Beschreibungen/Notizen
Large Industrial Computed Tomography (LICT) system is a key project granted by National Natural Science Fund and also a key project of 985 top-class university construction. It has a great significance for national defence and discipline development. The technology of auto defect recogniation of workpiece is a crucial part of this system. CT can supply multi-slice image data with high degree of accuracy, which can give ample data information for defect recognition. The main purpose of this project is to excogitate three-dimension defect analysis and processing technic suitable for solid-propellant rocket engine with three-dimension data acquired by LICT. The research production of this technic will solve the applied difficulties of defect fast location, reconstruction, display and quantitative measurement in LICT system used for solid-propellant rocket engine, which has a great meaning to accelerate the wide implementation of large nondestructive examination facilities and to ensure high-quality national defe
