Three-dimensional Reconstruction of Serial Industrial Computed Tomography Images

The three-dimensional(3-d) reconstruction and visualization of serials of industrial computed tomography(ICT) images is an important research aspect for large objects nondestructive detection. In the course of 3-d reconstructions of the continuous equidistant ICT images, the contour lines of every tomogram are picked out and joint by triangles in serialized order. After the stereo images of the scanned objects are displayed, some special functions, including views from different angles and orientations, nondestructive measurement of 3-d parameters, will be carried out just by operating the computer mouse and keyboard. The inspectors can get more detailed structural information by the reconstructed images. So in this way the convenience and veracity of the nondestructive detection have been promoted.
