VNRecognizeTextRequest无法识别Dansk语言“ da-DK”

问题描述

VNRecognizeTextRequest无法识别Dansk语言的特殊字符，例如Æ，æ，Ø，ø，Å，å，ß

将这些单词替换为Æ到AE，Ø到0，O，Å到A等。

下面是我的OCR实现代码。

private func configureOCR() {
    
    ocrRequest.recognitionLevel = .accurate
  
    ocrRequest.recognitionLanguages = ["da-DK","nl-NL","de-DE","en-US","en-AU"]
    ocrRequest.usesLanguageCorrection = true
    
    ocrRequest = VNRecognizeTextRequest { (request,error) in
        guard let observations = request.results as? [VNRecognizedTextObservation] else { return }
        
        var ocrText = ""
        for observation in observations {
            guard let topCandidate = observation.topCandidates(1).first else { return }
            
            ocrText += topCandidate.string + "\n"
        }
        
        
        DispatchQueue.main.async {
            self.ocrTextView.text = ocrText
            self.scanButton.isEnabled = true
        }
    }
    
}

视觉或视觉套件是否支持Dansk语言？

解决方法

我不这么认为。如果您查看文档

library(dplyr)
library(rlang)

func <- function(data1,data2,data1col,data2col,newcol) {
  data2 %>% 
       mutate(!!newcol := factor(as.integer(.data[[data2col]] %in% 
                                  data1[[data1col]])))
}
