A method and system for full-field fringe-projection for 3-D surface-geometry measurement, referred to as “triangular-pattern phase-shifting” is disclosed. A triangular grey-scale-level-coded fringe pattern is computer generated, projected along a first direction onto an object or scene surface and distorted according to the surface geometry. The 3-D coordinates of points on the surface are calculated by triangulation from distorted triangular fringe-pattern images acquired by a CCD camera along a second direction and a triangular-shape intensity-ratio distribution is obtained from calculation of the captured distorted triangular fringe-pattern images. Removal of the triangular shape of the intensity ratio over each pattern pitch generates a wrapped intensity-ratio distribution obtained by removing the discontinuity of the wrapped image with a modified unwrapping method. Intensity ratio-to-height conversion is used to reconstruct the 3-D surface coordinates of the object. Intensity-ratio error compensation involves estimating intensity-ratio error in a simulation of the measurement process with both real and ideal captured triangular-pattern images obtained from real and ideal gamma non-linearity functions. A look-up table relating the measure intensity-ratio to the corresponding intensity-ratio error is constructed and used for intensity-ratio error compensation. The inventive system is based on two-step phase-shifting but can be extended for multiple-step phase-shifting.

A method in which a network management system (NMS) processes information on a fault, such as numerous alarms or events, generated from high-capacity network equipment and forwards the processed fault information to a client in real-time. More particularly, the present invention relates to a fault information processing method and system for processing alarms more rapidly and efficiently using database table modeling to improve a delay in storing data in an alarm database in applications, which is most problematic in processing alarms and events. With the present invention, the temporary storage of the traps in the listener table is simply performed by the fault management module and other additional functions spending time are performed by adopting an asynchronous transaction processing manner through the listener daemon module in order to more rapidly and quickly process a large amount of alarm and event information which could not be satisfied in an existing synchronous manner, thereby realizing real-time processing of a number of traps.

The invention relates to a computer-based method and system to facilitate quality control for manufactured assemblies based on computer aided design (CAD) files. The instant invention mitigates the problems encountered with large CAD files by decomposing each of such files into a multi-file format. A large CAD file is thereby broken-down into smaller files that organize the information contained in the larger file. The organization is performed in such a way that the information pertinent to the measurement process is segregated into a different smaller file than the information not needed to calculate measurements. Thus, the computer running the computation accesses a smaller file containing a higher percentage of required information. Additionally, assisting the user in coordinating a match-up between the physical surfaces being measured and the proper associated CAD model version of that surface further increases the handling speed. In particular, the instant invention uses selection regions for each surface. A selection region consists of the representation of a three-dimensional rectangle region just large enough to enclose each individual surface. A selection region indexes each surface. Thus, when a measurement point is taken, a list of surface regions is automatically scanned in order to determine which region contains that point. The corresponding distance of that measurement point to the surface is then calculated.
