ABSTRACT:
A system and method for inspecting a moving container on a conveyor. An encoder assembly detects movement of the conveyor and generates a signal representative of the speed of the container as a function of the movement of the conveyor. A light source adjacent the conveyor illuminates the container and a camera adjacent the conveyor generates a plurality of successive images of portions of the illuminated container. The images each include a plurality of pixels, each having a value representative of an optical characteristic of the images. The camera is controlled to generate the successive images as a function of the speed of the moving container. An image processor acquires a two-dimensional image of the container from the successive images generated by the camera and processes the two-dimensional image as a function of the pixel values to detect edges in the image for inspecting the container.
