fSpy is an open-source, cross-platform application designed to accurately match the perspective of a 3D camera to a 2D image. fSpy facilitates the integration of 3D elements with real-world scenes. It estimates camera parameters, such as focal length, orientation, and position in 3D space, based on user-defined control points in 2D images. These parameters can then be used in various applications, particularly 3D modeling tools.
Key features
- Camera matching: fSpy computes the parameters of a 3D camera to align with the perspective seen in a 2D image.
- Cross-platform availability: The application is available for Mac, Windows, and Linux.
- Blender integration: An official fSpy importer add-on for Blender allows users to set Blender camera parameters and optionally set the camera background image.
- Importing to other applications: Users can copy and paste camera parameters from fSpy into other 3D applications that do not have a dedicated importer.
Integration
fSpy integrates with Blender through an official importer add-on. For other applications, it provides flexibility by allowing users to manually transfer camera parameters, ensuring compatibility even without dedicated support.
Typical workflow
- Load Image: Import a still image into fSpy.
- Define Control Points: Identify and mark control points in the image that align with real-world features.
- Compute Parameters: fSpy calculates the camera parameters, including focal length, orientation, and position in 3D space.
- Export Parameters: Export the calculated camera parameters. For Blender users, this involves using the fSpy importer add-on. For other applications, manually copy and paste the parameters.
- Adjust Camera Settings: In the target application, set the camera viewport to match the dimensions of the input image, use the input image as the camera background, adjust the camera’s field of view, position, orientation, and principal point as necessary.
