PuzzleBoard - Adding Lightweight Position Encoding to Checkerboard Targets

This video demonstrates the PuzzleBoard calibration target — a pattern that combines checkerboard structure with lightweight positional encoding. Each section of the board is uniquely identifiable, even at low resolution or when only partially visible. For calibration accuracy, PuzzleBoard targets should be printed on a rigid substrate rather than paper.

Non-Repeating Geometry for Robust Camera Calibration

PuzzleBoard calibration targets are designed for high-accuracy camera calibration where traditional checkerboards and repeating patterns introduce ambiguity.

By using non-repeating, puzzle-like geometry, each feature on the board is uniquely identifiable — enabling reliable calibration even when the target is partially visible, viewed at steep angles, or used across multi-camera systems.

Integrated directly into FoamCorePrint’s online Pattern Generator, PuzzleBoard allows you to design and print a custom calibration target on the substrate of your choice.

Each feature is geometrically unique, eliminating false matches common with repeating patterns.

Works When the Full Board Isn’t Visible

PuzzleBoard remains effective when the board is cropped, rotated, or captured at extreme angles.

More Reliable Calibration Results

Unique feature correspondence improves intrinsic and extrinsic calibration stability.

Scales Cleanly to Large Boards

PuzzleBoard maintains accuracy at larger physical sizes without introducing repetitive artifacts.

Helpful Ordering Tips When Uploading Your Own Designs

These tips will help you through checkout and ensure your targets deliver the best results!

  1. Always submit full-scale 1:1 files and adjust the product dimensions to match your file size If necessary, use decimals (this will avoid unwanted scaling).

  2. Upload vector PDF or AI file format in CMYK color mode for optimal print results.

  3. Double-check to compare your file size to each product size during the proofing process. Make sure they are 1:1. If they are not, you can either remove the files and reupload the corrected versions or update the product finish size to match the file size (repeat step one).

  4. FoamCorePrint is not responsible for incorrect patterns or finished product sizes due to improper scaling of customer-submitted artworks.

  5. Submit your files for review - We encourage first-time customers to contact our customer support to review all print files before placing orders via live chat or email.

Detection Under Partial Occlusion

Seeing PuzzleBoard in Action

This demonstration shows PuzzleBoard detection remaining stable even when the calibration target is partially occluded by a moving object. Because each region of the pattern is uniquely identifiable, detection can continue without requiring a fully unobstructed view.

This capability is especially valuable in robotics, multi-camera systems, motion capture environments, and other dynamic scenes where occlusion is unavoidable.

What Is a PuzzleBoard Calibration Target?

A PuzzleBoard is a planar calibration target composed of uniquely shaped, non-periodic features. Because the geometry does not repeat, calibration algorithms can resolve correspondences more reliably — even when only a portion of the board is visible.

Software Compatibility & Usage Notes

PuzzleBoard calibration targets are designed to integrate into a wide range of computer vision and camera calibration workflows.

PuzzleBoard patterns can be used with:

  • Custom OpenCV-based calibration pipelines
  • Robotics and SLAM systems
  • Multi-camera and stereo calibration setups
  • Machine vision and research applications

Because PuzzleBoard uses non-repeating geometry with positional encoding, detection and decoding depend on the specific calibration or feature-detection implementation being used. Some environments may require custom detection logic or configuration to fully leverage the pattern’s unique properties.

For accurate calibration results:

  • The target should be printed on a rigid, dimensionally stable substrate
  • The board should remain flat and stationary during capture
  • Multiple views from varied angles and distances are recommended

If you have questions about compatibility with a specific software stack or calibration workflow, our team is happy to help.

Frequently asked Questions

FAQ

What makes a PuzzleBoard calibration target different from a checkerboard?

PuzzleBoard patterns use non-repeating, uniquely identifiable features so that calibration software can recognize portions of the target even if the whole board isn’t visible. Traditional checkerboards rely on repeating corners and typically require the entire pattern in view for accurate detection, which can limit calibration in partial-visibility or wide-FOV setups.

Do I need special software to use a PuzzleBoard pattern?

PuzzleBoard targets can be used with most standard camera calibration tools and libraries (e.g., OpenCV, MATLAB), just like checkerboards or Charuco boards — as long as the software can detect grid features. However, detection performance and compatibility depend on your specific calibration implementation. If you have a custom calibration pipeline, be sure it supports the type of pattern feature points you generate.

Can PuzzleBoard calibration targets be used if only part of the board is visible?

Yes. One of the key advantages of PuzzleBoard is that even small image sections are unique, allowing calibration software to identify the pattern and position without needing the full board in view. This helps in environments where full visibility is difficult to achieve.

What sizes should I choose for my calibration board?

You should size the calibration target so that it fills most of your camera’s field of view (FOV) during calibration — this typically yields better estimation of lens parameters and distortion, especially at the image edges. Small boards that fill only a fraction of the view tend to produce less constrained solutions.

Can I upload my own PuzzleBoard pattern file to print?

Yes. You can upload your own vector pattern (e.g., SVG, PDF) into the pricing tool. Enter the final board dimensions in inches (up to three decimal places), then click “Get Started” to upload and preview your design. Your uploaded pattern will be printed at true 1:1 scale. (Proofs are for layout reference and may not reflect final print appearance.)

Is a PuzzleBoard suitable for multi-camera or stereo calibration?

PuzzleBoard targets can be very effective for multi-camera calibration because the unique feature layout helps with correspondence and reduces ambiguities across different viewpoints. Always ensure that your calibration software supports the pattern type you’re using for best results.

What software libraries support camera calibration targets like PuzzleBoard?

Common tools that support planar calibration targets include:  OpenCV (widely used in robotics and machine vision)  MATLAB Computer Vision Toolbox  Various photogrammetry and SLAM packages  Many libraries include built-in support for checkerboards, Charuco, and AprilGrid patterns; custom decoders or feature detectors may be needed to extract PuzzleBoard features reliably.

How many images should I capture for accurate calibration?

For reliable calibration results, it’s generally recommended to capture multiple images from varied angles and distances, ensuring the target fills the view. This helps the algorithm constrain intrinsic parameters (like focal length and distortion) more effectively. (Standard practice suggests capturing at least 10–15 diverse frames.)

Can PuzzleBoard targets also be used for camera pose estimation or tracking?

Yes. PuzzleBoard can also support pose estimation and marker-based object localization because its pattern encodes unique positional information that can be decoded even in low resolution.

What are some tips for Better Calibration?

  1. Use good lighting and place the board flat and stable in the scene.  
  2. Capture frames with significant variation in angle and distance.  
  3. Ensure the board fills most of the camera’s FOV.
