城市基础设施普查方法

Method of Urban Infrastructure Census

基于无人机低空航摄系统制作的高分辨率正射影像,探讨城市基础设施普查的适宜方法。通过采用以内业影像解译为主,外业补测为辅的作业方法,对城市基础设施进行高效能、低成本地普查,获取了现势性强、精度高、数据内容完整的城市基础设施普查成果。该方法相对于以外业实测为主普查城市基础设施的方法更加高效、适用。

Based on the high-resolution orthophoto images produced by unmanned aerial vehicle（UAV） low-altitude aerial photography system,this paper discusses a suitable method of urban infrastructurecensus. By adopting the operation method of mainly interpreting internal images and supplemented by the fieldsurvey,the high-performance and low-cost census of urban infrastructure was carried out,and the results of urban infrastructurecensuswith strong present situation,high accuracy and complete data content were obtained. Comparing with the field survey method,the proposed method is more efficient and applicable.
