Constant methods for crate::objdetect::CharucoBoard

Required Methods§

Source

fn as_raw_CharucoBoard(&self) -> *const c_void

Provided Methods§

Source

fn get_chessboard_corners(&self) -> Result<Vector<Point3f>>

get CharucoBoard::chessboardCorners

Source

fn get_nearest_marker_idx(&self) -> Result<Vector<Vector<i32>>>

get CharucoBoard::nearestMarkerIdx, for each charuco corner, nearest marker index in ids array

Source

fn get_nearest_marker_corners(&self) -> Result<Vector<Vector<i32>>>

get CharucoBoard::nearestMarkerCorners, for each charuco corner, nearest marker corner id of each marker

Source

fn check_charuco_corners_collinear( &self, charuco_ids: &impl ToInputArray, ) -> Result<bool>

check whether the ChArUco markers are collinear

§Parameters

charucoIds: list of identifiers for each corner in charucoCorners per frame.

§Returns

bool value, 1 (true) if detected corners form a line, 0 (false) if they do not. solvePnP, calibration functions will fail if the corners are collinear (true).

The number of ids in charucoIDs should be <= the number of chessboard corners in the board. This functions checks whether the charuco corners are on a straight line (returns true, if so), or not (false). Axis parallel, as well as diagonal and other straight lines detected. Degenerate cases: for number of charucoIDs <= 2,the function returns true.
