In order to take the most detailed and nuanced scans possible, Matterport encourages users to take dozens, if not hundreds (depending on the size) of separate scans to create your Showcase. There is, however, such a thing as taking too many scans, which can lead to issues in both Capture and Showcase.
I. Understanding scans individually
A single 3D scan typically covers about 50 square feet (or 4.5 square meters) - it's important to note that this varies greatly depending on the layout of the site.
II. What determines your scan limit
We previously recommended that users try not to exceed 200 scans-per-model - while this may still be a general benchmark to keep in mind, the ability to scan outdoors, coupled with the introduction of the BLK360, makes simplifying the supported model size to a tangible number of scans impossible.
The limiting factor placed on your scans is entirely dependent on the amount of detail in your Space and the total surface area that's being scanned. This means that, for example, an empty warehouse could have up to 200 scans, but a warehouse filled with racks of small parts may max out at 100 scans - this is because small parts require more detail and will take much longer to process. In addition, the warehouse filled with racks will be harder to navigate, because of the added surface area.
III. How to tell you've exceeded your scan limit
There are several telling signs that you're bumping up against your scan limit - if one (or more) of the things below begin happening, you are either pushing against your scan limit, or have exceeded it entirely.
- Capture device running out of memory when scanning
- Long processing times
- Processing errors
- Failure to process outright
- Excessively long loading times
- Hardware slowdown when viewing
Models that have over 100 scans associated with them (both 3D Scans and 360° Views) are considered to be large models, which will affect your billing parameters - learn more here.
IV. Tips for deleting scans
- Delete scans that are too close together
- When you're looking at your scan points in Matterport capture, delete scanning points that are right next to one to one another - remember, each scan should cover about 50 square feet, so additional scans that fit within that parameter are usually not needed.
- Plan your path before scanning
- This is important, particularly if you're scanning a very large area - print a blueprint of the space and mark all the places where you plan on placing the camera - add additional scans at points of interest where visitors will want to see aspects of the Space in greater detail.
- Alternatively, simply walk through the Space beforehand and plan your camera placement that way.
- Delete unnecessary 360° Views
- 360° Views are a great tool for scanning outdoors - as they are a fixed, entirely spherical view, you really only need one 360° View placement when you're outside. Chances are you've taken a few for comparisons sake - make sure to delete the ones you don't need included in your Space.
- Consistently check on how much Space the Capture app is using
- To do this, open the Matterport Capture app and tap on "Storage and Firmware" - this page will show you how much data you've consumed while scanning.
V. Scanning large, empty Spaces
If you find yourself at a property that is particularly massive (tens of thousands of square feet), like an empty warehouse or stadium, you can complete your scan utilizing these special techniques - this typically only applies to those utilizing Matterport in commercial real estate or architecture and engineering.
