MVTec make camera calibration easier

Accurate camera calibration, 3D positioning and orientation
Camera calibration is a critical task for obtaining accurate real-world measurements in machine vision applications.

With the release of HALCON 12, MVTec introduces a new, redesigned calibration target that eases the process significantly.

New plate's benefits

•

 More calibration marks providing better radial lens distortion correction with fewer images
• multiple unique finder patterns embedded within the hexagonal mark array
• Because only one finder pattern needs to be visible in the image for calibration, the entire field of view can be covered with calibration marks
• Fewer images needed for 3D calibration while giving same level of accuracy as the old method
   
Additonal benefits
Having multiple unique finder patterns allows images from multiple cameras observing different portions of the same plate to be mapped into the same world coordinate system. This enables the performing of calibrated image stitching without the need for a custom fixture to hold several targets at precisely-known distances.

The new calibration targets are offered in several different sizes ranging from 20mm x 15mm up to 320mm x 240mm.

HALCON 12 continues to support the old calibration target, and as with previous versions of HALCON, it is still possible to print your own plates for testing purposes. Printed targets should not be used for high-accuracy applications, however.
