Compiler/AWR1642: How to setting or modify G-tracking source code ? ( Radar module Placement from Horizontal to Vertical)

Agate
Expert 1275 points

Part Number: AWR1642
Other Parts Discussed in Thread: IWR1642BOOST

Tool/software: TI C/C++ Compiler

Dear TI 

Because our new customer have a n application focus on vertical than horizontal and we check hardware FOV . If we direct rotate module the FOV coverage is ok.
But  the software part we don't know how to modify can help ? ( we means the G-tracking grouping is from horizontal FOV  to vertical FOV  )


Best Regards

    Hi,

    We have to check if this is possible with algorithm developer  and get back to you

    Thank you

    Hi,

    The algorithm developer has following feedback:

    I suggest to avoid changing tracker coordinates, and let it work as is. In general, tracker is unaware of physical sensor position, and will track the target and report coordinates in sensor-centric Cartesian space.

    The only thing the one may need to do is to rotate the boundary boxes. You can either do it inside tracker library, or (even better) outside. As an example, one can see the way I rotated the boxes for ceiling mount case. (see mmwave Industrial Toolbox)

    For visualization /post-processing purposes, the output of the tracker can be rotated to match the physical reality.

    Thank you

    Dear TI

                  The only thing is to rotate the boundary boxes , Can you provide detail about this setting ?

                  Give an example seting for users is better .

    Hi,

    Can you please let me know which demo you are working on. Is this people counting?

    than you

    Dear TI 

                     It's people counting application our customer focus on vertical to replace horizontal . If only rotation it's great . 

                     But how to setting related parameters . Can share ?

    BR

    Hi,

    I will assign this thread to the team responsible for the people counting demo

    thank you

    Hi Agate,

    The IWR1642BOOST antenna only can determine angle in the horizontal plane - there is no way to get around this by changing software. After rotating 90 degrees, (as you have done for the customer) you will have angle differentiation in the elevation plane, but all objects will appear at the same horizontal position.

    Regards,

    Justin

    Dear Justin

                        The G-tracking is need modify for this rotation ?

    Hi Toyota,

    The IWR1642BOOST EVM antenna does not support angle information in the elevation axis. If you rotate 90 degrees, you no longer have information on the position of detected people in the azimuth (X, left, right) axis.

    Regards,

    Justin

    Dear Justin 

                             Our end customer have a idea for 3D people counting  with 2 radar module .  One is for horizontal another is  for vertical . 

                             If use this rotation method is ok  , we can push 2 radar module solution  to  high end market  . 

                             Radar is expensive than PIR , So radar users  almost  don't care money but care performance .

                             TI one module performance just meet  rare user only now .  Maybe 2 module solution  is a  good solution for application.

    Hello

    Based on your understanding one device is targeted for Horizontal angle and the other for vertical resolution.

    The the data from both devices would have to be fed to one device for combined tracking.
