Surface defect imaging challenge at PPMA Show
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; high-speed inspection and visitors are invited to bring their own samples to see high-resolution surface defect detection in action.
Stemmer Imaging'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.
Stemmer Imaging will be on Stand A44 at the PPMA Show, which takes place at the UK's NEC from 29 September to 1 October 2015. For more information about the company's range of vision technology products please visit www.stemmer-imaging.co.uk.
