将Vision VNTextObservation转换为String [英] Converting a Vision VNTextObservation to a String
问题描述
我正在查看Apple的 Vision API文档，我看到了几个类与 UIImages中的文本检测有关：
I'm looking through the Apple's Vision API documentation and I see a couple of classes that relate to text detection in UIImages:
1） class VNDetectTextRectanglesRequest
看起来他们可以检测到字符，但我没有看到对字符做任何事情的方法。一旦检测到字符，您将如何将它们转换为可以通过 <解释的内容code> NSLinguisticTagger ？
It looks like they can detect characters, but I don't see a means to do anything with the characters. Once you've got characters detected, how would you go about turning them into something that can be interpreted by NSLinguisticTagger?
这是一篇简短概述 愿景 。
Here's a post that is a brief overview of Vision.

推荐答案
SwiftOCR
我只是让SwiftOCR使用少量文本。
I just got SwiftOCR to work with small sets of text.
https： //github.com/garnele007/SwiftOCR
使用
https://github.com/Swift-AI/Swift-AI
使用NeuralNet-MNIST模型进行文本识别。
which uses NeuralNet-MNIST model for text recognition.
TODO：VNTextObservation> SwiftOCR
一旦我将其连接到另一个，就会使用VNTextObservation发布它的示例。
Will post example of it using VNTextObservation once I have it one connected to the other.
OpenCV + Tesseract OCR
我尝试使用OpenCV + Tesseract但是编译错误然后找到SwiftOCR。
I tried to use OpenCV + Tesseract but got compile errors then found SwiftOCR.
另请参阅：谷歌视觉iOS
注意谷歌视觉文字识别 - Android sdk有文本检测，但也有iOS co coapod。所以请密切关注它，因为最终应该向iOS添加文本识别。
Note Google Vision Text Recognition - Android sdk has text detection but also has iOS cocoapod. So keep an eye on it as should add text recognition to the iOS eventually.

//更正：刚试过但是只有Android版本的sdk支持文本检测。
//Correction: just tried it but only Android version of the sdk supports text detection.
