Digitize Reality: Transform your mobile device into a powerful 3D scanner. Simply point and record to create professional-grade 3D models. Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocated 3D reconstructions. Visualize the captured model in the app, upload and export, and view it in AR. New ArcGIS Workflow: PIX4Dcatch now streams ArcGIS data in realtime in AR to provide in-field operators full contextual information about the entire site including 3D reconstructions and attributes. Our capture feature generates complete and defensible georeferenced 3D reconstructions which can be communicated seamlessly back to ArcGIS. New Guide-To Feature: PIX4Dcatch has a guide-to feature directing users to specified geolocated assets for staking, boosting onsite efficiency and accuracy. Just select the point or reconstruction you would like to find and follow the arrows in AR. WORKFLOW 1 – Scan & Capture Walk around your site.
