【360° Scan】Matterport Tutorial: Multi-Story Buildings, 5 Alignment Tips!
Even department stores can be scanned! Advanced 360° scanning for multi-story buildings, staircase alignment tips, scanning order tutorial, fast space transitions, immersive experience without VR. Watch the scanning tips now:
Following our previous Matterport Pro2 beginner's tutorial (click here to view), in addition to basic usage, we will progressively introduce more detailed operational steps. When using the Matterport Pro2 for 360° scanning multi-story buildings, master these five key techniques, and you'll be able to easily scan even department stores!
I. Multi-Story Staircase Scanning Order
1. Scan floors from bottom to top
2. Scanner moves upward less than 30 cm (approx. 5 steps)
．Each scan position must be within the line of sight of the previous scan.
．It is recommended to scan every other stair.
．When scanning spiral staircases, it is recommended to scan every stair to ensure alignment.
3. After scanning the stairs, click the "Select Floor" icon
(Important note: To ensure accurate alignment and connection between floors, when adding a new floor, it is crucial to confirm that the "last scan point" of the "previous floor" is at the "topmost stair.")
4. Add new floor
5. Enter the name to start scanning
(Important note: For stairs going from the 1st floor to the 2nd floor, the 360° scanning area belongs to the 1st floor, and the concept applies similarly.)
II. Return to floor scanning
1. In the preview window, click on the desired scan point (blue circle) to move to
2. Click "Move to Floor"
3. Select the floor you want to move the scan point to
III. Edit Floor
1. In the preview window, click the "Select Floor" icon
2. In the opened window, click the edit button
3. Delete floor: Click the red circle next to the name
4. Change floor order: Click and press the three bars on the right
IV. Floor Alignment
Matterport scanning alignment technology aligns each scan point with the previous one, overlaying 2D and 3D data in the Matterport Capture software to align based on areas with high similarity.
1. 6 tips for successful alignment
．Immediately mark windows and mirrors after scanning
If not marked, reflections in mirrors will be treated as another room by Matterport, leading to alignment discrepancies.
．Keep doors consistently open or closed
．Reduce the distance between scans
．Avoid direct sunlight and outdoor scanning
．Each scan position must be within the line of sight of the previous scan
．Start scanning the new floor directly next to the last scan point of the previous floor
2. Alignment Errors
When the Matterport Capture system fails to align and stitch, an alignment error indicator will pop up.
Reduce the distance of the previously completed scan point by half, then try scanning again. If it still fails to align, delete the previously completed scan point and rescan that point. Repeat this deletion and rescanning process until alignment is restored.
3. Misalignments
Misalignment is different from alignment error. Misalignment occurs when the Matterport Capture detects that the space is aligned, but the actual scanning result is stitched to the wrong location. (For example: in the software system, scan point 7 appears between scan points 5 and 6; but in reality, the 7th scan point is at the position of the orange circle. This is a misalignment of scan point 7.)
Spatial misalignments accumulate, and too many misalignments can lead to subsequent path display issues. It is recommended to zoom in and check for misaligned scan points after each scan.
V. Misalignment Recovery
1. Delete misaligned scan points
Find the misaligned scan point, delete it, then move back halfway between the previous two scan points and try scanning again. If successful, you can continue scanning.
2. Delete the previous two scan points
If step 1 fails to fix the issue, delete the previous two scan points and rescan at the last scan point. As shown in the figure, if scan point 10 caused the misalignment, delete scan points 10 and 9, and rescan at scan point 8.

3. Halve the scanning distance
Scan at half the normal scanning distance or after lowering the tripod until re-alignment is achieved. (Important note: Remember to hide excess scan points in Workshop before finishing.)
