Industrial OCR Peter Rogelj University of Ljubljana, Slovenia Faculty of electrical engineering Our OCR system is intended for use in industrial applications. It was primarily designed for reading of serial numbers of electricity meters but now it is appropriate for use in a wide range of industrial OCR applications such as reading of various types of serial numbers and notes on packing material. With some modifications it could also be used for other purposes such as reading of car licence plates. Because of it's industrial orientation there is a special focus on reliability and robustness. The overall process consists of five processing setps. These are Image grabbing, preprocesssing, character segmentation and postprocessing. All the steps have some influence on robustness.

Upper bearing is a part of watt-hour meter on which an aluminium plate rotates under the influence of current and voltage. The bearing consists of a hollow cylinder with a needle in the center that is fixed to the bottom. The system allows noncontact measurement of eccentricity of the bearing and the length of the needle extending out of the cylinder. It comprises personal computer, a black and white CCD camera, illumination and mechanical device with two stepper motors. The system is also able to straighten the needle if the eccentricity is out of tolerances. Results indicate that the proposed system alows accurate, reproductable and robust inspection and such it may be a valuable tool for ensuring high-end-product quality.
