Constructor

obj = cv.RotationWarper(warperType, scale)
obj = cv.RotationWarper(..., 'OptionName',optionValue, ...)

Input

• warperType image warper factory class type, used to create the rotation-based warper. One of:
  • PlaneWarper Plane warper factory class. Warper that maps an image onto the z = 1 plane.
  • AffineWarper Affine warper factory class. Affine warper that uses rotations and translations. Uses affine transformation in homogeneous coordinates to represent both rotation and translation in camera rotation matrix.
  • CylindricalWarper Cylindrical warper factory class. Warper that maps an image onto the x*x + z*z = 1 cylinder.
  • SphericalWarper Spherical warper factory class. Warper that maps an image onto the unit sphere located at the origin. Projects image onto unit sphere with origin at [0,0,0] and radius scale, measured in pixels. A 360 panorama would therefore have a resulting width of 2*scale*pi pixels. Poles are located at [0,-1,0] and [0,1,0] points.
