Live Capture

Calibrated movement analysis

Ready for calibration

Start the camera, capture 10–15 checkerboard views, then run intrinsic calibration. After that, capture the board once at the movement plane for millimetre mapping.

No calibration views captured.

Movement-plane mapping

Capture the same checkerboard once at the exact movement plane. This creates an image→millimetre homography for planar measurements.

Plane map not set.
