Can I use another target for calibration?


Reikan FoCal is optimised to work with a specific target design, you can however use any target with appropriate setting applied and cautions noted.

We very much recommend using the FoCal designed target, it provides extra features such as target validation and accounts for target/camera movement during calibration and testing.

An ideal user chosen target should have well designed, sharp high contrast edges in both horizontal and vertical axis. Some caution is advised, since user chosen targets can vary widely results may also vary depending on target chosen.

To use a different target change Preferences > Tests (tab) > Target Validation to "No Target Validation".
