IWR1642BOOST: Regarding people counting application

Jungsang Yoo

Part Number: IWR1642BOOST

Hi

i configured the application for long range,

it seemed good before pressing Start button,

however after that, as you see the picture below, the range it can detect is shrunk.

would you tell me what i missed out and tell me how to fix it ?

thanks

    Hello Jungsang,

    This is just an error with the GUI - it is drawing the field of view of the default chirp. This does not actually affect the range the radar can detect. It will always default to draw the radar area to match the default chirp - but if you have loaded a different longer range chirp you can see detection as expected (it is not limited by the drawing of the radar FOV).

    You can see an example here:

    Hello Amanda

    Your is much better than mine !
    It blows my mind away !

    Regards

    .....

    i found it out somehow !

    thanks

    Hello Jungsang,

    This is from the long range people detection experiment please see the details here:
    dev.ti.com/.../

    To replicate please note that the mounting height and angle are different from standard people counting to be able to see out to 50m.

    You can pull the chirp configuration from here - use the Case 5 50m:
    dev.ti.com/.../

    Please note that the 50m configuration uses the .bin image from:
    Traffic monitoring
    dev.ti.com/.../

    Hi Amanda, I'm using the 30m chirp configuration and xwr16xx_pcount_lab.bin. Not only the FOV gets shrunk but also the detections stay inside escalated to the 5m FOV, so something in the 15 m range appears as in 3 m in the GUI. Also, detections disappear when they get out of the "theorical" 5m FOV.

    In the first video from 1:50 to 2:04 you can see clearly how a person walks 14m away and in the gui appears as 0-5 m, also it disappears when it surpasses the FOV.

    If I leave the GUI from 0 to 5 m it still makes the detections (from 0 to 30m) inside the 0-5m range.

    Also in the fHistRT.mat file I'm getting strange values on the position and velocity, Y ranges from 0 to 3.

    What am I doing wrong?

    also, the people count demo works correctly when I use the default cfg or 14m office space cfg. I need to use a 30 m cfg, is this possible?

    Hello Carlos,

    Please note that the 30m chirp (updated to a 50m chirp in more recent version of the Industrial Toolbox) uses the .bin from the Traffic Monitoring Lab.

    Please see the links from my response above - I've linked to the Traffic Monitoring lab required..

    The experiment link specifies the exact chirp cfg and bin combination needed. Also please pay attention to the setup and mounting details for the down tilt of the EVM as this will affect the max range you can detect people.
