D435: Convert Videoframe to Bitmap in C#

idata — Mon, 09 Apr 2018 12:56:52 GMT

Hello,

i am looking for the fastest conversion of a Videoframe to a Bitmap.

Currently i am doing this:

Bitmap bmp = new Bitmap(frame.Width, frame.Height, frame.Stride, System.Drawing.Imaging.Pixelformat.Format24bppRgb, frame.Data);

Afterwards i am doing a face detection and recognition with the Bitmap and display it through a System.Windows.Controls.Image.

Using a regular Webcam or the R200 works smooth, but the output is laggy when i am using the D435.

Any ideas?

RealSense SDK 2.0 has a sample program for saving a frame to disk as a PNG image.

Edit: I re-read and saw that you need the code in C# . I do not have a C# sample for saving frames as images, unfortunately.

Hey MartyG,

i edited it afterwards, so that was my mistake missing the c# part.

Edit: in case you did read my second question, i picked the wrong format, i fixed that now

Thanks Niko.

If you are doing the conversion of the frame to bitmap just for the purposes of feeding it into your face detection routine, you may be interested in new skeletal tracking software for the D415 and D435 called Nuitrack that can do full-body tracking and face recognition.
