License Plate Recognition-Flutter

KBY-AI's LPR solutions utilize artificial intelligence and machine learning to greatly surpass legacy solutions. Now, in real-time, users can receive a vehicle's license plate number.

Automatic license-plate recognition (ALPR) is a technology that uses OCR(optical character recognition) on images to read vehicle registration plates. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ALPR can be used by police forces around the world for law enforcement purposes, including to check if a vehicle is registered or licensed. It is also used for electronic toll collection on pay-per-use roads and as a method of cataloguing the movements of traffic, for example by highways agencies.

Features

• Vehicle License Plate Reader

• OCR Based License Number Parser

• Vehicle Detection & Tracking

• Export License Plate Coordinate

• Support Car, Truck, Bus, etc

• Support Various License Plates From 180+ Counrtries

2. Running the App

Try to build this repo to make sure that SDK works fine by linking real Android phone, not simulator. Once it works fine, you are ready to integrate our SDK to your project. Run the following commands:

flutter clean
flutter pub get
flutter run

If you plan to run the iOS app, please refer to the following link for detailed instructions.

About SDK

1. Set up

1.1 Setting Up ALPR SDK

Android

• Copy the SDK(folder libttvalpr) to the folder android in your project.

• Add SDK to the project in settings.gradle.

include ':libttvalpr'

1.2 Setting Up ALPR SDK Plugin

• Copy the folder alprsdk_plugin to the root folder of your project.

• Add the dependency in your pubspec.yaml file.

  alprsdk_plugin:
    path: ./alprsdk_plugin

• Import the alprsdk_plugin package.

  import 'package:alprsdk_plugin/alprsdk_plugin.dart';

2 API Usages

2.1 ALPRsdk Plugin

• Activate the AlprsdkPlugin by calling the setActivation method:

  final _alprsdkPlugin = AlprsdkPlugin();
  ...
   await _alprsdkPlugin
          .setActivation(
              "o3AfDW+0LAb55qW354xp9ef/Twg1WumIcKaBQLydx+o7+8nuZSo4aL4vVGro3mNCLvo8C2OPNDjZ"
              "/8k+bvgbf8+QszGqG5ubjZOaREXO0Iw8pSepERy4HrWrS6I9ObjuttMUIRHBFNjIsT3RKH57mNv6"
              "1IXxewXlIA2oe5Vak/zaddoKKKcSW+iWJWqIa1MxGn8PpUD1riQS9RrO/cwZsiAJU+5+ekkkyP3C"
              "7eNZGzFfpmkLM55p2F98IMqWHjaMmX0klsNlxE/bdSJD8c2cS/+9DGLqiWb2FHz8FpR6sXjc+eGM"
              "bNtBd0YxqfAy+oeTVdPyw0E17lj+Hilw4L4C6Q==")
          .then((value) => facepluginState = value ?? -1);

• Initialize the AlprsdkPlugin:

await _alprsdkPlugin
          .init()
          .then((value) => alprpluginState = value ?? -1)

• Extract plates using the extractFaces method:

final plates = await _alprsdkPlugin.extractFaces(path: image.path)
