Research Of Current Information Card Recogontion

Purpose of subject is to set up a automatic discriminating system for information card by software automatically to come totally. The information card automatic recognition system that this text developed has finished the formulation from the information card, the computer discern to that discerns that the result counts the whole course exported.In the formulation part of the information card, we connect a small-scale Chinese character system at first --Heaven remits the standard Chinese character system, solved the introduction problem of Chinese characters under DOS. And imitate the composing rule of Word, carry on the automatic composing to the information card content that is input, have offered the unified localization mode and essential characteristic data for discernment for the future.At pretreatment stage, we utilize the shape projection law of the post to make a reservation to the information card wholly, and deal with through rotation, translation to the picture, etc., correct to the information card, ready for following discernment. When discerning, system this propose one relative displacement law come position discerned to confirm, and utilize the repeated experiment to confirm a judgement threshold value as the standard that is discerned.In the last part of the system, we also put the result discerned in order to count, it is convenient for user to understand the whole situation of investigating.This systematic hardware part is made up of scanner, computer and printer; It finishes by C to realize the procedure.
