IWR6843: Identifying human counts in the UART output data

Hi Samidha,

I would recommend you take a look through the docs located in the people counting labs area, specifically <mmWave Industrial Toolbox>/labs/People_Counting/docs as these give quite a lot of detail on how this labs function. In regards to your specific question, the number of targets is the number of tracks created by our tracking algorithm. These are clusters of points that are close enough together to be considered a singular group, or _track_. The allocation of these _tracks_ is configurable, as those documents will explain, to support larger and smaller targets. These could range from something like a small animal to a large vehicle. For most of our demos, the tuning used in the provided .cfg files is targeted at human-size tracks. So out of the box, the numberOfTargets will likely be the number of people that it thinks are in an area, but you may need to tune this based on your use case. For example, if you are using overhead 3D People Counting, the height that the sensor is from the ground would affect the size and strength of the point clouds used to make the tracks, so you may need to adjust the thresholds. So to summarize, you can use the numberOfTargets to estimate how many people are in the area covered by the radar, but be prepared to perform some tuning in order to get the results you are looking for in your specific usecase.

Best Regards,
