摘要: 针对工业区地表地物情况复杂、控制点布设不便的问题,提出了研究该特殊区域控制点个数与摄影测量成图精度关系的方法,以求用尽量少的控制点获取精度最高的摄影测量成果。以山东省某煤矿厂区旋翼无人机航拍为例,设置航高100 m,获取影像245景,设计了3、5、7、9、11、13、15、17、19九个等级的控制点数目,并设参照组消除了控制点布设方案引起的误差。分析得出结论,成果精度随控制点个数增加而提高,控制点增加到11个时竖直方向精度达到最优,增加到15个时水平精度达到最优。为以后类似情况无人机摄影测量工作控制点个数的选取提出了建议。

Abstract: In view of the complexity of the topography and surface features of industrial areas,and the inconvenience of the control point setting,the paper presents a method to study the relationship between the number of control points and the photogrammetric mapping accuracy in order to obtain the most accurate photogrammetric results with as few control points as possible.Taking the aerial photography of rotor unmanned aerial vehicle above a coal mine in Shandong province as an example,the flight height is set at 100 m,images of 245 spots taken,9 levels of the control point number,3,5,7,9,11,13,15,17 and 19,designed,and a reference group arranged to eliminate the error by the control point setting scheme.The analysis reflects that the result accuracy rises in direct proportion to the number of control points.When the control points are increased to 11,the vertical accuracy will reach a maximum and so will the horizontal accuracy if the number is 15.Therefore,this paper provides reference to the choice of the control point number for UAV photogrammetry in similar cases in future.

Key words: industrial zones, rotor unmanned aerial vehicle, photogrammetry, accuracy, the number of control points
