IWR1642BOOST: Are there any tips/tricks to combining multiple IWR1642BOOST boards to extend FOV in a people counting/tracking application?

We are looking into using two IWR1642BOOST boards concurrently in a people counting application to extend the horizontal field of view to 180 degrees. Are there any demo examples or documents guiding this kind of use-case?

Thanks

    Hi Ruben,

    We haven't tried to do this before - however, if I were to do this, I would choose one of two options:

    1. Modify the gui to accept the data from both devices.  You should see the 'Data Formats' section in the user's guide.  People will be detected by both EVMs in the area where they overlap - you should be able to resolve this in the GUI.  You can also remove the overlap by positioning the EVMs so there is no overlap or using scenery parameters to remove the overlap area from one device.
    2. Feed point cloud information from both devices into one instance of the GTrack algorithm.  This will be more difficult than solution 1, however, objects will be tracked better across the whole FOV and there will be no issue with detecting people twice.

    For a demo, I would recommend option 1.  For production software, it may be useful to look into option 2, though option 2 will take significant effort to implement.

    Regards,

    Justin
