Wide-angle cameras are excellent for covering large interactive surfaces, but they come with a common trade-off: geometric distortion. Straight lines bend, the image geometry changes across the frame, and tracking accuracy can suffer - especially near the edges.
To solve this, we’ve added a new module to Motioncube: Lens Calibrator.
What Lens Calibrator does
Lens Calibrator performs camera calibration and image undistortion to correct wide-angle lens deformation. The calibration is based on standard checkerboard calibration patterns, aligned with modern best practices in camera calibration.
Fully automatic workflow (built for non-technical users)
We designed the process to be as frictionless as possible:
- automatic frame scanning
- checkerboard detection
- calibration error estimation
- best-frame selection
- calibration parameters computation
- undistortion applied to the live camera image
The result is a calibrated camera view that’s ready to use in your Motioncube setup.
Why it matters for interactive installations
Correct geometry means more reliable tracking - which translates directly into better performance for:
- fast ball tracking on interactive walls
- interactive pen detection
- finger touch interaction
Lens Calibrator is fully integrated in Motioncube, so you can test and onboard new camera models faster and deploy with more confidence.
