カメラと役割

camera_front           static
camera_top             static
camera_left_wrist      wrist
camera_right_wrist     wrist

role=none のカメラは格子が全ゼロで、注入対象から外れる。

チャネル定義

0 CH_VALUE   static: 盤面相対高さ[m] の 95%tile / wrist: 指先相対 Δ[m] の 5%tile
1 CH_OCC     セル内で「盤面から浮いている / 指先近傍にある」画素の割合
2 CH_SPREAD  セル内の奥行き幅 q95-q05[m]
3 CH_VALID   有効画素率 (0-1)。0 は欠測であって「盤面上(d=0)」ではない

precompute が出した警告

  • observation.images.camera_front の深度スケールがフレーム間で std 74 mm 揺れています。ゲージ正規化で吸収していますが、ROI に腕が入りすぎている可能性があります。
  • observation.images.camera_front の平面インライア率が 38% しかありません。--roi が板から外れているか、ROI に腕/治具が入っています。
  • observation.images.camera_left_wrist は --metric 申告のバックボーンですが、実測 a0 との比較で スケールが x0.42 でした(30%以上ずれ)。近距離での metric申告が信用できないことを示すので、他のカメラでも実測での裏取りを推奨します。
  • observation.images.camera_right_wrist は --metric 申告のバックボーンですが、実測 a0 との比較で スケールが x0.43 でした(30%以上ずれ)。近距離での metric申告が信用できないことを示すので、他のカメラでも実測での裏取りを推奨します。
