OpenCV Error on Zedboard

Hi all

I managed to cross compile the OpenCV libraries for Zynq and I have included them on the SD card and set the LD_LIBRARY_PATH variable. As far as I can tell, all library functions work apart from warpPersective/warpAffine. I was wondering if anyone else had encountered similar issues with these functions and if there is a known solution. For now I have worked around the problem by using remap since I only need to scale the image.

Many Thanks
Matthew

Hi m.russell,
can you share the procedure you used to have OpenCV working on the Zedboard?
And what camera did you connected to the board?

thank you,

Roberto

Hi roberto,
After installing Xillinux(http://www.zedboard.org/node/201) on my zedboard I used this guide to install opencv on it.(before going through this read the points below)
http://www.samontab.com/web/2012/06/installing-opencv-2-4-1-ubuntu-12-04-lts/

1-I skipped sudo apt-get update sudo apt-get upgrade command as someone here reported errors with this.

2- there are some missing dependencies(ignore them) and install others
I used
sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libeigen2-dev yasm libtheora-dev libvorbis-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev

3- in the cmake command, take care not to put space after -D
I used
cmake -DWITH_TBB=ON -DBUILD_NEW_PYTHON_SUPPORT=ON -DWITH_V4L=ON -DINSTALL_C_EXAMPLES=ON -DINSTALL_PYTHON_EXAMPLES=ON -DBUILD_EXAMPLES=ON -DWITH_QT=ON -DWITH_OPENGL=ON ..
this runs completely but some installations would be missing.

4- follow the other instructions and at the end logout then login by startx at command line
