Are you a chess enthusiast who wants to bring together the tactile experience of a real chessboard with the convenience of online play? This guide will walk you through the setup and usage of a program that allows you to play online chess using a physical chessboard and a webcam, utilizing computer vision technology to detect your moves.

Setup

To get started, follow these simple steps to ensure that your setup is ready to go:

1. Turn off all animations and extra features in the online chess game for a simplified chess board experience. (You can skip this step if you enter your Lichess API Access Token.)
2. Take screenshots of the chess board positions: one for playing white and another for black. Save these images as white.JPG and black.JPG.
3. In the settings of the online game, enable auto-promotion to queen. (This can be skipped if you enter your Lichess API Access Token.)
4. Place your webcam near your chessboard, ensuring it captures all squares and pieces visibly.
5. Clear all pieces from your chessboard and run board_calibration.py (or use the Board Calibration button in the GUI).
6. Verify that the corners of your chessboard have been detected correctly by the board_calibration.py program, and press the key q to save the corners. You can adjust by pressing r to rotate the image if needed.
7. Note that a constants.bin file will be created or modified during this process.

Usage

Now that your setup is complete, follow these steps to use the program:

1. Place the pieces on the chessboard to their starting positions.
2. Start your online game.
3. Run main.py (or click the Start Game button in the GUI).
4. Switch to the online game window (you have 5 seconds) to allow the program to detect the chessboard.
5. Wait until the program indicates that the game has started.
6. Make a move if it’s your turn; if it’s your opponent’s turn, the program will simulate their move automatically.
7. Continue playing, repeating from step 6.

Understanding the Code: The Chessboard Detective Analogy

Imagine your chessboard is a bustling city, and each square is a unique street corner. The webcam acts as a helicopter hovering above this city. As you make moves, the helicopter observes changes in the city landscape. The program is like a city planner that translates these changes into actions—or mouse clicks—at the online game level. With each turn, the city planner watches for newly constructed buildings (pieces moving) and adjusts the plans for how to interact with the cities (your online chess game) accordingly.

Graphical User Interface (GUI)

You can run gui.py to access a user-friendly interface for the setup and usage steps. The GUI allows you to easily customize your experience and manage your preferences.

Troubleshooting

If you encounter any issues while utilizing the program, try the following troubleshooting tips:

• Move Registration Failed: If you receive an error indicating “Move registration failed,” it may be due to incorrect board calibration or the color of your pieces being too similar to the square colors. Verify your calibration and enhance the contrast between your pieces and the board.
• Slow Corner Detection: If the program is taking too long to detect corners, adjust the webcam’s position for better visibility. Elevate or lower it to give a clearer view of the chessboard.
