This documentation applies for users of LPVR with ART tracking. If you are using Optitrack, please refer to this page for manual calibration instructions. Besides the pre-defined marker files we also offer an automatic calibration procedure that you can use to create your own body file. Please see here for instructions. |

On this page we show a number of predefined marker setups for optical marker target. These files have been created using our automatic calibration algorithm or data from the manufacturer and are a very close approximation of an ideal configuration.
