PIX4Dcatch vs PIX4Dmapper

PIX4Dcatch is a mobile app for capturing ground scans and turning terrestrial data into 3D models. It records image frames with position and orientation information and gives real-time feedback on scan coverage. Georeferenced models are created with photogrammetry and LiDAR; LiDAR depth capture is used by the iOS version, while Android processing does not use depth data. Processing happens off the phone and requires a valid PIX4Dcloud or PIX4Dmatic license or trial. Captured data can be uploaded to PIX4Dcloud or exported to PIX4Dmapper or PIX4Dmatic, and the product page describes overlays for DXF, IFC, and SHP designs. Phone GNSS location is expected to be accurate to a few meters; a supported RTK device can provide absolute accuracy in the range of a few centimeters, with compatible equipment and an active regional NTRIP subscription. After login, capture can work offline, but cloud uploads need internet access. PIX4Dcloud can process up to 4,000 images per project. The Discovery license is free; PIX4Dcatch Pro is $132.50 a month, billed yearly, excluding taxes.
