I'm attempting to use Tesseract-OCR-iOS in a new Swift 3.0 project. I'm using Xcode Version 8.1 (8B62). CocoaPods is version 1.1.1.
When I attempt to use tesseract.recognize(), my app crashes and I get the following output in the console:
actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES:Error:Assert failed:in file tessdatamanager.cpp, line 53 I found this post, which sounds I'm using the wrong version of traineddata. I downloaded tessdata from the tesseract-ocr/tessdata repo, so I'm baffled as to why I'd have a mismatch on the version numbers.
Any suggestions how to get Tesseract working are greatly appreciated. Below is additional information re: my setup.
Here's what my Podfile looks like:
# Uncomment the next line to define a global platform for your project platform :ios, '9.0' target 'TesseractDemo' do # Comment the next line if you're not using Swift and don't want to use dynamic frameworks use_frameworks! # Pods for TesseractDemo pod 'TesseractOCRiOS', '4.0.0' end I've dragged a tessdata folder containing eng.traineddata into the root directory of my project outside of Xcode and dragged a reference from Finder to Xcode's Project Navigator.
Everything works fine up to this point. No compiler errors, linker whining, etc. In a UIViewController I'm importing TesseratOCR and calling it like so:
// MARK: - OCR Methods func scanImage(image: UIImage) { if let tesseract = G8Tesseract(language: "eng") { tesseract.delegate = self tesseract.image = imageToScan?.g8_blackAndWhite() tesseract.recognize() textView.text = tesseract.recognizedText } } Update I found a link to a repo of traineddata files for version 4.0. I nuked my old eng.traineddata file and replaced it with the one from the 4.0 repo. I get the same error referencing the same line.
