Pre-Scan Settings¶
After entering the scan preview interface, you can adjust scanning settings for the current project.
Note
After start scanning, you can adjust the camera view or switch between data quality indicator and texture display, but you could not readjust the advanced settings.
Camera View¶
Tap
to enable camera view, it will show the black-and-white camera view and texture camera view (only shown when Acquire Texture is enabled).
- Black-and-white camera:
Auto-brightness is enabled by default (only supported for the fast scan mode), and you can tap that button in the upper right corner to switch to
manual mode, then you can tap on the upper part of the window to increase the brightness (up to 8), or tap on the lower part to decrease the brightness (down to 1).- The red points in the camera view indicate over-exposure points. To improve scan quality, it is recommended that you lower down the camera brightness when there are large areas of red over-exposure points, or increase the camera brightness when the camera view is too dark, until the brightness is proper, as shown in the figures below.

If you are not satisfied with the scanned texture, you can adjust settings as follows:
- Texture camera:
- For adjusting the white balance: It is recommended that you first point the camera towards a white paper, a white wall or a white area on the calibration board before performing white balance calculation, then tap
to automatically calibrate the white balance; please hold the scanner still when it counts down from 3 to 1. - When the environment light is too bright, you can useCamera light adjustment (enabled by default), then you can tap on the lower part of the window to decrease the brightness (down to 1), or tap on the upper part to increase the brightness (up to 10).
- When the environment light is too dark, you can tap
to switch to the LED light adjustment (set as off by default), then you can tap on the upper part or lower part of the window to manually adjust the brightness (0 ~ 5, 0 indicates the LED light is off), and when the brightness is above 0, the button status will be shown as
.
- For adjusting the white balance: It is recommended that you first point the camera towards a white paper, a white wall or a white area on the calibration board before performing white balance calculation, then tap
Note
If it prompts that "
Unable to collect data", please adjust the distance of the scanner and the camera exposure status.
Scanning Distance (DOF)¶
Tap
to enable the function for adjusting the scanning distance, and an arc slider and scan distance numerical prompt will appear:
● Drag the slider to adjust the scanning distance; the image outside the DOF range will not be generated into 3D data.
● Tap
on the left side to exit this adjusting.
Data Display Mode¶
Tap 
to expand the list, and you can choose a data display mode:
: Data Quality Indicator; enabled by default for non-texture scanning objects.
: Texture Display; enabled by default when you choose Acquire Texture in 
Advanced Settings.
Note
You can enable only one of these two display modes; indicates that both modes are disabled.
Advanced Settings¶
Tap
in the right-side function bar to open the Advanced Settings window, where you can preset the scanned model as Object or Portrait, and the corresponding Scan Configuration and Align Mode:
The introduction to different align modes:
- Feature alignment: It is suitable for objects that cannot place markers and have rich surface features. It automatically completes the alignment by the surface geometric features of the object to be scanned.
- Texture alignment: It is suitable for objects with rich texture patterns on the surface but lacking rich intricate geometric features. It utilizes the surface texture features of the scanned object to automatically complete the alignment and merging process.
- Markers alignment: It is suitable for objects with limited geometric features or for scenarios that require high accuracy. It automatically completes the alignment by using markers attached randomly to the flat surface of the scanned object.
- Scan Configuration > Acquire Texture: Disabled by default; if disabled, the texture alignment mode can not be used, and Texture overlay mode as well as texture mapping are also not available.
- Align Mode:
- Feature alignment: Enabled by default; if enabled,
will appear in the project information area in the upper left corner. - Texture alignment: Disabled by default; if enabled,
will appear in the project information area in the upper left corner. - Markers alignment: Disabled by default; if enabled,
will appear in the project information area in the upper left corner.
- Feature alignment: Enabled by default; if enabled,
Note
- At least one alignment mode should be chosen.
- It is NOT recommended that you enable the feature alignment mode and the texture alignment mode simultaneously, otherwise it may impact the FPS.
- For the HD scan mode, markers of 3 mm and 6 mm can be recognized; for the fast scan mode, only markers of 6 mm can be recognized.
- If you switch the HD scan mode with markers alignment to fast scan mode, other advanced settings other than the markers alignment mode will be disabled; for other circumstances, all settings will be remained.
- For the fast scan mode, the feature alignment mode and the markers alignment mode can not be enabled simultaneously.
- For the fast scan mode, when the markers alignment mode is enabled, the brightness for the black-and-white camera can only be adjusted manually, and camera exposure function can not be used.
- For the fast scan mode, when the markers alignment mode is enabled, please ensure that the scanner has sufficient power (above 30%) during the scanning process, otherwise the scan can not be performed.
- Scan Configuration
- Acquire Texture: Enabled by default, and Texture alignment mode can be enabled, and Texture overlay mode as well as texture mapping are also available.
- Acquire Texture: Enabled by default, and Texture alignment mode can be enabled, and
- Align Mode:
- Feature alignment: Enabled by default; if enabled, will appear in the project information area in the upper left corner.
- Texture alignment: Disabled by default; if enabled, will appear in the project information area in the upper left corner.
- Feature alignment: Enabled by default; if enabled,
Note
- At lease one alignment mode should be chosen.
- It is recommended that you only choose the feature alignment mode when scanning the face or body, and not choose the texture alignment mode at the same time.
- If you switch the object scan mode with markers alignment to portrait scan mode, the feature alignment mode will be enabled automatically.
