摘要
以固定翼无人机在农村地籍测量中的应用探讨为例,简单介绍了固定翼无人机航测系统的组成。对在农村地籍测量中的应用进行了阐述,包括测区概况与航摄方案设计、数据的获取与预处理、空三加密计算与精度评定。通过实地采集的检查点与空三加密结果的比较,分析和评价了无人机航测系统应用于农村地籍测量中的可行性,试验数据获得的DOM满足1∶500的成图精度要求,并将获得的DOM与原有的1∶500地形图进行套和和比较,研究表明,无人机航测系统可以满足在农村地籍测图中的任务需要。
Take an example of the practical investigation of the fixed-wing UAV in rural cadastral mapping,this paper presents a brief introduction of the fixed-wing UAV aerial system composition and its application of the cadastral survey in the countryside,including the general situation of survey area,the design of aerial photography,the data acquisition and pre-processing,the aerotriangulation and the accuracy assessment.By comparing the actual collected check points and aerotriangulation results,this paper analyzes and evaluates the feasibility of using the UAV aerial photographic system in rural cadastral survey.The experiment DOM data fits the 1∶500accuracy requirements.After comparing the DOM and the original 1∶500topographic map,this paper shows that UAV system can meet the need of rural cadastral map task.
