Application research of machine vision technique in intelligent empty bottle inspection system

Intelligent empty bottle inspection system is an indispensable inspection equipment of empty bottle before filling beer. It is a blend of machine vision, precision machine and real-time control. Machine vision is the hard core, which affect the speed and accuracy of the inspection. In this paper, the machine vision technology used in intelligent empty bottle inspection system is introduced, and the bottle mouth inspection unit is used as an example to present its hardware structure and software algorithm constitution, from two angles of image acquisition and image processing. Practical applications show that this machine vision system can acquire sharp images and process images with high speed and high accuracy, which can fully satisfy intelligent empty bottle inspection´s requirement.
