C.2 Setting up the environment (Qt SDK Opensource)
Downloadthe2009.04versionoftheQtSDKfromhere: ftp://ftp.qt.nokia.com/qtsdk/qtsdk-win-opensource-2009.04.exe
Do not download the last version, at the
moment our software works only with Qt 4.5.x. Run the executable that
will install on your pc the Qt Framework 4.5.3 and the Qt Creator IDE.
Unzip the archive ”STRVS-Serial Executable.zip“ in a directory of your
choice. If you receive the following error (Figure C.4) while trying to launch
the ”STRVS-Serial 046.exe“, place the executable file in the installed directory
of the Qt Framework and launch from that location.

place the executable file under Qt libraries folder.
From the ”Windows Device Manager“ under ”Ports(COM & LPT)“ find
the ”STM Virtual COM Port“ and check port number. In the example it
is ”COM4“ (Figure C.5). Use this information in the software. In the following
order, we first ”Open“ the port. Then ”Start Camera“ with the
”BlobSearch“ option. Then ”Get Image“ to check the camera started correctly.
”Continuous“ should be selected if we can to see the image as a video
stream (Figure C.6).
Since there is no mechanism to save the pictures, we capture the pictures
by taking a ”snapshot“ in the windows. The important point in capturing
the images is to set ”Zoom“ parameters to ”%100“ in order not to change
the resolution of 160x120. The images should be cut also at the orginal resolution
(160x120) from the ”snapshot“ images to achieve the correct values.
The matlab script ”color calculator“ that can be found at Appendix B.1, is
used to calculate the color histogram of the demanded object. It is advised
to take as many samples as you can, with different distances to robot and
with different illumination to have better histogram.
