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 2019-10-21 version 0.0.1 has not been release yet. The state of the project is development/alpha.

There is already a lof of stuff to try out and to participate in this open source project.

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.

opencv tutorial stuff

Also in the opencvtutoral directory you'll find:

• colorcluster.py
• histogramm.py
• hough_lines.py

hough lines

histogramm / colorcluster

Clusterization took 2.8 s for 1 channels
Clusterization took 4.5 s for 2 channels
Clusterization took 6.7 s for 3 channels
