Comment installer opencv dans Ubuntu 12.04 et l'exécuter avec Python?
Je voudrais faire le traitement d'image sur framboise-pi.
Pour cela, je veux d’abord le faire sous Ubuntu.
Quand je lance la commande Sudo apt-get install libopencv-dev. J'ai la sortie suivante:
naveen@ubuntu:~$ Sudo apt-get install libopencv-dev

Y a-t-il quelque chose que je puisse faire pour résoudre l'erreur?
Beaucoup de gens ont du mal à installer OpenCV. Il existe un simple fichier de script .sh qui permet de récupérer tous les fichiers de dépendance sur Internet et de compiler le code source, puis d'installer opencv sur votre système.
Téléchargez le dernier opencv.sh de ici
Je suppose que comme vous m'avez dit que vous avez téléchargé le script dans le répertoire de téléchargement, procédez comme suit:
Terminal ouvert.
cd ~/Downloads
chmod +x opencv.sh
./opencv.sh
Voir le documentation Ubunt pour plus d'informations
