IWR6843ISK-ODS: quantity of point clouds

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843ISK

Recently, I'm using IWR6843ISK-ODS doing human behavior research but the point clouds cannot represent a person clearly. My example shown as follow:

Recently, I saw yours "Intelligent Fall Detection" example which demonstrated by IWR6843ISK could display quite complete person. The example shown as follow:

The point clouds collect by IWR6843ISK are very clear but the point clouds which collected by ODS in my test are not so clear. Is it possible that IWR6843ISK-ODS reach same effect as IWR6843ISK?

    Hello,

    There are several different ways you may be able to increase the pointcloud density. You can reduce the CFAR thresholds as a best place to start. You can modify the chirp profile to decrease the range resolution. You also might try changing the mounting height of the sensor, as it might be necessary to get a better view of the legs and feet.

    Also, I assume you are using the wall mounted 3D people counting lab? You can try using the overhead mount lab (but still mount the sensor on the wall, just change the sensorPosition and boundaryBox commands in the CFG file to match). This uses a different detection chain that may give a better point cloud response with the ODS antenna.

    For more information please see the following document.
