unity调用摄像头拍照

 我的unity调用摄像头拍照

因为做的是pc端的，所以不知道手机上效果是怎样的，据说代码是完全相同的

。

废话不说，上代码，

打开摄像头代码：
/// <summary>
/// Opens the camera
/// </summary>
/// <returns>The camera.</returns>
IEnumerator OpenCamera()
{
yield return Application.RequestUserAuthorization (UserAuthorization.WebCam);
if (Application.HasUserAuthorization (UserAuthorization.WebCam)) {
WebCamDevice[] devices = WebCamTexture.devices;
webCam = new WebCamTexture (devices [0].name, Screen.width, Screen.height, 12);
image_userIcon.texture = webCam;
webCam.Play ();
}
}保存图片代码如下：
/// <summary>
/// Gets the texture2d.
/// </summary>
/// <returns>The texture2d.</returns>
IEnumerator GetTexture2d()
{
yield return new WaitForEndOfFrame();
RectTransform rt = image_userIcon.GetComponent<RectTransform> ();
Vector2 v2Min = new Vector2( rt.anchorMin.x * Screen.width,rt.anchorMin.y * Screen.height);
Vector2 v2Max = new Vector2( rt.anchorMax.x * Screen.width,rt.anchorMax.y * Screen.height);
Texture2D t = new Texture2D((int)(v2Max.x-v2Min.x),(int)(v2Max.y-v2Min.y));//要保存图片的大小
//截取的区域
t.ReadPixels(new Rect (v2Min.x,v2Min.y,(int)(v2Max.x-v2Min.x),(int)(v2Max.y-v2Min.y)),0,0,false);
t.Apply();
image_userIcon.texture = t;
//把图片数据转换为byte数组

byte[] byt = t.EncodeToPNG();

//然后保存为图片

File.WriteAllBytes(Application.dataPath + "/StreamingAssets/shexiang/" + Time.time + ".jpg", byt);
webCam.Pause ();
}运行完这段效果大概是这样滴：
