Alignment

You can use the alignment function to combine scan data from multiple projects into a complete 3D model to enhance the integrity of the scan data.

Click on the top panel to enter the alignment interface.

Caution

  • The project alignment can only be accessed by project files with generated point clouds.

  • At least 2 or more project files need to be selected.

  • If a project hasn't been generated point cloud enters the alignment process, a prompt will appear. Please follow the instructions to generate the point cloud first.

  • The fixed window means that the object's actual coordinates will not change during alignment, while the floating window means the object's coordinates will change.

  • It is recommended to use feature automatic alignment or marker automatic alignment. If you need to use manual alignment, use Shift + LMB click to select three common points / markers on the object's surface to perform alignment.

  • Projects after alignment will be merged into a Group, and you can choose the Group for meshing.

Alignment Description
Notes

Automatic Feature Alignment
  1. Select the Auto Feature Alignment mode.
  2. Select the projects in the fixed window and floated window for alignment.
  3. Click Apply to align based on common features in the project files.
 Regular shaped objects (circular objects and square objects included) or small sized objects are not suitable for this mode.

Manual Feature Alignment
  1. Select the Manual Feature Alignment mode.
  2. Select the projects in the fixed window and floated window for alignment.
  3. Manually choose at least 3 common points in the fixed window and floated window.
  4. Click Apply to align.
  • The chosen points should not in a line.
  • Manual alignment is a supplement to feature alignment, which can solve the problem of feature alignment failures such as some areas with few common areas or extremely similar areas. The data is aligned by the best fit of all points of the data in the floated viewport and the fixed viewport.

    Automatic Markers Alignment
    1. Select the By Markers mode.
    2. Select the projects in the fixed window and floated window for alignment.
    3. Automatically identify common markers on both project files.
    4. Click Apply to align.
    		 The two projects have no less than 3 common markers each other.

    Manual Markers Alignment
    1. Select the Manual Markers Alignment mode.
    2. Select the projects in the fixed window and floated window for alignment.
    3. Manually select at least 3 common markers on each of the project files.
    4. Click Apply to align.
  • The selection of markers should be as separate and random as possible.
  • The selected markers will be cleared after aligning.
