Struct opencv::objdetect::ArucoDetector

pub struct ArucoDetector { /* private fields */ }

The main functionality of ArucoDetector class is detection of markers in an image with detectMarkers() method.

After detecting some markers in the image, you can try to find undetected markers from this dictionary with refineDetectedMarkers() method.

Basic ArucoDetector constructor

Parameters

• dictionary: indicates the type of markers that will be searched
• detectorParams: marker detection parameters
• refineParams: marker refine detection parameters

C++ default parameters

• dictionary: getPredefinedDictionary(cv::aruco::DICT_4X4_50)
• detector_params: DetectorParameters()

Trait Implementations

impl AlgorithmTrait for ArucoDetector

fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for ArucoDetector

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut FileStorage, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
