Automated mesh transfer and inspection in PC-DMIS using structured light

Supporting systems from coordinate measuring machines (CMMs) to portable measuring arms, structured light scanners and laser trackers, PC-DMIS is a measurement software solution for metrology professionals and shop-floor operators alike.

Featuring highly sophisticated measurement algorithms, PC-DMIS is the smart choice with industry-leading expertise and technical capability built-in. The powerful yet flexible PC-DMIS metrology software works with both Hexagon and third-party measurement systems, giving you a unified user experience across all your measurement operations, decreasing training costs and allowing better resource management. Plus, its modular design enables you to scale your installation as your metrology needs grow.

For metrology specialists creating measurement routines, PC-DMIS offers a complete suite of programming capabilities. The software provides a comprehensive geometric dimensioning and tolerancing (GD&T) toolset, complying to the latest industry standards. Offline programming functionality allows routines to be created without occupying the structured light system, and even before the physical part has been manufactured.

Combining the structured light scanning software with the inspection routine, PC-DMIS offers a powerful tool to automatically execute the inspection program once the scan is complete to automate the inspection process and generate a measurement report in seconds.

Example of a complete inspection program in PC-DMIS

The structured light software OptoCat is used for data processing. The software merges the scan data, aligns them, evaluates overlapping data derived from the multiple scans and deletes duplicated data based on quality criteria. This process results in a single mesh. The software OptoCat allows for fast but accurate post-processing that includes reduction and compression, filling of holes, and texture mapping. All data can be saved as STL, PLY, OBJ and other formats. The automated mesh transfer allows for direct import of scan data into PC-DMIS to start the inspection process without any user interaction.

The following video illustrates the complete workflow of passing data from OptoCat to PC-DMIS and executing the inspection routine automatically. The advantage for the user is that once an inspection program is created the scan is the only portion of the inspection process which can also be automated using an automated rotary table in combination with the structured light scanning system.
