| 摘 要： | 利用实际航飞资料,以及相应数据处理方法,从双Marker时间差值、每一曝光点处位置姿态数据差值以及采集相同检查点坐标差值,以国外成熟POSAV610直接地理定位的精度为参照,比较分析某国产激光50型POS直接地理定位的精度及可行性。实验表明,国产激光50型POS精度较高,具有取代国外成熟POS而从事航空摄影测量的可能。 |
| 关 键 词： | 位置姿态 国产POS 直接地理定位 精度 |

| Abstract: | The paper used the actual flight data and the corresponding data processing method,with the direct geographical positioning precision of foreign mature POSAV610 for reference,from three parts: the double Marker time difference,position and attitude data difference of each exposure point as well as the coordinate difference by collecting the same check point,analyzed the Direct Georeferencing accuracy and feasibility of a home-made laser type 50 POS(position and orientation system).Experiments showed that domestic laser type 50 POS has higher accuracy and could replace the foreign mature POS in aerial photogrammetry. |
