Hi,

I had test two condition, Can Launch the Demo Visualizer, both results are the same - when people move, only some noise (a lot of little black point), can't detect people)

 

1.      Hardware: ES 2.0

         Firmware: mmwave_industrial_toolbox_2_3_0\labs\lab0013_traffic_monitoring_16xx\prebuilt_binaries\traffic_monitoring_16xx_lab.bin

       GUI Tool: mmwave\mmwave_industrial_toolbox_2_5_0\labs\lab0011-pplcount\lab0011_pplcount_quickstart\pplcount_gui.exe

        50m configuration: Formal release on Ti Web

   

 

2.      Hardware: ES 2.0

         Firmware: mmwave_industrial_toolbox_2_5_0\labs\lab0013_traffic_monitoring_16xx\prebuilt_binaries\traffic_monitoring_16xx_lab.bin

         GUI Tool: mmwave\mmwave_industrial_toolbox_2_5_0\labs\lab0011-pplcount\lab0011_pplcount_quickstart\pplcount_gui.exe

         50 m configuration: Formal release on Ti Web and change lowPower 0 0 to lowPower 0 1

    Hi Melvin,

    From the images you have provided, it seems you do not have enough points in the point cloud.

    We can start by changing the CFAR configuration:

    cfarCfg 4 4 15 16 8 6 0 63 63 0 1 – this is the original

    Try changing the bold values: cfarCfg 4 4 15 16 8 6 0 30 30 0 1

    This will greatly improve the amount of points in the point cloud.

    Try changing the scenery parameters as well, to allow detections in a wider field around the device: sceneryParam 1 -15 15 0.0 75.0 0 0 0 0 1 1.25 11.0 20.0 50.0 0 0 0 0

    In my testing, there seems to be a minimum range of about 3 meters for successful tracking. You can see from the screen cap below. Even though I start walking right in front of the sensor, the tracker doesn’t start tracking me until I am about three meters out:

    You can see in the picture above that there are a lot of points centered around the track - unlike the examples you have posted.  If you still cannot improve the tightness of the cluster, try changing some of the GTrack parameters to allow for a looser cluster:

    allocationParam 30 60 1.0 3 2.8 2.0  - The bolded value is the diameter of the cluster in meters - This can be increased to allow larger clusters, but in my testing I have not seen a need to do that.

    Regards,

    Justin
