Vision: OpenCV and PCL

OpenCV

OpenCV is an open-source library that includes many computer vision algorithms for 2D images, such as object detection or other image processing functionalities.

PCL

The Point Cloud Library (PCL) is an open-source library for processing point clouds. The library provides many algorithms for filtering, feature estimation, registration, model fitting, or segmentation.

Installation

OpenCV

Install Python-OpenCV from the Ubuntu repository by

command-line

 sudo apt-get update
 sudo apt-get install libopencv-dev python-opencv

PCL

PCL can be installed through PPA

command-line

 sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
 sudo apt-get update
 sudo apt-get install libpcl1.7 pcl-tools

Note that PCL currently supports only C++. There exist a set of Python bindings, but they provide very few functionalities.

The above instructions will probably not install the latest version of OpenCV and PCL. To get newer version of these libraries, consider installing from source.
