광학 문자 판독기의 문자 분류 처리방법Character Classification Method in Optical Character Reader

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명 광학 문자 판독기의 문자 분류 처리시스템 구성도,1 is a block diagram of a character classification processing system of the optical character reader of the present invention;

제2의 (가)(나)는 제1도의 이미지 스캐너로 주사한 문자를 메시로 나누어 분류처리하는 예시 설명도.2 (a) (b) is an exemplary explanatory diagram for classifying the characters scanned by the image scanner of FIG. 1 into meshes.

Claims (1)

이미지 스캐너(1)와 마이컵(2) 및 데이타램(3)으로 구성된 광학 문자 판독기의 문자인식에 있어서, 상기 마이컴(2)은 이미지 스캐너(1)로 부터 주사된 문자 이미지를 입력하여 그 문자 이미지에 외접하는 박스를 구성하고, 그 박스를 임의의 갯수로 결정하여 등간격으로 메시를 구성한 다음 각 메시내에 포함된 화소수를 임계값과 비교하여 메시값을 구하고, 이후 문자의 메시를 기준으로 상, 하 좌우에서 본훨의 거리를 백터로 계산한 다음 데이타램(3)에 저장된 기준데이타와 비교하여 임계값 이내에 포함된 문자를 분류 처리하는 것을 특징으로 한 광학 문자 판독기의 문자 분류 처리방법In the character recognition of the optical character reader composed of the image scanner 1 and the micup 2 and the data ram 3, the microcomputer 2 inputs the character image scanned from the image scanner 1 and inputs the character. Construct a box that circumscribes the image, determine the number of boxes at random, and construct the mesh at equal intervals, and then compare the number of pixels in each mesh with the threshold to obtain a mesh value. Character classification processing method of the optical character reader, characterized by calculating the distance of the bones from the top, bottom, left and right as a vector and then comparing the reference data stored in the data RAM 3 to classify the characters contained within the threshold value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
