[Casper Cartridge Top]

Abstract

You are assumed to have a bootable USB memory stick of Ubuntu 10.04.1 LTS.

Basic Setup

1. Time zone
   [Menu] System - Administration - Time and Date
   Then, Time zone : Asia/Tokyo (or where you live).
   
   
2. System clock
   If you set your local time to PC's system clock and you want to use that on Ubuntu too, turn off the UTC flag.
   

   $ sudo gedit /etc/default/rcS

   And then change "UTC=yes" to "UTC=no".
   
   
3. Emacs
   If you are going to install emacs, you can suppress error messages by:

   $ sudo gedit /usr/share/themes/Ambiance/gtk-2.0/gtkrc

   And then change "GtkRange::trough-under-steppers = 0" to "GtkRange::trough-under-steppers = 1".
   
   

Compile OpenCV 2.1.0

1. Preparation
   Some (freeglut3, dc1394, emacs) are not mandatory, but I recommend you to have these.
   (If you seem to fail installing some packages, try "apt-get update" to catch up recent changes.)
   

   $ sudo apt-get install freeglut3-dev $ sudo apt-get install libdc1394-22-dev $ sudo apt-get install cmake g++ libavformat-dev libswscale-dev $ sudo apt-get update $ sudo apt-get install libgtk2.0-dev $ sudo apt-get install emacs

2. Download OpenCV
   From OpenCV web site, download OpenCV-2.1.0.tar.bz2 .
   Suppose you put that at your home, "/home/ubuntu".
   
   
3. Exract OpenCV
   

   $ cd $ tar xvfj OpenCV-2.1.0.tar.bz2

   
   
4. Quick-fix of SURF-zero-bug
   SURF of OpenCV 2.1.0 sometims fails (dump) when there is few textures. It is reported as a bug, so fix that in quick way.

   $ cd [Download SURF-BUG-fixed cvsurf.cpp (cvsurf-by-kameda.cpp)] $ mv OpenCV-2.1.0/src/cv/cvsurf.cpp OpenCV-2.1.0/src/cv/cvsurf.cpp-zerobug $ cp cvsurf-by-kameda.cpp OpenCV-2.1.0/src/cv/cvsurf.cpp

5. Prepare building-directory of OpenCV
   You can compile OpenCV source tree at different directoy by using cmake.

   $ cd $ mkdir OpenCV-2.1.0-build $ cd OpenCV-2.1.0-build

   
   
6. Compile OpenCV
   Now it sholuld be easy.

   $ cd $ cd OpenCV-2.1.0-build $ cmake ../OpenCV-2.1.0 $ make $ sudo make install $ sudo ldconfig

   
   
7. All set!
   You may reboot the system and enjoy!
