Agisoft PhotoScan Standard edition
Agisoft PhotoScan Standard automatically builds professional quality
textured 3D models from still images. The program provides robust
photo alignment, no coded targets or special shooting conditions
being needed
Photo alignment
Point cloud generation (sparse / dense)

PhotoModeler Software
The PhotoModeler Software extracts 3D Measurements and
Models from photographs taken with an ordinary camera. A very
cost-effective way of doing accurate 3D scanning, measurement
and surveying

VeCAD
http://vecad.software.informer.com/
VeCAD is a 3D vector graphics library. It serves as a foundation
for your own customized drawing applications (CAD/GIS). The
library is furnished in two discreet formats; as a run-time
Windows 32 bit DLL; and, as an OCX. Both are included. The
package also includes a powerful CAD editor in executable form,
based entirely on the VeCAD engine. Use this application to
visualize your own project's possibilities!

Calib
http://calib.qub.ac.uk/
Specify the calibration algorithm. Valid algorithms are 3 and 4. Default value is 3.
Specify the touch point acceptance variance (range 0 - 2000). Enabling this will
force bound checking on touch points.
Limit the number of samples for each touch point. Default value is 15.
Offset for crosshair position, which you can use to tweak calibration. Applicable
only with 4-point calibration.
Use small touch targets. Default is large.

Taking photos of the calibration figure
Dots paper ( 9 photos )
Chess paper ( 8 photos )
Upload the pictures in the program (in Calib
and in PhotoModeler)
Processing, calculation

(PhotoModeler, PhotoScan, VeCad)

We have to take shoots of calibration paper, we need at least 6 photos of calibration
paper
Start PhotoModeler Scanner software and choose camera calibration project
then we import photos of calibration paper to our project
then we press “Execute calibration” in Automatic Camera Calibration dialog
Software automatically select points on the calibration paper and calculate the
calibration parameters
After we can see a calibration report with calculate parameters
At last we add a camera to the library and save calibration project as NIKON
D3000.pmr

Entering the area and walk around for measuring things (building, monument,
pillar, stone )
Field work ( taking photos, measuring with total station)
Measuring check distances (in the measuring things )
Upload measurements and pictures in our computer and check the ground’s
products

•We have to find object with rich geometry and
texture
•Then we have to choose camera stations
•Taking shoots from these camera stations
•If we have prepared all photos of monument, we can start PhotoModeler Scanner
software.
•We choose the Point-based project
•Import all photos of monument and assign with calibrated camera NIKON
D3000.
•We have to orient at least 4 photos, but we used 5 photos.
•For orientation we use Mark Points Mode and create point on first 2 photos.

• Than we use Referencing mode to connect the points.
•After reference we can start the Process.
•When an error was good, we can start creating points, lines and
curves.
•Then we can create a surfaces. For
surfaces we used the Path mode.
•When we have created all surfaces, we have to set a materials
for this surfaces and build textures.

Now we can define the scale. We have a

•Now we have ready 3D model of monument
•At last we can export 3D model to *.dxf, *. 3ds and *.wrl.

When we have created all surfaces, we have to
set a material for these surfaces and build
textures. For cylinder we have to create a photo
set of oriented photos. Than we make a new
material from these photos and use this material
for build texture on the cylinder.
Now we can define the scale. We have
measurements from field.


First we take some measurements of some control points with a total station and take
photos of the building that we are going to use, for rectifying the images.
then calibrate the images that we selected for the rectification.
Then we insert control points in VeCAD
Then we match the points in the image
Then we rectify the image and we match the points from the first image with the
control points in the second image.
Then we name the rectified image and specify the pixel size in the coordinates.

This work was supported by the Erasmus IP project financed by the European
Union. The authors thank the Technological Institution of Kavala for their support
and the guidance and generous support in providing hardware and software
licenses for training. We also wish to specifically thank the professional staff of The
Technological Institute of Kavala during our stay, Mr. Athanasios STYLIADIS, Mr.
Lazaros SECHIDIS, Dr. Tamás Jancsó, Mr. Vasilis TSIOKAS, Mr. Sorin HERBAN,
Dr. Laszlo GERGELY Dr. Beatrice VILCEANU, Dr. Alexandra POPA for their
valuable participation, contributions, instructions and help – our work would not
have been feasible without their gracious assistance. The authors also
acknowledgement the dedicated efforts of the Greek team members who have
made our visit here very agreeable.
Among the benefits of 3D models with PhotoModeler Scanner, we mention the
followings:
• opportunity of real image acquisition with very realistic 3D models, that are applied
in a large variety of fields;
• less time for field work, more time for data processing;
• minimizes the probability of unscanned zones due to shadowing effect of roughness
elements and overhanging zones due to proximity to the target and the possibility
of scanning from different angles and overlapping the scanning results;
• providing high precision and complex data;
• using 3D technology, 3D models can be created;
• can be combined with other well established high precision surveying techniques
