Calculate tracking accuracy #4

Open Nacy09 opened 3 months ago

Nacy09 commented 3 months ago

Hello， I have successfully implemented a tracking tool in HoloLens2, and I only have HoloLens2 devices. How can I calculate the tracking accuracy? Thank you very, very much for your or anyones help!

Hey, The tracking accuracy depends on the camera calibration of the sensors in the headset as well as the ToF depth readings. You can test accuracy using an external system such as OptiTrack or a linear stage. The tracking library itself cannot give you reliable information about accuracy without external tools. In a very basic way you could move the marker from one position to another manually, measure the distance and compare it to the readings from the library. I recommend reading some research papers that focus on accuracy evaluation if you want to do a more comprehensive analysis, as there are numerous works that focus on accuracy measurements. Hope this helps :)

Hello， I don't have an external device at the moment, do you have any paper recommendations on manual assessment accuracy?

Unfortunately I do not have papers that tackle accuracy measurements without something like a linear stage, a second tracking system or a robot.
