PIX4Dcatch is the tool for acquiring optimal ground images for photogrammetry. These ground images can be used to get highly accurate 3D models on PIX4Dcloud or offline within PIX4Dmapper.

No need to be an expert. Walk around your area of interest and the app will record pictures along the way, together with GPS positions. Using augmented reality, get live feedback on the covered area and the completeness of the scan thanks to the overlaid 3D mesh on the current video frame that is available for devices with LiDAR sensors.

Images can be uploaded to PIX4Dcloud for a fast generation of scaled and georeferenced 3D models and point clouds, that you can visualize, measure, share, and export. Or they can be exported locally for processing in PIX4Dmapper.

Workflow

1. Scan: Walk around the area of interest. PIX4Dcatch automatically records geotagged frames and displays on your screen real-time 3D meshing for scene completion feedback.
2. Upload: Stop recording and automatically upload images to PIX4Dcloud to generate accurate and easy to share 3D models.
3. Export: transfer the images from your device to your desktop computer and start the photogrammetry process, add GCPs, and validate the accuracy of your 3D scene.
4. Examine: Measure distances, areas, and volumes, and perform virtual inspections.
5. Share: Selectively and securely share project data and insights with your team, clients, and suppliers.
