About OpenNI
OpenNI has shown some lights to natural interactions by using depth map images together with RGB images from cameras. Natural human gestures, e.g. hand moving, limbs movements are all being developed fast. Microsoft Kinect is a typical example that demonstrated the huge potential of the OpenNI in terms of game applications. While, more work could be done with OpenNI, with other devices that could capture depth images, e.g. ASUS’s Xtion pro. In the OpenNI community supported by manufacturers e.g. Primesense, Microsoft and Asus more information could be found in openni.org.

The last tutorial about installing opencv in ubuntu with pandaboard 4 – compiling the opencv 2.3.1 did not complete the final compile steps, this post aims to complete that.
Continue the compiling of openCV 2.3.1
I assume you have finished the openCV compiling using cmake ., make, and make install commands in the terminal. Bear in my mind there is one thing I need to remind – be aware of the system date and time, as I left that incorrect and made some unnecessary compiling mistakes.

Before the compiling
I was about to write a post about compiling the newest openCV 2.3.1 in Ubuntu with pandaboard, but because of the proxy network problem in Ubuntu software update and the right solution to the proxy network settings, this post was postponed.

The problem is relevant to software updates and installations in Ubuntu, before and after openCV installation. There were two general suggestions made in the previous post – finding a new network environment, or, properly setting up the proxy parameters.

How to install openCV in Ubuntu without networks
In the last post of installing openCV in Ubuntu with pandaboard, the failure of software update of openCV was discussed. But if there was no alternative to switch to other working networks, then the only way to install openCV in Ubuntu is as the way showed in this post.
- first, downloading the OpenCV-2.3.1a.tar.bz2 from openCV wiki, selecting ‘other announcements’ then going to ‘for mac and linux’, the page will be directed to sourceforge in this page: http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/.

OpenCV at ubuntu with pandaboard
At the first beginning of post, I would like to remind a tiny, but sometimes may huge, problem in installing openCV at ubuntu with pandaboard – the network proxy setting. This tiny issue could be the fatal problem when it was not aware of. I had tried hundreds of times to ‘apt-get update’ but nothing worked out. After I searched the problem of ‘failed to fetch…’, I was not well informed about how severe that problem was. Until I tied to change the Ubuntu Software Center’s networking settings, I noticed there was an tap used for networking proxy purposes.
