无人机倾斜摄影在靖边县龙洲丹霞地貌调查中的应用

APPLICATION OF UAV TILT PHOTOGRAPHY TO LONGZHOU DANXIA LANDFORM SURVEY IN JINGBIAN COUNTY

以陕西省榆林市靖边县龙州乡丹霞地貌调查为背景,依据倾斜摄影测量的原理及应用方法,阐述了多旋翼无人机搭载倾斜摄影设备进行数据采集影像数据,并对工作区进行实景三维建模处理,通过对实际工作中三维倾斜摄影应用实例进行探讨,结合地面调查成果,对三维建模效果进行分析,还原工作区地形地貌、增强地质遗迹资源空间辨识率、提高地质遗迹点定位精度的效果,为准确获取地质遗迹资源分布范围及规模形态提供了技术支撑。

According to the principle of oblique photography survey, tilting photography equipment loaded on multi-rotor UAV has been used for data acquisition and 3 D modeling of the Danxia Landform in Longzhou village of Jingbian County, Shaanxi province. Combined with ground survey results and based on analysis of 3 D modeling effect, the original topography and geomorphology in the working area has been restored and the spatial recognition rate of georelics is increasd for providing the technical support for accurately obtaining the distribution range and the scale of the geological heritage resources.
