Imagechecker P400MA and P400
Inspection functions
Object identification and position detection made easy
Inspection and verification of characters, codes and prints
OCR/OCV
A powerful tool to read and verify
characters, strings and symbols. We
have expanded the functionality of this
checker. Now, also rotated or even
curved strings can be read.
P400 systems offer various tools to check the quality and completeness of complete prints, to read strings of characters (Optical
Character Recognition), to verify strings (Optical Character Verification) or to read a variety of different codes. The employed
techniques guarantee high reliability and precision even under severe inspection conditions.
Vision P400 includes several algorithms which allow fast, reproducible and
precise recognition, identification and location of objects. Our powerful
Contour-Matching Checker is an especially impressive tool for such
inspection tasks. It evaluates objects based on previously trained models,
judging geometric information instead of pixel patterns, thereby achieving
revolutionary stability and detection speed. Furthermore this algorithm can
handle all those disruptive factors, which often disqualify conventional
inspection methods for the real factory environment: fluctuating illumination,
changing object appearance, touching and overlapping objects.

Print inspection
Typically blurred or incomplete imprints
have to be detected. P400 is able to
localize quality deviations which can
barely be seen by the human eye.
2D code reading
This newly developed Checker reads D
codes such as Datamatrix, ECC00 and
QR code. Regardless of whether the
codes are randomly twisted or serious
changes in brightness occur, this
powerful checker will read them reliably.
Setting the checker is as easy as
drawing a rectangle.
Barcode
Almost any barcode can be read with
this tool. /5 Industrial, Code 39/93/18,
EAN 13, EAN 8, UPC-A/E, and
Pr Pharma Code are just a few
examples.
