Abstract

An image analysis method was developed for the inspection of rotating blades of steam turbines. The method consists of three parts: (1) detecting the eventual crack points, (2) locating the cluster of these points, i.e. the eventual crack and (3) following and analyzing the eventual crack. A computer vision system was constructed to implement the method. The system has been tested during shutdowns in a Finnish power plant.
