Low frame rate of depth and ahat sensors

Open xyq3q opened this issue 9 months ago • 1 comments

Hi, I ran the demo program client_stream_rm_depth_ahat.py and only added code to measure the frame rate. No other parameters, including the divisor, were changed. However, I noticed that the frame rate dropped to 15 or even 5 after running for a while. I had to restart client_stream_rm_depth_ahat.py to restore the frame rate to 45. How can I resolve this issue?

Hi, The depth sensors have some kind of adaptive framerate. Long throw can vary between 1-5 FPS, and AHAT framerate is reduced if the hand tracker does not detect user hands. See https://github.com/microsoft/HoloLens2ForCV/issues/42. Currently, there is no way to force a constant framerate other than to keep hands always in view.
