Increasing flexibility for automatic visual inspection: the general analysis graph

The continuing development of machine vision is initiating a change from human to machine vision for inspection purposes. This paper concentrates on a general analysis graph within a systematic automated visual inspection concept that speeds up the development of such systems by increasing the flexibility. The detection of primitives is separated from the model-based analysis process. Together with an object-specific description, the analysis graph is instantiated to perform the inspection. The analysis graph can be seen as a “recipe” for solving industrial applications, stating which kind of decisions have to be made at which stage.
