Unity3D使用C#脚本调用外置摄像头拍摄照片,并转化成byte数组

  TakePhoto.cs

  IEnumerator Start() 
  {
        
        //获取摄像头
        yield return Application.RequestUserAuthorization(UserAuthorization.WebCam);
        if(Application.HasUserAuthorization(UserAuthorization.WebCam))
        {

            WebCamDevice[] devices = WebCamTexture.devices;
            if(devices !=null)
            {
          //获取设备名称 deviceName
= devices[0].name; tex = new WebCamTexture(deviceName,400,300,12); tex.Play(); } } } //获取像素 private byte[] GetPhotoPixel(WebCamTexture ca) { Texture2D texture = new Texture2D (ca.width,ca.height); int y = 0; while (y < texture.height) { int x = 0; while (x < texture.width) { UnityEngine.Color color = ca.GetPixel(x,y); texture.SetPixel(x,y,color); ++x; } ++y; } texture.Apply (); // texture.name = name ; byte[] pngData =http://www.mamicode.com/ GetJpgData (texture); return pngData ; } //控制照片大小 private byte[] GetJpgData(Texture2D te) { byte[] data= http://www.mamicode.com/null ; int quelity = 75 ; while(quelity > 20) { data = te.EncodeToJPG(quelity); int size = data.Length/1024; if( size > 30 ) { quelity -=5; } else { break ; } } return data ; }
