摘要
由于单体建筑的特殊性,倾斜摄影建模难以体现建筑物细节,而传统手动控制无人机进行贴近摄影测量又存在一定的安全隐患和效率问题。鉴于此,文章以元通塔为例提出一种以无人机倾斜摄影模型作为参考基础,精细化规划航线,使无人机能够自动化完成立面数据采集的方法。结果表明,该方法能够提前校验自动化飞行航线的安全性,具有起飞后不管的特点,其成果为厘米级精细三维模型且满足CH/T 9015—2012《三维地理信息模型生产规范》中Ⅰ级1∶500成图比例尺和Ⅰ级建筑物要素模型制作的规范要求,具有良好的应用前景。
In view of the particularity of single buildings,tilting photography modeling has the problem that it is difficult to reflect the details of buildings,while the traditional manual control UAV for nap-of-the-object photogrammetry has certain safety risks and efficiency problems.Taking Yuantong tower as an example,this paper proposes a method which takes the UAV tilt photography model as the reference basis,and makes the UAV complete the elevation data collection automatically.The results show that the method can verify the safety of automated flight path in advance,and has the characteristics of being ignored after takeoff.The results are centimeter-level fine 3D model,and meet the requirements of classⅠ1∶500 mapping scale and classⅠbuilding element model in the Production Specification for 3D Geographic Information Model(CH/T 9015—2012).It has a good application prospect.
