mrz_scanner library
Reads the machine readable zone of passports, identity cards and visas in a camera frame or a photo, in pure Dart: the key that opens their chip, without typing it.
An MrzRecognizer reads one image; an MrzScanner reads the frames of a camera until enough of them agree.
import 'package:eid_icao/mrz_scanner.dart';
final scanner = MrzScanner();
final result = scanner.add(MrzImage.luminance(
width: frame.width,
height: frame.height,
bytes: frame.bytes,
));
if (result != null) await IcaoReader(transport).read(access: result.accessKey);
Classes
- MrzImage
- A grey image: a camera frame, a photo of a document, a crop of either.
- MrzReading
- A zone read from one image: the text, how sure the reading is, where the zone lies.
- MrzRecognizer
- Reads the machine readable zone of a passport, an identity card or a visa in an image, without any other library: OCR-B glyphs matched against the cells of the zone, check digits putting near ties right.
- MrzScanner
- Reads the zone in the frames of a camera until enough of them agree.
- MrzScanResult
- A zone read and confirmed by several frames: ready to open the chip.
Enums
- MrzRotation
- How far a frame is turned from upright: the quarter turns, clockwise, that bring its text level.
