Image Processing Technique for Drilled Holes Inspection in Large Rectangular Plate
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 3
Abstract
Baffle plates used in power plants as heat exchangers for the process of condensation are huge in size with large volume of holes meant for inserting and supporting the bundles of condenser tubes are transported to the site, where the tubes assembly is carried out.. Incidentally if a hole is undersized, oversized or not drilled, to rectify the same it is extremely difficult to carry out such operations at site as an oversize hole will lead to tube vibrations leading to physical damages to the condenser tubes. This leads to requirement for inspection of drilled holes in large rectangular plate. At present holes are checked by hand gauges, GO / NOGO Gauges, which is manually carried out and also time consuming. This made a way for optical inspection which offers the desirable characteristics of being non-invasive and non destructive, able to analyze real time objects in a remote sense.The present paper describes an automated method using image processing technique, for measurement of the large number of holes and its parameters for reducing the cycle time of inspection and improve the hole parameter measurement process, in tube sheet or baffle plates.
