Expand description

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.

Required Methods§

Provided Methods§

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

Returns the distance of the input bits to the specific id.

If allRotations is true, the four posible bits rotation are considered

C++ default parameters
  • all_rotations: true

Generate a canonical marker image

C++ default parameters
  • border_bits: 1
