project_hom_point_hom_mat3d — CALIB project op

• Data kinds: matrix → keypoints

• Call: import fullseye as fs; fs.ledger.project_hom_point_hom_mat3d(points_hom, hom_mat3d) (to call the implementation directly, import calib; calib.project_hom_point_hom_mat3d(points_hom, hom_mat3d); from the registry, opscalib.get("project_hom_point_hom_mat3d"))

• GPU: none (CPU reference implementation only)

Usage

Projects homogeneous 3-D points (4,) with a 3x4/4x4 projection matrix and returns pixels (row, col) (project_hom_point_hom_mat3d).

Detailed usage guide

• camera_calibration 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)
