Merhaba,<\/p>\n

Bu i\u00e7eri\u011fimizde AForge.NET k\u00fct\u00fcphanelerini kullanarak kendi k\u00fc\u00e7\u00fck savunma sanayimizin in\u015fas\u0131na ilk ad\u0131m\u0131m\u0131z\u0131 ataca\u011f\u0131z \ud83d\ude42 Hi\u00e7 \u00f6yle u\u00e7an ka\u00e7an bir\u015feye ihtiyac\u0131m\u0131z yok. Bir adet bilgisayar ve bir adet dahili yahut harici kamera sayesinde elde etti\u011fimiz g\u00f6r\u00fcnt\u00fcler \u00fczerinde hareketleri alg\u0131yacak, hareket unsurlar\u0131n\u0131 farkl\u0131 algoritmalar e\u015fli\u011finde alg\u0131layarak vurgulayacak, t\u00fcm bunlar\u0131n yan\u0131nda hareketin alg\u0131land\u0131\u011f\u0131 herhangi bir anda istedi\u011fimiz i\u015flemleri(\u00f6rn; mail ya da mesaj g\u00f6nderme) devreye sokabilece\u011fiz. Hadi buyrun hi\u00e7 vakit kaybetmeden \u00e7al\u0131\u015fmam\u0131za ba\u015flayal\u0131m.<\/p>\n

\u00c7al\u0131\u015fmaya e\u015flik etmek istiyorsan\u0131z e\u011fer bir adet Windows Form projesi olu\u015fturarak formun \u00fczerinde halihaz\u0131rda bir adet PictureBox nesnesi tan\u0131mlaman\u0131z yeterli olacakt\u0131r.<\/p>\n

\nHer\u015feyden \u00f6nce ilgili projemize AForge.NET k\u00fct\u00fcphanelerini<\/a> entegre etmeyi unutmuyoruz.<\/p><\/blockquote>\n

\u00d6ncelikle, hareketleri alg\u0131layabilmek i\u00e7in sistemdeki kameralara eri\u015ferek g\u00f6r\u00fcnt\u00fcleri elde etmemiz gerekmektedir. O y\u00fczden hareket algoritmalar\u0131na gelmeden \u00f6nce hangi kamera \u00fczerinde \u00e7al\u0131\u015faca\u011f\u0131m\u0131z\u0131 belirlememiz gerekmektedir.<\/p>\n

\r\n        public void KameralariGetir()\r\n        {\r\n            VideoCaptureDevice FinalVideoSource;\r\n            FilterInfoCollection VideoCaptuerDevices;\r\n            VideoCaptuerDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);\r\n            FinalVideoSource = new VideoCaptureDevice(VideoCaptuerDevices[0].MonikerString);\r\n            FinalVideoSource.NewFrame += FinalVideoSource_NewFrame;\r\n            FinalVideoSource.DesiredFrameRate = 500;\r\n            FinalVideoSource.DesiredFrameSize = new Size(1, 500);\r\n            FinalVideoSource.Start();\r\n        }\r\n        private void FinalVideoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)\r\n        {\r\n            Bitmap image = (Bitmap)eventArgs.Frame.Clone();\r\n            pictureBox1.Image = image;\r\n        }\r\n        private void Form1_Load(object sender, EventArgs e)\r\n        {\r\n            KameralariGetir();\r\n        }\r\n<\/pre>\n
Yukar\u0131daki yapm\u0131\u015f oldu\u011fumuz \u00e7al\u0131\u015fma neticesinde sistemdeki kameralar\u0131 elde ederek \u00e7al\u0131\u015faca\u011f\u0131m\u0131z kameray\u0131 belirlemi\u015f ve kameradan elde edilen g\u00f6r\u00fcnt\u00fcleri PictureBox nesnesine anl\u0131k olarak g\u00f6ndermi\u015f bulunmaktay\u0131z.<\/p>\n
Evet… \u015eimdi kameradan elde edilen g\u00f6r\u00fcnt\u00fcler \u00fczerinde hareketleri alg\u0131layacak algoritmalar\u0131m\u0131z\u0131 olu\u015fturabiliriz.<\/p>\n
Bu i\u015flemi yaparken \u00e7al\u0131\u015faca\u011f\u0131m\u0131z alan NewFrameEventHandler delegesiyle i\u015faretlenmi\u015f olan “FinalVideoSource_NewFrame” metodumuz olacakt\u0131r. \u00c7\u00fcnk\u00fc bu metot her bir g\u00f6r\u00fcnt\u00fc geldi\u011finde tetiklenmekte ve o anki elde edilen g\u00f6r\u00fcnt\u00fcy\u00fc bir \u00f6ncekiyle k\u0131yaslama imkan\u0131 tan\u0131maktad\u0131r.<\/p>\n
Ayriyetten, elde edilen g\u00f6r\u00fcnt\u00fc \u00fczerinde yap\u0131lacak hareket alg\u0131lamas\u0131n\u0131 hangi algoritmayla icra edece\u011fimizide belirtmemiz gerekmektedir. Bu i\u015flem i\u00e7in AForge.NET k\u00fct\u00fcphanesinde;<\/p>\n
