Analytical inflight calibration of an aerial mapping camera
Abstract
A combined aerial triangulation and/or camera calibration program is used to determine camera focal length, symmetric radial lens distortion, and decentering lens distortion of an aerial mapping camera. It is shown that analytical in-flight aerial camera calibration of symmetric radial lens distortion is feasible using a relatively small test field (2 km x 1 km) and large-scale photography (1:3000). However, decentering distortions are not consistent and test field terrain relief is not enough to provide a sufficiently accurate calibrated focal length. No evidence is found that analytical in-flight aerial camera calibration is superior to laboratory calibration.
