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

제 1 도는 본 발명의 한 예의 계통도. 제 2 도 내지 제12도는 그 설명을 위한 도면.1 is a schematic diagram of an example of the invention. 2 to 12 are diagrams for explanation thereof.

Claims (1)

식별의 기준이 되는 마스터패턴 및 식별의 대상이 되는 대상패턴의 비데오신호를 2치신호로 변환하는 2치화회로와, 상기 2치신호를 스토어하는 프레임 메모리와 상기 마스터패턴의 무게중심 및 관성주축을 계산하는 수단과, 상기 마스터패턴의 화상을 표시하고 있는 화면상의 임의의 위치에 카솔을 설정하는 설정수단과, 상기 마스터패턴의 2치신호중, 상기 설정수단으로 설정된 카솔위치에 대응하는 신호로 그 카솔위치의 흑백정보를 마스터 데이타로서 등록하는 수단과, 상기 대상패턴의 무게중심 및 관성주축을 계산하는 수단과, 상기 대상패턴의 2치신호중, 상기 카솔위치에 대응하는 신호로부터 그 카솔위치의 흑백정보를 대상 데이타로서 추출하는 수단과, 이 대상 데이타와 상기 마스터 데이타를 비교하는 비교수단과, 이 비교수단의 비교출력에 기준해서 상기 식별의 대상이 되는 대상패턴에 관한 식별 결과를 출력하도록한 것을 특징으로 하는 2치 화상처리에 의한 식별장치.A binarization circuit for converting the video signal of the master pattern and the target pattern to be identified into a binary signal, a frame memory storing the binary signal, a center of gravity of the master pattern, and an inertia spindle Means for calculating, setting means for setting the casing at an arbitrary position on the screen displaying the image of the master pattern, and a signal corresponding to the casing position set by the setting means among the binary signals of the master pattern. Means for registering the black-and-white information of the position as master data, means for calculating the center of gravity and the inertia axis of the target pattern, and black-and-white information of the casol position from a binary signal of the target pattern, the signal corresponding to the car-sole position; Means for extracting the data as the target data, comparison means for comparing the target data with the master data, and a comparison output of the comparison means. And an identification result relating to a target pattern to be identified as a reference. ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
