通过意向使用基于的tesseract-OCR [英] Using a Tesseract-based OCR via Intent

问题描述

我需要我的应用程序通过摄像头读取文本。我知道有对的tesseract库，做到这一点，但我真的preFER如果有一个应用程序，可以处理意图通过摄像头读取文本，就像Xzing不读QR codeS。

I need my app to read text via Camera. I know there's the Tesseract library which does this, but I'd really prefer if there was an app that can handle Intents to read text via Camera, like Xzing does for reading QR codes.

有没有这样的应用程序？

Is there such an app?

推荐答案

目前还不能在谷歌Play上做到这一点的应用程序。

There isn't currently an app on Google Play that does this.

我想过做一个，但可能用例这样的应用程序有所不同比，多说，扫描QR code。有不同的可能的方案：

I've thought about making one, but the possible use cases for such an app vary much more than for, say, scanning a QR code. There are different possible scenarios:

• 车牌识别


• 识别为LCD 7段显示器


• 韩国OCR


• OCR为个性化文字


• OCR与阴影或光照不均

在不同的情景present如何处理图像的挑战。意图通过这样一个应用程序的请求很可能需要至少指定的阈值的类型使用pre-处理图像的语言/ traineddata文件中使用沿。

The different scenarios present a challenge for how to handle the image. A request to such an app via Intent would probably need to specify at least the type of thresholding to use for pre-processing the image along with the language/traineddata file to use.
