Camera Hack to make your Camera see Infrared!

My Friends,

Some Software to capture Video and Images, I use Emgu.CV which is an open C# Wrapper for OpenCV, a C++ Library I believe.

A short Video tutorial:

Some Code I use often, this is important for new Camera's that support Resolutions greater then: 640 x 480, the Default, works in Emgu.CV 3.2.0.2721

VideoCapture Camera = new VideoCapture(0);
Camera.SetCaptureProperty(CapProp.FrameWidth, 1280);
Camera.SetCaptureProperty(CapProp.FrameHeight, 720);
Camera.SetCaptureProperty(CapProp.Autofocus, 39);
Camera.SetCaptureProperty(CapProp.Fps, 60);

Very few, if any, set the important properties used here!

A small Windows Forms .NET 4.6 or above App for use:

namespace EmguCVWebcam
{



    #region Using Statements:



    using System;
    using System.Drawing;
    using System.Windows.Forms;


    using Emgu.CV;
    using Emgu.CV.CvEnum;
    using Emgu.CV.Structure;



    #endregion




    public partial class Form1 : Form
    {



        #region Fields:



        // Set the Video Name:
        private static string FileName = "Video.mp4";



        // Set the Video Name:
        private static string FilePath = @"\bin\Debug\Videos";



        // Config the CODEC:
        // VideoWriter.Fourcc('H', '2', '6', '4');
        private static int Codec = VideoWriter.Fourcc('F', 'M', 'P', '4');



        // Setup the Camera:
        private static Emgu.CV.VideoCapture Camera = new Emgu.CV.VideoCapture(1);



        // Init the Video Writer:
        private static VideoWriter videoWriter;



        #endregion

            Camera.SetCaptureProperty(CapProp.FrameHeight, FrameHeight);
            Camera.SetCaptureProperty(CapProp.Autofocus, 39);
            Camera.SetCaptureProperty(CapProp.Fps, Fps);

            // Init the VideoWriter:
            videoWriter = new VideoWriter(System.IO.Path.Combine(FilePath, FileName), Codec, Fps, new Size(FrameWidth, FrameHeight), true);

            // Go, as fast as the application can:
            Application.Idle += new EventHandler(CaptureFrames);
        }

        {


            // Get the Frame:
            Mat Frame = Camera.QueryFrame();

            // Image:
            Image<Bgr, byte> FrameImage = Frame.ToImage<Bgr, byte>();

            // Set the Image:
            pictureBox1.Image = FrameImage.ToBitmap();

            // Write the Video:
            videoWriter.Write(Frame);
        }



        /// <summary>
        /// On Form Closing Event.
        /// </summary>
        private void OnFormClosing(object sender, FormClosingEventArgs e)
        {

            // Dispose the Video Writer:
            if (videoWriter != null)
                videoWriter.Dispose();
        }
    }
}

This is about the simplest App one can use for .NET and Emgu.CV.

Best Wishes,
