IWR6843AOPEVM: IWR6843AOP: Area scanner demo: Sometimes static objects that are not in the area are detected

Hello

I am using the IWR6843AOP to evaluate the Area Scanner

There are no static objects in the area,

but the Static Point Cloud appears in the Area Scanner.
I want to prevent objects that do not exist from being displayed in the Area Scanner.
What should i do?

BestRegards

    Hello,

    The Area Scanner demo uses the first few frames to determine the scene. Any objects that appear afterwards that are not moving are determined static. For example, a person has moved a large box into the scene and left it there. The box should now appear as static. 

    In your case, it seems that some static points show up. To they appear to match anything in the scene? Can you provide some data or videos to explain what is going on?

    There are also multiple parameters available for you to change should you continue running into issues. Read about the heatmapGenCfg and staticDetectionCfg commands and the parameters you can change in this file: /labs/area_scanner/68xx_area_scanner/chirp_configs/cli_commands.pdf 

    I would suggest first adjusting the parameter "heatmapDiffT". If the point is always in the same range, you could ignore by adjusting parameter "minRangeBin" or "maxRangeBin"

    There are multiple variables for you to experiment with.
