‌3D Solves from a Linearized Shot

You can use SynthEyes to convert a 360VR shot to a conventional linear perspective camera, then track and solve that camera. This can be easier than doing a lot of roto work on some shots, if there is a nicely trackable "clear" area of the shot to use. This workflow also provides a segue to the 3D insertion workflow for downstream applications that don't have a 360VR camera themself.

 Open the shot, marking it with a 360 VR mode of "Present."

 Use the 3D Tracking Setup script to create a synthetic view from a (virtual) conventional linear camera with a large known field of view. (This view is generated and stays internal to SynthEyes by the image preprocessor, using the "Remove" setting for 360 VR mode.)

 Do automatic and/or supervised tracking of the synthetic linear shot,=.

 Solve the linearized shot, producing a 3D camera path and orientation and 3D locations for the tracked features.

 Set up a coordinate system using the 3D locations, orienting the overall scene: "Which way is up?!"

 Convert back to a 360VR shot

 Add additional trackers as desired, to locate additional elements in the overall scene.

SynthEyes will have determined the 3D location of a variety of features in the scene, but only in the direction that the linearized camera was looking. We'd often like to have more trackers, in all directions. There are two workflows for doing that.
