IWR1642BOOST: Possible to extend people counting demo with direction detection?

Part Number: IWR1642BOOST

Hello,

I am already using the people counting demo on my ES2.0 device and was able to extend it with a counter for the total number of people who passed through a defined area. Now I want to count the number of people and their direction, as you suggested in one of the mmW videos. I already tried different approaches but nothing worked out.

Do you have any good solutions for my Problem?

Best regards

Patrick

    Hi Patrick,

    The EVM will send velocity and acceleration information for each tracked person to the GUI.  If you can edit the GUI, there is a variable called S. It is stored in the Fhist as FHist.targetList.S. S is a 6 by N matrix, where N is the number of tracked people. Format of Each column is as follows:

    1. Position X
    2. Position Y
    3. Velocity X
    4. Velocity Y
    5. Acceleration X
    6. Acceleration Y

    If you are interested in how this is seen inside the C code, this data is passed across the UART in task_mbox.c inside the MSS.  The format of the output is described in mmw_output.h in the common folder. See line 235 - MmwDemo_output_message_target_t.

    Regards,

    Justin
