OCR stands for "Optical Character Recognition" and means the automatic text recognition using a respective algorithm on an image (originating from a live camera feed, for example).
UBIK® clients are capable of OCR for the sake of identifying objects ().
Preconditions
- On Android devices, the UBIK® SmartClient app providing the OCR scanner has to be installed (see release portal).
- For Android, UBIK® objects to be found by OCR tag have to be classified as such, using the Object with OCR Text Classification.
- For the Windows 8 client until version 2.4.3, the optical code classification must be used instead. In later versions, the same classification as for Android will be used.
- The object to be found has to be available on the device, since online search currently is not enabled for this feature.
 | The UBIK® SmartClient and its OCR scanner are still in an early development state. Don't expect the feature to be perfect yet! |
Usage
UBIK® Android
In the Demo app, the navigation drawer provides a "Scanning" element, which has a sub-item "OCR" (). When clicking it, an OCR scanner is started. When a tag was recognized successfully, the scanner closes automatically and the result is shown in a result list. If the scanner doesn't find anything, a click on the screen closes it (without showing results).
Also, there is a new configurable start screen button for OCR ().
