摘　　要：采用倾斜摄影技术制作两个试验区高精度三维建模,以三维模型为基础,在不佩戴立体眼镜的真三维环境中依据所见即所得进行高精度大比例尺矢量地形数据采集工作,并对地形图、正射影像和数字高程模型进行精度验证,提出符合大比例尺测图要求的技术方法,从而大幅降低外业调绘的工作量,提高作业效率。This research uses oblique photogrammetry technique to make high-precision 3D modeling in two test areas.Based on 3D models,the data acquisition work of high-precision large-scale vector terrain is carried out in a true 3D environment without stereoscopic glasses.The precision of topographic maps,orthophoto images and digital elevation models is verified,and the technical method that conforms to the requirements of large-scale scale mapping is proposed,thus greatly reducing the workload of external mapping and improving operational efficiency.
