dataArtist - …scientific data processing made easy.
Download for Windows 7-10
dataArtist is a graphical program for interactive data analysis and
processing. It is currently specialized image processing tasks in
combination with electroluminescence imaging of photovoltaic devices.
It is written in Python (2.7) and is released under open source.
dataArtist is written to be platform independent. It is known to run
under Windows 7-10 and Ubuntu Linux 14.10 (soon).
Please cite *dataArtist* as follows:

Camera Calibration and Image Correction”, Proc. 43rd IEEE Photovoltaic Specialists Conference, Portland, 2016.
General usage, camera calibration and image correction are explained
in youtube screencast sessions, see
Supported file types
Data is imported through drag n’drop.
- Common used (TIF, BMP, PNG, JPG, CSV, TXT, MAT)
- RAW, if data type and image shape are known
- Numpy arrays
a) Portable version
- dataArtist runs out of the box. No installation needed (currently
Windows only). See section Releases.
b) Installation into existing Python installation using pip
After installing Python2.7 and ensuring that ‘pip’ is a recognised command in the command shell (Windows: CMD.exe).
you need to install the following packages BEFORE installing dataArtist:
- OPTIONAL: RabbitMQ (for inter-program communication)
Please refer to the USER manual for more information.
Once these packages are installed, open a command shell and type:
pip install dataArtist
- Now start dataArtist from the command shell:
- To launch dataArtist into the system tray type:
- To open a dataArtist session directly type:
dataArtist -o /path/to/my/session.da
Scripting, Automation, Modding
dataArtist comes with a built-in python shell. Data can be examplary
accessed though d1.l3 (display 1, data layer 3) and tools
e.g. through d.tools['Axes'].click() (in current display execute
dataArtist allows adding own tools, displays and importers, for
examples, see dataArtist/modding.

Example: Electroluminescence imaging
For camera calibration all needed images are dropped into dataArtist
and the matching tool is executed. The calibration results are
hereinafter saved to a calibration file. The determination of the
point spread function is exemplary shown in the following figure:

determination; b: noise-level-function measurement; c: Dark
current mapping; d: Flat field mapping; e: PSF estimation
(selected): f: lens distortion measurement
The correction of EL image is shown in the following figure.
Perspective correction (red box) can be done either using the outline
of the PV device (automatically detected or manually defined) or using
a reference image.
