[Global View Scan] Matterport Tutorial: 5 Secrets to Multi-Layer Buildings and Alignment!
Department stores can be scanned too! Advanced panoramic scanning techniques, multi-story building scanning methods, staircase alignment techniques, scanning sequence tutorials, rapid space transitions, immersive experience without VR—learn scanning skills now!
Following the previous Matterport Pro2 beginner's guide ( click to view ), in addition to the basic usage, we will also be releasing more detailed operation steps one after another. When using Matterport Pro2 to scan multi-story buildings, learn five tips so that you can easily scan department stores!
one, Multi-level staircase, scanning order
1. Scan the floors from bottom to top
2. The scanner moves upwards a distance of less than 30 centimeters (approximately 5 walking steps).
Each scan must be performed within the line of sight of the previous scan.
It is recommended to scan every other staircase.
If scanning a spiral staircase, it is recommended to scan each staircase to ensure alignment.
3. After the staircase scan is complete, click the "Select Floor" icon.
(Important Note: To ensure accurate alignment and connection between floors, when adding a new floor, you must confirm that the "last scan point" of the "previous floor" is at the "top floor" of the staircase.)
4. Add a new floor
5. Enter a name to start scanning.
(Important note: The perimeter scanning area of the staircase from the 1st floor to the 2nd floor is on the 1st floor, and the concept continues in this manner.)
two, Return to floor scan
1. In the preview window, select the scan point (blue circle) to which you want to move.
2. Select "Move to Floor"
3. Select the floor where you want to move the scan point.
three, Edit Floor
1. In the preview window, click the "Select Floor" icon.
2. In the opened window, click the Edit button.
3. Delete post: Click the red circle next to the name.
4. Change floor order: Select and press the three columns on the right.
Four, Floor alignment
Matterport scan alignment technology aligns each scan point with the previous scan point, overlaying 2D and 3D data in Matterport Capture software and aligning based on areas with high similarity.
1. 6 Tips for Successful Alignment
After completing the scan, immediately mark the windows and mirrors.
Without markings, the reflection in the mirror would be perceived as another room by Matterport , thus creating an alignment discrepancy.
Keep the door either open or closed at all times.
Reduce the distance between scans.
Avoid direct sunlight and outdoor scanning.
Each scan must be performed within the line of sight of the previous scan.
Begin 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 the stitching, an alignment error message will pop up.
Reduce the distance between the scan points completed in the previous step by half, and then try to continue scanning. If alignment is still not successful, delete the scan points completed in the previous step and scan the points again. Repeat this deletion and rescanning process until alignment is restored.
3. Misalignments
Misalignment is defined differently from alignment error. When Matterport Capture detects that the space is aligned, but the actual scan result shows the points stitched together in the wrong location. ( For example, in a software system, scan point 7 is displayed between scan points 5 and 6; however, the 7th scan point is actually located at the position of the orange circle. This is a case of scan point 7 being misaligned.)
Spatial misalignments can overlap, and too many misalignments may cause problems with the subsequent path display. It is recommended to zoom in and check the misaligned scan points after each scan.
V. Misalignment Restoration
1. Delete misaligned scan points
Find the misaligned scan point, delete it, return to half the distance between the first two scan points, and try scanning again. If the problem is successfully fixed, you can continue scanning.
2. Delete the first two scan points
If point 1 cannot be repaired successfully, please delete the first two scan points and scan again on the last scan point; as shown in the figure, if the misalignment is caused by scan point 10, delete scan point 10 and scan point 9, and rescan on scan point 8.

3. Scanning distance halved
Scan at half the normal scanning distance, or by lowering the tripod, until realigned. (Important: Remember to hide any extra scan points in the Workshop before finishing.)
