摘要/Abstract

摘要： 传统地质勘查野外工作不仅费时,还给地质人员带来了较为烦琐的外业工作量。本文利用倾斜摄影测量构建了新疆西昆仑山北麓面积约20 km²区域的分辨率为3.39 cm的三维模型,以及DOM、DSM等数字成果,并对其进行了精度评价。此外,基于DSM数据衍生了研究区域的坡度图,借助该高精度数字成果对研究区域地质构造进行了微地貌解译,精确提取了内部两条大型阶地陡坎的垂直错断量。通过本次倾斜摄影测量在地质勘查中的成功运用,表明该技术能够大大减轻地质学家的野外工作量,提高了效率,在地质勘测、地形微地貌解译及其定量参数提取的工作领域中具有广阔的应用前景,为地质人员提供了一种强有力的技术支撑。

Abstract: The field work of traditional geological exploration is not only time-consuming, but also brings more cumbersome field workload to geologists. Using tilt photogrammetry and three-dimensional real scene modeling technology, the digital achievements such as 3D model, DOM and DSM with high resolution and covering an area of about 20 km² and 3.39 cm in the north foot of West Kunlun Mountain in Xinjiang are constructed, and their accuracy is evaluated. In addition, slope map of the study area are derived based on the DSM data. With the help of the high-precision digital results, the micro geomorphic interpretation of the geological structure of the study area is carried out, and the vertical fault quantities of the two large terrace scarps inside are accurately extracted. The successful application of this tilt Photogrammetry in geological exploration shows that this technology can greatly reduce the field workload of geologists and improve the efficiency. It has broad application prospects in the fields of geological survey, topographic micro geomorphic interpretation and quantitative parameter extraction, and provides a strong technical support for geologists.

Key words: tilt photogrammetry, accuracy evaluation, geological exploration, geomorphic interpretation, quantitative parameters
