Barcode software handles lower light levels

A move toward gradient pixel base threshold in FrameWork 2.7 has enabled more intelligence in the software to compensate for low-light levels and for variances of light in specific applications.
A move toward gradient pixel base threshold in FrameWork 2.7 has enabled more intelligence in the software to compensate for low-light levels and for variances of light in specific applications.
This means the software can predict missing 2D code, or read code that is incomplete or damaged.
The FrameWork 2.7 reader is also trainable: it can learn to make the compensations required to read bad code from first reading good code.
With Framework 2.7, both the Intelligent Scanner XS and IS can read an expanded list of barcodes including all seven RSS codes, USS 128 Composite, UPC/EAN Composite, Planet Code, Micro PDF and PDF truncated.
Additional reader improvements also include barcode grading for Code 39, Code 93, Codabar, and Interleaved 2 of 5.
FrameWork 2.7 also incorporates enhancements in colour applications.
The software now has a dynamic link between colour sensors and inspection sensors, and greater control over merged colours.
Setup time for the reader is reduced significantly by using a system that is more "point and click".
This FrameWork update, and all DVT software, is available totally free of charge - no purchase is necessary.
Framework software is compatible with all Legend series machine vision systems and is backward compatible with older DVT systems as well.
Its highly enhanced reader capabilities spring from the advantage taken with the new Texas Instruments DSP processor, which is standard in the DVT 550 series of Legend SmartImage sensors.
"FrameWork 2.7 contains features that make it more intelligent and more robust than previous versions of vision software", commented Steve Gieseking, DVT's Director of Research and Development.
"The improved reader capabilities include the ability to successfully read significantly degraded or poorly marked codes that may be found on metal parts using pin stamping".
Mike Schreiber, DVT Director of Applied Engineering, said: "FrameWork 2.7, combined with our 550 sensor products, gives our customers a new level of machine vision power that will make a substantial difference in many applications.
It also positions us as a leader in speed due to the scalability of the TI processor".
