}

Describes a detected trapezoidal area (a candidate for a marker match).

This serves as the primary output of marker detection. It contains both raw properties of the shape (area, pos) and, if successfully matched, the identified marker ID and viewing direction.

Fields

area: i32

Area in pixels of the largest connected region.

id: i32

Marker ID if valid, or -1 if invalid (global ID regardless of matching type).

id_patt: i32

Template marker ID if matched via template matching, -1 otherwise.

id_matrix: i32

Matrix (barcode) marker ID if matched via matrix code, -1 otherwise.

dir: i32

Orientation of the marker (0, 1, 2, or 3) representing rotation in 90° increments.

dir_patt: i32

Orientation if matched via template matching.

dir_matrix: i32

Orientation if matched via matrix code.

cf: ARdouble

Confidence value of the match (0.0 to 1.0).

cf_patt: ARdouble

Confidence value from template matching.

cf_matrix: ARdouble

Confidence value from matrix code decoding.

pos: [ARdouble; 2]

Center of the marker (2D coordinate).

line: [[ARdouble; 3]; 4]

Line equations of the four sides of the marker in 2D space [a, b, c].

vertex: [[ARdouble; 2]; 4]

2D coordinates of the four corners in ideal (undistorted) camera space.

marker_info2_ptr: *mut ARMarkerInfo2

Pointer to source region info for this marker.

cutoff_phase: ARMarkerInfoCutoffPhase

Tracking phase at which the marker was cut off

error_corrected: i32

The numbers of errors detected and corrected

global_id: u64

Global ID for matrix codes
