IWR6843ISK: Detecting Static Object

Odera Dim

Part Number: IWR6843ISK

Hi,

I have a simple parser that allows me to view the X, Y and Z position from the 3D_TARGET_LIST TLV type (I am working with the LRPD Demo). I can also visualize a point that appears to be objects in the scene. The issue is I would like to apply a configuration to the sensor that would allow me view only the static objects in the scene. An even better outcome will be to have a config that allows me visualize purely static object and another that allows me visualize only dynamic objects in the scene.

Thanks

Hello.

I would recommend that you use the Area Scanner demo as it has additional processing to detect static objects.

Hope this helps,

Santosh

Hi and thanks for your suggestion. However, I will please like to know how I can determine the range FFT size. My assumption is that it is supplied in the configuration file. I don't know which command on the configuration file supplies this to the sensor at run time. I also need this value in order to correctly read the content of the TLV file. Thanks.

Hello. I am looking into some internal documentation regarding configuration commands and will get back to you as soon as possible.

Sincerely,

Santosh

Hello.

The range FFT size is the nearest power of 2 to the number of ADCsamples defined in the profile configuration(so if you have 50 ADC samples the range fft size will be 64). The profileCfg command can be found in the configuration file and documentation on it can be found in the SDK user guide. The range processing unit also calculates this FFT so it also impacts the range FFT size. The documentation on rangeproc can be found in the sdk under sdk_install/packages/ti/datapath/dpu/rangeproc/docs/doxygen/html/index.html.

Sincerely,

Santosh
