Machine vision-based penicillin bottle logarithm counting system and method

The invention discloses a penicillin bottle logarithm counting system and method based on machine vision. The system comprises a bottle washing procedure, a bottle arranging procedure, a tunnel drying oven procedure, a filling procedure, a sealing procedure and a labeling procedure which are sequentially assembled in a matched mode, cameras are arranged in the bottle washing procedure, the bottle arranging procedure, the tunnel drying oven procedure, the filling procedure, the sealing procedure and the labeling procedure, and a control platform is arranged outside the cameras. According to the invention, rapid logarithm counting of penicillin bottles can be realized; an original image collected by a camera is subjected to filtering processing through a filtering module and then subjected to Laplace transformation, the transformed image is subjected to Hough change circle detection, and the number of circles is detected; the camera performs image acquisition on the penicillin bottle from the eccentric position
