如何使用电脑摄像头读取二维码并打开网站 [Java] [英] How to use a computer's webcam to read a qr code and open a website [Java]

问题描述

首先让我简要描述一下我要完成的任务:

First let me provide a brief description of what I am trying to accomplish:

我正在尝试创建一个 Java 程序，该程序可以扫描/读取位于计算机网络摄像头前面的二维码(我将使用的二维码都只包含存储在其中的 url 信息).从二维码中获取到url后，我想让程序自动跳转到url.

I am trying to create a java program that can scan/read a qr code positioned in front of the computer webcam (The QR codes I would be using would all just have url information stored within them). After obtaining the url from the qr code I want to have the program automatically go to the url.

我的第一个问题是如何使用带有 Java 的计算机网络摄像头.我的第二个问题是，一旦捕获到二维码，我该如何解码.

My first question is how do I use a computer webcam with Java. My second question is how do I decode a QR code once one is captured.

感谢您的帮助.

或者，是否可以使用 .net 读取二维码?

Alternatively is it possible to read qr-codes with .net?

推荐答案

在 Java 中，您可以使用 LTI Civil 从网络摄像头捕获图像.然后将捕获的图像传递给 ZXing 以解码二维码.

In Java you could use LTI Civil to capture images from a webcam. Then pass the captured images to ZXing to decode the QR codes.

在 .NET 中，您可以使用 AForge 然后将图像传递给 ZXing.NET.

In .NET you could capture the images with AForge and then pass the images to ZXing.NET.

如果您需要更多信息，您应该提出更具体的问题.

If you need more information, you should ask a more specific question.
