About:
fSpy is an open-source tool for still image camera matching. It helps you find the focal length and position of a camera used to take a photograph by analyzing perspective cues in the image. This data is invaluable for 3D artists needing to integrate CGI elements realistically into a background plate.
Key Features:
  • Automatic and manual camera matching
  • Supports multiple vanishing points for complex scenes
  • Export camera data to popular 3D applications
  • Cross-platform availability
Use Cases:
  • VFX and 3D artist workflow for matching live-action footage
  • Architectural visualization and rendering
Alternatives:
  • Blender (fSpy Importer) – fSpy is a dedicated utility; Blender uses its add-on to import the .fspy project file to set up the camera.
