OpenPTV-Python (PyPTV)

OpenPTV-Python (a.k.a PyPTV) is the Python version of OpenPTV. It is basically the Python Traits GUI (from Enthought Inc.) that interfaces the OpenPTV library that includes all the core algorithms (correspondence, tracking, calibration, etc.) written in ANSI C.

Both PyPTV and the OpenPTV library are in the development phase and continuously refactored. Please follow the development on the community mailing list:

Installation

Mac OS X users can use the pre-compiled try-before-installing instructions

Prerequisites:

  1. [Optional, recommended] Download and install the unit testing framework http://check.sourceforge.net/ - without this one you cannot test the compilation properly, although you can install and run the PyPTV software.

  2. Install the OpenPTV library (liboptv) from source: https://github.com/openptv/openptv/. Please follow closely the Installation instructions.

    • If you are not interested in development, download the appropriate pre-compiled library files: liboptv installers. The include folder content should be copied/installed to something like /usr/local/include and the lib content into /usr/local/lib. Otherwise add the location of the liboptv files in the next step, e.g. python setup.py install -I /usr/local/include -L /usr/local/lib

  3. Get one of the Python development environments for your platform. We recommend WinPython or PythonXY on Windows or Enthought Python Distribution on all the platforms. If you want to build all the prerequisities yourself (e.g. using Linux package manager, apt-get or Mac OS X homebrew or ports) then you need Python 2.7, Cython, Numpy, Scipy, Matplotlib, ETS tools (TraitsUI, Chaco, Enable and many sub-packages)

  4. Download or clone the PyPTV repository: http://github.com/openptv/openptv-python.

  • If you don't want to test, skip this step, proceed to PyPTV installation:

  • If you want to run the tests: use the same set of autotools. On Mac OS X you might need to add CC="gcc -arch i386" to the ./configure command.

     	autoreconf --install
 	./configure
 	make
 	make check

Install PyPTV:

Install by compiling the Python/Cython interface to the liboptv library (unrelated to the tests in the previous step) and install it to the default locations:

	cd pyptv_gui
	python setup.py install

or if you don't want to install somewhere in the path, compile all the necessary libraries in the ../src_c directory

	python setup.py build_ext --inplace

if the setup process creates errors related to liboptv linking, please add the /include and /lib locations, e.g.:

	python setup.py install -I /usr/local/include -L /usr/local/lib

Getting started:

If the compilation passed, open the terminal and run:

	python pyptv_gui/pyptv_gui.py
