Zusammenfassung:The present invention relates to a method to improve selection accuracy of a shoe sole, comprising: a step of photographing a shoe sole; a step of extracting an edge line of the shoe sole from a generated photographing image; a step of selecting the longest line and a plurality of measurement lines perpendicular to the longest line from lines connecting any two points among points forming the edge line; a step of calculating a length of the longest line and the measurement lines to acquire a calculation valve; and a step of determining quality of the shoe sole based on the calculation valve. According to the present invention, since the longest line and the measurement line are selected from the photographing image of the shoe sole and the lengths of the longest line and the measurement lines are calculated so as to determine the quality of the shoe sole, it is not required to detect a mark from the photographing image, thereby being able to apply a used mold or a mold being manufactured without processing the same. 본 발명은 신발 밑창 선별 정확도 향상 방법에 관한 것으로, 신발 밑창을 촬영하는 단계와, 생성된 촬영이미지에서 신발 밑창의 테두리선을 추출하는 단계와, 테두리선을 이루는 점들 중 어느 두 점을 잇는 선들로부터, 최장선과 최장선과 수직한 다수개의 계측선을 선정하는 단계와, 최장선과 다수개의 계측선의 길이를 산출해 산출값을 획득하는 단계와, 산출값을 근거로 신발 밑창의 품질을 판단하는 단계를 포함하며, 신발 밑창의 촬영이미지로부터 최장선 및 계측선을 선정하고, 최장선 및 계측선의 길이를 산출해 신발 밑창의 품질을 판단하게 되므로, 촬영이미지로부터 표식 검출이 불필요하며 이로 인해, 종래 사용되던 금형 또는 제작 중인 금형을 가공하지 않더라도 적용이 가능한, 신발 밑창 선별 정확도 향상 방법을 제공한다.
