带有Node.js的Google Vision API文本检测设置了语言提示

问题描述

我正在将@google-cloud/vision与Node.js一起使用

I'm using @google-cloud/vision with Node.js

我使用以下示例代码

async function quickstart() {
  try {
    // Imports the Google Cloud client library
    const vision = require('@google-cloud/vision');

    // Creates a client
    const client = new vision.ImageAnnotatorClient();

    // Performs label detection on the image file
    const [result] = await client.textDetection('./test.jpg');
    const texts = result.textAnnotations;
    console.log('Text:');
    texts.forEach((text: string) => console.log(text));
  } catch (err) {
    console.log(err);
  }
}

这当前正在工作，并且返回英文文本和数字.我在图像中使用了Vision API的实验语言.如何将语言提示设置为node.js API中指定的文档?

This is currently working working and return english texts and numbers. I have texts in image which Vision API's Experimental languages. How can I set the language hint as document specified in node.js API?

推荐答案

您可以使用batchAnnotateImages方法.例如:类似

You can use the batchAnnotateImages method. Eg: something like:

const request = {
    features: [{type: 'TEXT_DETECTION'}],
    imageContext: {
        languageHints: ["en-t-i0-handwrit"]
    },
    <other parts of your request>
};
const [response] = await imageAnnotatorClient.batchAnnotateImages({
    requests: [request],
});
