我需要将Zxing与vuforia集成在Unity中制作QR码扫描应用程序吗? 我不知道如何将Zxing与Vuforia整合在一起。有人可以指导我如何做到这一点吗?我有Zxing .dll文件和Vuforia统一包。谢谢你。

我今天正在寻找将Zxing与vuforia整合在Unity中。
要做的第一件事就是从https://zxingnet.codeplex.com/下载dll并将unity dll复制到Plugins文件夹(应该在Assets文件夹中)
然后,我设法找到了一些例子(其中一些论文已经过时):
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
在合并这些示例并简化它们之后,我得到了类似的东西(放置在ARCamera预制件中):
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。

如果您使用Unity 5.x和64位Windows,则可能会收到错误
无法加载资产/插件/ QCARWrapper.dll
解决方案很简单,如问题Unity3d - Failed to load 'Assets/Plugins/QCARWrapper.dll'
中所述要将Vuforia与Unity 64位一起使用,只需将QCARWrapper DLL从/Plugins
移动到/Plugins/x86.
这些是DLL:
在Unity项目视图中选择QCARWrapper.bundle
(位于资产>插件下),以便在Unity Inspector中显示其设置更改Unity检查器中QCARWrapper.bundle
的设置从任何平台到独立+编辑。
比起它的魅力。

如果您在扫描过程中出现延迟,则此代码应为您提供帮助。我使用了KDelli的答案,并使用了另一个线程来解码qr。
using UnityEngine;
using System;
using System.Collections;
using Vuforia;
using System.Threading;
using ZXing;
using ZXing.QrCode;
using ZXing.Common;
[AddComponentMenu("System/VuforiaCamera")]
public class VuforiaCamera : MonoBehaviour
{
private bool cameraInitialized;
private BarcodeReader barCodeReader;
private bool isDecoding = false;
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 && !isDecoding)
{
try
{
var cameraFeed = CameraDevice.Instance.GetCameraImage(Image.PIXEL_FORMAT.RGB888);
if (cameraFeed == null)
{
return;
}
ThreadPool.QueueUserWorkItem(new WaitCallback(DecodeQr), cameraFeed);
}
catch (Exception e)
{
Debug.LogError(e.Message);
}
}
}
private void DecodeQr(object state){
isDecoding = true;
var cameraFeed = (Image)state;
var data = barCodeReader.Decode(cameraFeed.Pixels, cameraFeed.BufferWidth, cameraFeed.BufferHeight, RGBLuminanceSource.BitmapFormat.RGB24);
if (data != null)
{
// QRCode detected.
isDecoding = false;
}
else
{
isDecoding = false;
Debug.Log("No QR code detected !");
}
}
}
