IWRL6432AOP: TrueGroundSpeed Configuration

Part Number: IWRL6432AOP

Tool/software:

Hi Team,

I would like to customize the .cfg parameters of the True Ground Speed Demo for my purposes. As a starting point, I am using the .cfg profile of conveyorbelt_belt_true_ground_speed from the SDK directory.

In the first step, I want to adjust the parameters for my test environment, such as Field of View, rangeSel, SensorPosition (and possibly others?).

Question 1: The sketch from the Resource Explorer for both demos is identical in terms of the angle (Sensor Elevation). Why is 45° assumed in one case and 0° in the other, even though the position of the sensor is identical according to the sketch? 0° would mean that the sensor is attached at the end of the conveyor belt and "looks" into the travel axis of the conveyor belt.

Question 2: In the default setting, the parameter "presenceInfo" in guiMonitor is set to "enabled". I tried to add the parameter "mpdBoundaryBox 1 -1 1 0 1 0 1" in this context, but it doesn't work.

Question 3: Which other parameters should I consider to accommodate my desired application? Currently, the Industrial Visualizer only responds at higher conveyor belt speeds. Is calibration with a Corner Reflector necessary? So far, I haven't entered any correction values for "compRangeBiasAndRxChanPhase".

Thank you very much in advance and best regards

    0 degrees refers to the angle with respect to the sensor, while 45 degrees is the mounting angle of the sensor for the setup.

    Both diagrams say 0 degrees, but I mention 45 degrees because some trigonometry is done in the source code to convert from this angle to the real world angle as the pointcloud data is with respect to the sensor as opposed to the vehicle.

    This demo is based off the mmw_demo, which does not have default support for presenceInfo or mpdBoundaryBox, which are commands/parameters used in the motion and presence demo.

    I would recommend you play with the chirp timing and design parameters using the mmWave Sensing Estimator.  I don't think you need to do any calibration with a corner reflector, but you may want to maybe try improving your velocity resolution.
