摘要
利用倾斜摄影测量技术能够快速获取项目区高精度实景三维模型。采用无人机平台搭载五镜头相机进行倾斜摄影测量获取项目区影像数据,使用Smart 3D软件进行数据处理,生产实景三维模型,分析利用Smart 3D软件进行实景三维建模的特点,针对生产实景三维模型速率较慢,对计算机配置要求较高等问题,提出构建Smart 3D工作集群、提高三维模型生产速率。本文利用安徽理工大学山南新校区实例数据进行实景三维模型构建,采用Smart 3D工作集群数据处理方式,进行两次空三加密以生产真实场景的三维模型,并对模型进行精度评价。结果表明,第一次空三加密时不使用像控点信息,第二次空三加密之前刺入像控点信息,可以生产出高精度三维模型,以满足测区的需求。
By using tilt photogrammetry,the high-precision 3D model of the project area can be obtained quickly.Using unmanned aerial vehicle(UAV)platform carry five lens tilt photogrammetry camera to obtain the image data,using the Smart 3D software for data processing,production of three-dimensional model of real analysis using Smart 3D software for the characteristics of 3D modeling of real live for 3D model rate slower,high requirements for computer configuration problem,put forward the construction of Smart 3D work cluster,improve the production rate of the 3D model.In this paper,real scene 3D model construction is carried out with the instance data of Shannan new campus of Anhui University of Science and Technology.Smart 3D working cluster data processing method is adopted to produce real scene 3D model by air and three encryption twice,and the accuracy of the model is evaluated.The results show that the image control point information is not used in the first air-three encryption,and the image control point information is inserted before the second air-three encryption,which can produce a high-precision three-dimensional model to meet the needs of the test area.
