Unity Zxing QR码扫描仪集成

Question

我需要将Zxing和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.

Answer 1

我今天正在寻找将Zxing与vuforia整合在Unity中.

首先要从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(有些论文已经过时):

• 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.
