| 摘 要： | 通过陕西勉县测区的POS辅助航空摄影测量试验,本文对SWDC-4搭载POS/AV 510 V5系统获取的航测数据使用直接定向法和POS辅助空中三角测量2种方法进行1∶10 000成图精度验证。结果证明:国产SWDC-4航摄仪与POS/AV系统集成进行POS辅助空三的加密成果能满足该测区1∶10 000地形图测图的平面和高程精度要求,直接定向也是可行的。

| Abstract: | This paper verified the accuracy of 1∶10 000 topographic mapping based on POS-supported aerial photogrammetry of Shanxi Mianxian survey area.The aerial photogrammetric data was acquired by SWDC-4 equipped with POS/AV 510 V5 system,the methods of Direct Georeferencing and Integrated Sensor Orientation were used.Our results showed that the densification result of Integrated Sensor Orientation method could meet the plane and elevation accuracy requirements of 1∶10 000 topographic mapping with the integration of domestic SWDC-4 aerial device and POS / AV system,Direct Georeferencing was also feasible. |
