Barcodescanner

Dies ist eine Android-Barcode-Scanning-Bibliothek, die dazu entwickelt wurde, Barcode-Daten aus einem Live-Kamera-Feed zu erkennen und zu dekodieren. Sie bietet die Kerninfrastruktur für die Übersetzung visueller Muster in Text auf Mobilgeräten.

Die Bibliothek enthält einen Kamera-Preview-Manager, der Seitenverhältnisse und Feed-Größen an verschiedene Bildschirmdimensionen anpasst, sowie einen Hardware-Controller zur Verwaltung von Blitz, Autofokus und Sensorauswahl. Zudem verfügt sie über einen Barcode-Format-Filter, um das Scannen auf spezifische Barcode-Typen zu beschränken und so Erkennungsgeschwindigkeit und -genauigkeit zu erhöhen.

Das Projekt deckt Kamerahardware-Steuerung, Live-Barcode-Dekodierung und Anpassung der Benutzeroberfläche für den Entwurf maßgeschneiderter Sucher und visueller Overlays ab.

Features

  • Camera Feed Decoders - Detects and decodes barcode data from a live camera feed by translating visual patterns into text.
  • Android Camera Barcode SDKs - Provides a comprehensive SDK for integrating real-time barcode scanning into Android applications via the device camera.
  • Android Barcode Scanner Libraries - Provides an Android library for detecting and decoding barcode data from a live camera feed.
  • Camera Capture Controllers - Handles low-level camera hardware control, including flash and autofocus, to optimize scanning image quality.
  • Flash and Focus Controls - Provides programmatic management of flash toggling and autofocus to optimize image capture for scanning.
  • Advanced Mobile Camera Controls - Manages camera sensors, autofocus, and flash settings on Android devices to optimize scanning image capture.
  • Hardware Abstraction Layers - Provides a consistent API for managing camera flash, autofocus, and sensor selection across different Android devices.
  • Preview Aspect Managers - Adjusts the aspect ratio and size of camera feeds to fit various Android screen dimensions.
  • Custom Viewfinder Designs - Creates tailored view finders and visual overlays to guide users during the barcode scanning process.
  • Aspect Ratio Correction - Adjusts camera preview dimensions to prevent image stretching and maintain correct proportions across different screen scales.
  • Camera Index Selections - Enables switching between available camera sensors on the device to source the scanning feed.
  • Event-Driven Callbacks - Triggers specific application actions immediately after a barcode is successfully decoded from the camera feed.
  • Viewfinder Overlays - Renders a customizable visual guide over the camera preview to assist users in aligning barcodes.
  • Camera Preview Embeddings - Manages the embedding and aspect ratio of the camera preview within the Android view hierarchy.
  • Preview Dimension Scaling - Adjusts preview size and aspect ratio tolerance to ensure the camera view fits various screen dimensions.
  • Custom View Rendering - Allows modifying the appearance and shape of the scanning overlay using custom visual attributes.
  • Barcode Format Filters - Restricts decoding to a specific subset of barcode formats to increase detection speed and accuracy.

    This is an Android library that adds barcode scanning to applications using the device camera. It wraps the ZXing barcode decoding engine and exposes it through a simplified Android API, functioning as a software development kit for real-time scanning. The library offers two primary integration approaches: launching a full-screen camera activity through Android intents, or embedding a live scanner view directly into application layouts using SurfaceView or TextureView. Scanner behavior can be customized through programmatic configuration objects before scanning begins, and scanned barcode dat
