Untuk yang berexperimen dengan Computer Vision. OpenCV menjadi library programming yang handal. Namun untuk installasinya cukup sulit karena OpenCV di desain agar bisa berjalan di berbagai mesin dan keperluan. Untuk pemula atau yang ingin coba-coba dengan OpenCV, installasi ke komputer cukup sulit dengan berbagai prosedurnya karena OpenCV berupa source code. Untuk itu saya membagikan script sederhana untuk installasi standar. Di sini saya membagikan script installasi untuk distro Ubuntu dan derivative-nya. Script ini juga bisa digunakan pada Fedora, CentOS dan turunan RHEL lain. Untuk distro lain atau memerlukan config lebih advanced bisa anda edit sendiri sesuai keperluan.
Script berikut akan mendownload OpenCV versi terbaru dan menginstallnya ke dalam komputer anda. Anda akan melihat beberapa komfirmasi untuk download. Anda juga bisa mendownload versi OpenCV lainnya saat konfirmasi. Jika anda sudah mendownload di directory yang sama, maka script berikut langsung menginstall tanpa mendownload.
Berikut shellscript yang saya buat untuk installasi :
