Smart Reader

We would like to introduces the newly developed Data Matrix code reading software. Combined with an intelligent camera, the VC Smart Reader enables quick and reliable identification of 2D codes. The VC Smart Reader software has been optimized for use with VCOptimum, VCProfessional, VC Board Cam and VisiCube camera types.

The special features of the VC Smart Reader Software:

•  360 degrees rotation
•  Fast algorithm detects and reads codes with up to 150 fps
•  The module size can be as small as 2x2 pixel
•  Code detection and reading is not affected by the code shape and size
•  The orientation of the code or by the background type (dark-on-bright or bright-on-dark)
•  Mirrored codes are reliably identified and read
•  Just as special code types, such as nailed or dotted codes
•  Reading is not influenced by a covered "L" corner or a partially destroyed "L" pattern of the Data Matrix code.

Features of VC Smart Reader

Applications areas for VC Smart Reader 

VC Smart Reader Demo Version 

It features three operation modes:

•  The "Auto Mode" requires no configuration efforts
•  The "Teach-In Mode" allows users to read in one code sample whose parameters are stored in a list, and
•  The "Parameter Adjustment Mode" allows for manual adjustment of parameters to improve performance

What is a Data Matrix Code?

•  Two-dimensional  matrix code
•  The size can be modified dynamically
•  Code sizes from 1x1 up to 100x100mm²
  
•  The form: quadrate, rectangular, multiple codes

OCRLib

The VC Optical Character Recognition (OCR) Library

Description
In many domains of monitoring, inspection and control, reading a sequence of characters for verification or recognitionis an essential part of a final examination.Most often this problem can be reduced to the recognition of a smallsubset of a font especially constructed for the discrimination task. The VCOCR package contains all the functions for the teaching and verification of printed or otherwise uniformly produced characters.

Features and advantages:

•  nearly arbitrary fonts (can be recognised)
•  recognition can be done scale and rotation invariant
•  detection and recognition of not connected characters (umlaut, tilde, ... )
•  calculation of best, second and third best match (output of quality value)
•  fast recognition (less than 20 msec on a VC4038/E at character size 20x32)
•  easy adding further characters with re-teach tool
•  all operations can be performed on the camera
•  easy to use
•  only few (3) essential parameters

OpenCV

  The open source image processing library Open CV now running on all VC Smart Cameras

Image processing expert Vision Components has adapted the open source program library OpenCV to its proprietary VCRT operating system, im-plementing it on all VC Smart Cameras. OpenCV was originally developed by Intel® and published under a BSD license, running only on Windows, Mac OS X and Linux systems. Integrating it into Smart Cameras has increased their application range, since OpenCV includes many algorithms enabling, for instance, movement detection, facial recognition, object tracking, contour processing and image segmentation.


The fast image processing library complements VC Smart Cameras, which in-dependently execute all image processing routines thanks to their integrated intelligence, thus replacing standard PC-based systems. The compact cameras are suitable for industrial environments and incorporate all components required for image processing: image sensor, processor, frame grabber, interfaces and several PLC I/Os.
