我目前在 Vision API 文档上关注此示例:在此处找到
import com.google.cloud.vision.v1.*;
import com.google.cloud.vision.v1.Feature.Type;
import java.io.File;
import java.io.IOException;
import java.io.PrintStream;
import java.util.ArrayList;
import java.util.List;
public class VisionApiTest {
public static void main(String... args) throws Exception {
PrintStream stream = new PrintStream(new File("src/test.txt"));
detectTextGcs("https://www.w3.org/TR/SVGTiny12/examples/textArea01.png", stream);
}
public static void detectTextGcs(String gcsPath, PrintStream out) throws Exception, IOException {
List<AnnotateImageRequest> requests = new ArrayList<>();
ImageSource imgSource = ImageSource.newBuilder().setGcsImageUri(gcsPath).build();
Image img = Image.newBuilder().setSource(imgSource).build();
Feature feat = Feature.newBuilder().setType(Type.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();
for (AnnotateImageResponse res : responses) {
if (res.hasError()) {
out.printf("Error: %s\n", res.getError().getMessage());
return;
}
// For full list of available annotations, see http://g.co/cloud/vision/docs
for (EntityAnnotation annotation : res.getTextAnnotationsList()) {
out.printf("Text: %s\n", annotation.getDescription());
out.printf("Position : %s\n", annotation.getBoundingPoly());
}
}
}
}
}
将 gcsPath 字符串传入示例中的 detectTextGcs 方法后,出现错误:“错误:指定的 GCS 路径无效:https ://www.w3.org/TR/SVGTiny12/examples/textArea01.png ”
我期待 PrintStream 对象将图片中保存的文本写入文件,即“明天,\n明天,和\n明天;等等等等……”。在上面提到的 Vision API 文档页面上尝试 API 后,它工作正常,但在 IntelliJ 中不行。
任何帮助是极大的赞赏。谢谢你。(如果这不是一个措辞好的问题,请原谅我,这是我第一次发帖)
