IWR6843ISK: Long range people detection

Aleena N A

Part Number: IWR6843ISK

Hello, 

I am doing long-range people detection using IWR6843ISK. I have done as per the user guide provided (https://dev.ti.com/tirex/explore/node?node=AHoEHc6j2uX.XSbB65w0Tg__VLyFKFf__LATEST&r=VLyFKFf__3.6.2). I am getting the detections. I have used the visualizer given in the user guide(traffic monitoring visualizer)

I want the output as we get from the people counting demo i.e., boxes on detected people, using mm_wave people counting gui. I tried but I got just points in the visualizer. Also, I want a 30m range detection. Is it possible to make it? 

Thanks in advance.

Thanks and regards,

Aleena N A

    Hello Aleena,

    This demo is also compatible with the python based visualizer used for the 3D people counting. Just make sure to select the long range people counting demo from the drop down when connecting. The UART parser works and you will see the familiar boxes drawn. The graph of this visualizer is not optimized for a large area display, which is why it is not typically recommended.

    Hello,

    The obtained data from the visualizer is saved as .txt file but in HEX format? How to interpret that data?

    Hello,

    This is a hex version of the UART output. So you can follow the output format of the OOB_demo for this lab to know how to parse the output. You can use the parser scripts as a starting point.

    C:\ti\mmwave_industrial_toolbox_4_7_0\labs\out_of_box_demo\common\docs

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\parser_scripts

    Hello Jackson,

    I have the output from long range detection as follows,

     . My problem is how to understand this data.

    I have used parser scripts in "C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\parser_scripts" for .dat files obtained from OOB demos and successfully converted into .csv files. But when I used the same code for parsing the output from long range detection I got error as follows,

     

    How to solve this?

    Thanks and Regards,

    Hi Aleena,

    The output format can be seen in the following document.

    C:\ti\mmwave_industrial_toolbox_4_7_0\labs\out_of_box_demo\common\docs\understanding_oob_uart_data.pdf

    That parser script might not be set up to filter the text file instead of a binary file. You will need to modify the script to read the text file info. 

    Regards,
