Surface defect imaging challenge

31 July 2015

A number of different demonstration systems will showcase Stemmer Imaging's extensive range of vision technology products and expertise at the PPMA Show. This will include many aspects of package inspection and high-speed inspection.

The company's novel Trevista Surface 50 inspection system is supplied complete with structured diffuse illumination, lens, software, PC and a 5 MPixel Genie TS camera from Teledyne DALSA. Using a patented "shape from shading" technology, information on the three-dimensional shape of an object can be deduced from the shading of its surfaces. This allows defects of just a few microns diameter and depth to be detected on a variety of material surfaces. Visitors to the show can bring their own samples along to put this to the test.

The package inspection demonstrator will illustrate a wide variety of inspection applications including OCR and print quality as well as 3D inspection using laser triangulation. It features cameras from a number of different suppliers, including Allied Vision, Teledyne DALSA and JAI. The cameras, with resolutions ranging from VGA to 5 Mpixels and operating at different frame rates to suit the particular inspection are located on a continuous conveyor system.

Also on show will be a high speed imaging system which will show image sequences produced from a miniature roller coaster system. The sequences are generated from high speed images acquired into the ring buffer of Common Vision Blox, Stemmer Imaging's own hardware-independent imaging toolkit. Stand A44
