Detection of empty beer bottle impurity was realized based on Canny algorithm, by using CCD sensor to obtain the image of empty bottle, pretreating the image, and calculating the threshold of the Canny algorithm with Otsu algorithm. Canny algorithm was introduced into the detection process of empty beer bottle＇s impurity, and the detection method was validated by experiment. It was concluded that Canny algorithm can enhance the veracity of impurity detection, and redound to the development of beer bottle＇s on -line automatic detection.
