基于PhotoScan和ArcGIS的土方量测量研究

Research on earthwork measurement based on PhotoScan and ArcGIS

针对传统测量方法工程量大,无法快速得到较为准确的数据等缺点,文中研究利用无人机、PhotoScan与ArcGIS等软件完成土方量测量的方法,使用轻小型无人机拍摄不同时期高清影像,运用PhotoScan对影像进行处理,生成数字表面模型,通过ArcGIS进行偏差适当校正,快速计算得到土方变化量。

For the traditional measurement method that the engineering quantity was large,and it was impossible to quickly obtain more accurate data and other shortcomings. In this paper,the earthwork quantity measurement was completed using UAV,PhotoScan and ArcGIS software,digital surface models were generated using light and small UAV to capture high-definition images in different periods and using PhotoScan to process images. The deviation was corrected by ArcGIS and the change amount of earthwork was quickly calculated.
