Abstract
This paper presents a study that was conducted to determine the orientation of ALOS (Advanced Land Observing Satellite) PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) triplet images, considering the estimation of interior orientation parameters (IOP) of the cameras and using the collinearity equations with the UCL (University College of London) Kepler platform model, which was adapted to use coordinates referenced to the Terrestrial Reference System ITRF97. The results of the experiments showed that the accuracies of 3D coordinates calculated using 3D photogrammetric intersection increased when the IOP were also estimated. The vertical accuracy was significantly better than the horizontal accuracy. The usability of the estimated IOP was tested to perform the bundle block adjustments of another neighbouring PRISM image triplet. The results in terms of 3D photogrammetric intersection were satisfactory and were close to those obtained in the IOP estimation experiment.
Highlights
The images from sensors installed on orbital platforms have become important sources of spatial data
The results showed that the interior orientation parameters (IOP) computed used in toexperiment perform the bundle adjustment triplet n.2. n
That is, in experiment 3, the bundle adjustment of two triplet n.2 was performed without using in experiment
Summary
The images from sensors installed on orbital platforms have become important sources of spatial data. In this context, the images of the PRISM An important requirement for extracting geo-spatial information from ALOS images is the knowledge of a set of parameters to connect the image space with an object space. A set of parameters is composed of the exterior orientation parameters (EOP) and the interior orientation parameters (IOP). The EOP can be directly estimated by on-board GNSS receivers, star trackers and gyros. The IOP are estimated from laboratory calibration processes before a satellite is launched
