mirror_reflection_matrix — DRIVE decide op

• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.mirror_reflection_matrix(mirror_plane) -> 'np.ndarray' (to call the implementation directly, import drivedecide; drivedecide.mirror_reflection_matrix(mirror_plane) -> 'np.ndarray'; from the registry, opsdrive.get("mirror_reflection_matrix"))

Usage

4×4 homogeneous matrix of the reflection in the plane mirror_plane = (n_x, n_y, n_z, d) (point X lies on the mirror ⇔ n·X = d; n is normalized).

> The detailed description below is the original text — the summary and the headings are translated.

S = [[I − 2nnᵀ, 2dn], [0, 1]]

S·S = I(対合)、回転部の行列式 = −1(向きを反転)。
