摘要
随着倾斜摄影测量技术的飞速发展,实景三维模型应用于诸多领域,但基于倾斜摄影建立的三维模型存在模型拉花变形、纹理缺失等问题。本文以官厅水库典型区域为研究对象,将无人机倾斜摄影与近地摄影技术有机结合,探索提出了一种空地一体化的近景摄影测量精细化建模方法;与传统无人机倾斜摄影技术相比,构建的TIN结构更为丰富,模型视觉效果更清晰。采用空地一体化的无人机倾斜摄影三维建模方式,其构建的三维模型几何结构更精细,纹理更真实细腻,可为今后实景三维精细化建模提供技术参考。
With the rapid development of oblique photogrammetry technology,the 3D model of real scene has been applied in many fields.However,the established 3D model based on oblique photography has some problems such as model strain deformation and texture loss.This paper takes the typical area of Guanting reservoir as the research object,and organically combines the tilting photography of UAV with the near-earth photography technology.A refined modeling method of close-range photogrammetry with ground-air integration is explored and proposed.Compared with traditional UAV oblique photography technology,the constructed TIN structure is richer and the visual effect is clearer.The research shows that the 3D modeling method of UAV oblique photography based on ground-air integration has finer geometric structure and more real and delicate texture,which can provide useful technical reference and value for future refinement of 3D modeling of real scene.
