AWR1642: unit for the dim of GTRACK_targetDesc Struct

Part Number: AWR1642

There is gtrack utility in AWR1642 SDK. After run gtrack_step can get the tracked target list with GTRACK_targetDesc struct. there is a dim array in this struct and it describe it is Estimated target dimensions: depth, width, [height], doppler. . What is the unit for the depth, width ? meter? it is strange that the dimension I test seems much wider than the tracked target ( with point group), what is the definition and unit for the dim ? thanks.

    Hi,

    I checked following documentation. I don't see dim array.

    file:///C:/ti/mmwave_sdk_02_01_00_04/packages/ti/alg/gtrack/docs/doxygen/html/struct_g_t_r_a_c_k__target_desc.html#details

    This algorithm is used in the People Counting Demo available in Industrial Toolbox.

    You can probably find more information about the use of the algorithm and the units in the User Guide of the Demo

    Thank you

    Hi Chianan,

    The unit is meter. If the dim seems too big, then most likely the algo is associating points with the object that should be associated. Please lower the gating parameters to fix this.
