推荐答案

我今天想在 Unity 中将 Zxing 与 vuforia 集成.

I was looking for integrating Zxing with vuforia in Unity today.

首先要做的是从以下位置下载 dll:https://zxingnet.codeplex.com/ 并将 unity dll 复制到您的 Plugins 文件夹(应该在 Assets 文件夹中)

The first thing to do is to download the dll from : https://zxingnet.codeplex.com/ and copy the unity dll into your Plugins folder (which should be in the Assets folder)

然后，我设法找到了一些例子(有些论文已经过时了):

Then, I managed to found some examples (some of theses is outdated) :

• http://ydaira.blogspot.fr/2012/09/how-to-decode-qr-codes-using-unity3d.html

https://github.com/Redth/ZXing.Net/blob/master/Clients/VuforiaDemo/Assets/VuforiaScanner.cs

合并这些例子并简化它们后，我得到了这样的东西(放置在ARCamera预制件上):

After merging theses examples and simplify them, I got something like this (which is placed of the ARCamera prefab) :

using UnityEngine;
using System;
using System.Collections;

using Vuforia;

using System.Threading;

using ZXing;
using ZXing.QrCode;
using ZXing.Common;


[AddComponentMenu("System/VuforiaScanner")]
public class VuforiaScanner : MonoBehaviour
{    
    private bool cameraInitialized;

    private BarcodeReader barCodeReader;

    void Start()
    {        
        barCodeReader = new BarcodeReader();
        StartCoroutine(InitializeCamera());
    }

    private IEnumerator InitializeCamera()
    {
        // Waiting a little seem to avoid the Vuforia's crashes.
        yield return new WaitForSeconds(1.25f);

        var isFrameFormatSet = CameraDevice.Instance.SetFrameFormat(Image.PIXEL_FORMAT.RGB888, true);
        Debug.Log(String.Format("FormatSet : {0}", isFrameFormatSet));

        // Force autofocus.
        var isAutoFocus = CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
        if (!isAutoFocus)
        {
            CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_NORMAL);
        }
        Debug.Log(String.Format("AutoFocus : {0}", isAutoFocus));
        cameraInitialized = true;
    }

    private void Update()
    {
        if (cameraInitialized)
        {
            try
            {
                var cameraFeed = CameraDevice.Instance.GetCameraImage(Image.PIXEL_FORMAT.RGB888);
                if (cameraFeed == null)
                {
                    return;
                }
                var data = barCodeReader.Decode(cameraFeed.Pixels, cameraFeed.BufferWidth, cameraFeed.BufferHeight, RGBLuminanceSource.BitmapFormat.RGB24);
                if (data != null)
                {
                    // QRCode detected.
                    Debug.Log(data.Text);
                }
                else
                {
                    Debug.Log("No QR code detected !");
                }
            }
            catch (Exception e)
            {
                Debug.LogError(e.Message);
            }
        }
    }    
}

我设法让它在 AVD(Android 虚拟设备)中运行，因此它可以在真实设备上运行.

I manage to make it works in an AVD (Android Virtual Device), so it will works on a real device.
