Calibración de cámara digital aérea de gran formato

Abstract

During the summer of 2007 a specific photogrammetric flight was executed to try to make the contrast and calibration of the geometric parameters of an aerial digital camera of large format, UltraCamD model. This photogrammetric flight was made in the “Principado de Asturias” and it has been designed with a GSD of 6 cm formed by two strips perpendicular between each other, with five images each one and a longitudinal overlap of 60%. Numerous points have been presignalled over the ground, both check points and control points. The established configuration allows us to calibrate the just mentioned camera, applying a strategy of usual calibration in terrestrial photogrammetry to an aerial camera. The calibration of digital cameras of large format used in aerial photogrammetry is a current theme, where on the European level it has been finished the project of EuroSDR “Digital Camera Calibration”, from which other three projects have emerged.
