重庆歇台子站示范区地表倾斜摄影模型数据集

1) 重庆市歇台子地铁站地表倾斜摄影模型，数据体量9.46G； 2) 单体化建筑面和交叉路口面矢量数据，数据体量513KB; 倾斜三维建模使用Context Capture 软件进行，将获取的4个架次5个方向影像数据、差分GPS数据，连同像控点成果一同加载到软件平台中，经过多视角影像密集匹配、区域网平差、三维TIN网构建、白模创建、纹理贴图以及模型成果输出等环节，得到OSGB格式的倾斜实景三维模型成果。为验证本次倾斜三维建模达到的精度水平,将外业过程中采集的特征检查点叠加到倾斜实景三维模型上，分别进行平面和高程精度的检核，其对应的XYZ方向残差统计。1) Oblique photogrammetry model of the ground surface of Xietaizi Subway Station in Chongqing, with a data volume of 9.46 GB; 2) Vector data of individual building facades and intersection surfaces, with a data volume of 513 KB; The oblique 3D modeling was conducted using Context Capture software. The acquired image data from 4 sorties in 5 directions, differential GPS data, and the ground control point (GCP) results were loaded into the software platform. Through processes including multi-view image dense matching, block adjustment, 3D TIN network construction, blank model creation, texture mapping, and model result output, the oblique real-scene 3D model in OSGB format was obtained. To verify the accuracy level achieved by this oblique 3D modeling, the feature check points collected during field surveys were superimposed onto the oblique real-scene 3D model, and the planar and elevation accuracy were inspected respectively, with the corresponding residual error statistics in the X, Y and Z directions.
