Description
Technical Field
The invention relates to the technical field of surveying and mapping, in particular to a real-time color homogenizing method for a real-scene three-dimensional model.
Background
At present, the real-scene three-dimensional modeling by utilizing oblique photography becomes an important method for obtaining the urban three-dimensional model, and the method has the characteristics of high modeling speed, high automation degree and strong reality. The texture of the live-action three-dimensional model comes from aerial photography, and the problems of inconsistent colors, partial darkness or overexposure of aerial images and the like can be caused due to different aerial photographing time and different exposure degrees of photos, so that the color tone of the live-action three-dimensional model is not optimal, and the live-action three-dimensional model needs to be subjected to light and color evening.
Patent CN110176053A discloses a large-scale live-action three-dimensional integral color-homogenizing method, which utilizes the color difference of live-action three-dimensional in the overlapping region between blocks to establish a linear equation of the color difference between all blocks in the whole measuring area, and solves the linear equation integrally to obtain the change amount of the live-action three-dimensional color of each block, thereby achieving the effect of integral color-homogenizing.
Patent CN109712223A discloses an automatic coloring method for three-dimensional model based on texture synthesis, which adopts a texture synthesis method based on patch match to perform texture synthesis on a given model and image, and recovers the texture coordinates on the surface of the model through grid projection, thereby realizing the synthesis of model map according to the image given by the user, and automatically coloring the three-dimensional model conveniently and quickly. The whole process is fully automatic, manual intervention is not needed, and therefore the method is very suitable for automatic coloring engineering of massive models, and on the other hand, the difficulty of model coloring is greatly simplified, so that common users can color the models according to own preferences, and the method is very suitable for personalized model making and displaying.
The two technical schemes are that the original image of the three-dimensional model is subjected to light and color homogenizing treatment, and then three-dimensional modeling is carried out again. However, if the light and color homogenizing effect is still not satisfactory after the three-dimensional modeling is performed again, the process needs to be repeated, which undoubtedly increases the workload of data processing.

The rendering state set includes vertex, color and texture material information of the live-action three-dimensional model. Because the rendering state set is obtained through the detail level model, the resource allocation of object rendering can be determined according to the position and the importance of the node of the real-scene three-dimensional model in the display environment, and the number and the detail of the surface of the non-important object can be reduced, so that the position and the importance of the node of high-efficiency rendering operation in the display environment can be obtained, the resource allocation of object rendering can be determined, the number and the detail of the surface of the non-important object can be reduced, and the effect of high-efficiency rendering operation can be obtained.
The vertex shader comprises an input end and an output end, the input end inputs programs, vertex attributes, transformation matrixes, illumination and color parameters of the vertex shader into the vertex shader, then matrix transformation positions are carried out on input data, an illumination formula is calculated to generate vertex colors, and position information and image texture coordinates are generated; and sending the position information and the image texture coordinates to the fragment shader through an output end of the vertex shader. The fragment shader is used for processing each fragment generated in the image raster stage, executing various calculations, and finally calculating the final color of each pixel.
And thirdly, compiling different color homogenizing algorithms for each detail level model in a vertex shader and a fragment shader by using a GPU programming language, wherein each color homogenizing algorithm can generate corresponding adjusting parameters, and sending the compiled adjusting parameters to an external visualization program as consistency variables.

I.e. to adjust one or more of the shading parameters brightness, contrast, color components.
