Firstly, I undistorted the shot with lensDirstortion node. I used the lens grid to detect the distortion and solved it. It’s very important to undistort the scene because there is always lens distortion with modern cameras, and there is no lens distortion for the cameras in Maya.

I tracked the scene and solved it, exported the scene+. After I got the camera and scene, I created sphere and planes as reference in 3D space to see how my tracking works.

Once I make sure the tracking is good, I exported the camera and pointclouds into Maya as FBX files.
