Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
FIG. 1 is a flow diagram illustrating an image processing method according to an exemplary embodiment. As shown in fig. 1, the method may include the steps of:
Each preset graph corresponds to an original texture image, the pixel adjusting instruction is used for indicating that the pixel value of the original texture image corresponding to the area to be processed is adjusted to be a target pixel value, and the target image is composed of pixels with two different pixel values.
For example, the pixels of the texture image corresponding to the partial region to be subjected to pixel adjustment on the three-dimensional model may be adjusted by identifying the pixels corresponding to the partial region in the original texture image on the three-dimensional model and performing pixel adjustment on the pixels, so that the pixel adjustment on the texture image corresponding to the partial region is realized on the premise of avoiding re-rendering the preset three-dimensional model, and the adjustment efficiency of performing pixel adjustment on the texture image corresponding to the three-dimensional model is improved. Specifically, when a user wants to perform pixel adjustment on an original texture image corresponding to some region on a preset three-dimensional model, a to-be-processed region to be subjected to pixel adjustment is marked on the preset three-dimensional model (the to-be-processed region can be understood as a range surface marked on the preset three-dimensional model), and a target pixel value to be adjusted by the original texture image corresponding to the to-be-processed region is input to trigger a pixel adjustment instruction. The preset three-dimensional model is formed by splicing a plurality of preset graphs (the preset graphs can be triangles or other polygons except the triangles), the original texture image is mapped onto the surface of the preset three-dimensional model according to a specific mode, the original texture image can be understood as a two-dimensional graph on the surface of the preset three-dimensional model and can also be called a texture map, each preset graph corresponds to one original texture image, and the original texture images corresponding to all the preset graphs form the surface texture of the preset three-dimensional model together. In addition, the method for calibrating the region to be processed may be manually calibrated by the user, or may be automatically calibrated according to an input condition set by the user (for example, the position of the region to be processed on the preset three-dimensional model).
Because the number of preset graphs forming the preset three-dimensional model is huge, and more preset graphs have no intersection relation with the region to be processed, in order to further improve the adjustment efficiency of pixel adjustment, the preset graphs which have no intersection with the region to be processed can be filtered from all the preset graphs, and all the preset graphs which have intersection with the region to be processed are taken as the intersection preset graphs. Then, each intersection preset graph and the area to be processed can be shot respectively, and a target image corresponding to each intersection preset graph is obtained. The target image may include a first pixel having a first pixel value and a second pixel having a second pixel value (the first pixel is a corresponding pixel of the region to be processed in the target image), and the first pixel value is different from the second pixel value, that is, the target image is an image formed by pixels having two different pixel values.
And 102, determining a target pixel in each original texture image according to the preset graphs, the target image and each original texture image.
For example, after the target image is obtained, first, the first vertex position of all the vertices of each intersecting preset graph on the target image and the second vertex position on the original texture image may be obtained. Then, for each original texture image, sequentially traversing each pixel in the original texture image, determining a preset pattern corresponding to the pixel (one pixel may correspond to one or more different preset patterns) according to the pixel position of the pixel, and determining whether the preset pattern corresponding to the pixel is an intersecting preset pattern. If the preset graph corresponding to the pixel is an intersecting preset graph (that is, one or more intersecting preset graphs corresponding to the pixel exist), target images corresponding to all the intersecting preset graphs corresponding to the pixel (each intersecting preset graph corresponds to one target image) are further determined. Then, the target pixel position of the pixel on each corresponding target image can be respectively determined by combining the first vertex position of each intersecting preset graph corresponding to the pixel with the position relationship between the pixel position of the pixel and the second vertex position of each intersecting preset graph corresponding to the pixel. Then, for each target image corresponding to the pixel, a pixel value corresponding to a target pixel position of the pixel on the target image may be obtained. If the pixel value is the first pixel value, the pixel is labeled "1", otherwise labeled "0". And finally, counting a first time of the pixel marked as 1 and a second time of the pixel marked as 0, and if the first time is greater than or equal to the second time, taking the pixel as a target pixel. In the above manner, the target pixel in each original texture image can be determined. Finally, the pixel value of the target pixel in each original texture image can be adjusted to be the target pixel value, so as to realize the pixel adjustment of the texture image corresponding to the region to be processed.
In summary, the present disclosure first responds to a received pixel adjustment instruction, and obtains a target image according to each preset graph on a preset three-dimensional model formed by a plurality of preset graphs and a to-be-processed area on the preset three-dimensional model, where each preset graph corresponds to one original texture image, the pixel adjustment instruction is used to instruct to adjust a pixel value of the original texture image corresponding to the to-be-processed area to a target pixel value, the target image is formed by pixels of two different pixel values, and then determines a target pixel in each original texture image according to the plurality of preset graphs, the target image and each original texture image, and adjusts the pixel value of the target pixel to the target pixel value. The method and the device can determine the target pixel needing to be subjected to pixel adjustment in each original texture image by combining the preset graph and the original texture image through the preset graph and the target image acquired from the to-be-processed area, and adjust the pixel value of the target pixel, so that the adjustment of the pixel of the to-be-processed area corresponding to the original texture image is realized, and meanwhile, the efficiency of adjusting the pixel of the original texture image can be improved.
Fig. 2 is a flow chart of one step 101 shown in the embodiment shown in fig. 1. As shown in fig. 2, step 101 may include the steps of:
For example, to further improve the adjustment efficiency of the pixel adjustment, the region to be processed may be stretched in the first direction and the second direction, respectively, to obtain a target spatial region corresponding to the region to be processed. The first direction is opposite to the second direction, and the first direction is a normal direction of a plane where the area to be processed is located. Then, a preset graph having an intersection with the target space region in the plurality of preset graphs can be used as the intersection preset graph. For example, when the predetermined pattern is a triangle, the region to be processed may be stretched by 1 meter along a normal direction of a plane where the region to be processed is located, and a direction opposite to the normal direction, respectively, to obtain a target space region in a shape of a rectangular parallelepiped. All triangles may then be traversed to determine whether each triangle is completely outside the cuboid, and if so, the triangles that are completely outside the cuboid are removed. And finally, taking the rest triangles as intersecting triangles.
Specifically, after the intersecting preset patterns are determined, each intersecting preset pattern and the region to be processed may be photographed respectively according to a preset angle (or in a screenshot manner), so as to generate a target image corresponding to each intersecting preset pattern. For example, when the preset pattern is a triangle, the target image may be a black-and-white image (at this time, the target image only includes a white pixel value and a black pixel value), as shown in fig. 3, a white area in the black-and-white image is a corresponding area of the area to be processed in the black-and-white image.
Fig. 4 is a flow chart illustrating one step 102 of the embodiment shown in fig. 1. As shown in fig. 4, step 102 may include the steps of:
For example, after the target image is acquired, vertex position information including a first vertex position on the target image and a second vertex position on the original texture image of each vertex of the intersecting preset graph may be acquired for each intersecting preset graph. Namely, the following contents need to be saved after the target image is generated: (1) the method comprises the steps of (1) corresponding relation between a target image and an intersected preset graph, (2) pixel positions of each vertex of the intersected preset graph on the corresponding target image, (3) original texture images corresponding to the intersected preset graph, and pixel positions of each vertex of the intersected preset graph on the corresponding original texture images. Wherein the first vertex position and the second vertex position may be expressed in UV coordinates.
For example, after the vertex position information is obtained, it may be first determined, for each original texture image, whether one or more target preset graphics corresponding to each pixel exist in at least one intersecting preset graphics according to a pixel position of each pixel in the original texture image. For example, which preset patterns the pixel belongs to can be determined by the pixel position of the pixel, and the preset patterns are taken as the preset patterns corresponding to the pixel, and then it is determined whether there is an intersecting preset pattern in all the preset patterns corresponding to the pixel. If the intersected preset pattern exists in all the preset patterns corresponding to the pixel, the preset pattern which is the intersected preset pattern in all the preset patterns corresponding to the pixel can be used as a target preset pattern, and at this time, one or more target preset patterns corresponding to the pixel can be determined to exist. If there is no intersecting preset pattern in all the preset patterns corresponding to the pixel, it may be determined that there are no one or more target preset patterns corresponding to the pixel.
In a case that it is determined that one or more target preset graphics corresponding to the pixel exist in at least one intersecting preset graphics, a corresponding pixel value of the pixel in the target image may be determined according to a pixel position of the pixel and vertex position information corresponding to each target preset graphics. Specifically, the target pixel position of the pixel on each target image corresponding to the pixel may be respectively determined by combining the position relationship between the pixel position of the pixel and the second vertex position of each target preset graph corresponding to the pixel and the first vertex position of each target preset graph corresponding to the pixel, and the pixel value corresponding to the target pixel position of the pixel on each target image may be obtained. The process of determining the target pixel position of the pixel on a target image is actually to deduce the target pixel position of the pixel on the target image according to the position relationship between the pixel and the target preset pattern corresponding to the target image on the original texture image, and by combining the position of the target preset pattern corresponding to the target image on the target image.
Then, for each pixel, a target pixel may be determined from the pixel value of the pixel corresponding to the target image. For example, in a case that the target image includes a first pixel having a first pixel value and a second pixel having a second pixel value, and the first pixel is a corresponding pixel of the region to be processed in the target image, a first number of times that the corresponding pixel value of the pixel in the target image is the first pixel value and a second number of times that the corresponding pixel value of the pixel in each target image is the second pixel value may be counted. If the first number is greater than or equal to the second number, the pixel is a pixel corresponding to the region to be processed, and the pixel can be used as a target pixel. Further, in a case where it is determined that one or more target preset patterns corresponding to the pixel do not exist in at least one intersecting preset pattern, the pixel may not be taken as a target pixel.
In the above manner, the target pixel in each original texture image can be determined. Finally, the pixel value of the target pixel in each original texture image can be adjusted to be the target pixel value, so as to realize the pixel adjustment of the texture image corresponding to the region to be processed.
In summary, the present disclosure first responds to a received pixel adjustment instruction, and obtains a target image according to each preset graph on a preset three-dimensional model formed by a plurality of preset graphs and a to-be-processed area on the preset three-dimensional model, where each preset graph corresponds to one original texture image, the pixel adjustment instruction is used to instruct to adjust a pixel value of the original texture image corresponding to the to-be-processed area to a target pixel value, the target image is formed by pixels of two different pixel values, and then determines a target pixel in each original texture image according to the plurality of preset graphs, the target image and each original texture image, and adjusts the pixel value of the target pixel to the target pixel value. The method and the device can determine the target pixel needing to be subjected to pixel adjustment in each original texture image by combining the preset graph and the original texture image through the preset graph and the target image acquired from the to-be-processed area, and adjust the pixel value of the target pixel, so that the adjustment of the pixel of the to-be-processed area corresponding to the original texture image is realized, and meanwhile, the efficiency of adjusting the pixel of the original texture image can be improved.
