Expand description

Fit quality metrics for a detected marker.

Reports the edge sampling and ellipse fit quality. High RANSAC inlier ratios (> 0.8) and low RMS Sampson residuals (< 0.5 px) indicate a precise ellipse fit.

Fields§

§n_angles_total: usize

Total number of radial rays cast.

§n_angles_with_both_edges: usize

Number of rays where both inner and outer ring edges were found.

§n_points_outer: usize

Number of outer edge points used for ellipse fit.

§n_points_inner: usize

Number of inner edge points used for ellipse fit.

§ransac_inlier_ratio_outer: Option<f32>

RANSAC inlier ratio for outer ellipse fit.

§ransac_inlier_ratio_inner: Option<f32>

RANSAC inlier ratio for inner ellipse fit.

§rms_residual_outer: Option<f64>

RMS Sampson residual for outer ellipse fit.

§rms_residual_inner: Option<f64>

RMS Sampson residual for inner ellipse fit.

§max_angular_gap_outer: Option<f64>

Maximum angular gap (radians) between consecutive outer edge points.

§max_angular_gap_inner: Option<f64>

Maximum angular gap (radians) between consecutive inner edge points.

§inner_fit_status: Option<InnerFitStatus>

Inner fit outcome: "ok", "rejected", or "failed". Absent when fit succeeded without issue.

§inner_fit_reason: Option<InnerFitReason>

Inner fit rejection reason code. Present only when inner_fit_status is "rejected" or "failed".

§neighbor_radius_ratio: Option<f32>

Ratio of this marker’s outer radius to the median outer radius of its k nearest decoded neighbors. Values well below 1.0 (< 0.75) indicate a potential inner-as-outer substitution. Populated in the finalization stage.

§inner_theta_consistency: Option<f32>

Theta consistency score from the inner estimate stage. Fraction of theta samples that agree on the inner edge location. Present when estimation ran, including when it failed the quality gate.
