IWR6843ISK-ODS: ODS_6m_default.cfg

Part Number: IWR6843ISK-ODS

Hello,

We tried the 3D TI people counting with ODS using the embedded ODS_6m_default.cfg config.

And we found that it can only detect large movement when a person is walking/jumping. It cannot detect person standing or sitting with minor movement (no point cloud with minor movement.) We tried the online mmWave sensing estimator, but cannot get a very small velocity resolution due to the restriction of the radar cube size.

Do you have any other sample cfg for the people counting demo that can detect person sitting with minor movement such as breathing or typing only.

Thanks,
Nick

    Hi Nick,

    Do you have any results, pictures, or screenshots you can share?

    We'll try to have an answer for you tomorrow.

    Cheers,

    Hi Nick,

    You can try the following config:

    sensorStop

    adcCfg 2 1
    adcbufCfg -1 0 1 1 1

    staticBoundaryBox -2 2 2 8.5 -2 2

    allocationParam 200 800 0.1 15 0.5 20
    trackingCfg 1 2 1000 20 67 105 50
    sensorStart

    This will be very sensitive to small movements, but may struggle with people who are walking quickly. Also note it will probably require tuning to get tracker functioning well.
