stereo op• Data kinds: image2d × image2d → table
• Call: import fullseye as fs; fs.ledger.binocular_disparity_ms(left, right, max_disp=32, window=5, P1=5.0, P2=50.0, paths=4, lr_tolerance=1.0) (to call the implementation directly, import mvstereo; mvstereo.binocular_disparity_ms(left, right, max_disp=32, window=5, P1=5.0, P2=50.0, paths=4, lr_tolerance=1.0); from the registry, opsmv.get("binocular_disparity_ms"))
• HALCON equivalent: binocular_disparity_ms (the HALCON reference is a useful guide to its meaning and parameters)
• GPU: none (CPU reference implementation only)
Compute rectified-stereo disparity with semi-global matching, verify it left-right and interpolate to subpixel.
> The detailed description below is the original text — the summary and the headings are translated.
左基準と右基準の視差を stereo.disparity_sgm で 1 回ずつ計算し、対応点で lr_tolerance より食い違う画素と参照できない左端の列を無効にする。残りの画素は SAD の 3 点放物線で小数の視差へ補間する。無効の画素は disparity が NaN になる。空の入力(left が 0 要素)は ValueError。
Args:
left: 左の画像 (H, W)。視差はこの画像を基準にする。
right: 右の画像 (H, W)。
max_disp: 探す視差の上限(画素、>= 1)。
window: census と SAD の窓(奇数)。
P1: 視差 1 の段差の罰則。
P2: 視差 2 以上の段差の罰則。
paths: 集約の方向数(2 / 4)。
lr_tolerance: 左右一致の許容差(画素)。
Returns:
disparity(float、無効は NaN)、valid(bool)、score(0..1、大きいほど
コストの谷が深い)を持つ dict。
