[Feature Request] How to lower frame rate in nuitrack config?

Nuitrack SDK Feature Requests
1

Hello. I’ve been used Nuitrack AI and Pro so far. And I am using realsense 455D model.

i have some problem.

I have to use nuitrack on Celeron or i3. So, To improve perfermance, I decided to lower frame rate.

However, I cannot find options that control frame rate in nuitrack.config .

Do you have any good solution?

Thank you.

Hi @jacob

The are several depth video modes available for Realsense D455. Pick video mode from the list below and set values of Width, Height adding FPS option manually in nuitrack.config. For example:

"Realsense2Module": {
        "DeviceHardwareReset": false,
        "Depth": {
            "ProcessWidth": 256,
            "ProcessHeight": 144,
            "FPS": 90,
            "ProcessMaxDepth": 5000
        },

Available depth video modes:
Index | Width | Height | FPS
0 | 1280 | 720 | 30
1 | 1280 | 720 | 15
2 | 1280 | 720 | 5
3 | 848 | 480 | 90
4 | 848 | 480 | 60
5 | 848 | 480 | 30
6 | 848 | 480 | 15
7 | 848 | 480 | 5
8 | 848 | 100 | 100
9 | 640 | 480 | 90
10 | 640 | 480 | 60
11 | 640 | 480 | 30
12 | 640 | 480 | 15
13 | 640 | 480 | 5
14 | 640 | 360 | 90
15 | 640 | 360 | 60

As a side note - currently we don’t have direct control of frameskip/fps as a feature of Nuitrack itself (only have non-documented indirect / feedback control of frameskip by CPU load), but we are considering it.
Please let us know whether workaround by @a.bragin works for you.

Thank you guys.

I tried to lower resolution and fps, but it hasn’t shown big improvement.

So, I concluded not to use lower cpu (i.e. i3) for AI version.

Anyway Thank you for your replay. It would be good information for the future work.
