Re: [PD] GEM - camera lens correction or camera calibration
hi all I had problems with pix_opencv compilation (mainly due to openCV 2.4 installed instead of the packaged version 2.3). I've solved so I want to share my experience. My configuration is ubuntu 12.04 64bit, pd-extended 0.43.1_20120421 installed, openCV 2.4 Below the problems with the solutions: error 1: /usr/include/Gem/Gem/glew.h: 1149:20: fatal error: GL/glu.h: No such file or directory solved installing libglu1-mesa-dev error 2: /usr/include/Gem/Gem/RTE.h:22:18: fatal error: m_pd.h: No such file or directory solved changing line 61 of Makefile file with this line (pointing to pdextended include instead of pd): PD_INCLUDE = $(PD_PATH)/include/pdextended instead of PD_INCLUDE = $(PD_PATH)/include/pd error 3: pix_opencv_lk.cc:902:59: error: ‘cvSubdiv2DEdgeOrg’ was not declared in this scope solved with installation of legacy opencv: sudo apt-get install libcv-dev libcvaux-dev error 4: blobtrack.h:20:82: error: ‘CV_BG_MODEL_MOG’ was not declared in this scope solved: uninstalled opencv 2.4.1 and now everything compile fine with opencv 2.3 (installed through apt-get install libopencv-dev libcv-dev libhighgui-dev)! so the main problem is that pix_opencv is conflicting with opencv 2.4 in the README.TXT is correctly specified that version of opencv is 2.3 but I (failing) thought that it can be compatible. thanks a lot for the great job! ciao 2013/1/8 Antoine Villeret antoine.ville...@gmail.com hi, don't hesitate to ask here if you need help to use pix_opencv_calibration i don't know anybody using it except cyille and me and perhaps the help file is not clear enought it would be a good test :-) cheers a PS : don't forget to check the other new cool features of pix_opencv ;-) -- do it yourself http://antoine.villeret.free.fr 2013/1/8 Dario Pedrioli dariopedri...@gmail.com Thanks a lot. ciao dario 2013/1/8 Cyrille Henry c...@chnry.net hello, up to date sources are on pd externals svn, on sourceforge. http://pure-data.svn.**sourceforge.net/viewvc/pure-** data/trunk/externals/http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/ cheers c Le 08/01/2013 15:46, Dario Pedrioli a écrit : Thanks a lot Jack and Cyrille Wow!

Re: [PD] GEM - camera lens correction or camera calibration
for better lens calibration, see pix_opencv object (pix_opencv_calibration). cheers c Le 08/01/2013 13:31, Jack a écrit : Le 08/01/2013 12:50, Dario Pedrioli a écrit : Hi all, I'm trying to do a simple planar stereo vision installation (two camera that see a plane from a side) trying to reconstruct object position on the plane.
