The present invention relates to a method of measuring an orbital volume using a facial computed tomography image and, more specifically, relates to a method of automatically and accurately extracting an optical boundary through a snake algorithm. The method of measuring an orbital volume using a facial computed tomography image comprises: (S1) a first step of extracting a plurality of facial computed tomography images (S2) a second step of filtering one of the images extracted in the first step (S1) (S3) a third step of binarizing the image processed in the second step (S2) (S4) a fourth step of processing a hole part by an infill function on the image processed in the third step (S3) (S5) a fifth step of detecting an unnecessary part from the image processed in the fourth step (S4) in accordance with a predetermined standard, and extracting an edge (S6) a sixth step of extracting an optical boundary from the image extracted in the fifth step (S5) (S7) a seventh step of calculating an area of the image extracted in the sixth step (S6) (S8) an eighth step of performing each of the first step (S1) to the seventh step (S7) with respect to the facial computed tomography images in the first step (S1) and (S9) a ninth step of calculating a volume using all areas of the image calculated in the seventh step (S7). The method of measuring an orbital volume from a facial computed tomography image using a computer program is able to measure the optical volume in a comparatively convenient and accurate manner without a special additional device.COPYRIGHT KIPO 2016본 발명은 얼굴전산화단층촬영이미지을 이용한 안와용적 측정법에 관한 것으로 보다 상세하게는 스네이크 알고리즘을 통하여 안와경계를 자동으로 정확하게 추출하기 위한 발명에 관한 것으로서, 다수의 얼굴전산화단층촬영이미지를 추출하는 제1단계(S1) 상기 제1단계(S1)에서 추출된 이미지 중 어느 하나의 이미지를 필터 처리하는 제2단계(S2)상기 제2단계(S2)에서 처리된 이미지를 2진화 처리하는 제3단계(S3) 상기 제3단계(S3)에서 처리된 이미지에서 임필(Imfill) 함수에 의한 홀(hole)부분을 처리하는 제4단계(S4) 상기 제4단계(S4)에서 처리된 이미지에서 미리 결정된 기준에 의해 불필요한 부분의 삭제 및 에지를 추출하는 제5단계(S5) 상기 제5단계(S5)에서 추출된 이미지에서 안와경계를 추출하는 제6단계(S6) 상기 제6단계(S6)에서
