生成和识别二维码U3d

转：http://www.manew.com/thread-47945-1-1.html?_dsign=3548f138

工作繁忙，很久没有更新，略表歉意。关于二维码的生成和识别网上泛泛看了一些，ZXing用的比较多。

ZXing的官网是http://zxingnet.codeplex.com/，它在github有源码，有兴趣的可以自己翻翻看看。

publicclass GenerateQRCode : MonoBehaviour {

publicTexture2D _texture;
publicstring content;
Color32[] webCameraTextureData;
privateBarcodeReader barcodeReader;

voidStart()
{
_texture = newTexture2D(256, 256);
content = "http://www.baidu.com";
barcodeReader = newBarcodeReader();
Generateimages();
Recognition();
}

//生成图片
voidGenerateimages()
{
var textForEncoding = content;
if(textForEncoding != null)
{
var color32 = Encode(textForEncoding, _texture.width, _texture.height);
_texture.SetPixels32(color32);
_texture.Apply();
//赋值给webCameraTextureData用于识别
webCameraTextureData = color32;
}
}
//生成二维码信息
privatestatic Color32[] Encode(stringtextForEncoding, intwidth, intheight)
{
var writer = newBarcodeWriter
{
Format = BarcodeFormat.QR_CODE,
Options = newQrCodeEncodingOptions
{
Height = height,
Width = width
}
};
returnwriter.Write(textForEncoding);
}

voidOnGUI()
{
GUI.DrawTexture(newRect(0, 0, 256, 256), _texture);
}

//识别二维码
publicvoid Recognition()
{
var data = barcodeReader.Decode(webCameraTextureData, _texture.width, _texture.height);
switch(data.BarcodeFormat)
{
caseBarcodeFormat.QR_CODE:
break;
}
Debug.Log(data);
}

}

整体代码还是比较简单，为了方便，我识别直接用了生成的二维码，有需求的可以换成从摄像头获取。
