depth op• Data kinds: image2d → depth
• Call: import fullseye as fs; fs.ledger.lf_disparity_to_depth(slope, focal_px=1000.0, baseline=1.0, *, far_depth=None, min_slope=1e-06) (implementation को सीधे call करना हो तो import lightfield; lightfield.lf_disparity_to_depth(slope, focal_px=1000.0, baseline=1.0, *, far_depth=None, min_slope=1e-06), registry से लेना हो तो opslightfield.get("lf_disparity_to_depth"))
slope (हर angular step पर px) -> metric depth, camera-array model।

For a rectified array of viewpoints spaced *baseline* apart with focal length *focal_px* expressed in pixels of the sub-aperture image, a point at distance Z shifts by |s| = focal_px * baseline / Z pixels per step. Inverting: Z = focal_px * baseline / |s|, returned in whatever length unit *baseline* was given in (mm in, mm out).
Only |s| enters, deliberately. The *sign* of the slope says which side of the focal plane a point is on, and which sign means "nearer" depends on how the angular axis was oriented when the field was decoded — a convention this module cannot know and refuses to guess. If your decode puts near objects at negative slope, negate before calling.
*far_depth* is the fail-closed switch for the s -> 0 pole (a point at infinity has zero parallax). None (default) makes any |s| < min_slope a ValueError naming how many pixels were affected — mask them, or pass an explicit saturation distance as *far_depth* and get that value there. There is no silent inf and no silent clamp.
Accepts a scalar or any array; returns the same shape (a scalar in gives a 0-d array out, so downstream code has one type to handle).
Raises ValueError: non-finite *slope* / *focal_px* / *baseline*, a non-positive *focal_px* / *baseline* / *min_slope*, a negative *far_depth*, and |slope| < min_slope anywhere when *far_depth* is None.
