Abstract

본 발명은 물체의 방향성 감지 화상인식방법에 있어서, 특히 화상 인식장치로 화상인식시 작업자가 방향성을 갖는 이미지를 선택하여 물체의 위치보정기준을 정하는 방법으로, 기준위치와 180도 호전한 위치를 비교하여 화상인식부위의 이미지가 일정한 기준치에 비해 방향성을 확보하지 못할때는 다른곳을 재인식토록하여 방향성이 있는 부분을 이미지로 선택함으로써, 작업물체가 리버스 인풋되었을때 이는 정확히 감지하여 제품의 불량을 방지해주는 것으로, 이는 화상인식장치로 어떤물체를 인식하여 위치좌표 보정을 하는 머신에 적용가능하다.According to the present invention, in a method of detecting an orientation of an object, in particular, a method of determining an object position correction criterion by selecting an image having an orientation when an image is recognized by an image recognition device, and comparing the position improved by 180 degrees with the reference position. When the image of the image recognition part cannot secure the direction compared to a certain standard value, it recognizes the other part and selects the direction part as the image by re-recognizing the other part, so that it is accurately detected when the workpiece is reverse input and prevents product defects. This is applicable to a machine that recognizes an object with an image recognition device and corrects position coordinates.

리드프레임의 리버스 인풋을 방지하기 위한 화상인식 방법Image recognition method to prevent reverse input of leadframe

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

제2도는 본 발명을 설명하기 위한 예시도.2 is an exemplary view for explaining the present invention.

Claims (1)

CCD카메라와, 화상처리부 및 디스플레이수단으로 이루어지는 화상 인식수단으로 대각선방향의 티칭값을 구하여 리드프레임의 리버스 인풋을 방지토록하는 화상인식방법에 있어서, 화상인식수단에 의하여 최초 대각선방향으로 티칭값은 구하고 난후 그위에 180도를 회전한 화상을 대비시키는 제1단계와; 상기 제1단계 수행후 티칭 최초위치와 180도 회전한 티칭위치를 비교한 매칭값이 차이가 날때는 구한 티싱값을 화상인식수단에 메모리하고, 매칭값이 차이가 나지 않을때는 다른 블럭의 화상을 재티칭하여 제1단계를 반복하는 제2단계를 순차동작함을 특징으로 하는 리드프레임의 리버스 인풋을 방지하기위한 화상인식 방법.In the image recognition method of preventing the reverse input of the lead frame by obtaining a teaching value in the diagonal direction by an image recognition means comprising a CCD camera and an image processing unit and a display means, the teaching value is obtained in the initial diagonal direction by the image recognition means. A first step of contrasting the image rotated thereafter by 180 degrees; When the matching value comparing the teaching position and the teaching position rotated 180 degrees after the first step is different, the acquired teaching value is stored in the image recognition means, and when the matching value is not different, the image of another block is displayed. And re-teaching a second step of repeating the first step, in order to prevent reverse input of the lead frame. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
