Dome light units offer excellent results in a variety of machine vision tasks. However, due to their design they have not been suitable in applications where space is at a premium. With the launch of the LFX3 series, CCS has responded to these demands by combining the qualities of dome lights with a new flat design.
Inspection is a critical component of HACCP programs in the food industry. Hyperspectral imaging now provides a powerful complementary approach for the machine vision engineer. Its ability to identify differences in the chemical composition of organic materials opens up major new possibilities for detecting impurities in food products. Most importantly, systems are now available that operate in real time, allowing them to be used on high speed production lines.
The new CVS trevistaCAM is the latest addition to the CVS trevista range of advanced industrial surface inspection systems that use the patented 2.5D ‘shape from shading’ process. The low cost CVS trevistaCAM is a ready to use, completely self-contained 4 Mpixel smart camera system which has applications in automotive, print & packaging, test and measurement and the pharmaceutical Industry.
Witten-based OCS GmbH is one of the world’s leading manufacturers of production-integrated film inspection systems. Up to ten cameras operate side by side in scalable systems enabling production speeds of up to 1,200 metres per minute. Machine vision components from STEMMER IMAGING make up the optical solution.
Scanware Electronic inspects tablets in blister packs after sealing with the aid of powerful machine vision systems. One of these, the Lynx Spectra HR, developed in close cooperation with STEMMER IMAGING and utilising up to six watercooled 3CCD colour cameras from JAI, is an ideal system structure for use in a tight space.
Industrial vision plays an important role in reading unique identifiers in the form of 1D or 2D codes, alphanumerics or even braille for tracking and tracing applications in industries as diverse as aerospace, automotive, healthcare and pharmaceutical. Specialist vision systems integrators are frequently used to design systems for complex code reading tasks requiring extremely precise triggering and encoding to the manufacturing process. The choice of image processing software is important in complex imaging environments.
Codes may be printed or etched directly onto components or attached on labels. The vision system should have a camera and lens with sufficient resolution to read the particular code, an illumination system that allows the image to be produced with the necessary contrast, appropriate image processing software and a processor capable of running the software. The codes may need to be read at very high speed and at a number of different locations and the code reading process may be one vision task as part of a number of vision inspections in an overall quality inspection procedure.
Sherlock is an advanced machine vision software interface from Teledyne DALSA featuring a comprehensive suite of proven tools and capabilities that includes advanced pattern finding tools for object alignment and tools to read and verify 1D and 2D codes, as well as printed, moulded or stamped text (OCR). While these are essential requirements, it is Sherlock’s versatility that has such appeal for vision systems integrators. It allows mixing of imager type, resolution and interface in the same application and supports synchronous and asynchronous triggering.
Sherlock is ideally suited for use with multicore processors, offering the flexibility needed for different inspection speeds and machine cycle times. It is possible to set the software to use a single core, or all cores, allowing intensive processing inspections to use one or more cores with less intensive inspections using one core. In addition, Sherlock can be almost infinitely configured to run multiple cameras into one investigation or multiple investigations with single or multiple cameras.
Sherlock is also compatible with Visual Studio allowing the creation of custom user interfaces. Used in conjunction with Teledyne DALSA’s Sapera Vision Software libraries and drivers from STEMMER IMAGING’s CVB imaging toolkit, Sherlock can accept images from almost any camera, including line scan, area scan and 3D across all common interface formats such as GigE Vision, CameraLink and USB as well as emerging new image acquisition standards.
A contact lens manufacturer needed to read 1D, 2D and human readable codes on a packaging production line. This application was particularly challenging due to the number of part variances, and the incredibly tight physical constraints for the cameras and illumination.
Vision systems integrator, SIGA Vision, worked closely with vision technology supplier, STEMMER IMAGING, to develop a system that featured five asynchronous cameras using a single vision processor with multiple Sherlocks running. Demanding and complex projects such as these benefit from the joint expertise and breadth of technology offered by such a partnership.
SIGA Vision’s extensive experience in developing innovative machine vision software solutions, especially using Sherlock was complemented by STEMMER IMAGING’s wide-ranging choice of cameras, optics and lighting hardware from various manufacturers and comprehensive technical back-up for Sherlock.
