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：
