Compared with traditional manned airborne photogrammetry, unmanned aerial vehicle remote sensing (UAVRS) has the advantages of lower cost and higher flexibility in data acquisition. It has, therefore, found various applications fields such as three-dimensional (3D) mapping, emergency management, so on. However, due to instability UAVRS platforms low accuracy onboard exterior orientation (EO) observations, use direct georeferencing image leads large location errors. Light detection ranging...

Satellite platform vibration induced by the onboard dynamic components and exterior perturbation deteriorates stability causes attitude jitter, resulting in image distortion geometric accuracy degradation. This paper presents an jitter detection method based on images dense ground controls, which requires neither high-performance measurement devices nor specific sensor configuration like parallax observation. Attitude variations will result space discrepancies at control points, from can be...
