OCR
Introduction
OCR (Optical Character Recognition) application allows you to convert a printed text to a
digital text document and to vocalize its contents. The application uses the rear camera of
the SmartVision2, two-LED lighting system and a proximity sensor.
To scan a printed text, OCR application proceeds as follows:
·
Step 1: Take a picture
·
Step 2: Convert the picture to a text document in the desired language using the
OCR engine
·
Step 3: Vocalize the contents of the text document using the text-to-speech engine
A good image quality is essential for a successful recognition process. To take a superior
quality picture, SmartVision2 integrates a special lighting system as well as a proximity
sensor in combination with specific algorithms.

Take a picture
In order to improve the OCR result, your document must be placed in front of you, vertically
on a flat, clear, well-lit surface with a solid color contrasting to the document to be detected.
Place the document in front of you and point your smartVision2 camera about twenty
centimeters from the target. The OCR regularly announces the visible edges and the angle
of the sheet.
Reposition your phone to have the four corners of the sheet visible. Once the sheet is
correctly framed, the SmartVision2 tells you not to move and the picture is taken
automatically after a few seconds. Optical recognition starts when the picture is taken.
You can also force the capture of your document without having the four edges visible by
pressing the "OK" key.
Reading the OCR result
After the process is completed, the OCR result is automatically displayed and vocalized. If
the recognition does not work, we advise you to return to the main page of the OCR
