how to save color video and depth map in Kinect

Question

Hello,

I am very new in Kinect coding, so I am stucked at a very basic problem, I want to save color video and dept map, I guess that for this to be done, I must modify skeletal viewer example.

I would appreciate very much, if you give me an answer as detailed as possible

Thank you

Do you want to save the single images?

 

If so, use the following code snippet:

 

        private void SaveImage(BitmapSource image)
        {
            System.IO.FileStream stream = new System.IO.FileStream(@"C:\YOUR_FOLDER_HERE.jpg", System.IO.FileMode.Create);
            JpegBitmapEncoder encoder = new JpegBitmapEncoder();

            encoder.FlipHorizontal = true;
            encoder.FlipVertical = false;
            encoder.QualityLevel = 30;
            encoder.Frames.Add(BitmapFrame.Create(image));
            encoder.Save(stream);
            stream.Close();
        }

 

Call this method after you created your image in the eventhandlers (e.g.)

        /// <summary>
        /// Eventhandler, triggered when new color frame is available
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        void nui_ColorFrameReady(object sender, ImageFrameReadyEventArgs e)
        {
            // 32-bit per pixel, RGBA image
            PlanarImage Image = e.ImageFrame.Image;
            BitmapSource image  = BitmapSource.Create(
                Image.Width, Image.Height, 96, 96, PixelFormats.Bgr32, null, Image.Bits, Image.Width * Image.BytesPerPixel);
            video.Source = image;
            SaveImage(image);
        }

Cheers

Thank you for your answer,

 

When I did what you said, it gives an error which says the access to C:\YOUR_FOLDER_HERE.jpg is denied

Answer 3

Dude, you have to change your path.

I called it YOUR_FOLDER_HERE that you take a valid folder here.

 

Check for a HDD or USB Stick where you have the rights to write files.

Maybe in your case you dont have a HDD or USB with the label C.

Or go into a folder of your hdd were you have write rights!

 

I hope you understand, that your problem is the path, were the file should be created!

So maybe you have to change the line

System.IO.FileStream stream = new System.IO.FileStream(@"C:\YOUR_FOLDER_HERE.jpg", System.IO.FileMode.Create);

to

System.IO.FileStream stream = new System.IO.FileStream(@"D:\myfirstimage.jpg", System.IO.FileMode.Create);

or

System.IO.FileStream stream = new System.IO.FileStream("D:\myfirstimage.jpg", System.IO.FileMode.Create);

 

Check it out. If you cant find a solution check google for: " System.IO.FileStream C Sharp"

 

Cheers!

 

 

 

Answer 4

You are right, the problem was in path, Thank you for your help,

I also want to save depth map, probably I must change the method nui_DepthFrameReady, I would try to do same steps we did while saving color image.

But, it is highly probable that I may be stumped, so I would need your help,

Also I want to save these color images and depth maps as video, I would appreciate very much if you tell a solution to this problem.

Thank you again

 

 

Answer 5

Hi,

Code above is very helpful. But i am looking for something can record the video (not single image). Is there any way to do that? Can you guys please help me with it? I am using skeletonviewer sample program.

 

Also is there any way to superimpose(overlay) vga view on skeleton view (or the other way) ?

 

Your help will be highly appreciated.

 

Thanks.

You can use the kinect toolbox to record the depth data and skeleton data but i am not so sure that you can record the color view with it.
