Inputs

O_Solver has the following inputs:

Camera	A pre-tracked Nuke stereo camera that describes the camera setup used to shoot the Source image. This can be a camera you have tracked with the CameraTracker node or imported to Nuke from a third-party camera tracking application. This input is optional. Tip: In Nuke, a stereo camera can be either: a single Camera node in which some or all of the controls are split, or two Camera nodes (one for each view) followed by a JoinViews node (Views > JoinViews). The JoinViews node combines the two cameras into a single output.
Ignore	A mask that specifies areas to ignore during the feature detection and analysis. This can be useful if an area in the Source image is producing incorrectly matched features. This input is optional.
Source	A stereo pair of images. These can either be the images you want to work on, or another pair of images shot with the same camera setup.
