Concatenation of Machine Vision Inspection Results

Abstract

A vision-based product inspection system captures multiple images of each of multiple individual instances of a product as each instance passes through various phases of a production process. The system includes multiple cameras with each camera situated at a known location along a moving conveyor, conveyor belt, production line, or assembly line that moves instances of the product through various phases of the production process. Each camera can be associated with a known location along the conveyor and each image can be associated with a value representing the position of the conveyor as it moves product. Based on each camera's location and the values representing the conveyor's position, a sequence of images can be accumulated representing the progression of any single instance of a product as it moves through the production process. Automated quality control inspection can be performed by comparing or analyzing images in the sequence.
