The invention discloses an
assembly instruction quotation and text comparison method and
system, and relates to the technical field of computers. The
assembly instruction quotation and text comparison method comprises the steps that according to different
assembly instruction page attributes, pre-
processing preparation work before comparison is conducted on an assembly instruction compilation description page, a process
content page and a matching page; respectively generating a first comparison object, a second comparison object and a third comparison object corresponding to the assembly instruction compiling description page, the process
content page and the matching page, and carrying out character format separation, binarization
processing,
image noise reduction, tilt correction and character
feature extraction; performing pairwise comparison, and performing logic consistency check and formatting comparison after item-by-item comparison and
cross reference verification. The assembly instruction quotation and text comparison method and
system are not limited by the problems of
file size and file fuzziness, and the negligence, difference and omission phenomena of manual comparison of consistency before and after single document content are solved.
