Abstract
由於攝影測量感測器的快速發展，整合GPS/INS的直接定位系統以及數位航空相機（或稱攝影機）能提供更便捷的航測方位獲取、較佳的像片輻射品質及交會幾何。除此之外，蓬勃發展的空間資訊中建構各類型圖資，在特徵多元及數量豐富的優勢上足資扮演物像對應的控制角色。航測應用廣泛，在不同工作任務上，以上諸多特性也許能全然整合或僅能發揮部份功能，因此針對整合效能的分析以及在精度門檻內可搭配的組合配置探討便成為非常有意義的工作。本研究目的即在建立一套進行上述分析工作的航測空中三角解算器，除了具備傳統的空中三角計算功能外，本模擬器的特色在於模擬地形幾何及航測配置，並透過具彈性的平差模式，藉由方位參數、像片觀測量以及物空間控制在誤差、幾何以及數量上的調動進行各類情境所能獲致的物空間定位精度分析。
Benefited from the newly developed photogrammetry-related sensors, GPS/INS tightly integrated with imaging system makes direct acquisitions of orientations plausible and airborne digital cameras with excellent radiometric performance and higher overlap provide good quality of imagery. In addition, versatile and distinct features inherited in geo-spatial information database show adequate potential serving as control entities geometrically linking object space and image space. Due to the diverse applications realized in photogrammetry, the afore-mentioned advantages may be seen fully exploited or partially integrated in practical usages. Therefore, a simulator considering possibilities of any kind of combinations of photogrammetric sensors and data configurations is designed in this work. The simulator includes three components: (1). Terrain simulation, (2). Bundle adjustment with self calibration, and (3). Flexible adjustment models allowing for pseudo observations for parameters. The preliminary tests show that this simulator performs well for analyzing photogrammetric networks
