| 摘 要： | 近年来随着无人机航摄技术和实景三维建模技术逐渐成熟,人们逐渐探索使用实景三维模型进行1∶500地形图采集编绘。这种编绘与传统的立体像对测图不同,是一种直观的基于模型的采集。它与立体测图相比各有优缺点,精度控制相对较弱,但因其属于基于摄影测量成果的采集,因此可一次建模,多次使用。本文讨论了实景三维模型地形图编绘软件的研发技术流程,并且针对具体案例,对该软件编绘的效率和精度进行了分析。

| Abstract: | Recently,with the maturity of the UAV aerial photography technology and the real 3D modeling technology,people gradually use the real 3D model for the 1〖DK〗∶500 topographic map acquisition and compilation.This kind of compilation is different from the traditional stereo image mapping,and it is an intuitive model-based acquisition.It has advantages and disadvantages compared with the stereo mapping.It’s based on the photogrammetric results;the usage is much easier;the 3d model can be used for other purposes.But its accuracy control is relatively weak.Therefore,this paper discusses the development of the real 3d model topographic map compilation software,and analyzes the efficiency and accuracy of the software for specific cases. |
