Abstract
A method for reading a bar code digitally records a two-dimensional low resolution image by a camera. A modified Hough Transform obtains vote counts on lines relative to a reference point. The votes are clustered to obtain the bin axis of the bar code. The decoding step of the bar code uses an intensity profile along the bin direction. An apparatus for accomplishing the above method is also set out.
