PIX4Dcatch: 3D scanner
3D models from images & LiDAR
Free · In-App Purchases
DIGITIZE REALITY
Transform your mobile device into a powerful 3D scanner. Simply point and capture images and LiDAR data to create accurate 3D models ready for professional use.
Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocation.
Visualize the captured model in the app, upload and export, and view it in AR.
____________________
WORKFLOW
1 – Scan & Capture
Walk around your site. The app automatically gathers data and provides live feedback using iOS LiDAR, ensuring you capture every detail. For enhanced accuracy, use an RTK device compatible with PIX4Dcatch, PIX4D Autotags with a fully automated workflow, or combine both.
2 – Process, Analyze & Share
Process your data by uploading to PIX4Dcloud for online analysis and sharing, or export to PIX4Dmatic for desktop processing. Both platforms offer a 15-day free trial. Projects can also be exported to third-party photogrammetry software.
Measure spaces, document results, and enjoy all the benefits of a detailed 2D/3D model of your surroundings.
3 – View in AR
Experience an immersive augmented-reality view. Display 3D models and GCPs directly in your phone camera in AR.
