3D Camera Calibration

An explicit and precise description of your area or line scan setup, even for complex distortions: A small set of internal and external camera parameters map the image coordinates to real world coordinates permitting, for example, subpixel-accurate measurements up to 1 µm in a field of view of 10 mm - also with line scan cameras. Crucial for robotic applications is HALCON's hand-eyecalibration.

Note that you can buy high-precision calibration plates from MVTec.
