| 摘 要： | 本文结合高速公路建设勘察,采用无人机数码航空摄影测量系统进行航测制图,以试验大比例尺带状地形图的航测方法及其精度。结果表明,在常规控制布点条件下,基于单台普通数码相机摄影的无人机作业,能够满足对成像比例尺放大10倍测图的平面精度要求,但尚不能达到相应的高程精度要求;准确消除普通数码影像系统误差是提高该技术航测精度的关键。

| Abstract: | This paper introduced the technology for aerial surveying large-scale zonal topographic map and its accuracy,by use of an UAV photogrammetry system,and the applied case of Fujian highway construction investigation in Jiangsu province.The results showed that,in conventional control conditions,with a single digital camera,the aerial surveying accuracy could meet the standard demand when the measuring scale of topographic map is the 10 times of the map's,but the height accuracy is unsatisfying.Accurately eliminating the systematic error of common digital camera image becomes the key point to improve the precision of UAV aerial photogrammetry. |
