摘要
倾斜摄影测量技术有专门的软件进行处理和建模,能够快速高效地构建出质量好,精度高的实景三维模型。但此技术不能精确地对三维(3D)模型进行精度评价,由于数据的特殊性,导致建模出来的三维模型是一个整体,无法知道评定模型内部的精度。选取河北工程大学新校区部分场地为试验区域进行分析,先通过Smart3D对实验区构建实景三维模型,然后通过实地的控制点坐标结合模型从多方面进行精度评价。
Tilt photogrammetry technology has special software for processing and modeling,which can quickly and efficiently build a real three-dimensional(3D)model with good quality and high precision.However,this technology can not accurately evaluate the accuracy of the three-dimensional model.Due to the particularity of the data,the three-dimensional model is a whole,and the internal accuracy of the evaluation model can not be known.Some sites in the new campus of Hebei University of engineering were selected as the experimental area for research and analysis.Firstly,the real 3D model of the experimental area was constructed through smart3d,and then the accuracy was evaluated from many aspects through the field control point coordinates and the model.
