摘要： A computer implemented method for aligning objects receives a reference object and a to-be-moved object; determining feature elements of the reference object. A first coordinate system is constructed according to a plurality of feature elements of the reference object. A second coordinate system is constructed according to a plurality of feature elements of the to-be-moved object. A third coordinate system is constructed according to the first coordinate system and the second coordinate system. An operation matrix is computed according to the three coordinate systems. The two objects are aligned using the operation matrix.

摘要： A detecting method for measuring gaps between two parts of an object is provided. The detecting method selects a reference image and a measured image, merges the reference image and the measured image to form an image of the object, grids the reference image and the measured image to obtain triangle mesh surfaces, obtains boundary points and outline points of the measured image, and obtains triangles on a joint portion of the reference image and measured points on a corresponding joint portion of the measured image. The method further compares each measured point with an obtained triangle to obtain gap values of the joint portion between the reference image and the measured image, and outputs an analysis report of the gap values on a display device.

摘要： A system and method for converting a conventional surface into a non-uniform rational basis spline (NURBS) surface generates a constructed curve according to a first NURBS curve of the conventional surface which is read from a storage system. The system and method further converts the constructed curve into the second NURBS curve. Furthermore, the system and method constructs the NURBS surface based on the first NURBS curve and the second NURBS curve.
