Expressway High Precision Oblique Photogrammetry and Accuracy Evaluation
摘要: 为满足高精度三维设计的需求，对高速路设计区交通枢纽进行高精度无人机倾斜摄影测量，通过专业软件进行数据处理，获得最终高精度的实景三维模型。利用航飞前布置测设的检查点对模型精度进行总体检查，检查结果满足高精度要求，证明了倾斜摄影测量可应用于高精度的三维设计当中。为三维设计及组织施工提供可靠的基础地理信息数据。
Abstract:
In order to meet the demand of 3d design of expressway, high-precision UVA oblique photogram-metry was carried out on the traffic hub in the design area of expressway, and data processing was carried out by professional software to obtain the final high-precision 3d real scene model. The results of the overall inspection of the model precision are obtained by using the inspection points of the pre-flight test arrangement, which meet the requirements of high precision. It is proved that the oblique photogrammetry can be applied to the high-precision 3d design, providing reliable basic geographic information data for 3d design and construction.
