# License Plate Recognition-Flutter

`KBY-AI`'s `LPR` on-premise `Flutter SDK` utilizes artificial intelligence and machine learning to greatly surpass legacy solutions. Now, in real-time, users can receive a `vehicle's license plate number` on `Android` or `iOS` device.

`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

* [x] Vehicle License Plate Reader
* [x] OCR Based License Number Parser
* [x] Vehicle Detection & Tracking
* [x] Export License Plate Coordinate
* [x] Support Car, Truck, Bus, etc
* [x] Support Various License Plates From 180+ Counrtries
* [x] Support Android & iOS
* [x] On-Premise, Fully Offine Work

## License

We offer `lifetime license(perpetual license)` tied to each  `application ID`. 

The license is available with a `one-time payment`—meaning once you purchase it, you can use our `SDK` indefinitely without any recurring fees.

## How To Run

#### 1. Flutter Setup

Make sure you have `Flutter` installed.\
This repo has been built with Flutter version `3.22.3`.\
If you don't get `Flutter` installed, please follow the instructions provided in the official `Flutter` documentation [here](https://docs.flutter.dev/get-started/install).

#### 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:

```bash
flutter clean
flutter pub get
flutter run
```

If you plan to run the iOS app, please refer to the following [link](https://docs.flutter.dev/deployment/ios) 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`.

```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.

```yaml
  alprsdk_plugin:
    path: ./alprsdk_plugin
```

* Import the `alprsdk_plugin` package.

```dart
  import 'package:alprsdk_plugin/alprsdk_plugin.dart';
```

#### 2 API Usages

**2.1 ALPRsdk Plugin**

* Activate the `AlprsdkPlugin` by calling the `setActivation` method:

```dart
  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`:

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

* Extract plates using the `extractFaces` method:

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