倾斜摄影测量中像控点数量对模型精度的影响研究
|
摘要
为了研究像控点数量对三维模型精度产生的影响。利用倾斜摄影测量技术方法,以云南师范大学呈贡校区东区为例,采用Smart 3D软件构建三维模型,分析3组控制点对平面和高程精度的影响,实例验证的结论是:当控制点数量为5个、9个、11个时,地面检核点Y轴精度分别为5.8cm、4.0cm、3.6cm,X轴精度分别为6.1cm、5.1cm、3.7cm,高程精度分别为6.5cm、6.1cm、5.8cm;空间检核点高程精度分别为6.5cm、4.4cm、3.3cm。
For the purpose of studying the influence of the number of image control points on the accuracy of three-dimensional models,this paper takes the East District of Chenggong Campus of Yunnan Normal University as an example,uses oblique photogrammetry technique,adopts Smart 3 Dsoftware to construct a three-dimensional model,and analyzes the influence of three groups of control points on the plane and elevation accuracy.The results of the example validation are as follows:when the number of control points is 5,9 and 11,the accuracy of Y axis of ground check points is respectively 5.8 cm and 4.0 cm,while the accuracy of X-axis is 6.1 cm,5.1 cm and 3.7 cm,the elevation accuracy is respectively 6.5 cm,6.1 cm and5.8 cm,and the elevation accuracy of space check points is respectively 6.5 cm,4.4 cm and 3.3 cm.
