PhotoCatch vs WebODM

PhotoCatch creates 3D models from photos and video, with capture and editing options on macOS and iOS. The desktop app can build models from separate photos, video, or both, then provides texture editing, AR optimization, transform, and crop tools. It exports USDZ and OBJ files; the App Store page says USDZ exports are ready for AR Quick Look and OBJ files work with almost any 3D software. PhotoCatch Cloud brings photogrammetry and 3D editing to mobile for capture, editing, and sharing on site. Its Depth Capture feature is intended to keep a model at the same scale as the real-world object. The maker presents PhotoCatch for personal, business, and enterprise uses such as AR, VR, construction, real estate, VFX, and online shopping. Desktop requirements are macOS 12 Monterey or later and Apple Silicon; some Intel Macs may work with 16 GB RAM and a compatible AMD GPU with 4 GB VRAM. The free plan is free. Monthly options are Essentials at 4.99 USD, Pro at 9.99 USD, Small Business at 19.99 USD, and Corporate at $49.99 a month.

WebODM turns aerial images into georeferenced maps, point clouds, digital elevation models, textured 3D models, and Gaussian splats. It accepts photos or videos from any drone, including JPG, TIFF, video files, and multispectral imagery, and can run on a user's computer while offline. Exports include GeoTIFF, PNG, LAS/LAZ, OBJ, and OGC 3D Tiles. Mapping tools cover measurements, plant-health indexes, ground-control points, elevation contours, rolling-shutter correction, and sharing links. WebODM uses ODX, a free, open-source photogrammetry engine that developers can run from the command line or integrate into software. It can also connect to processing nodes that speak the NodeODX API. The API uses token authentication through the /api/token-auth/ endpoint, with tokens expiring after six hours by default. Model-level and row-level permissions govern whether users can view, add, edit, or delete objects. WebODM is free to install and use locally; optional cloud plans are listed at $24 a month billed yearly for Starter, $35 a month billed yearly for Pro, and $99 a month billed yearly for Business. Minimum requirements are 8 GB RAM and 20 GB disk space; larger datasets have higher recommended requirements.
