Quick Calibration

With calibration, the scanner parameters are recalculated, which not only ensures the accuracy of the scanner, but also improves the quality of scanning. Thus, it is recommended that you calibrate the device before each use.

Calibration is required under the following conditions:

  • When the scanner is used for the first time or there are more than 7 days since last calibration.

  • The scanner was severely shaken or shocked, such as shocked during transportation.

  • Severe accuracy reduction, such as frequent errors in alignment or unrecognized markers.

  • Incomplete data is acquired during the scanning or serious deterioration of the quality of scanned data.

Note
  • After completing calibration, this step will be automatically skipped when you start up this software again.
  • If the current device has not been calibrated for more than 14 days, a yellow exclamation mark will appear next to the calibration step button in the navigation bar. If it has been more than 20 days without calibration, a pop-up window will appear on this interface with the option to Calibrate now or set a reminder for 7 days later.
Warning

  • The calibration board is matched to the device. Doing the calibration with an incorrect calibration board will fail to generate good scan data or optimum accuracy.

  • Always make sure that both sides of the calibration board are clean and free of scratches.

  • Do not place heavy objects or sundries on the calibration board.

  • Keep the calibration board away from corrosives, metals and sharp objects to avoid corrosion or damage.

  • It is not recommended that you wipe the calibration board. When cleaning the board becomes very necessary, gently wipe it with a piece of a clean damp cloth. Do not use a cloth with chemicals or alcohols to wipe the calibration board.

  • After using the calibration board, put it safely in a box or flannel bag.

Specific calibration steps are shown as follows:

During the calibration process, please follow the software guide to hold the device in five different angles and capture five images.

1.Place the calibration board with the front side (white background with black dots) facing up, flat on the table.

2.After picking up the scanner, move it above the calibration board. The scanner should be positioned vertically, facing directly towards the table, in the same direction as shown in the figure. Ensure that the blue circle (indicating the scanner's focus) is positioned within the grey circle (indicating the center of the calibration board) and turns green in the software.

3.Press on the back side of the scanner to start collecting images.

4.During the data collection process, you need to move the scanner up and down (ensuring that the projected circle remains green) until the distance indicator on the software interface shows all green. Once the data collection is complete, the software will automatically exit the data collection mode, proceed to the next stage.

Note

During the collection process, if the interface prompts "Please ensure the target circle green," you need to adjust the angle of the handheld device; if the interface prompts "Too close," you need to pull the scanner away; if the interface prompts "Too far," you need to push the scanner closer.

5.Please continue to follow the instructions provided by the software to complete the subsequent steps.

Warning

You need to press button on the back side of the device again to start collecting the image for the new position.

6.Check the calibration result, click Next to enter the White Balance step.

Note

  • If the calibration fails, please click Redo calibration.
  • If you cannot get the pass result anyway, please contact your supplier or our support team.
