How am I be able to capture the distance of a person being tracked in a video stream?

[SWong19]

Hi everyone, I want to know how can I utilise RealSense D435 to obtain the distance from a person front facing toward the camera in a video stream?

To be more specific, I wish to obtain and track their distance either based on their face or body skeleton. I'm currently using C# to develop this project.

I already have my code partially done but it's just basic that is to obtain the video stream but I have no idea how can I identify their distance from the camera and display it.

Thanks in advance.

If most of your code is done, you may be able to obtain the distance by converting the C language sample below to C# .

If more complex detection of people specifically is required, you may need to combine SDK 2.0 with a person tracking module in the OpenCV software platform.

Thank you very much. But sadly I have no fundamentals in C language so it will take some time for me to digest the code.

I located C# depth code examples in the .NET wrapper section of the SDK documentation.
