我已經按照教程來獲取Tesseract,特別是苔絲二和眼睛二安裝和我的Android應用程序的一部分。tess-two OCR沒有正確解碼
它運行,但從 baseApi.getUTF8Text();
返回的OCR文本是完整的亂碼。
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", "=======================================================================================");

三星Galaxy Tab 2 7" 沒有按在主攝像頭(後置)上沒有自動對焦功能,所以在使用不同設備之後,您不可能獲得更好的效果。 – rmtheis
