change_radial_distortion_image — MV resample op

• Data kinds: image2d × table × table → image2d

• Call: import fullseye as fs; fs.ledger.change_radial_distortion_image(image, cam_in, cam_out, fill=0.0) (to call the implementation directly, import mvimage; mvimage.change_radial_distortion_image(image, cam_in, cam_out, fill=0.0); from the registry, opsmv.get("change_radial_distortion_image"))

• HALCON equivalent: change_radial_distortion_image (the HALCON reference is a useful guide to its meaning and parameters)

• GPU: none (CPU reference implementation only)

Usage

Redraw an image from one division-model camera into another distortion and intrinsics.

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

cam_out の画素を歪み除去 → 正規化座標 → cam_in の焦点距離 → cam_in の歪みの順に写して読む。kappa の単位は 1/画素^2 で、主点からの画素座標に掛かる。cam_out の kappa を 0 にすると歪み除去になる。空の入力(image が 0 要素)は ValueError。

Args:

image: (H, W) の画像。

cam_in: 入力のカメラ(fx / fy / cx / cy / kappa)。

cam_out: 出力のカメラ(同じ鍵)。

fill: 入力の外の画素の値。

Returns:

入力と同じ形の float 画像。

Detailed usage guide

• machine_vision_classics family guide

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.

Runnable examples (verified samples that actually call this op)

• machine_vision_tour — py -3.11 examples/machine_vision_tour.py

• poc_real_chessboard_undistort — py -3.11 examples/poc_real_chessboard_undistort.py
