摘要
无人机免像控航测技术已发展成为测绘行业的重要基础技术,优势在于提高航测效率、减少测绘野外工作量、丰富测绘成果等几个方面.基于飞马D200S多旋翼无人机航测系统对泰州市站前快速路航测实践进行了研究,快速生成DEM、TDOM、点云等多种成果,结合EPS三维测图软件将航测影像成果转化为线划图,经实测检验分析,航测成果精度满足大比例尺测图的要求,为城市快速路的测绘提供新的更有效、安全的方法,在无人机带状图测绘方面具有普遍借鉴意义.
Abstract
The unmanned aerial vehicle(UAV)image free aerial survey technology has developed into an important foundational technology in the surveying and mapping industry,with advantages in improving aerial survey efficiency,reducing surveying field workload,and enriching surveying results.Based on the Fei Ma D200S multirotor unmanned aerial vehicle aerial survey system,a study was conducted on the aerial survey practice of Taizhou Zhanqian expressway,rapidly generating various results such as DEM,TDOM,point cloud,and so on,combined with EPS three-dimensional mapping software,the aerial survey image results were converted into line plots.After actual testing and analysis,the accuracy of the aerial survey results met the requirements of large-scale mapping,providing a new,more effective and safe method for surveying and mapping urban expressways.It has universal reference significance in drone strip mapping.
