# License Plate Recognition-iOS

`KBY-AI`'s `LPR` iOS `SDK` utilized 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

* [x] Vehicle License Plate Reader
* [x] OCR Based License Number Parser
* [x] Vehicle Detection & Tracking

## License

We offer `lifetime license(perpetual license)` tied to each  `bundle ID` for `iOS` `SDK`s. 

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

## About SDK

#### 1. Set up

**1.1 Setting Up ALPR SDK**

> iOS

* Copy the `SDK` library (`alprsdk.framework` folder) and pre-built `onnxruntime` library (`onnxruntime.framework` folder) to the `root` folder in your project.
* Add `alprsdk.framework` and `onnxruntime.framework` to your project in `Xcode`.

> Project Navigator -> General -> Frameworks, Libraries, and Embedded Content

#### 2 API Usages

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

```swift
var ret = ALPRSDK.setActivation("xxx...")
```

* Get license plate number and its coordinates by calling the `processImage` method:

```swift
  let processImage = pickedImage.fixOrientation()
  let alprBoxes = ALPRSDK.processImage(processImage) as! [ALPRBox];
  let imageWithBoxes = drawALPRBoxes(on: processImage, boxes: alprBoxes)
```
