IWR6843: People tracking and counting

Hello,

I want the point cloud data before group tracking(point cloud data from DSP) for processing in people tracking and counting implementation. Is it possible? From where should I obtain ths?

Thanks in advance

Thanks and regards

Hello Aleena,

The pointcloud output is not modified by the tracker, so this should already be output on the UART line. The tracker uses this as inputs but does not modify the pointcloud data. Please see the below document for info on the 3D people counting demo.

Hello Jackson,

So, from where we can obtain that data?

Thanks and regards,

Aleena,

Please see section 9 of the document I linked above for information on the pointcloud output structure over UART. The pointcloud information will be transferred on the UART lines every frame.

Jackson

Hello Jackson,

I have obtained that data. It contains frame and track id and its corresponding x,y,z,vx,vy.vz,ax,ay,az. But I want data before this. I want the output of DSP.

Thanks and Regards

Hi Aleena,

The pointcloud TLV is also output from the sensor. Above you referred to the target TLV, but there is a similar one for pointcloud, which is the output from the DSP processing. If you look at section 9.1.1.3, it details the pointcloud TLV structure. This is TLV type 6 and is parsed by the visualizers. This is reported in spherical coordinates.

Regards,

Jackson
