提供されているJavaクライアントのGoogleビジョンを使用してGoogle Vision経由で画像に注釈を付けるときに例外が発生します。Google Vision Batch Javaクライアントライブラリの画像に
バッチclient.batchAnnotateImagesが発生し、特にこのコード：
public void processOCR(byte[] file)
{
List<AnnotateImageRequest> requests = new ArrayList<>();
ByteString imageByteString = ByteString.copyFrom(file);
Image img = Image.newBuilder().setContent(imageByteString).build();
Feature feat = Feature.newBuilder().setType(Type.DOCUMENT_TEXT_DETECTION).build();
AnnotateImageRequest request = AnnotateImageRequest.newBuilder().addFeatures(feat).setImage(img).build();
requests.add(request);
try (ImageAnnotatorClient client = ImageAnnotatorClient.create())
{
BatchAnnotateImagesResponse response = client.batchAnnotateImages(requests);
List<AnnotateImageResponse> responses = response.getResponsesList();
client.close();
//visionResultsDTO result = new visionResultsDTO();
String ParagraphText = "";
for (AnnotateImageResponse res : responses) {
if (res.hasError()) {
//throw exception.
return;
}
// For full list of available annotations, see http://g.co/cloud/vision/docs
TextAnnotation annotation = res.getFullTextAnnotation();
for (Page page: annotation.getPagesList()) {
String pageText = "";
for (Block block : page.getBlocksList()) {
String blockText = "";
for (Paragraph para : block.getParagraphsList()) {
String paraText = "";
for (Word word: para.getWordsList()) {
String wordText = "";
for (Symbol symbol: word.getSymbolsList()) {
wordText = wordText + symbol.getText();
}
paraText = paraText + wordText;
}
// Output Example using Paragraph:
blockText = blockText + paraText;
}
pageText = pageText + blockText;
}
}
ParagraphText = annotation.getText();
// result.setResultText(ParagraphText);
}
} catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
