Building edge automatic fusion transition method and device based on depth detection

Abstract

The invention provides a building edge automatic fusion transition method and device based on depth detection, and the method comprises the steps: carrying out the region division of a virtual scene, obtaining a plurality of sub-regions, and generating a mask image sequence and a fusion transition region; performing Gaussian blur processing according to the mask image sequence, and determining a fusion transition region; when a terrain material is rendered, indexing the mask image sequence according to the position of a current pixel point, and determining a corresponding target mask image; and performing automatic fusion transition on the building edge according to the final color value obtained by performing hybrid calculation on the fusion transition region and the target mask image, so that the mask can be automatically generated, and the building edge and the terrain are subjected to material mixing, thereby obtaining a natural edge transition effect, enhancing the sense of reality, and being low in map sampling overhead and small in calculation amount.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a method and device for automatic fusion and transition of building edges based on depth detection. Background technique [0002] In the traditional simulation, the edge of the building model has the problem of hard trimming, and the transition effect between the edge of the building and the terrain is poor and lacks realism. [0003] And when the virtual simulation scene is too large, two problems will arise. The first problem is to ensure the accuracy of the fusion transition. The resolution of the Mask texture as a mask will be very high, which will result in a lot of texture sampling overhead at runtime. ;The second problem is that when the scene is too large, there may be new, modified or deleted buildings in some areas, causing the rendering target to be updated frequently, while the buildings in most other areas remain unchanged, which causes great redundancy. amo...

AI Technical Summary

Problems solved by technology

[0002] In the traditional simulation, there is a problem of hard cutting edge at the edge of the building model, the transition effect between the edge of the building and the terrain is poor, and the lack of realism

[0003] Moreover, when the virtual simulation scene is too large, two problems will arise. The first problem is that in order to ensure the accuracy of the fusion transition, the resolution of the Mask texture used as the mask will be very high, which will cause a large texture sampling overhead during runtime. ; The second problem is that when the scene is too large, there may be new, modified or deleted buildings in some areas, which will cause the rendering target to be updated frequently, while the buildings in most other areas remain unchanged, which causes great redundancy Calculations
