Introduction
The Scanbot SDK comes with separate scanners for many specific use cases. Use cases that are not covered by any of these specialized scanners can be tackled with the Text Pattern Scanner Module.
The Text Pattern Scanner uses OCR to scan text within a user-defined rectangular area of interest, in consecutive video frames. A customizable block lets you clean up the raw string by filtering it against unwanted characters and OCR noise. Additionally, you can validate the result using pattern-matching or another block.
Use cases for the Text Pattern Scanner Module include scanning single-line text like IBAN numbers, insurance numbers, dates and other textual data fields that can be easily validated, i.e. pattern-matched.
The Text Pattern Scanner is more reliable and robust than using OCR by itself, since it accumulates the results of multiple video frames as well as your input from the raw text clean-up block.
