摘要
根据测区实际情况,采用全数字摄影测量地形图,UltraCam X航摄相机拍摄数码相片,VirtuoZo数字摄影测量工作站立体测图,合理布设像控点,设计满足成图比例尺精度要求的布设方案。对数字摄影航片比例尺的选择,像控点布设方案的确定,外业调绘根据测区实际情况及立体模型测图高程高程精度分析,制定作业方法,最终根据外业实际测量验证方案布设及成图比例尺的精度。
According to the actual situation of the surveyed area,it can adopt digital photogrammetric topographic maps.The digital photos taken with UltraCam X aerial camera,and VirtuoZo digital photogrammetric workstation for stereo mapping.The photo control points are deployed reasonably,and the layout program is designed to meet the accuracy requirements of the mapping scale.The operational method is established for the choice of digital air photos scale,the determination of photo control points of the layout program and the height accuracy analysis of field adjustable draw that the elevation is measured according to the actual situation of the surveyed area and the three-dimensional model.Finally,the layout program and the accuracy of the mapping scale are certified according to the field actual measurement.
