The PC Eyebot works in color or monochrome, with patterns and textures, ignores clutter and confusing backgrounds, and accommodates variable lighting and reflections. It requires limited or no product fixturing and frequently needs no triggers or strobe lights for high-speed production lines.
This new inspection device can function in most places human inspectors work. "It's effective on production lines from fluids to pharmaceuticals, from hardware devices to food processing," says Tom Seitzler, marketing manager at Sightech Vision Systems Inc. "If a human inspector can inspect it, generally, so can the PC Eyebot, but faster and more effectively."
A user interface provides enhanced and optimized versions of the software tools found in previous-generation inspection processors. These are fully integrated and operational out of the box. The drop-down menu under each title contains numerous algorithms, which may be selected to enhance the feature definition. The effect of the algorithm is immediately viewable on the camera data, allowing the operator to decide if it improves the feature definition.
When the operator has adequate feature definition, he must then ensure that the processing mode selected will provide desired results: pass/fail or absent/present. Like the feature definition modes, the feature processing modes are generally provided for the specific application.
To interface with the production line equipment, the system sends a 12-volt rejection signal to the output connector on the back of the system's box when bad products are encountered. It also provides a programmable delay to accommodate production line and ejector characteristics. Good, marginal and bad enunciation signals are settable outputs. The operator's PLC may need adjustments to ensure reaction by the operator's system on a timely basis to the PC Eyebot's output signals.
Given the correct selections and a working environment, operators may experiment with the settings and fine-tune their performance as lighting, processing speeds and product changes occur. No software has to be generated or developed to have a functioning inspection system. Operators select the options and view the result.
This new system can perform numerous applications previously unfeasible with older generation equipment such as frame grabbers, video processors, smart cameras and software libraries. With no programming, it can recognize patterns and textures in biological filters; overcome or even make use of reflections in packaging; see slag or poor casting residue in injection molding products and work in variable lighting in liquid flow. It's doing all of this with just the hardware and internal software, no software development, often no triggers or strobes, and generally within a few minutes of the presentation of the problem to the PC operator.
