3.2.4 PhotoModeler Scanner Software<br />
INSTRUMENTS AND SOFTWARE<br />
The software provides the tools to create accurate, high quality 3D models <strong>and</strong> measurements<br />
from photographs. This process is called photo-based 3D scanning. Results are similar as<br />
from laser scanner. This scanning produces a dense point cloud from photographs of textured<br />
surfaces. The software includes also meshing, filtering <strong>and</strong> clean up tools. Matching may be<br />
done by using coded targets, or not coded or without any targets – then the SmartMatch<br />
function may be used by the software. It is also possible to measure circular target with subpixel<br />
precision, based on advanced computer vision techniques. This software provides also<br />
camera calibration with its own calibration chart. More information about the software can be<br />
found on the webpage: http://www.photomodeler.com/ (PhotoModeler, 2011)<br />
3.2.5 Autodesk Project Photofly - Photo Scene Editor 2.0 Software<br />
Autodesk‟s software, which is available for free to download from the Autodesk‟s website. It<br />
is open source software available for everyone. It allows anyone with a digital camera to<br />
create 3D models from photographs thanks to advanced computer vision technologies<br />
developed by Autodesk. Project Photofly automatically converts photographs into “Photo<br />
Scenes”, which includes photorealistic 3D model. Uploaded Images to a server are being<br />
processed <strong>and</strong> ready Photo Scene file is sent back once the computation is over. While<br />
waiting for computations there is no need to have open window – it is possible to ask for an email<br />
when it will be finished. When the Images are stitched properly, a draft mesh is<br />
computed automatically always as a result. However, we may refine the mesh, change quality<br />
for Mobile, St<strong>and</strong>ard <strong>and</strong> Maximum:<br />
� Mobile – fast, medium resolution mesh, suitable for viewing on mobile devices;<br />
� St<strong>and</strong>ard – high resolution textured mesh, best for visualization on the desktop, or<br />
� Maximum – very high density mesh, suitable for manipulating in external<br />
applications.<br />
The software also provides simple cleaning the 3D mesh, defining referenced points <strong>and</strong><br />
distances or defining coordinate system. It is also possible to make some measurements on a<br />
model, create lines <strong>and</strong> polylines.<br />
The software allows creating an animation <strong>and</strong> a movie <strong>and</strong> exporting to e.g. YouTube.<br />
Photo Scene Editor is very easy to use <strong>and</strong> anyone may use, because of free availability.<br />
There is also no need to have a very specific camera; it is commercial software for everyone.<br />
The Project Photofly 2.0 technology preview will expire on December 31,2012. More<br />
information about the software, <strong>and</strong> the software may be downloaded from the webpage:<br />

Appendix A. 3 represents software comparison on many different fields <strong>and</strong> introduces to<br />
main features <strong>and</strong> used tools in the project.<br />
