keypoints_uv_to_points — REPRCONV `keypoint` op

• Data kinds: keypoints → points

• Call: import reprconv; reprconv.keypoints_uv_to_points(keypoints, z=0.0) (or opsreprconv.get("keypoints_uv_to_points"))

Usage

Image coordinates `(N,2) = (u, v) → a point set (N,3) = (z, y, x). The exit from keypoints`.

op 名に軸の約束が書いてあるのは、この repo で `keypoints` を産む

`match3d.project_points が **(u, v) = (列, 行)** を返し、points` を産む

`fuse3d.to_points(voxel)` が (z, y, x) を返すから —— 素直に「先頭 2 列」

として繋ぐと例外も NaN も出ないまま行と列が入れ替わる。ここでは

`y = v、x = u` と明示的に入れ替えて渡す。

:func:points_zyx_to_keypoints_uv と往復して bit 一致(z を渡した向き)。

Args:

keypoints: (N, 2) の (u, v)。

z: 載せる平面の z(スカラ、または (N,) の配列)。

Returns:

(N, 3) float64 の (z, y, x)。

Raises:

ValueError: 形状不正 / 非有限 / z の長さ不一致。
