about
nx_essential3d_gate.nx -- benchmark the essential-matrix 8-point estimation (cadtwin P1 pose front). Two
cameras view a non-coplanar 3D cloud; fit E from 12 correspondences via the SVD-free power-iteration null
space; the HELD-OUT epipolar residual (6 points NOT used to fit) proves E is the true two-view geometry,
not overfit. Neg-control (wrong correspondences) -> large residual. This recovers relative pose geometry
from images with UNKNOWN poses = the front of two-view SfM. expect_exit: 0 license_tier: ORIGINAL
