A commercially-existing software solution by AgiSoft PhotoScan
[29], called PhotoScan, establishes the relation between the unordered
image data collection. This software has been recently optimized for
the use with UAV. The software's professional edition allows to georeference
the results in a specific coordinate system. It exports these
to a digital elevationmodel or orthophoto. The recommended computer
processing requirements for such large data gathering projects with
more than 100 images are a 64-bit operating system with at least 16
GB RAM.
