Claim 4:
5. The binarization method for CT sectional image of fiber package containing artifacts as claimed in claim 1, wherein in the step 6, the removing a background noise of the binarized image I4 to thereby obtain a final binarized image I5 specifically comprises:
performing, based on a command expressed in an expression 6.1, an image opening operation to delete each connected domain with an area less than P pixels from the binary image I4 to thereby obtain the final binarized image I5, where P is less than a minimum pixel value occupied by the optical fiber core after binarizing:

I5=bwareaopen(I4,P)  (expression 6.1).
