摘要：UltraCamX is the newest large format digital aerial camera system by Microsoft Photogrammetry (former Vexcel) and was introduced in 2006. We present a short technical overview about the sensor and we show results from a data experiment. Images from this sensor were produced at high overlaps and used to create digital surface models. In this paper the geometric accuracy of the digital surface data and the quality of UltraCamX images are presented. UltraCamX offers to capture one frame at an interval of 1.35 seconds. This allows to producing images at high overlaps at large scale and reasonable speed of the aircraft. For the data experiment a ground sampling distance of 10cm was produced at a forward overlap of 90%. Such redundant image data can be used to improve automation and robustness during the processing of dense surface models
