OpenALPRSwift is an iOS Framework for the open source OpenALPR Automatic License Plate Recognition library http://www.openalpr.com. It can be used in Swift and Objective-C
The library analyzes images and video streams to identify license plates. The output is the text representation of any license plate characters.
Current version is using precompiled Frameworks from cardash:
- leptonica.framework
- tesseract.framework
openalpr.framework compiled from v2.3.0 and dependency pod v3.1.0.1 for OpenCV
- iOS 9+
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapodsCocoaPods 1.3.0.beta.2+ is required to build OpenALPRSwift 1.0.0+.
To integrate OpenALPRSwift into your Xcode project using CocoaPods, specify it in your Podfile:
platform :ios, '9.0'
use_frameworks!
target '<Your Target Name>' do
#pod 'OpenALPRSwift', '~> 1.0.0'
pod 'OpenALPRSwift', :git => 'https://github.com/yasirmturk/openalpr-swift.git', :tag => 'v1.0.0'
endThen, run the following command:
$ pod installIf you get an error complaining about "transitive dependencies" then put this in your Podfile
pre_install do |installer|
Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end
import OpenALPRSwift
in your class and then
let imagePath = Bundle.main.path(forResource: "dk_vb33742", ofType: "jpg")
let alprScanner = OAScanner(country: "eu", patternRegion: "dk")
alprScanner?.scanImage(atPath: imagePath, onSuccess: { (plates) in
plates?.forEach({ (plate) in
print("result: \(plate.number)")
})
}, onFailure: { (error) in
print("error: \(error?.localizedDescription)")
})
or you can pass a UIImage as well
Specifies which OpenALPR config file to load, corresponding to the country whose plates you wish to recognize. Currently supported values are: [au, auwide, br, eu, fr, gb, kr, kr2, mx, sg, us, vn2]
Specifies which plate pattern to look for e.g. dk for Denmark or al for Alabama. Complete list of patterns is available under runtime_data/postprocess/*.patterns
