Struct opencv::aruco::Dictionary

pub struct Dictionary { /* fields omitted */ }

Dictionary/Set of markers. It contains the inner codification

bytesList contains the marker codewords where

• bytesList.rows is the dictionary size
• each marker is encoded using nbytes = ceil(markerSize*markerSize/8.)
• each row contains all 4 rotations of the marker, so its length is 4*nbytes

bytesList.ptr(i)[k*nbytes + j] is then the j-th byte of i-th marker, in its k-th rotation.

Trait Implementations

impl Boxed for Dictionary

pub unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

pub fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

pub fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

pub fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl DictionaryTrait for Dictionary

pub fn as_raw_Dictionary(&self) -> *const c_void

pub fn as_raw_mut_Dictionary(&mut self) -> *mut c_void

pub fn bytes_list(&mut self) -> Mat

pub fn set_bytes_list(&mut self, val: Mat)

pub fn marker_size(&self) -> i32

pub fn set_marker_size(&mut self, val: i32)

pub fn max_correction_bits(&self) -> i32

pub fn set_max_correction_bits(&mut self, val: i32)

pub fn identify(
    &self,
    only_bits: &Mat,
    idx: &mut i32,
    rotation: &mut i32,
    max_correction_rate: f64
) -> Result<bool>

Given a matrix of bits. Returns whether if marker is identified or not. It returns by reference the correct id (if any) and the correct rotation

    &self,
    bits: &dyn ToInputArray,
    id: i32,
    all_rotations: bool
) -> Result<i32>

Returns the distance of the input bits to the specific id. If allRotations is true, the four posible bits rotation are considered

    &self,
    id: i32,
    side_pixels: i32,
    _img: &mut dyn ToOutputArray,
    border_bits: i32
) -> Result<()>
