1. Chessboard Pattern
Use a standard chessboard pattern with known dimensions. The pattern should have alternating black and white squares.
Tip: Print the pattern on a flat, rigid surface for best results.
2. Capturing Images
- Capture images from different angles and distances
- Include images where the chessboard fills most of the frame
- Use at least 10-15 images for reliable calibration
- Avoid blurry images or extreme angles
3. Parameters
Inner Corners: Number of internal corners (intersections) in the chessboard pattern.
Square Size: Physical size of each square in millimeters.
Best Practices
For best results, use a well-lit environment and ensure the chessboard is flat in all images. The more varied your images are in terms of angles and positions, the better your calibration will be.
