摘要：Passive and active digital imaging is rapidly replacing film imaging in photogrammetric data capture. The reliability, accuracy, and efficiency of airborne photogrammetry are based on calibrated, high-quality sensors and rigorous processing. The calibration processes of the digital photogrammetric airborne imaging systems are under development. Central challenges in the development of the calibration are the extensive variation in digital systems, the need for radiometric calibration, and the necessity for accurate system calibration. Test field calibration is a potential approach for determining the system calibration. An investigation was carried out on the need for and feasibility of test field calibration of the geometry, radiometry, and spatial resolution of digital photogram- metric imaging systems. A unified framework and parameterization for the calibration of these properties was devised. A prototype test field calibration methodology was developed and the need for and feasibility of the test field calibration was investigated using empirical image materials. In the empirical study, data sets from the three first-generation commercial digital photogrammetric large-format sensors, ADS40, DMC, and UltraCamD were used. The results proved the feasibility of the test field calibration; a permanent test field can be an efficient, highly automated, and reliable tool for system calibration. The test field calibration was necessary for the evaluated systems to provide the missing or invalid calibration parameters and to assess their measurement capability. The results also showed that calibration of the high quality photogrammetric systems in a test field was feasible
