Visual inspection of watermeters used for automatic calibration
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 pattern recognition 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.
