Setup Accura OCR
To initialize sdk on app start:
import AccuraOCR
var accuraCameraWrapper: AccuraCameraWrapper? = nil
var arrCountryList = NSMutableArray()
accuraCameraWrapper = AccuraCameraWrapper.init()
let sdkModel = accuraCameraWrapper.loadEngine(your PathForDirectories)
if (sdkModel.i > 0) {
// if sdkModel.isOCREnable then get card data
if (sdkModel.isOCREnable) let countryListStr = self.videoCameraWrapper?.getOCRList();
if (countryListStr != null) {
for i in countryListStr!{
self.arrCountryList.add(i)
}
}
}
}
arrCountryList to get value(forKey: "card_name") //get card Name
arrCountryList to get value(forKey: "country_id") //get country id
arrCountryList to get value(forKey: "card_id") //get card idOptional: Load License File Dynamically
If you prefer to place the license file dynamically, you can use the following function. This method allows you to specify the license file path at runtime
let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
let sdkModel = accuraCameraWrapper?.loadEngine("Your License Path", documentDirectory: documentDirectory)Note:- For a demo of dynamic licensing, please refer to the branch "dynamic_license_demo".
Update filters config like below.
Call this function after initialize sdk if license is valid(sdkModel.i > 0)
Set Blur Percentage to allow blur on document
// 0 for clean document and 100 for Blurry document
self.accuraCameraWrapper?.setBlurPercentage(60/*blurPercentage*/)Set Blur Face Percentage to allow blur on detected Face
// 0 for clean face and 100 for Blurry face
accuraCameraWrapper?.setFaceBlurPercentage(80/*faceBlurPercentage*/)Set Glare Percentage to detect Glare on document
// Set min and max percentage for glare
accuraCameraWrapper?.setGlarePercentage(6/*minPercentage*/, 98/*maxPercentage*/)Set Photo Copy to allow photocopy document or not
// Set allow photocopy document or not
accuraCameraWrapper?.setCheckPhotoCopy(false/*isCheckPhotoCopy*/)Set Hologram detection to verify the hologram on the face
// true to check hologram on face
accuraCameraWrapper?.setHologramDetection(true/*isDetectHologram*/)Set Low Light Tolerance to allow lighting to detect documant
// 0 for full dark document and 100 for full bright document
accuraCameraWrapper?.setLowLightTolerance(10/*lowlighttolerance*/)Set motion threshold to detect motion on camera document
// 1 - allows 1% motion on document and
// 100 - it can not detect motion and allow document to scan.
