Calibration Operation

The calibration process includes three types of calibration: laser calibration, infrared calibration, and white balance calibration. Laser and infrared calibration are compulsory steps, while white balance calibration is optional. You can complete the corresponding calibration based on your needs.

Calibration Entrance

You can enter the calibration process in the following two ways:

• In the Control Center or User Center, tap and select Camera or White Balance Calibration to start.
• In the status bar at the top of the interface, tap the calibration warning and select Camera or White Balance Calibration to start.

Laser Calibration

A calibration process requires completing the calibration at all angles and distances according to the illustrations.

Note

• Before the first calibration or after changing the calibration board, please first go to Settings > Calibration interface to bind the calibration board before starting calibration.
• Upon first entering the calibration process, you will automatically enter the help interface before calibration, where you can view guidance related to calibration; at the last step of the help interface, tap Start to enter the formal calibration process.
• During the calibration process, tap to re-enter the help interface; tap to exit the calibration process.

Taking laser calibration as an example, the calibration steps are as follows:

Caution

• Do not perform calibration on reflective tile floors.
• Do not perform calibration in environments with cluttered markers.

1. Please place the calibration board with the marked side facing up on the flat surface.
2. Align the red crosshair of the scanner with the white crosshair on the calibration board; when the two crosshairs overlap, the crosshair will turn green.

3. Move the scanner vertically up and down until the blue area on the screen is completely eliminated.

   Caution

   • When moving the scanner up and down, please ensure:

     • The center of the scanner remains aligned with the center of the calibration board.
     • The scanner remains parallel to the plane where the calibration board is located.

   • If you are unable to eliminate the blue area completely while moving the scanner up and down, try adjusting the camera brightness using the brightness slider on the left side.

4. Place the calibration board on the holder as shown.

5. Repeat steps 2 to 3 to complete the calibration for that direction.
6. Rotate the calibration board as shown, and repeat steps 2 to 3 to complete the calibration for other directions.
7. After completing calibration for all directions, a calibration file will be automatically generated.
8. If the calibration is successful, you can exit calibration and proceed to scanning; if the calibration fails, please recalibrate.

Note

• After calibration is complete, please store the calibration board properly for future use.
• If calibration fails multiple times, please promptly contact technical support and provide the error code.

White Balance Calibration

Note

White balance calibration is an optional calibration step. It can be performed when there is a discrepancy between the scanned texture data and the actual texture of the object.

Steps

1. Please place the calibration board with the white side facing up on a flat surface.
2. Aim the scanner at the calibration board.
3. Move the scanner vertically up and down until the white circle on the screen completely overlaps with the blue circle.
4. After successful calibration, you can exit calibration and proceed to scanning; if calibration fails, please recalibrate.

Note

• After calibration is complete, please store the calibration board properly for future use.
• If calibration fails multiple times, please promptly contact technical support and provide the error code.
