| 摘 要： | 结合现代数字摄影测量原理、数据库接口技术及Ransac鲁棒分析算法开发出基于无人机影像特点的数字摄影测量系统。主要介绍了该系统的设计思路及核心技术的实现原理。系统首先通过自动化的影像匹配获取同名点,再由相对定向和绝对定向生成3维离散点,最后构建可量测的3维DEM模型。该系统已用于实际工程,具有较高的准确性和实用性。

| Abstract: | Combined with modern digital photogrammetry principle,database interface technology and Ransac robust analysis algorithm,a digital photogrammetry system based on Unmanned Aerial Vehicle has been developed and the design ideas of the system and the realization of the core technology principle are introduced.Firstly,the identical points are obtained through automated image matching.Then,3D discrete points are generated by relative orientation and absolute orientation.Finally,3D measurable digital elevation models are established.The system has been used in the practice of engineering and shows high accuracy and practical applicability. |
