【摘要】：高精度、高分辨率的地形地貌数据是活动构造定量研究的基础。摄影测量方法的出现和快速发展为获取高精度地形地貌数据提供了一种经济有效的技术手段。相比于传统的测量方法,摄影测量方法可在大范围内同时进行,不受地面通视条件的限制,且测量成本相对较低。尤其近年来,随着计算机视觉理论及高效的自动特征匹配算法的发展,一种名为"Structure from Motion"(SfM)的三维重建技术被引入摄影测量方法中,极大地提高了摄影测量的自动化程度。文中介绍了摄影测量方法的基本原理及发展历程,并综述了摄影测量方法在活动构造研究中的应用,最后通过SfM摄影测量方法在活动构造研究中的1个具体应用实例,展示了摄影测量方法在活动构造定量研究中的巨大应用潜力。
[Abstract]:High precision, High-resolution topographic and geomorphological data are the basis of quantitative study of active structures. The appearance and rapid development of photogrammetry provide an economical and effective technical means for obtaining high-precision topographic and geomorphological data. Photogrammetry can be carried out simultaneously in a wide range of areas, without the limitation of common ground viewing conditions, and the cost of measurement is relatively low. Especially in recent years, with the development of computer vision theory and efficient automatic feature matching algorithm, A 3D reconstruction technique called "Structure from Motion" is introduced into photogrammetry, which greatly improves the automation of photogrammetry. The basic principle and development of photogrammetry are introduced in this paper. The application of photogrammetry in the study of active structure is summarized. Finally, a concrete application example of SfM photogrammetry in the study of active structure is given. The great application potential of photogrammetry in quantitative study of active structure is demonstrated.
