Inline Optical Inspection Library Handles Large Point Clouds

There is a growing trend for using optical geometrical inspection systems completely integrated inside manufacturing machines and processes thereby allowing the early detection of product deviations and their correction.

OptoInspect3D developed, by The Fraunhofer Institute, allows rapid and automated processing of the large 3D data sets generated by optical inspection systems and compares them with nominal reference geometry allowing validation of each manufactured part inline.

OptoInspect3D functions are provided as a library allowing their flexible integration into standard or customized optical inspection systems and offers the following features:

High Performance
Highly efficient algorithms and data structures, combined with multi-core support, allows huge data sets to be processed fast enabling real time evaluations.
Simple and Flexible Integration
Independent of the digitization method or optical scanning device 3D point clouds can be analysed and their geometry validated. The C++ function libraries can be easily accessed via a C API and integrated into customized applications and workflows. A graphical environment is available to test the different functionalities and definition of geometric parameters of the point clouds analysis.
Certified Accuracy
German National Metrology Institute (PTB) certified with “deviations of the smallest order” (< 0.1 μm or 0.1“)
Robust and Efficient Methodologies
• Alignment (Registration)
• Comparison nominal/actual (CAD, point cloud)
• Approximation via geometric primitives (3D, 2D)
• Filtering, Smoothing, Elimination of outliers
• Segmentation
• Geometric Dimensioning and Tolerancing analysis (GD&T)

OptoInspect3D Inline is available with number of available licensing options for OEM’s and system integrators.

As a recent example the OptoInspect3D Inline library, Fraunhofer IFF and an industrial partner developed an automated optical 3D measurement system for the geometrical inspection of automotive wheels which allowed geometric 100% fully automated wheel quality checks to be integrated into the manufacturing process.
