Characters Are Extracted One by One for Recognition.
With the OCR function, character recognition can be accomplished by
just registering characters and specifying the area.
Both alphanumeric characters and user-defined characters can be
identified.
The Auto calendar setting allows inspection of the date or lot
numbers without the need for daily setting change.
Functions equivalent to those of dedicated OCR machines are available, including offset, tolerance, and zero-suppress settings.
You can select whether to specify the detection areas automatically
or whether to fix the areas.
It is also possible to specify the ratio for the detection area.
The correlation percentage of successful character recognition is output for each character. Users can check characters for unstable recognition.
In addition to alphanumeric characters, up to 20 user-defined characters (kanji, symbol, etc.) can be registered.
In addition to filters such as expansion, shrink, and Sobel,
color binary conversion and color shade-scale processing can be
handled as a preprocessing operation. A total of 16 filters can be
specified for each window.
An image can be created by assigning optimum contrast to each area.
This function is useful to change the contrast according to
inspection items, or to process images with non-uniform light
distribution.
A captured image is analysed in real time, and only subtle
differences in the image can be extracted.
The extraction featore, which ignores the background, is effective
for the inspection of foreign matters and flaws.
