三维数码照相技术在高边坡地质调查中的应用

摘要

ADAM 3D digital photography can be applied in survey, geological logging, deformation monitoring. At present, this technique is still in the initial application stage in China. On the basis of the introduction of its basic principle and working procedure, taking the high slope at dam site of Wudongde Hydropower Station for an example, the photomontage of the 3D digital picture, contour generation, 3D coordinate extraction of any point, trace length measurement of the structural plane and extraction of its information are described. Compared with the conventional technique, this method is effective, safe and accuracy, and has wide application prospects in geology engineering and geotechnical projects.%ADAM三维数码照相技术可以应用在测量、地质编录、变形监测等领域。目前，该技术的应用在国内仍处于起步阶段。介绍了三维数码照相技术的基本原理和工作步骤，以乌东德水电站坝址区高边坡为例，阐述了研究区三维数码照片的合成、等高线的生成、任意一点三维坐标的提取、结构面迹长的测量和结构面信息的提取，以及三维数码照相技术在水电站高边坡研究中的应用。与传统技术相比，该技术具有高效、安全、准确等优点，在地质和岩土工程领域具有较好的发展前景。
