IWR1443BOOST: Depth map generation from the mmWave sensor board

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443

Dear E2E community,

I am working on the IWR1443 sensor board and able to run sample demos.

I am interested in DEPTH MAP generation using the sensor board. Is there any application/procedure for this?

Thanks & Regards,

Siddartha

    Hello Siddartha,

    You would want to try the Azimuth-Range Heatmap via the mmWave Visualizer GUI. This option can be enabled under the Config Tab -> Plot Selection tick.

    Once ticked, hit "Send Config to mmwave Device".  It will ask you to keep the Frame rate below 1FPS for uart data rate reason.

    Plots area will show a new plot as below. Please zoom in as needed to see the heat map of reflections from objects near the sensor:

    Objects with stronger reflection appear brighter in the plot.

    Thank you,

    Vaibhav

    Hello Vaibhav,

    Thank you for the reply.

    Am working in Ubuntu environment. I use serial ports /dev/ttyACM0 and /devttyACM1 for configuration and data flow.
    Instead of mmwave demo visualizer (Google Chrome browser based) , I would like to access the data through the "C" program on my PC from the mmwave IWR1443 target device.

    For Example: Assume I want to access the parameter "Number of Objects detected", through the "C" program.
    Finally i am interested in accessing all the parameters which is displayed in the "Plots" section of "mmwave demo visualizer (web based).
    Can you please tell me how to proceed and step by step instructions to follow.
    (PC <=> IWR1443)

    Thank you for your help.


    Thanks,
    Siddartha

    Hi Siddartha,

    Please look at the following post which talks about accessing the detected objects structure in your own program.

    e2e.ti.com/.../607492

    The above post is about doing this on the 1642 mmw Demo but the same documentation, which explains the output data format and the corresponding structure, is available for the 1443 mmw Demo as well at C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr14xx\mmw\docs\doxygen\html.

    Regards
