# License Plate Recognition-Android

`KBY-AI`'s `LPR` on-premise Android `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`.

`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.

## About SDK

#### 1. Set up

**1.1 Setting Up ALPR SDK**

> Android

* Copy the SDK(folder `libttvalpr`) to `root` folder in your `Android` project.
* Add SDK to the project in `settings.gradle`.

```gradle
include ':libttvalpr'
```

**1.2 Add dependency to your `build.gradle`**

```dart
implementation project(path: ':libttvalpr')
```

#### 2 API Usages

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

```kotlin
var ret = AlprSdk.setActivation("xxx...")
```

* Extract plates using the `extractFaces` method:

```kotlin
 val alprResult: AlprResult = AlprSdk.process(
      SDK_IMAGE_TYPE.ULTALPR_SDK_IMAGE_TYPE_RGBA32,
      nativeBuffer, width.toLong(), height.toLong()
 )
 val plates = AlprUtils.extractPlates(alprResult);
```
