Hello Champs,
I'm writing to ask about compRangeBiasAndRxChanPhase calibration for 3D people counting demo.
1) Does compRangeBiasAndRxChanPhase calibration only support in Out-of-Box demo, not other demos?
2) Can I have calibration cfg file for 3D people counting demo?
I accquired compRangeBiasAndRxChanPhase value using Out-of-Box demo firmware, mmWave visualizer, and profile_calibration.cfg in SDK v.3.04.00.03.
The setting values was compRangeBiasAndRxChanPhase 0.0410262 -0.61984 0.15067 0.57309 0.31027 -0.21072 -0.56528 0.04568 0.49631 -0.53430 0.31598 0.44183 0.08667 -0.47607 -0.25137 0.37787 0.54703 -0.67166 0.28995 0.86420 0.34698 -0.25595 -0.96667 -0.14825 0.58847.
To get this value, I installed IWR6843ISK Rev C board on the tripod that is 1.0 meters away at a height of 50 cm from the strong metel reflector. (measureRangeBiasAndRxChanPhase 1 1.0 0.2). And this value works well with Out-of-Box demo firmware and PC GUI.
After I appied the setting value into 3D people counting demo's cfg file (ISK_6m_default.cfg) but mmWave people couting demo GUI doesn't disply point cloud as like the default setting value. (compRangeBiasAndRxChanPhase 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0). So I expect that there should be exist calibration.cfg for 3D people counting demo.
It seems that antena configuration for 3D people counting demo is different from OOB cfg file, so compRangeBiasAndRxChanPhase from OOB can't be reused in 3D people counting demo.
3D people counting demo's ant configuration
antGeometry0 0 -1 -2 -3 -2 -3 -4 -5 -4 -5 -6 -7
antGeometry1 -1 -1 -1 -1 0 0 0 0 -1 -1 -1 -1
antPhaseRot 1 1 1 1 1 1 1 1 1 1 1 1
