Blocktype BARCODE：Cloud Vision 可以读取条码吗？如何读取？

Question

这是我的第一个问题，所以我会尽量做到相关。我对使用 Cloud Vision 处理一些文档很感兴趣，因为我需要 OCR 功能。我也正好需要读条码，目前我已经用ZXing实现了

我在 OCR ( https://cloud.google.com/vision/docs/reference/rest/v1/images/annotate#BlockType ) 中偶然发现了 BARCODE 块类型，但我没有设法生成这样的块，即使图像包含仅条代码。

因此问题来了：该功能是否已实现，如果已实现，我们如何才能让它发挥作用？感谢您的宝贵时间！

注：

我看过那些相关的问题：

Does google cloud vision OCR support bar code reading?

但它们并不能满足我，因为我同时需要条形码读取和 OCR，而且我只在后端工作，没有用户参与。

Answer 1

如果您向我们展示了您尝试过的代码以及您从代码（以及您使用的图像）中得到的响应，这会更容易。

为了获得返回的 blockType 条形码，首先确保您使用的是 textAnnotation. The returned response should contain a textAnnotation which can be broken down to pages. From the Page, you can get blocks. If there's a barcode in the image that you are trying to annotate, you should get a barcode blockType 返回。

测试您的图像，看看是否可以返回条形码 blockType。

看到您的代码（基本上是 Cloud SDK）后，这显然是一个应该报告的问题。请使用我们的 Public Issue Tracker to track the issue. Alternatively, you can also report the issue with the API devs in Github issues.
