OpenMVG vs PhotoCatch

OpenMVG is an open-source C++ library for multiple-view geometry, 3D computer vision, and structure from motion. It provides libraries, binaries, and pipelines for reconstructing 3D scenes from images. Library areas include image manipulation, feature description and matching, feature tracking, camera models, multiple-view geometry, robust estimation, and structure-from-motion algorithms. Its binaries can initialize scenes, detect and match features, perform reconstruction, and export scenes to other multiple-view-stereo frameworks. Those frameworks can compute dense point clouds or textured meshes from exported scenes. OpenMVG is released under the Mozilla Public License 2.0 and is listed as free. The project says it aims to support reproducible research through readable implementations of classic and state-of-the-art algorithms. It is designed for reading, learning, modification, and use, with test-driven development and samples. Tutorials cover data structures, library use, and processing an image dataset. Platforms listed are Windows, macOS, Linux, iOS, Android, and self-hosted, with desktop deployment, API access, point-cloud export, and ground control point support.

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.
