摘要
量测型相机的几何精度直接决定了其影像成果的优劣,遵循经典理论的实验室和检校场评价方法对客观条件要求较高,不容易实现。本文提出了一种基于数码影像进行空中三角测量和数字地表模型(DSM)的UCX系列航空数码像机几何精度评价方法,省去了繁琐的精密定标环节和野外作业工序,实现了对数码航空像机的定位精度估算。试验表明,UC-X系列航空数码像机影像的相对定向中误差优于2μ,绝对定向中误差约为0.5个像元。
The quality of Aerial remote sensing image is mainly determined by the geometric precision of the sensor. And the traditionalmethods require a complicated calibration field. In this paper we presents a method that combine the aerial triangulation and DEM（Digital Elevation Model） to analysis the Accuracy of geometric precision of digital images. This method saves time in accurate cameracalibration and field work compared with the traditional ways. The results show that the relative direction error of UC-X Digital camerais 2 μ, and absolute direction errors is half pixel.
