A dynamic framework for intelligent inspection

technical reportCAD (Computer Aided Design) typically involves the design, manufacture and inspection of a mechanical part. The problem of reverse engineering is to take an existing mechanical part as the point of departure and to inspect or produce a design, and perhaps a manufacturing process, for the part. We propose to explore the feasibility of a new approach to inspection and reverse engineering applications. In particular, we investigate t h e use of discrete event dynamic systems (DEDS) to guide and control the active exploration and sensing of mechanical parts for industrial inspection.

Intermediate results in active inspection and reverse engineering

technical reportIn previous work [18], we have proposed a new design for inspection and reverse engineering environments. We have investigated the use of the dynamic recursive context of discrete event dynamic systems (DRFSM DEDS) to guide and control the active exploration and sensing of mechanical parts for industrial inspection and reverse engineering, and utilized the recursive nature of the parts under consideration. In our recent work, we construct a sensing to CAD interface for the automatic reconstruction of parts from visual data. This report includes previous results and describes this interface in greater detail, demonstrating its effectiveness with a reverse-engineered, machined part

Photogrammetry for 3D Reconstruction in SOLIDWORKS and its Applications in Industry

Indiana University-Purdue University Indianapolis (IUPUI)Close range, image based photogrammetry and LIDAR laser scanning technique are commonly utilized methodologies to snap real objects.3D models of already existing model or parts can be reconstructed by laser scanning and photogrammetry. These 3D models can be useful in applications like quality inspection, reverse engineering. With these techniques, they have their merits and limitations. Though laser scanners have higher accuracy, they require higher initial investment. Close-range photogrammetry is known for its simplicity, versatility and e ective detection of complex surfaces and 3D measurement of parts. But photogrammetry techniques can be initiated with comparatively much lower initial cost with acceptable accuracy. Currently, many industries are using photogrammetry for reverse engineering, quality inspection purposes. But, for photogrammetric object reconstruction, they are using di erent softwares. Industrial researchers are using commercial/open source codes for reconstruction and another stand-alone software for reverse engineering and mesh deviation analysis. So the problem statement here for this thesis is to integrate Photogrammetry, reverse engineering and deviation analysis to make one state-of-the-art work ow. xx The objectives of this thesis are as follows: 1. Comparative study between available source codes and identify suitable and stable code for integration; understand the photogrammetry methodology of that particular code. 2. To create a taskpane add-in using API for Integration of selected photogrammetry methodology and facilitate methodology with parameters. 3. To demonstrate the photogrammetric work ow followed by a reverse engineering case studies to showcase the potential of integration. 4. Parametric study for number of images vs accuracy 5. Comparison of Scan results, photogrammetry results with actual CAD dat

A new method of measuring the 3-D shape and surface reflectance of an object using a laser rangefinder

The present paper describes a newly proposed method for simultaneously measuring 3D shape and surface reflectance of an object using a laser rangefinder. The original work of this method lies in the advantage that the proposed method measures the surface reflectance using the object itself that is used for the 3D shape measurement. Experimental results show that the proposed method was applicable to noncontact industrial inspection, robot vision in automatic assembly, and reverse engineering.</p
