Paper Sobel Operated Edge Detection Scheme Using Image Processing For Detection Of Metal Cracks

摘要

This paper is based on detection of surface-breaking cracks in metals. It is an issue in many industries. Earlier in case of detecting cracks and defects, eddy current and ultrasonic techniques were used. Some other methods were also been conducted using eddy currents and microwave methods. In every industry, the detection of defects and classification are based on a digital image and it is the key requirement in quality control system. Conventionally, humans were engaged for detecting defects but it was a time consuming task. But this process is time consuming. So an inspection system based on image processing is needed to be introduced. The main objective of the paper is to design a system based on image processing to detect the defects and cracks in a metal object. By using image processing for crack detection, a better and efficient solution to crack detection can be done.
