摘要
利用1∶3500、1∶6000、1∶20000三种比例尺的DMC航摄资料,在航线数不变的条件下分别采用每隔4、6、8、10、16条基线进行像控点布设,在立体测图仪上加密、纠正、测图,提取地物点其坐标与外业检测成果比较,检验其对1∶500、1∶1000、1∶5000三种比例尺成图精度的影响。
using photo-matter of 3500, 6000 and 20000 three kinds of scale, Photo-Control Points are laid every 4,6,8,10,16 baselines while air lines did not change and are encrypted, rectified, surveyed on the stereo-survey mapping apparatus, and then pick-up coordinate of spatial object point are compared with field survey check-up result to check it＇s effect to precision of 3500, 6000 and 20000 three kind of scales.
