fSpy is an open source, cross-platform desktop app for still image camera matching, computing camera parameters from a reference image. It includes an official Blender importer add-on that applies the computed parameters to a Blender camera.

Use cases

• match a 3D camera to a still photo for compositing
• calibrate camera parameters from vanishing points in an image
• import camera parameters into Blender for photorealistic scene setup
• set up camera position, orientation, and field of view from a reference image
• use computed camera parameters in other 3D applications

When to choose

• you need to composite 3D objects into a photograph in Blender
• you want a free, open-source alternative to manual camera calibration
• you need a standalone GUI tool rather than a script inside a 3D app

When to avoid

• you need video or moving-image camera tracking rather than still images
• you need automated calibration without manually picking reference lines
• you require an actively developed tool with recent updates
