You need to perform calibration in order to ensure the work of the scanner after the adjustment of lenses. Scanning software analyses the image of the plate, obtained from the cameras and compares it with the mathematical model, marked by the algorithm.

There are 2 types of calibration: Calibration by default scheme (8 steps), calibration by alternative scheme (11 steps). Also, when using a rotary table, the procedure of evaluation of the axis of rotation is carried out.

Сalibration is used if:

• the lenses of the cameras need to be reconfigured (for example, if you change the scanning area),
• if you suspect that scanning accuracy got worse,
• after transporting the scanning complex.

Axis evaluation of rotary table is performed:

• in case of any change in the position of the rotary table to the scanner (when scanning on the rotary table).

Calibration of rotary table is described in the Scanning on rotary table section.

ScanCenter NG 2022.1.1 has a new hardware profile storage system based on scanner model identification recorded on the license key.

In the new version, hardware settings and calibration for several scanners of the same model are stored in different folders.

When migrating to a new version, the user's scanner configuration settings will be reset to default, so a new calibration will be required.
