Frequently Asked Questions
What devices does Metascan run on?
Metascan supports any iPhone or iPad from 2015 or later that runs iOS 14. LiDAR Mode requires a device with LiDAR Scanner, such as an iPhone 12 Pro or iPad Pro 2020.
Does my data stay on my device?
LiDAR Mode processes completely on-device, while Photo Mode uploads your photos to our photogrammetry server for processing. The photos are deleted as soon as your model is processed.
Sharing a scan using Upload Scan uploads it to our web server. You can delete it at any time using Delete from Cloud in the app.
What does the Metascan Pro subscription give me?
Available as either a monthly or annual in-app subscription, Metascan Pro unlocks the following features:Export to all supported file formats.Highest resolution LiDAR scans.Process 150 photo scans every 30 days.
Metascan Pro has a one week free trial period.
What file formats does Metascan Pro export to?
Metascan currently supports:
USDZ is an open standard, supported natively on iOS and macOS.FBX is a closed format, created by Autodesk and widely supported by 3D software applications and game engines.OBJ is a simple text-based format which is supported by almost all 3D software. Metascan stores the OBJ file and its JPEG textures in a ZIP file when exported.glTF is an open standard format for sharing 3D data on the web. Metascan uses the .glb format to embed all data in a single file.PLY is a simple format used for sharing point cloud data. Metascan stores the 3D position and color data in binary.LAZ is a widely used format for sharing point cloud data that is georeferenced so can be imported into a GIS system such as QGIS for analysis.
When exporting multiple scans, files are stored in a single ZIP file. Contact us if you'd like to see additional formats supported.
What units are exported models measured in?
All coordinates are expressed in units of meters.
How are model textures exported?
Texture maps are stored in one or more square RGB images at maximum 4096x4096 pixel resolution and compressed with JPEG to 92% quality level using 4:2:0 Chroma subsampling.
How do I take better LiDAR scans?
Taking good scans requires practice. Here are some tips:Scan bright, well-lit areas and try to avoid capturing small objects.Make sure your camera lenses are clean. Wipe them with a cloth before starting.Check that the tracked feature points (colored dots) appear stable before you start scanning.Aim to keep between 0.5 to 3.0 meters between you and the surface you're scanning.Avoid moving too quickly – it causes camera motion blur.Avoid transparent, shiny or reflective surfaces such as windows, metal or mirrors.Avoid any moving objects, people or animals.
How do I take better photo scans?
Photo Mode uses photogrammetry which relies on matching image features between photos to estimate distance. Here are some tips to improve your scans:Non-transparent, unreflective objects with varied surface textures scan best.Capture all sides of your object in a series of orbits.Adjacent shots should have 70% overlap or more for alignment.Minimize motion blur by holding your device steady while taking a photo.Make sure you have even, good lighting and a stable environment for scanning.If scanning outdoors, cloudy days work best.
