| Summary: | Digital aerial cameras are near to become the predominant sensor for photogrammetric image acquisition. The technology of GPS and
IMU integrated with a digital aerial camera is a complex procedure of aerial photography with possibility of decreasing number of
necessary ground control points (GCPs) for aerial triangulation (AT). Moreover, direct georeferencing, which uses calculated parameters
by GPS/IMU directly, is undertaken for a range of projects.

In this regard determination of the geometric relationship between GPS, IMU and camera geometry is a significant factor. Also
compensation of camera rotations during the flight, which is carried out by stabilizer, plays a principle role for its successful operation.
This paper will discuss calculation of 3 requisite rotational connecting parameters of geometry of camera and GPS/IMU and revise the
effect of height on them. |
