To be acceptable in industry, automatic visual inspection systems must be inexpensive, very accurate and should be flexible enough to accommodate changes in products. This flexibility can be reached if a modular concept that allows a quick and inexpensive adaption of the inspection process to any changes is used. This paper presents a concept where the detection of primitives is separated from the model-based analysis process. Existing patternrecognition software is re-used in the detection stage, allowing any detection algorithm to be tested and used without changing the analysis process. The visual inspection of analog watermeters serves for a demonstration of this concept.
