Fiducial

class Fiducial(id: int, corners: ndarray, K: ndarray | None = None, rvec: ndarray | None = None, tvec: ndarray | None = None, p3d: ndarray | None = None)

Properties of a visual fiducial marker

Parameters:

• id (int) – identity of the marker

• corners (ndarray(2, 4)) – image plane marker corners

• K (ndarray(3,3), optional) – camera intrinsics

• rvec (ndarray(3), optional) – translation of marker with respect to camera, as an Euler vector

• tvec (ndarray(3), optional) – translation of marker with respect to camera
