IWR6843ISK: People counting demo

IWR6843ISK: People counting demo: Regarding the output values

Part Number: IWR6843ISK

Hello everybody,

I am doing people counting demo using IWR6843ISK. I am saving the output of the demo. I need this for plotting is another way. My board is above 1.98m from the ground level with an elevation of 10 degrees.

So, when someone is walking the 'y' coordinate of the data should change from 0 to 5-6m as the person walk away from the board. But at about 5m the 'y' value I am getting is a maximum of 3m. Why is it so? Is there anything I should change whenever I run the demo? 

Thanks in advance.

Thanks and regards, 

Aleena N A

    Hi Aleena,

    Your board setup seems correct. Please confirm which version of the toolbox you are currently using and if you have made any modifications to the example code?

    It seems very odd that the Y coordinate is wrong. When moving does it seems to track you still? Or does it stop moving and get stuck at a fixed Y value? If it is connected to the visualizer, does the visualizer plot the target correctly? Also, are you loading in the default chirp parameters? These can be changed but maybe you modified them for a shorter range chirp?

    Regards,

    Hello Jackson, 

    Thank you for your reply. Also, I would like to know that what changes have to be done if we place the board at a height of 5m?

    Thank you,

    Hi Aleena,

    In general, the only change required should be the sensorPosition command in the CFG file. But you may have to adjust the tilt angle to cover the FOV you care about, and set the boundary box to match. We have not done much testing for this mounting height, but I expect no real change in performance.
