Public Member Functions
def	update (self)
	Update R (Camera rotation matrix), Proj (Projection matrix [R,t] and the Center coordinates in object reference frame.
def	read (self, in_dir, fisheye=False)
	get camera parameters from file
def	save (self, in_dir, fisheye)
	save camera parameters in file
def	get_checkpoints (self, out_dir, w, h, fisheye)
	gets checkboard points for the intrinsic camera calibration.
def	get_calibpoints (self, img, pattern_size, counter, out_dir, fisheye, save_input=True, save_output=True)
	returns pairs of object- and image points (chess board corners) for camera calibration
def	save_checkpoints_file (self, out_dir, n_cameras)
	take pictures and save them in out_dir for later processing
def	get_checkpoints_file (self, out_dir, w, h, fisheye, img='')
	gets checkboard points for the intrinsic camera calibration from pictures that have been taken previously (either in file structure or given as argument)
def	reposition (self, opts, ipts, flag=cv2.CV_P3P, ransac=0, err=8)
	Redefines the position vectors r and t of the camera given a set of corresponding image and object points Options: -guess for camera position (using rvguess function) -method: Iterative = 0, EPNP = 1, P3P = 2 -ransac method for solvepnp.
def	reposition_homography (self, opts, ipts)
	calculate Proj matrix following instructions of 'A Flexible New Technique for Camera Calibration' of Zhang, 2000.
def	check_imagepoints (self, p_obj, p_img)
	Returns images of reference points (known) and the relative error matrix.
def	ransac_loop (self, img, flag, repErr_range)
	Loops through values for reprojection Error tolerance (from repErr_range) and finds best fit based on error of reprojected reference points.
