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.
State of Project
As of 2019-12-18 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 e.g. with:
scripts/install
scripts/runweb --input testMedia/scholarsmate.avi --debug --warp '[[140,7],[506,10],[507,378],[136,373]]' --rotation 270
to tryout the Scholars Mate example video
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.
Installation
