nicetoolbox.detectors.method_detectors.sam_3d_body.sam_3d_body_stereo_triangulation

Two-view stereo triangulation for SAM 3D Body body_joints exports.

Functions

apply_stereo_triangulation_to_body_joints_payload	Replace primary 3d with stereo triangulation when enabled.
calibration_usable_for_stereo_triangulation	Intrinsics and projection for the first two cameras.
prepare_2d_for_triangulation	Low-confidence 2D coords → NaN, then temporal interpolation (pose_utils.interpolate_data).
triangulate_stereo_body_joints_from_two_cameras	Stereo 3d column (n_sub, 1, n_frames, n_kp, 4); NaN when subject missing in either camera.

Replace primary 3d with stereo triangulation when enabled. Returns True if applied.

nicetoolbox.detectors.method_detectors.sam_3d_body.sam_3d_body_stereo_triangulation.calibration_usable_for_stereo_triangulation(calibration: dict[str, Any] | None, camera_names: list[str]) → bool

Intrinsics and projection for the first two cameras.

nicetoolbox.detectors.method_detectors.sam_3d_body.sam_3d_body_stereo_triangulation.prepare_2d_for_triangulation(arr_2d: ndarray, min_confidence: float) → ndarray

Low-confidence 2D coords → NaN, then temporal interpolation (pose_utils.interpolate_data).

Stereo 3d column (n_sub, 1, n_frames, n_kp, 4); NaN when subject missing in either camera.
