About Scanner - Structure SDK

This app is made for the Structure Sensor accessory. If you do not have a Structure Sensor accessory, please visit to learn more.

Capture objects in 3D with your Structure Sensor.

This simple and easy to use application allows you to capture 3D models of objects and people by simply walking around them with your iPad and the Structure Sensor accessory.

Captured objects can be sent via email (uses OBJ format).

Download the new "Structure Sensor Calibrator" app for best color results.

Scanner v2.0

- Battery depleted events are no longer sent when the device hits 10% if the user started scanning above 10% battery charge remaining.

Scanner v1.12

- Structure Sensor (Mark II) Firmware 1.0 support

- Fixed misc. crashing related to background and foreground app transitions (using Structure Sensor (Mark II) with Firmware 1.0)

- Fixed misc. crashing and failures related to starting and stopping streaming (using Structure Sensor (Mark II) with Firmware 1.0)

- Low battery notifications will now be sent during scanning (using Structure Sensor (Mark II) with Firmware 1.0)
Jan 9, 2020
Scanner v1.11.2:

- Fixed a bug where Structure Sensor (Mark II) would either fail to stream after restarting or switching streams several times, or the frame rate would slow down every time streaming would restart.
Dec 18, 2019
Scanner v1.11:

- Structure Sensor (Mark II) connection and stability have been greatly improved
- An in-app notification has been added to inform you when a firmware update is available for your Mark II sensor
- Resolved a crash that would happen when the camera permissions dialog box appears for the first time
- Fixed a bug where apps would crash when backgrounded by the OS
- Fixed a bug where Structure Sensor (Mark II) would not reconnect after an app was backgrounded
- Fixed a bug where unplugging and replugging Structure Sensor (Mark II) would crash the application
Oct 28, 2019
Scanner 1.10.2:

- Improved Structure Sensor (Mark II) battery state checking - apps no longer report that Mark II requires charging when the battery level is at 60% or below.
- Improved handling of Structure Sensor (Mark II) disconnection events - apps no longer freeze when Mark II is disconnected due to being unplugged or battery depletion.

Release Version 1.10

- A new settings menu has been introduced. It can be found by pressing the settings gear icon in the top left corner. Examples of this are changing the exposure and gain settings on the IR camera, to better adjust to different lighting conditions in your scans.
- Some UI elements have been shifted or resized to better fit in iPhone layouts.- Some UI buttons have been given updated graphics. We hope you like our new icons!
- We have also introduced the concept of sensor depth stream presets. These presets are a work-in-progress, but should provide better depth coverage when doing body-scanning or scanning outdoors. Select these options (i.e. Default, Body-Scanning, Outdoors) from the settings gear in the top left corner of the app.
- A new calibration overlay has been added to the Scanner sample that provides better instructions for calibrating when approximate calibrations are not available, e.g. when using custom iPhone cases.
- A bug has been fixed where backgrounding the app or receiving a notification could crash the app.

Version 1.9.1

- Now with approximate default calibration for 2018 iPad Pro devices, allowing quick usage prior to running Calibrator.
- Fixed a bug on iPhone devices where calibration overlay would not disappear even after calibrating.
- Fixed a bug where OCC files would be written to the app documents directory after every scan.
Feb 6, 2019
Version 1.9:
• Now optimized for newer (post-2017) devices, especially improved texture to mesh alignment, and when scanning without having performed calibration.
• Additionally, the Scanner Sample App has been optimized to work better on iPhone-family devices, specifically the UI layout has been fixed to show messages that were sometimes offscreen.
• Supports higher color resolutions for mesh texturing on newer (post-2017) devices when using the “High Resolution Color” setting.
• Fixed a race condition in the Scanner Sample App where the calibration overlay would pop up even if you have already run through Calibrator.
• Fixed a bug where some UI elements would no longer be interactive after the Structure Sensor is disconnected and reconnected.
• Fixed a bug where toggling high-resolution color would crash the app on certain (post-2017) devices.
• Fixed a bug where keyframes would sometimes never be added, causing a message “Please hold the device still while we collect a keyframe” to indefinitely overlay the scan.
• Developed on top of Structure SDK 0.9
Jan 3, 2017
• This update fixes an issue where first-time streaming could fail under certain circumstances.
• Built with Structure SDK 0.6.2.
Nov 3, 2016
- Fixed a problem where geometry touching the edges of the scanning volume could be jagged.
