see PlayChessWithAWebCam
Motivation
See MagneticSensorChessBoard1987 for the initial project of 1987. Time has moved on and the goals of the 1987 project can be achieved with less hardware and software in a more convenient manner these days.
Usecases
Play Chess With A Webcam
As a chess player given a physical board and a starting position in FEN notation and a webcam observing the board in a proper angle (e.g. from above) i want to play moves against an opponent that
- might sit directly in front of me
- might sit with a similar setup remotely in front of a physical board
- might play using some other remote means of communication
so that my moves are recorded and transmitted with the option to
- later analyze
- immediately analyze and if allowed by the oponent take back moves
If the oponent is not at the board I'll have to do his moves manually or later might use some kind of robot to do that for me ...
Detecting Moves by a WebCAM
As a chess player given a logical chess board setting in FEN notation (e.g. starting FEN that I have setup on my physical board being observed by a webcam in HD at e.g. 25 FPS I want to use a webcam to detect my next valid move e.g. e2-e4 so that the logical board changes to the new FEN e.g. (https://lichess.org/editor/rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR_w_KQkq_-) and the move is available in Algebraic_Notation e.g. e2-e4 e.g. to be transferred via Universal_Chess_Interface or e.g. lichess.org
Process Chessgame webcam movie recording to create PGN
As a chess player
I want to process a given movie of a chessgame so that I get a Portable Game Notation of the game's moves
see
https://chess.stackexchange.com/questions/4695/tools-for-automated-notation-webcam-movie-to-pgn/4699
State of Project
As of 2019-12-28 version 0.0.1 has not been released yet. The state of the project is alpha and will be in beta in a few days.
There is already a lof of stuff to try out and to participate in this open source project.
There is a web frontend which you can try out. Sample videos are available at https://github.com/SteinscheisserKarl/Chess-Testmedia/ which you can check out with:
sudo apt-get install git-lfs
git clone https://github.com/SteinscheisserKarl/Chess-Testmedia/
cd Chess-Testmedia
git lfs install
git lfs pull
git clone https://github.com/WolfgangFahl/play-chess-with-a-webcam
cd play-chess-with-a-webcam
scripts/install
scripts/run --input ../Chess-Testmedia/TK_scholarsmate30.avi --event 'PlayChessWithaWebCam' --site 'Stuttgart-Germany' --black OTB1 --white OTB2 --round 1 --warp '[[81,18],[271,15],[268,203],[85,203]]' --rotation 90 --nomoves
to tryout one of the Scholars Mate example video's in command line mode
or
scripts/runweb
for the default web cam or
scripts/runweb --input 1
if there is a second webcam installed.
You might want to click the corners of your chessboard to try out the warp function manually or click the .
The scripts:
- still
- record
are already useful for taking pictures and movie recordings of your chess match. The detection of the board and moves is not fully operational yet.
If you'd like to experiment a bit you can run the tests which will show some debug output.

Test
if you run into the ImportError: libcblas.so.3: cannot open shared object file: No such file or directory error you might want to run both lines otherwise simply try the test script itself
pip3 install opencv-python; sudo apt-get install -y libcblas-dev libhdf5-dev libhdf5-serial-dev libatlas-base-dev libjasper-dev libqtgui4 libqt4-test

ImportError: numpy.core.multiarray failed to import
The issue is that this project needs Python3.7 to work which can only be installed manually by compiling on stretch at this time (which i didn't try out ...)
Windows 7/10
- Download Python 3.7.3 from https://www.python.org/downloads/release/python-373/
Alternative: Install via Linux Subsystem
This installation uses a "hybrid approach" - we install the web elements e.g. javascript/css/fonts via bash script and then use the Windows native python and pip to proceed.
- see https://docs.microsoft.com/de-de/windows/wsl/install-win10 with Ubuntu from the Microsoft Store
then follow the linux instructions
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install xdg-utils
Access files via Z:
cd pcwawc
pip install -r requirements.txt
cd ..
set PYTHONPATH=.;%PYTHONPATH%;
