Get started with your scanning kit 

This article provides step-by-step instructions for using PIX4Dcatch with a supported RTK device, covering the entire workflow from initial setup and NTRIP configuration to capturing and processing your 3D scanning projects.

PIX4Dcatch is a mobile application designed for terrestrial 3D scanning. It captures high quality spatial data using your mobile device and a supported RTK device, which can then be processed into accurate 3D models using photogrammetry.

Requirements 

• A mobile device compatible with PIX4Dcatch. See the list of compatible devices here.
• The Pix4Dcatch application.
• A stable internet connection.
• The SP connector compatible with your mobile device.
• An active NTRIP service subscription or a GNSS base with NTRIP caster.
• The supported RTK hardware.

The connection card displays:

• RTK status (Fix,Float, DGNSS only, Autonomous GNSS). RTK Fixed provides the highest accuracy.
• The number above the signal icon shows the number of satellites in use.
• H and V indicate horizontal and vertical accuracy.
• A clear sky view and a reliable internet connection are recommended.
  
  

5. Capture a project

To capture a project using RTK supported devices,  select RTK via Bluetooth. For more information on how to capture a project, click here.

Recommended Capture Practices:

• Maintain a slow and steady pace.
• Tilt the device to ensure all surface details are captured.
• Avoid capturing in low light environments.
• Avoid retracing identical paths.

6. Process the images

Once the project is saved, the images can be processed using PIX4Dcloud or exported for local processing with PIX4Dmatic Standard or PIX4Dmatic Pro.

PIX4DCloud

Use the upload button to upload your project for fast, shareable 3D reconstruction. For more information on how to process, click here.

 PIX4Dmatic

PIX4Dmatic Standard or PIX4Dmatic Pro allows local processing of PIX4Dcatch projects.

How to process in PIX4Dmatic

1. Tap the Export  icon and select Export All Data - PIX4Dmatic (OPF). For more information, click Using OPF from PIX4Dcatch to PIX4Dmatic.

2. Double-click on the project.opf file.
3. PIX4Dmatic will launch automatically, displaying the project name and file path.
4. Click Start.
