Erosion Measurement System for Turbine Blade

Abstract

Disclosed is an erosion measurement system for a turbine blade, including: a light illumination device for irradiating light to generate a brightness difference to distinguish a measurement region when inspecting a turbine blade; an optical image acquisition device for creating an image optically photographing a blade surface; and an image analysis and erosion amount calculation device for analyzing an image photographed by the optical image acquisition device and calculating an erosion amount of a blade, and the light illumination device and the optical image acquisition device are fixed to face each other with a target blade disposed at a center and photographing a target blade while moving relatively in a circumferential direction of a turbine, and the image analysis and erosion amount calculation device may calculate an erosion amount in a manner accumulating an erosion amount at a plurality of measurement locations located inside a blade.
