摘　　要：利用无人机进行农村土地确权具有效率高、成本低的优势。通过开展简易无人机低空摄影测量试验,采用运动恢复结构数据处理方法,得到影像外方位元素的近似值,再利用附加参数的自检校光束法进行平差,明显提高了无人机低空摄影测量的定位精度,表明该方法具有一定的实用价值;通过分析影响无人机摄影测量精度的主要因素,给出了控制无人机低空摄影测量精度的若干建议。Rural homestead ownership determination using unmanned aerial vehicle( UAV) has the advantages of high efficiency and low cost. Low-altitude UAV photogrammetry experiment was conducted to test its positioning accuracy. The simple UAV platform and ordinary digital camera effectively reduced the project cost. Through structure from motion,an approximation of the image exterior orientation elements was computed,and then a self-calibration bundle adjustment with additional parameters was undertaken,which significantly improves the accuracy of low-altitude UAV photography and thus has important practical value. By analyzing the main factors affecting the accuracy of UAV photogrammetry,the authors put forward some suggestions about the control of low altitude UAV photographic measurement accuracy.
