AWR1642BOOST: People counting demo UART output

CCS/IWR6843ISK-ODS: How to analyze. DAT files exported from IWR6843

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: MMWAVEICBOOST,

Tool/software: Code Composer Studio

hi!

I am using IWR6843ISK-ODS+MMWAVEICBOOST to detect objects and develeop on it,there is some questions for out-of-box demo:

1、I want to export 3D point cloud data and restore the three-dimensional model of objects,
and export a dat file from mmWave_Demo_Visualizer. Do I want to ask if the dat file contains 3D point cloud data? How to analyze? I use PCL library to reconstruct three-dimensional point clouds,

2、I export the dat file from out-of-box DEMO, and the analysis shows that the following data is a complete PACKAGE:

0201 0403 0605 0807 0600 0003 8000 0000

43680a00 2C01 0000 c88f 6848 0200 0000

0300 0000 0000 0000 0100 0000 2000 0000

2c07 983d 0000 0000 2ada e3bd 0000 0000

Ed07 a83d f7c8 933d 54e1 783d 0000 000

0700 0000 0800 0000 BF00 7802 BF00 7802

0600 0000 1800 0000 0A 0b 0000 8805 0000

60b8 0000 0000 0000 0000 0000 0000 0400 0000

According to the structure description of the derived data, the X coordinate is 933d, which is 2 bytes. Is it directly converted from hexadecimal to 10-decimal, and get the X coordinate?

3、Another problem is that if we detect a static object, no matter how we change the position, we can't see the change of object coordinates in DEMO.

    Hello,

    1. The dat file contains the exact output byte stream of the device. Therefore if you have enabled a 3D cfg and can see a 3D scatter plot when you are recording the data then the .dat file will have the 3D scatter plot data.

    2. Please refer to the source code of the GUI for the Area Scanner lab for an example on how to parse the data in the dat file.

    3. You should see the object location change in the 3D scatter plot. If you can not see this then the SNR of the object may not be sufficient to detect with your current settings. Change the settings or to make sure you have everything setup correctly test with a highly reflective static metal object.

    If I use IWR6834ISK-ODS to detect the box, I need to get the 3D point cloud data of the whole box surface shape, but at present I can only get some scattered 3D point cloud data. I can not reconstruct the 3D model of the box based on these 3D point cloud data. What is the solution?

    Maybe I'm not quite sure. I want to use TI mmWave chip to do 3D imaging like Laser radar.
