CCS/IWR1642BOOST: When a people is lying on the floor, sometimes the count became 2, not 1, and sometimes there was no detected object.

Part Number: IWR1642BOOST

Tool/software: Code Composer Studio

Hello TI,

Here are questions about lab0011 people counting/tracking demo of mmwave_industrial_toolbox_2_5_2.

When a people is lying on the floor, sometimes the count became 2, not 1, and sometimes there was no detected object. 

How can we understand the result?

 In my application, i need to detect Very fine motion 

 lab0011 people counting/tracking demo configuration file is diff(config file generated from Demo visualizer), How to modify the configuration file for High Accuracy and Velocity resolution for my application 

Thanks,

Rahul

  • Hi Rahul,

    Please see our tuning guide for people counting. It describes steps to tune the demo when experiencing this issue.

    Hello Justin,

    I already try to tune, using Tuning guide mention parameter
    you have any specific process for it or any other reference



    Thanks,

    Hello Rahul,

    The people counting demo leverage static clutter removal to ignore reflections caused by the furniture and ground. When a person is laying on the ground and not moving they are not likely to have enough motion to generate detection points.

    Can you confirm this by seeing if the person laying on the ground generates the black detection points in the point cloud plot?

    If there are no detection points then modifying group tracker parameters would not improve your detection. Instead you will need to create a chirp configuration with higher sensitivity to doppler so that even the breathing motion of someone laying on the ground can be detected.

    Another simple thing to check is to make sure that the person laying on the ground is within the radar field of view. Note that elevation FOV is +/-15 so depending on how you are orienting the EVM the ground may not be in the FOV.
