Calibrations of digital aerial cameras

Abstract

Aerial photography is one of the most effective sources of information to obtain data and examine the condition of different areas of the earth's surface. Their most important role is in the production of maps, as a fresh source of data is essential for their production. Remote sensing and photogrammetry have become increasingly intertwined to this day. The aim of the paper is to describe the calibration process of digital aerial cameras. Calibration is essential for aerial photography for engineering purposes, as without it we would get inaccurate, error-laden results. Three cameras were calibrated, two with an Hasselblad A6D-100c sensor with an R 50 (visible in the visible light range) and one with an IR 50 II lens with an IR (infrared in the range). AgiSoft Metashape software was used to examine the geometric calibration. For radiometric calibration, Hasselblad's Phocus image processing program. My work is part of a "live" task, as I spend my internship at Envirosense Hungary Kft.
