摘要
随着倾斜摄影及实景三维建模技术的发展,测绘领域对于实景三维建模自动化和精度提出了更高的要求。本文提出了一种基于机载LiDAR(light detection and ranging)点云控制的倾斜影像高精度定向方法,通过对倾斜影像空三加密点的刚性变换和基于LiDAR点云控制的影像区域网平差的非刚性优化两个步骤,实现了基于LiDAR点云的云控制,有效提高了倾斜影像空三精度,为高精度实景三维自动化建模奠定了坚实基础。
With the development of oblique photogrammetry and 3D real-world modeling technology,the automation and accuracy of 3D real-world modeline is required to be higher in the field of surveying and mapping.A high accuracy oblique imagery bundle adjustment method using airborne LiDAR point clouds as control data is proposed in this paper.Through the rigid transformation and non-rigid bundle adjustment of the pass points produced by aerotriangulation,the cloud-control based on the LiDAR point clouds is realized,which effectively improves the overall accuracy of aerotriangulation of the oblique imagery,this means that the automatic modeling of high accuracy 3D real world is very feasible.
