraction and superposition are sequentially performed to obtain the mixed layer (MIX) corresponding to the panoramic image.

Positive film superposition is carried out on the new DIFFUSE reflection layer (DIFFUSES-REPLACE) and the global illumination layer (RAWGI) of the panoramic image, so that a brand new global illumination layer (GI) with DIFFUSE reflection can be obtained; and then, carrying out linear attenuation and combination on the new global illumination layer (GI) and the mixed layer (MIX) of the panoramic image to obtain a target panoramic image (COLOR-REPLACE), and displaying at a panoramic display end.

According to the technical scheme provided by the embodiment of the invention, the material of the texture to be replaced in the panoramic image and the target texture map corresponding to the panoramic image are determined, the target diffuse reflection map layer corresponding to the target texture map is searched from the preset diffuse reflection map layer set, wherein the light in the panoramic image is removed, the texture map corresponding to the material is replaced by the candidate texture map layer and is subjected to off-line rendering, the diffuse reflection map layer set is output, the corresponding area is intercepted from the target diffuse reflection map layer and is covered on the diffuse reflection map layer of the panoramic image to obtain a new diffuse reflection map layer, and the new diffuse reflection map layer, the global illumination map layer of the panoramic image and the mixed map layer are combined to obtain the target panoramic image and are displayed.

Therefore, the texture region of the material is identified and divided by rendering the material element layer, a large amount of rendering resources are saved by rendering the diffuse reflection layer independent of illumination, and the rendering effect of the same type of material is restored by cutting and covering the diffuse reflection layer and the layer combination technology. On the premise of ensuring the plotting efficiency and the plotting quality, the quantity of materials needing texture replacement and the quantity of texture maps needing replacement can be improved, and rendering resources consumed by offline rendering are reduced.
