IWR6843ISK-ODS: What people counting labs are available to use with IWR6843 ODS ES 2.0?

Hi Radha,

I've asked an expert to look into this and we should have an answer for you in the next few days.

Cheers,

Akash

Hi Justin,

1. 68xx ISK_ODS 3D People Counting - This demo works with the board but I'm having a hard time understanding the output through the GUI. It is not as simple as matlab and the target data persists even if there is no target in zone. Is there any live demo available or any documents regarding this on the ti website?

2. 68xx ODS - People Counting - Is there any idea to provide support for this lab? I see that precompiled binary or the source code for ods lab from ITB 4.1.0 doesn't work.

Thanks,

radha.

Hi Radha,

1. This lab has a few options in the visualizer - specifically, note that there is an option to turn visualization of static points on and off. Note that the device always uses the static points with the tracker, but these points are just not shown when the option is not selected. These static points are used to detect people who have become stationary after entering the tracking area.

2. Please try recompiling the binary.

Regards,

Justin

Hi Justin,

1. With the 3D demo, I can see that once the targets are tracked, they do not go away even when there is no one in the zone. Also the parameters in config file seems to be different than the ones in people count customization guide. Where can I find documents on how to tune the sensor for 3D demo? It will be helpful if there is any live demo video of 3D demo.

2. With the ODS demo, I tried recompiling the code imported from ITB 4.1.0 using sdk 3.3.3. I can only access UART port and no data is coming through data port. I see nothing in Matlab GUI. This is what I get while running matlab.

Thanks Justin. I'm working on 3D demo and that seems to work fine.

Thanks,
