Project Alignment¶

On the scanning interface, tap to enter the project group. After selecting a project group with multiple sub-projects, you can use the project alignment function. This feature enables you to combine scan data from multiple project files within the current project group into a complete 3D model, enhancing the completeness of the scan data.

Note

Project alignment is supported only for project groups of version V1.2.1 and above.
Laser project groups require at least 2 projects with both point clouds and markers to use alignment.
Infrared project groups require at least 2 projects with point clouds to use alignment.

Tap to enter the project alignment interface, where you can use automatic feature alignment, automatic marker alignment, or manual marker alignment methods to align projects.

Function	Description
	Tap to view the tutorial.
	Tap to expand the alignment method list and enable or disable Automatic Alignment.
	Tap to expand the project list and switch projects in the fixed or floating window.
	Tap to swap the projects between the fixed and floating windows.
	Tap to enable texture display.
	Tap to zoom in on the current window.
	Tap this button to restore the model to its original size and center it on the screen.
	In the alignment interface, tap to view the alignment structure of the current project; tap to undo the latest alignment result. If there are multiple alignment layers, you can undo all alignment results by tapping this button multiple times.
	Tap to clear the currently selected projects for alignment on the interface.

Automatic Feature Alignment¶

Note

Automatic feature alignment only supports infrared projects.

Select the projects to be aligned in the fixed and floating windows respectively.
Note
- You can perform zooming, rotating, and other operations on the fixed and floating windows of the interface to view the selected data models.
- If you need to reselect projects, tap to expand the project list for selection and replacement, or tap to clear the currently selected projects on the interface and then reselect.
Tap Start Alignment to perform feature alignment.
Note
- In automatic feature alignment mode, markers will not be displayed even if the project contains them.
- If there are 3 or more projects in the project group, after alignment is completed, you can repeat the above steps until all projects are aligned.
- After completing the alignment, if you need to undo the alignment effect, select the aligned object in the project group and tap Release the Alignment Effect.
Tap Confirm to finish the alignment and return to the project alignment interface.

Automatic Marker Alignment¶

Note

When using automatic marker alignment, ensure there are 3 or more common markers between the projects to be aligned.
By default, automatic marker alignment is used. To use other methods, tap the on the interface to expand the alignment method selection list and disable Automatic Alignment.

Tap on the fixed and floating windows respectively to open the project list and select the projects to be aligned.
Note
- You can perform zooming, rotating, and other operations on the fixed and floating windows of the interface to view the selected data models.
- If you need to reselect projects, tap to expand the project list for selection and replacement, or tap to clear the currently selected projects on the interface and then reselect.
Tap Start Alignment to begin project alignment, stitching the project from the floating window to the project in the fixed window.
Tap Confirm to finish this alignment and return to the alignment interface.

Note

If there are 3 or more projects in the project group, after alignment is completed, you can repeat the above steps until all projects are aligned.
After completing the alignment, if you need to undo the alignment effect, select the aligned object in the project group and tap Release the Alignment Effect.

Manual Marker Alignment¶

If the alignment results from automatic marker alignment are unsatisfactory, you can try using the manual marker alignment method.

Tap the on the interface to expand the alignment method selection list and disable Automatic Alignment, then switch to Manual Marker Alignment.
Tap on the fixed and floating windows respectively to open the project list and select the projects to be aligned.

Note

You can perform zooming, rotating, and other operations on the fixed and floating windows of the interface to view the selected data models.
Select 3 common markers on the projects in both the fixed and floating windows.
Tap Start Alignment to begin project alignment, stitching the project from the floating window to the project in the fixed window.
Tap Confirm to finish this alignment and return to the alignment interface.

Note

If there are 3 or more projects in the project group, after alignment is completed, you can repeat the above steps until all projects are aligned.
After completing the alignment, if you need to undo the alignment effect, select the aligned object in the project group and tap Release the Alignment Effect.
