CCS/IWR6843ISK: IWR6843 - Want to save the plotting points in a file.

Hi Justin,

I did follow your instructions and got this in the file.

Please tell me how to derive meaning out of it.

Hi Justin,

Thanks for your reply. I managed to install MATLAB and open the main_pplcount_viz.m  file , I see another file setup.m  , Please  tell me the procedure to build the Exe from the .m files. If you have any document  stating the steps to build please tell. I need the steps to generate the print-gui.exe.

I am using deploytool for building the exe.

Hi Deepanjan,

You do not need to compile to run the gui in Matlab. If you want to read the fHistRT file, you can just open it with Matlab, and scan through its contents.

If you are trying to compile for some other reason, you should find the Matlab documentation for compiling applications.

Regards,

Justin

Hi,

I  could compile the GUI using matlab  and create the new gui.exe 

targetStruct = struct(...
'tid', {'uint32', 4}, ... % Track ID
'posX', {'float', 4}, ... % Target position in X dimension, m
'posY', {'float', 4}, ... % Target position in Y dimension, m
'velX', {'float', 4}, ... % Target velocity in X dimension, m/s
'velY', {'float', 4}, ... % Target velocity in Y dimension, m/s
'accX', {'float', 4}, ... % Target acceleration in X dimension, m/s2
'accY', {'float', 4}, ... % Target acceleration in Y dimension, m/s
'EC', {'float', 9*4}, ... % Tracking error covariance matrix, [3x3], in range/angle/doppler coordinates
'G', {'float', 4}); % Gating function gain

Is this the structure for getting the plotting of persons ?  

Hi Deepanjan,

Yes, we use PosX and PosY to plot the X and Y locations.  

Regards,

Justin

Hi Justin,

Thanks a lot for your clarification. It helped me a lot to reach my destination, yet I have couple of  questions which will help me to nail my problem.

(1)  I see the structure 

targetStruct = struct(...
'tid', {'uint32', 4}, ... % Track ID
'posX', {'float', 4}, ... % Target position in X dimension, m
'posY', {'float', 4}, ... % Target position in Y dimension, m
'velX', {'float', 4}, ... % Target velocity in X dimension, m/s
'velY', {'float', 4}, ... % Target velocity in Y dimension, m/s
'accX', {'float', 4}, ... % Target acceleration in X dimension, m/s2
'accY', {'float', 4}, ... % Target acceleration in Y dimension, m/s
'EC', {'float', 9*4}, ... % Tracking error covariance matrix, [3x3], in range/angle/doppler coordinates
'G', {'float', 4}); % Gating function gain

but cannot get hold of the posX,posY  so that I can write it on my file for my project to use it.

(2)  I got into the fHistRt.mat  file and opened the point cloud  tab and saw 

2.0462201     4.3136530     4.3136530      4.3136530
-0.91629785 -0.88357294   -0.85084802   -0.81812310
0.077521712 0.077521712  0.077521712   0.077521712
8.1657124    10.908037       11.011115       7.8436275

Please tell the headers for it.

(3) In target list structure tab I get  

(1) Numtargets  - I hope this is the number of people count.

(2) TID - The IDs, like 1,2,3 depending on the number of people.

(3) S - Could not understand  got values like  

0.966949999332428 0.0743650645017624
3.49675631523132 0.802237391471863
0 0.198953077197075
0 -0.135047361254692
0 0.410013854503632
0 -0.248371139168739

(4) G - Could not understand (4,4)

Hi  Justin,

Thanks for your detailed explanation. I could get the coordinates from the MATLAB code. Is there any documentation where we can tap the data from the Sensor without the GUI ? 

Another thing is that  we want to run 3 sensors to run on a single PC.  Do we have any application which supports multiple  MMwave sensors ?
