IWR6843AOPEVM: 3D People Counting Visualizer not working

Pablo Munoz

Part Number: IWR6843AOPEVM

I'm following this guide [1] to test te 3D people counting lab, but the visualizer is not working.

  • I successfully  flashed the binary to the EVM:  C:\ti\mmwave_industrial_toolbox_4_8_0\labs\people_counting\68xx_3D_people_counting\prebuilt_binaries\3D_people_count_68xx_demo.bin
  • I use the instructions here [2] to flash the binary and then I put it back to functional mode and reset it. 
  • The ports are detected as seen in the screenshots.
  • I enter the ports int he visualizer and hit connect and the connected message appears. 
  • then I tried to load a configuration by selecting a config file but nothing gets loaded. and It doesn't send any configuration when pressing the send configuration button. 

teraterm doesn't show anything on those ports. 

Any ideas how can I troubleshoot this lab? Not sure how to get any error info from the visualizer. nothings shows up. 

thanks

I successfully ran the OOTB and the Area Scanner for Zone Occupancy Detection labs.

    Hello,

    The links for the documents you are following did not stay in the message, so I am not sure what you are following exactly. Make sure you see the visualizer user's guide in the following folder.
    C:\ti\mmwave_industrial_toolbox_4_8_0\labs\people_counting\visualizer\docs

    Do you see the framecount incrementing at all in the visualizer after connecting? If you are using the .exe installer version of the GUI, please see the log file and check for any error messages printed there. The log file should be located in the following folder.

    C:\ti\mmWave_People_Counting_GUI\logData

    Regards,

    Thanks

    The issue was with the configuration file. I was loading the wrong config file. Then I load the one inside the lab folder and it worked. 

    Now. I have a question about those labs. 

    I understand the labs should be able to detect stationary people.  But in the three labs that I tried, the cloud points disappear once a person stay static.    3D People Counting, overhead 3D People Counting and Sense and Direct HVAC control

    Is there any configuration params I need to modify? or anything I'm missing here ?

    thanks

    Hello,

    For stationary people tracking, you will need to increase the static2free threshold in the tracking configuration and the person will need to be inside the static boundary box. Please see the following document for modifying these parameters.
