摘要:
介绍了倾斜摄影测量方法、数据采集的基本原理,并对新疆皮山县附近20.08 km2的研究区进行了低空倾斜摄影测量数据采集与处理,获取了3.39 cm高分辨率DOM、DSM数据、9 cm分辨率的三维实景模型,以及等高线、坡度图等DSM衍生数据; 其次,依据152个地表像控点对DOM、DSM数据完成了精度评定,其点位平面中误差1.7 cm,高程中误差5.3 cm; 最后,借助上述高分辨率数字高程模型,对研究区内断层陡坎进行了地貌解译,提取了断层陡坎的垂直位移量:F1-2为(3.71±0.62)m、F2-3为(3.54±0.04)m、F3-4为(6.06±0.22)m、F4-5为(7.43±0.56)m、F5-6为(5.52±0.18)m、F6-7为(13.05±0.33)m。通过倾斜摄影测量技术获取了传统航测与卫星影像难以直接获得的具有真实地理坐标、可任意视角浏览与量测的三维实景模型,并提取了高精度的断层陡坎垂直位移值,显示了该技术在活动构造定量研究中具有广阔的应用前景。
Abstract:
In this paper,the oblique photogrammetry technology is introduced into the quantitative research of geological active structures.Firstly,the basic principle of the data acquisition and processing of tilt photogrammetry is introduced,and the data acquisition and processing of the low-altitude,tilt photogrammetry are carried out in the study area of 20.08 km2 in Pishan County,an earthquake-prone area in Xinjiang.The 3.39 cm high-resolution data of DOM,DSM,the 3D real scene modeling of 9 cm resolution,and DSM data such as contours,slopes are obtained.Secondly,according to 152 surface image control points,the accuracy of DOM and DSM data is evaluated,and the mean square error of the point plane is 1.7 cm,and the mean square error of elevation is 5.3 cm.Finally,with the help of the above-mentioned high-resolution digital model,the geomorphological interpretation of fault scarps in the study area was realized,and the vertical displacement of 7 terraces scarps was accurately extracted:F1-2(3.71±0.62)m,F2-3(3.54±0.04)m,F3-4(6.06±0.22)m,F4-5(7.43±0.56)m,F5-6(5.52±0.18)m,F6-7(13.05±0.33)m.Through oblique photogrammetry,the 3D real model,which is difficult to obtain by traditional aerial and satellite images,is directly obtained,and can be browsed and measured from any angle of view.The vertical displacement of terrace with real geographic coordinates is extracted too.The tilt photogrammetry technique has a broad application prospect in the quantitative study of geological active structures.
