[360° Scan] Matterport Tutorial: Multi-Story Buildings, 5 Tips for Alignment!
Even department stores can be scanned! Advanced 360° scanning, multi-story building scanning methods, staircase alignment techniques, scanning sequence tutorial, quick space conversion, immersive experience without VR, learn scanning tips now:
Following the previous Matterport Pro2 beginner's tutorial (click here), in addition to basic usage, we will successively introduce more detailed operating steps. When using Matterport Pro2 for 360° scanning of multi-story buildings, learn these five tips and even department stores can be easily scanned!
I. Multi-Story Staircases, Scanning Sequence
1. Scan floors from bottom to top
2. Scanner upward movement distance < 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.
．If scanning a spiral staircase, it is recommended to scan each 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 a name to start scanning
(Important note: The staircase from the 1st floor up to the 2nd floor, the 360° scanning area belongs to the 1st floor, and the concept extends 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 to move the scan point to
III. Edit Floors
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 hold the three bars on the right
IV. Floor Alignment
Matterport scanning alignment technology aligns each scan point with the previous one, overlapping 2D and 3D data in Matterport Capture software, aligning 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 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 analysis fails to align and stitch, an alignment error prompt will appear.
Halve the distance of the completed scan point from the previous step, then attempt to continue scanning; if alignment still fails, delete the completed scan point from the previous step and scan that point again, repeating this deletion and re-scanning process until alignment is restored.
3. Misalignments
Misalignment is different from alignment error. Misalignment occurs when the Matterport Capture detects the space as aligned, but the actual scan result is stitched in the wrong location. (For example: In the software system, scan point 7 is displayed between scan points 5 and 6; but in reality, the 7th scan point is at the location of the orange circle, this is an instance of scan point 7 being misaligned.)
Spatial misalignments accumulate. 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. Recovering from Misalignment
1. Delete unaligned scan points
Find the misaligned scan point, delete it, then go back to half the distance between the previous two scan points, and try scanning again. If it is successfully fixed, you can continue scanning.
2. Delete the first two scan points
If point 1 cannot be successfully fixed, 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 lower the tripod, until re-alignment. (Important note: Remember to hide excess scan points in the Workshop before finishing.)
