The paper describes an automatic on-line detecting system which can detect inner parts of complex electromechanical products. In the system
digital image processing technology is used to preprocess X-ray images of the products
and neural network algorithm is applied to diagnose faults. The fault recognition model adopts an improved back-propagating neural network
which is trained by a series of standard X-ray images of correctly assembled products.During the process of detection
two images of objects in different directions are capable of acquiring the status of the key parts. After comparing the features of the two preprocessed images and standard images
the network can estimate different types of faults of the key parts. The detecting system combines digital radiography technology with digital image processing
and applies the back-propagating neural network algorithm in the fault recognition process. The system improves the speed and reliability of fault detection and has practicability in the field of industrial nondestructive detection.
