The invention discloses a method for detecting ampoule bottle appearance quality through a medical visual inspection robot. The method comprises the steps of (1) acquiring an ampoule bottle image, and preprocessing the image through a median filter; (2) solving an ampoule bottle mimic symmetry line by employing a threading method to obtain a rotating angle alpha; (3) rotating the image by using a bilinear interpolation-summation method; (4) solving a symmetry center line, wherein the intersection of the symmetry center line and the head is a symmetry center point h0; (5) solving a head edge point; (6) enabling the outer curve at the head of the ampoule bottle to have the characteristic of a symmetrical variable trend in a lower parabola shape, and judging whether the ampoule bottle appearance wire-drawing quality is qualified; (7) positioning a black head detection rectangular area; (8) judging whether the black head ampoule bottle appearance is qualified by employing a difference method; and (9) integrating
