基于空地影像融合技术的城市建筑三维建模研究

Three-dimensional modeling of urban architecture basedon space and ground image fusion technology

三维建模技术广泛应用于城市建筑的智能化,提高模型质量成为研究热点。基于低空倾斜影像和地面近景影像的特点,提出了一种高质量的建筑实景三维模型制作方法。通过对某高校体育馆进行三维建模完成了实例验证。验证结果表明,该方法建立的三维模型平坦程度更加清晰,在纹理和细节方面都有质的提升,精度也有较大的提高。

3D modeling technology is widely used in the intelligentization of urban architecture,and improving model quality has become a research hot spot.Based on the characteristics of low-altitude oblique images and ground close-range images,a high-quality method for producing realistic 3D models of buildings is proposed.An example verification was conducted by 3D modeling a sports arena in a certain university.The verification results show that the 3D models established by this method have clearer flatness,significant improvements in texture and details,and also have greatly improved accuracy.
