COLMAP vs PhotoCatch

COLMAP is a free pipeline for reconstructing scenes in 3D from ordered or unordered image collections. Its Structure-from-Motion stage estimates camera poses and sparse 3D structure; its Multi-View Stereo stage uses PatchMatch stereo and stereo fusion to produce dense point clouds and meshes. Users can work through a graphical interface or command line. The GUI’s automatic reconstruction tool accepts an image folder and creates sparse and dense results in a workspace folder. For development, PyCOLMAP offers Python bindings for most functionality, and COLMAP can be built as a library for C++ code. Feature extraction options include SIFT, ALIKED, and LoMa; ALIKED and LoMa require ONNX support at build time. It supports a range of camera models and multi-camera rigs. Users can install pre-built binaries or build from source; macOS users also have a Homebrew formula, and a pre-built Docker image includes CUDA support. The library uses the new BSD license, while third-party dependencies have separate licenses. The project describes COLMAP as research software that may occasionally exit ungracefully when constraints are not met.

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.
