Defect Detection and Three Dimensional Reconstruction of Castings
School of Mechanical and Power Engineering, East China University of Science and Technology, Shanghai 200237, China
There are defects inevitably in the production of castings. These defects will short the life of castings. In this paper, defects of the castings are detected by industrial CT non-destructive testing method and a series of CT slice images are obtained. Then edge extraction is realized through the Canny operator and the defects in the castings are found. Finally, surfaces and its internal defects are reconstructed for the casting based on secondary development of Unigraphics software and Visual Studio 2013. Experiments show that internal defects of the castings can be extracted by the Canny operator effectively. Internal position and shape of defects can be observed directly by three dimensional reconstruction.
