triangulate_column — 3D `structured_light` op

• Data kinds: image2d → depth

• Call: import fringe; fringe.triangulate_column(column, k_cam, k_proj, rot, trans) -> 'np.ndarray' (or ops3d.get("triangulate_column"))

Usage

Triangulate the depth Z from the "projector column number" of each camera pixel (the final stage of structured light).
