Python loadXform Examples

Example #1

    X = loadPoints(Path("tests/fixtures/ref.txt"))
    Y = loadPoints(Path("tests/fixtures/deg.txt"))
    expected = loadXform(Path("tests/fixtures/affine.pickle"))

    P, xform = last(islice(driftAffine(X, Y, w=0.5), 100))

    np.testing.assert_almost_equal(xform.B, expected.B)
    np.testing.assert_almost_equal(xform.t, expected.t)
