Scanning Guide for Area Targets Using Matterport™

vuforia-scanning-practices-using-matterport-3d-scans

Area Targets are created from a 3D scanned digital model of a physical space. Such a model can be obtained by using a 3D depth scanning camera. This guide lists the supported devices and the guides on using the technology to capture a rich and detailed model of your environment. Get started creating engaging AR applications for large environments, rooms, and spaces! The surrounding environment is your target playground!

Supported Devices

  • Matterport™ Pro2 Camera

Currently, only the Matterport™ Pro2 Camera is supported for this feature. Follow this guide to set up your Matterport™ Account and start scanning your chosen space to get an accurate digital replica of your environment.

NOTE: A Matterport™ Token ID and Token Secret are required for the Area Target Generator to retrieve scans that are hosted on your Matterport™ account. You need to have admin privileges to the account to obtain the token pair by navigating to the Account settings->Manage->API Token Management section. See Area Target Generator User Guide for detailed instructions on how to use the Token ID.

Equipment

In addition to the Matterport™ Pro2 camera, available via https://matterport.com/pro2-3d-camera/ some additional equipment is required for obtaining a successful scan. These include:

  • Professional grade tripod

The Pro2 3D Camera weighs 7,5 lbs. (3,4 kg) and rotates 360 degrees while scanning. Therefore, it is necessary to use a high-quality tripod that will not move or shake during the scanning process. It should be height adjustable. We recommend using some heavy-duty stand available from professional vendors.

  • Quick-release clamp

We also recommend purchasing an Arca-Swiss compatible quick-release clamp that allows for easy fixation and release of the scanner on the tripod. This speeds-up handling of the Pro2 3D Camera during scanning.

  • iPad tablet or iPhone 6s or newer

The Matterport™ Capture App, required to control the Matterport™ camera is only supported on iOS devices. The app connects to the Matterport™ camera and is necessary for controlling and managing the scans. It is free to download from the Apple App Store.

For further details and specific recommendations see the Matterport™ Tripods, quick release clamps, and cases guide.

NOTE: In some situations, the abovementioned equipment might be acquired through rental or data generated by a full-service provider or an agency.

Preparing the Camera and the Environment

Before heading to the scanning site, it is always good to ensure that the camera and iOS device is fully charged. We also recommend transporting the equipment safely in sturdy cases.

Preparing the Environment

For a full coverage of the best practices for preparing and scanning an environment, please refer to Best Practices for Choosing and Scanning Environments. However, some device-specific recommendations are listed below.

  • Minimize incoming sunlight from windows by closing the curtains or blinds. At the same time ensure enough ambient lighting is provided, by e.g. switching on lamps and lighting, providing a typical lighting scenario.
  • Scanning outdoors with the Matterport camera is currently not advised or supported for creating Area Targets because bright sunlight can negatively impact the 3D data from a scan and lead to alignment issues and poor 3D geometry. Sunlight makes it very difficult to create a compact mesh of the scanned area.
  • Additionally, Matterport’s ‘360-degree views’ (panorama images) are not supported as they do not contribute to the dollhouse or floorplan view.

Scanning the Environment

Mount the camera with the clamp and turn on the iOS device and the camera. Connect the Matterport™ scanner with the Matterport™ Capture App through the camera’s Wi-Fi that should be visible on the iOS device. Use the create new button to create a new model and the blue circle to start scanning. The camera will perform a 360-degree rotation to scan its surroundings (make sure you are not in the field-of-view). A preview will gradually appear in the capture app. Use the capture app’s tools (Mirrors, Trim, and Windows) in-between scans, to mark highly reflective facades and outdoor facing windows as it will help reduce alignment errors. For more detailed information on the scanning process, please consult Matterport’s Scan a Space Guide.

NOTE: The ‘Mirror’ tool should be used to mark reflective surfaces such as mirrors, screens and glossy metals. Make sure the arrow in the marking is facing the correct way.

Uploading the Scan

When the scanned environment is complete, press the upload button in the Matterport™ Capture App menu to upload it to your account for processing. Do not forget to disconnect from the Camera’s WIFI and connect to a different one for the upload process. Due to large file sizes, a stable network is recommended.

NOTE: Once a scan is uploaded to your Matterport™ account, processing can take several hours, depending on the size of the scan. Due to this processing delay in most cases, you will not be able to generate the Area Target directly at scanning-time. Therefore, we advise you to plan an additional on-site-trip for testing the Area Target.

Purchasing the MatterPak™

Using the uploaded 3D scan, the Matterport™ cloud service generates several derived products automatically. A couple of hours after the upload finished you will receive a notification from Matterport™. Visit your Matterport™ account and open the specific space.

matterpak-purchase-screen

Navigate to the “MatterPak™” section of the space associated with the scan. Confirm the purchase using the “Buy” button. This button will change into a “Download” button after the purchase process has been finished. Although it is not a requirement, you can download your completed model directly. Using the token authentication, the Area Target Generator is connected to your Matterport™ account and will retrieve the necessary data for target generation. For additional information, visit the Matterport™ support site on Downloading the MatterPak™ bundle.

NOTE: Mattertags (annotations and snapshots added to the 3D model for presentation) are not included in the Area Targets creation process. Such markup components should be authored in the Unity Editor or coded in your native application.
