Geometric correction model for dual sensor pushbroom aerial camera

Abstract

Geometric correction is necessary in photogrammetry and remote sensing to avoid geometric distortions and establish relationship between image coordinate and its corresponding ground coordinate. Rigorous sensor model is one of the methods which considered the most precise and accurate for geometric correction. However, as rigorous sensor model contains many equations that depend on the actual physical properties of the sensor, the model is specialized for each sensor. In this paper, we modified a rigorous sensor model of geometric correction for pushbroom imager into geometric correction model for dual sensor pushbroom imager. The result shows that a model has been successfully obtained and can be used to geometrically correct coordinates of dual sensor pushbroom imagery.

Research on directional accuracy of pushbroom images based on different ground resolutions

“…After aerial photography uses PPP for GPS free base station flight operations, the ADS system can be used for direct aerial triangulation and mapping with only a small number of control points. This not only greatly reduces the field control measurement work and costs, but also improves work efficiency and shortens the mapping cycle [1] .…”
