我已经按照教程来获取Tesseract，特别是苔丝二和眼睛二安装和我的Android应用程序的一部分。tess-two OCR没有正确解码

它运行，但从 baseApi.getUTF8Text();返回的OCR文本是完整的乱码。

BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inSampleSize = 4; 
     Bitmap bmp = BitmapFactory.decodeFile(path , options); 
     receipt.setImageBitmap(bmp); 
     try { 
      ExifInterface exif = new ExifInterface(path); 
      int exifOrientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION , ExifInterface.ORIENTATION_NORMAL); 
      int rotate = 0; 
      switch (exifOrientation) { 
       case ExifInterface.ORIENTATION_ROTATE_90: rotate = 90; break; 
       case ExifInterface.ORIENTATION_ROTATE_180: rotate = 180; break; 
       case ExifInterface.ORIENTATION_ROTATE_270: rotate = 270; break; 
      } 
      if (rotate != 0) { 
       int w = bmp.getWidth(); 
       int h = bmp.getHeight(); 
       Matrix matrix = new Matrix(); 
       matrix.preRotate(rotate); 
       bmp = Bitmap.createBitmap(bmp, 0, 0, w, h, matrix, false); 
      } 
      bmp = bmp.copy(Bitmap.Config.ARGB_8888, true); 
      TessBaseAPI baseApi = new TessBaseAPI(); 
      baseApi.init(DATA_PATH , "eng"); 
      baseApi.setImage(bmp); 
      String OCRText = baseApi.getUTF8Text(); 
      baseApi.end(); 
      Log.i("OCR Text", "rotate " + rotate); 
      Log.i("OCR Text", "OCR "); 
      Log.i("OCR Text", OCRText); 
      Log.i("OCR Text", "=======================================================================================");
