Image Analysis for Complex Data in Non-Destructive Testing (NDT)

Funding body

EPSRC (with industry partner TWI)


Principal investigator: Hongying Meng

Project description

This project follows on from a major European collaborative project focussed on whole life rail axle assessment and Improvement. It is based at the NSIRC in TWI, Cambridge.

Non-Destructive Testing (NDT) techniques are a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. TWI has been at the forefront of the research, development and application of many advanced and conventional NDT technologies for more than 40 years (http://www.twi-global.com/capabilities/integrity-management/non-destructive-testing/).

This project will develop image analysis techniques for rail axle inspection. Rail axles suffer from high cycle fatigue during operation and also corrosion due to the environment, which modifies the fatigue properties. In order to identify when the cracking process is beginning a microscope image of the axle surface has been used.

The project will take images (existing) from real axles which contain a mixture of corrosion and cracks and try to develop an image analysis technique to automate the identification of cracks within the corrosion.
