marker_match_grow — DRIVE `tacslip` op

• Data kinds: matrix × matrix × scalar → table

• Call: import fullseye as fs; fs.ledger.marker_match_grow(p0, p1, pitch_px: 'float', seed_tol: 'float' = 0.25, tols=(0.2, 0.3, 0.45), nb_r: 'float' = 1.6, border: 'float' = 2.0, max_iter: 'int' = 80) -> 'dict' (to call the implementation directly, import tacslip; tacslip.marker_match_grow(p0, p1, pitch_px: 'float', seed_tol: 'float' = 0.25, tols=(0.2, 0.3, 0.45), nb_r: 'float' = 1.6, border: 'float' = 2.0, max_iter: 'int' = 80) -> 'dict'; from the registry, opsdrive.get("marker_match_grow"))

Usage

Finds the correspondence between reference markers p0 and loaded markers p1 (each (N, 2) [px]) by growing it through continuity. Returns i0, i1 (index arrays of the correspondence) and matched.

規則格子では |u| がピッチ/2 を超えると最近傍も相関も隣のマーカーに飛ぶ(実測: 8 px 格子で 5 px のずれを PIV は −3 px と読む)。種 = p0 の外接矩形の縁(border·ピッチ以内)にあるマーカーで、予測なしの最近傍が seed_tol·ピッチ以内かつ 2 番目が 0.75 ピッチより遠いもの(「接触は視野の内側にあり縁は遠方場 = 小変位」という物理の前提。どこでも種にすると、核の変位 6.4 px が隣の基準位置から 1.6 px なのでピッチ 1 つ飛んだ偽の種が 27 個できた)。以後、未対応のマーカーは nb_r·ピッチ以内の既対応 2 点以上の変位の平均を予測にして tol·ピッチ以内の最近傍を取り、tol は小さい値から段階的に緩める。1 つの p1 は 1 回しか使わない。Raises ValueError: p0/p1 が (N, 2) でない、pitch_px ≤ 0。
