Struct opencv::objdetect::CharucoBoard

pub struct CharucoBoard { /* private fields */ }

ChArUco board is a planar chessboard where the markers are placed inside the white squares of a chessboard.

The benefits of ChArUco boards is that they provide both, ArUco markers versatility and chessboard corner precision, which is important for calibration and pose estimation. The board image can be drawn using generateImage() method.

Implementations

impl CharucoBoard

pub fn new( size: Size, square_length: f32, marker_length: f32, dictionary: &Dictionary, ids: &impl ToInputArray ) -> Result<CharucoBoard>

CharucoBoard constructor

Parameters

• size: number of chessboard squares in x and y directions
• squareLength: squareLength chessboard square side length (normally in meters)
• markerLength: marker side length (same unit than squareLength)
• dictionary: dictionary of markers indicating the type of markers
• ids: array of id used markers The first markers in the dictionary are used to fill the white chessboard squares.

C++ default parameters

• ids: noArray()

pub fn new_def( size: Size, square_length: f32, marker_length: f32, dictionary: &Dictionary ) -> Result<CharucoBoard>

CharucoBoard constructor

Parameters

• size: number of chessboard squares in x and y directions
• squareLength: squareLength chessboard square side length (normally in meters)
• markerLength: marker side length (same unit than squareLength)
• dictionary: dictionary of markers indicating the type of markers
• ids: array of id used markers The first markers in the dictionary are used to fill the white chessboard squares.

Note

This alternative version of [new] function uses the following default values for its arguments:

• ids: noArray()

pub fn default() -> Result<CharucoBoard>
