Firebase OCR вывод неверный

0 голосов
/ 30 апреля 2019

Я использую Firebase OCR для получения текста с изображения.Я храню этот текст в elementList, каждое слово отдельно.Когда я вижу, что содержит elementList (см. Logcat), я получаю много странных строк, которые не имеют ничего общего с реальным текстом.

Java 

    private void readTextFromImage() {
        ArrayList<String> frequencyList = new ArrayList<>();
        elementList = new ArrayList<>();
        final Receipt receipt = new Receipt();
        receipt.setCreatedDate(new Date());
        Bitmap b = getBitmapFromImageView();
        if (b != null) {
            FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(b);
            FirebaseVisionTextDetector detector = FirebaseVision.getInstance().getVisionTextDetector();

            //the main method that extract the texts from image
            Task<FirebaseVisionText> result = detector.detectInImage(image).addOnSuccessListener(firebaseVisionText -> {
                for (FirebaseVisionText.Block block : firebaseVisionText.getBlocks()) {
                    for (FirebaseVisionText.Line line : block.getLines()) {
                        for (FirebaseVisionText.Element element : line.getElements()) {
                            elementList.add(String.valueOf(element));
                        }
                    }
                    Log.d("ciao1elementList3", String.valueOf(elementList));
                }
}

Это скорее element.getText () , чем String.valueOf(element).

Получает распознанный текст в виде строки.
