| description | Photogrammetry is currently facing some challenges and changes mainly related to automation, ubiquitous processing and variety of
applications. Within an ISPRS Scientific Initiative a team of researchers from USAL, UCLM, FBK and UNIBO have developed an
open photogrammetric tool, called GRAPHOS (inteGRAted PHOtogrammetric Suite). GRAPHOS allows to obtain dense and metric
3D point clouds from terrestrial and UAV images. It encloses robust photogrammetric and computer vision algorithms with the
following aims: (i) increase automation, allowing to get dense 3D point clouds through a friendly and easy-to-use interface; (ii) increase
flexibility, working with any type of images, scenarios and cameras; (iii) improve quality, guaranteeing high accuracy and resolution;
(iv) preserve photogrammetric reliability and repeatability. Last but not least, GRAPHOS has also an educational component reinforced
with some didactical explanations about algorithms and their performance. The developments were carried out at different levels: GUI
realization, image pre-processing, photogrammetric processing with weight parameters, dataset creation and system evaluation.
<br><br>
The paper will present in detail the developments of GRAPHOS with all its photogrammetric components and the evaluation analyses
based on various image datasets. GRAPHOS is distributed for free for research and educational needs. |
