Camera PnPoint - perspective matching and lens calibration

Camera PnPoint is an add-on for Blender that brings a powerful PnP solver to the camera tracking workbench. Perspective-n-Point is the problem of estimating the pose of a calibrated camera given a set of known 3D points and their 2D projections in the image.

The add-on also includes a camera Calibration solver that allows adjusting the most relevant camera intrinsics, like focal length and radial distortion coefficients, using projection data from the 3D and 2D markers.

This add-on uses OpenCV library, which needs to be installed in the Blender path. The add-on’s preferences panel includes a functionality to automatically install the package if it is not found. You may need to start Blender with elevated privileges for this to work.
