'**SUMMARY**
loadCalibration is a method to load the StereoCalibration parameters such as CM1, CM2, D1, D2, R, T, E, F of stereo pair.
This method loads from calibration files and return calibration on success else return false.
**PARAMETERS**
fname - is the prefix of the calibration files.
dir - is the directory in which files are present.
**RETURNS**
a tuple of the form (CM1, CM2, D1, D2, R, T, E, F) on success.
CM1 - Camera Matrix for left camera
CM2 - Camera Matrix for right camera
D1 - Vector of distortion coefficients for left camera
D2 - Vector of distortion coefficients for right camera
R - Rotation matrix between the left and the right camera coordinate systems
T - Translation vector between the left and the right coordinate systems of the cameras
E - Essential matrix
F - Fundamental matrix
else returns false
**EXAMPLE**
>>> StereoCam = StereoCamera()
>>> loadedCalibration = StereoCam.loadCalibration(fname="Stereo1")'

def loadCalibration(self, fname='Stereo', dir='.'):

    filenames = ((fname + 'CM1.txt'), (fname + 'CM2.txt'), (fname + 'D1.txt'), (fname + 'D2.txt'), (fname + 'R.txt'), (fname + 'T.txt'), (fname + 'E.txt'), (fname + 'F.txt'))
    try:
        CM1 = cv.Load('{0}/{1}'.format(dir, filenames[0]))
        CM2 = cv.Load('{0}/{1}'.format(dir, filenames[1]))
        D1 = cv.Load('{0}/{1}'.format(dir, filenames[2]))
        D2 = cv.Load('{0}/{1}'.format(dir, filenames[3]))
        R = cv.Load('{0}/{1}'.format(dir, filenames[4]))
        T = cv.Load('{0}/{1}'.format(dir, filenames[5]))
        E = cv.Load('{0}/{1}'.format(dir, filenames[6]))
        F = cv.Load('{0}/{1}'.format(dir, filenames[7]))
        print "Calibration    files    loaded    from    dir    '{0}'.".format(dir)
        return (CM1, CM2, D1, D2, R, T, E, F)
    except:
        return False
