What is the best way to detect in real time reflective targets on the Hololens 2 ?

Hello,

I am currently working on a project which requires to detect reflective targets on objects, and create holograms based on these targets.

I know I need Research Mode to get access to IR cameras, and I use this github https://github.com/microsoft/HoloLens2ForCV to help. I can get infrared camera pixels and then our image processing algorithms could do the trick.

I don't want to use Unity or any other engine, so I will be using the C++/WinRT (no OpenXR as I need to access Research Mode, only possible with WinRT)

Is this the best way to do this or is there another appropriate way that you could think of ?

Moreover, do you have any code that could help me in my work ? https://github.com/microsoft/HoloLens2ForCV help me greatly to access sensors but I don't seem to find some code that would help me create an hologram fixed in the world (I only found some in OpenXR and I have difficulties understanding the documentation about spatial anchors and coordinate systems - I understand how it works but I don't get how to change the position of an object independently of the device)

Thank you !

    Hello, Welcome to Microsoft Q&A,

    Yes, accessing the Depth & IR Camera via research mode on HoloLens is in the right direction. For using WinRT to implement Spatial Anchor, you can refer to Coordinate systems in DirectX - Mixed Reality | Microsoft Learn.

    For noise in the IR sensor, have both versions DEPTH_AHAT and DEPTH_LONG_THROW been tried?
