Describes a detected trapezoidal area (a candidate for a marker match).
After marker detection, a number of trapezoidal areas in the camera image will have been identified. An ARMarkerInfo struct is returned for each area so matched. Trapezoidal areas which have been matched with marker images (in pattern mode) or barcodes (in matrix mode) will have valid values assigned to the appropriate id field.
| int ARMarkerInfo::area |
Area in pixels of the largest connected region, comprising the marker border and regions connected to it. Note that this is not the same as the actual onscreen area inside the marker border.
| ARdouble ARMarkerInfo::cf |
If pattern detection mode is either pattern mode OR matrix but not both, will be marker matching confidence (range 0.0 to 1.0 inclusive) if marker is valid, or -1.0 if marker is invalid.
| ARdouble ARMarkerInfo::cfMatrix |
If pattern detection mode includes a matrix mode, will be marker matching confidence (range 0.0 to 1.0 inclusive) if marker is valid, or -1.0 if marker is invalid.
| ARdouble ARMarkerInfo::cfPatt |
If pattern detection mode includes a pattern mode, will be marker matching confidence (range 0.0 to 1.0 inclusive) if marker is valid, or -1.0 if marker is invalid.
| AR_MARKER_INFO_CUTOFF_PHASE ARMarkerInfo::cutoffPhase |
If a trapezoidal region is detected, but is eliminated from the candidates for tracking, this field is filled out with the tracking phase at which the marker was cut off. An English-language description of the phase can be obtained by indexing into the C-string array arMarkerInfoCutoffPhaseDescriptions[].
| int ARMarkerInfo::dir |
If pattern detection mode is either pattern mode OR matrix but not both, and id != -1, will be marker direction (range 0 to 3, inclusive).
| int ARMarkerInfo::dirMatrix |
If pattern detection mode includes a matrix mode, and id != -1, will be marker direction (range 0 to 3, inclusive).
| int ARMarkerInfo::dirPatt |
If pattern detection mode includes a pattern mode, and id != -1, will be marker direction (range 0 to 3, inclusive).
| int ARMarkerInfo::errorCorrected |
For marker types including error detection and correction, the numbers of errors detected and corrected.
| uint64_t ARMarkerInfo::globalID |
If arPattDetectionMode is a matrix mode, matrixCodeType is AR_MATRIX_CODE_GLOBAL_ID, and idMatrix >= 0, will contain the globalID.
| int ARMarkerInfo::id |
If pattern detection mode is either pattern mode OR matrix but not both, will be marker ID (>= 0) if marker is valid, or -1 if invalid.
| int ARMarkerInfo::idMatrix |
If pattern detection mode includes a matrix mode, will be marker ID (>= 0) if marker is valid, or -1 if invalid.
| int ARMarkerInfo::idPatt |
If pattern detection mode includes a pattern mode, will be marker ID (>= 0) if marker is valid, or -1 if invalid.
| ARdouble ARMarkerInfo::line[4][3] |

| ARMarkerInfo2* ARMarkerInfo::markerInfo2Ptr |
Pointer to source region info for this marker.
| ARdouble ARMarkerInfo::pos[2] |
2D position (in camera image coordinates, origin at top-left) of the centre of the marker.
| ARdouble ARMarkerInfo::vertex[4][2] |
2D positions (in camera image coordinates, origin at top-left) of the corners of the marker. vertex[(4 - dir)%4][] is the top-left corner of the marker. Other vertices proceed clockwise from this. These are idealised coordinates (i.e. the onscreen position aligns correctly with the undistorted camera image.)
