IWR6843AOP: What has been improved in Overhead 3D People Counting?

Hello,

1. The overhead people counting demo in toolbox 4.6.0 uses an improved tracker, version 0.112, from the following directory in Industrial Toolbox. Compared to this, the people counting demo in toolbox 4.5.1 uses tracker version 0.110 which is included in MMWAVE-SDK SDK 3.5.0.4.

C:\ti\mmwave_industrial_toolbox_4_6_0\labs\common\src\dpu\trackerproc_overhead\packages\ti\alg\gtrack

Please note that the updated tracker passes the performance regression tests used in the previous version so any existing performance achieved with the previous demo will not be impacted. You can refer to the tracker version history in the following file to look at the detailed change log.

2. Besides the tracker improvements, the new demo also supports a low bandwidth mode for FCC compliance as mentioned in the demo release notes. Please refer to the overhead people counting demo user guide in toolbox 4.6.0 for more details on this feature. There is a new CFAR function added to the detection chain in the following file. 

C:\ti\mmwave_industrial_toolbox_4_6_0\labs\common\src\dpu\capon3d_overhead\modules\detection\CFAR\src\RADARDEMO_detectionCFAR_priv.c

This mode is used only if the demo is built for low bandwidth mode as enabled by the compile time flag "CEILING_MOUNT_CFAR_LOW_BW".

You can compare this file with the previous demo if needed.

Thanks
