摘　　要：城市建成区是城市建设发展在地域分布上的客观反映,是智慧城市建设的主要区域。针对城市建成区地物信息丰富、区域面积较大等特点,提出利用国产固定翼航测无人机获取城市建成区高分辨率影像数据,完成建成区1∶500大比例尺地形图快速更新的技术方法,并对成果精度和作业效率进行检测对比。结果表明,该方法在城市建成区地理信息快速更新中具有较好适用性。The urban built-up area is the objective reflection of regional distribution of urban construction and development,and is the main area of smart city construction.In view of the characteristics of the urban built-up area,such as rich terrain information and large area.In this paper,technical method of using domestic fixed-wing mapping UAV to obtain urban high-resolution image data has been put forward.Rapid update of topographic map of the built-up area with the scale of 1∶500 has been completed,and the accuracy of the results has been tested.It is showed that this method has good applicability in rapid updating of geographic information in urban built-up areas.
