ueye

USB Ueye camera 2230-C (Imasys distributor, order n° L82729 of 22.02.2008)

appli ueyegrab modifiée pour le nouveau driver: /home/bvandepo/Desktop/ueye/ueyegrabtemp2

./ueyegrab a 10 im
./ueyegrab c 10 im

l'appli ne debayeurise plus avec le nouveau driver, refuse de sauver les images

doc faite pour l'ancien driver: https://intranet.laas.fr/intranet/robots/wiki/Manta/uEyeSoftware

la diode verte sur la ueye doit etre allumée pour pouvoir acquerir des images, sinon lancer:

sudo /etc/init.d/ueyeusbdrc start

pour regler la camera, utiliser la gui

ueyedemo

les sources sont dans /usr/src/ids/ueyedemo il y a un probleme avec l'enregistrement des images… copie en /home/bvandepo/Desktop/ueye/ueye_demo3.9b pour pouvoir arranger: c'est la fonction suivante qui déconne en ligne 937 de mainview.cpp : ret = is_SaveImageEx (m_hCamera, (char*)fileName.latin1 (), fileformat, fileparam);-

    
    
    modif pour sauver  images en séquences:
     //BVDP
      int ret;
        int fileformat = IS_IMG_PNG;
        int fileparam = 0;
        static unsigned int cpt=0;
        char chaine[1000];
        sprintf(chaine,"/home/bvandepo/Desktop/ueye/ueye_demo3.9b/im%04d.png",cpt);
        QString fileName=chaine;
        cpt++;
        ret = is_SaveImageEx (m_hCamera, (char*)fileName.latin1 (), fileformat, fileparam);
          if (ret != IS_SUCCESS)
          {
              QMessageBox::critical(this, "Error!", QString("Saving image failed with code %1!").arg(ret), QMessageBox::Ok, 0);
          }
    
    

soft avec gui modifiée pour sauver des sequences sur hd, à compiler avec kdevelop

borderouge:/home/bvandepo/Desktop/ueye/ueye_demo3/src

je n'arrive plus à la compiler, car elle utilise des vieux headers de QT3, il faudra plutot récuperer mes modifs et les appliquer à la nouvelle appli démo de ueye.

anciennement:

sudo rm /usr/lib/libueye_api.so.1
sudo rm /usr/lib/libueye_api.so
sudo ln -s /usr/lib/libueye_api.so.1.0.0 /usr/lib/libueye_api.so.1
sudo ln -s /usr/lib/libueye_api.so.1.0.0 /usr/lib/libueye_api.so

artag

copie du robotpkg dans /home/bvandepo/Desktop/monArtToolkit/

regarder le fichier INSTALL: choix config build debug ou release dans

/home/bvandepo/Desktop/monArtToolkit/build/linux/options.pro

ajouter une variable d'environnement dans le project→build ARTKP : /home/bvandepo/Desktop/monArtToolkit/sample/simple/src

marqueurs standard dans /home/bvandepo/robotpkg/image/artoolkitplus/work.borderouge.laas.fr/id-markers/simple/std-border

pour les imprimer, d'abord les agrandir sans interpolation

 convert SimpleStd_100.png -scale 10000% SimpleStd_100-resize1000.png

sudo sh ./ueyesdk-setup-3.90-usb-i686.gz.run
sudo /etc/init.d/ueyeusbdrc start

programme dans

sudo cp -r ~/Desktop/ueye/eigen-eigen-3.0.3/Eigen /usr/include/

nécessite gdhe pour faire l'affichage de la pose 3D (peut être pas obligatoire)


probleme avec les fichier de calibrage distorsion_ueye_640.cal il faut remplacer les points par des virgules (regler locale??) → c'est bon!

http://stackoverflow.com/questions/13489940/stupid-bug-with-fscanf-comma-instead-of-point

@user1773603 And probably broke everything else. The (almost) first line in any console application written in C++ should be std::locale::global( std::locale( “” ) );; in C, this would be setlocale( LC_ALL, “” );

NE MARCHE PAS!!!!

IL faut faire:

      std::setlocale(LC_ALL, "en_US.UTF-8");
