The invention discloses an automatic detection method for a large transfusion 
production line, including the following steps: 1, making a transfusion 
bottle filled with liquid 
medicine rotate in a high-speed, then rapidly stopping the transfusion 
bottle, so that the liquid 
medicine in the 
bottle has a self-rotating movement under the 
inertia; 2, picking-up a plurality of images of the transfusion bottle in which the liquid 
medicine is in a self-rotating state; 3, respectively digitally 
processing and mutually comparing to the plurality of images, distinguishing the exogenous 
impurity in the liquid medicine, in order to judge whether the bottle of liquid medicine is qualified. The invention also discloses an automatic detection apparatus for a large transfusion 
production line, which is characterized by including a rotation device, a controller, a 
video camera and an 
image processing apparatus, wherein, the output end of the controller is connected with the control terminal of the rotation device, a gripping device for fixing up the transfusion bottle, a rotating work 
station and a detecting work 
station are provided on the rotation device, and the 
video camera outputs data to the 
image processing apparatus. The invention can automatically detect whether 
impurity exists in the liquid medicine, with high testing accuracy and fast testing velocity.
