2.3 Using Multiple Views to Solve Nodal Pans

2.3 Using Multiple Views to Solve Nodal Pans

There is one special kind of camera motion, that requires additional views to extract any kind of 3D: Nodal pans. This tutorial explains what nodal pans are and how they are different from other camera movements. After that we will use the same technique shown in the live session to add additional camera views of the same scene in order to obtain a real 3D result.

In the Extended Matchmoving in PFTrack class we have used PFTrack’s photogrammetry tools to help us solve multiple camera motions into a single scene. These tools can also be used to create textured triangular meshes. This tutorial will walk you through the necessary steps to create a mesh from the scene created in the live training.

2.1 Solving Multiple Cameras Into a Single Scene

2.1 Solving Multiple Cameras Into a Single Scene

When tracking multiple shots from the same location, it is often important that every shot shares the same coordinate system. This way we can ensure that key locations are identical independent of which camera solve is worked on. A straightforward way to ensure a shared coordinate system for multiple cameras is to track and solve them into the same scene in PFTrack.
