... and inspection data into an AR scene. As a result, product manufacturing information with three-dimensional (3D) model data and corresponding inspection results are successfully overlaid onto a physical part. We demonstrate our pipeline by interacting with annotated parts while continuously tracking their pose...

...Kristina Wärmefjord; Johan S. Carlson; Rikard Söderberg In the auto body assembly process, fixtures position parts during assembly and inspection. Variation in the positioning process propagates to the final assembly. To control the assembly fixtures, repeatability studies are used. Those studies...

...; Sqrt[t1*t2*t3*t4]/4 CMM Computational geometry CMM GD& Tolerance modeling Inspection In the world of geometric dimensioning and tolerancing (GD&T), datums are used extensively to locate and orient tolerance zones [ 1 – 7 ]. Datum planes in particular are common...

...Ahmad Barari; Hoda A. ElMaraghy; George K. Knopf Integrating computational tasks in coordinate metrology and its effect on the inspection’s uncertainty is studied. It is shown that implementation of an integrated inspection system is crucial to reduce the uncertainty in minimum deviation zone (MDZ...

...A. Miropolsky; A. Fischer Inspection of machined objects is one of the most important quality control tasks in the manufacturing industry. Ideally, inspection processes should be able to work directly on scan point data. Scan data, however, are typically very large scale (i.e., many points...

...Giovanni Moroni; Marco Rasella When dealing with inspection or reverse modeling, the problem of free-form curves and surfaces reconstruction has to be faced starting from a set of measured points. Because in point sampling the acquisition error is unavoidable, curves and surfaces fitting should...

...) and engineering analysis. We begin with a summary of the relative strengths and weaknesses of individual NDT modalities. Thereafter we present existing multimodal inspection hardware systems that use complementary NDT sensors. The advantages of such multimodal data acquisition over conventional single modality...

... frame from that of the existing objects in the virtual world. To rectify these differences, a process called registration is often applied. This paper uses a case study to highlight the differences between various registration techniques. 11 09 2005 27 07 2006 CAD/CAM inspection...

...D. Steiner; R. Katz Continuous improvement of product quality is essential to the success of manufacturing enterprises. In-process inspection plays an important role in improving product quality control of mass produced products. The change that has occurred in traditional mass production, i.e...

... supports a broad variety of measuring devices via one user interface. Based on Windows Operating System (OS) a software was developed able to control inspection devices for different types of geometry measurements (coordinate measuring machine, form, roughness, gear) and manufacturers by one defined...

..., derivative computations are unstable for real data, and the estimated curvature is thus very sensitive to noise. Moreover, in many cases, spatial fitting of corresponding points is not sufficient. The current work utilizes the curvature properties to inspect manufactured parts that have been reconstructed...
