MMWCAS-DSP-EVM: RADAR SDK - Cascade Object Detection sample usecase

Part Number: MMWCAS-DSP-EVM
Other Parts Discussed in Thread: MMWCAS-RF-EVM, IWR6843ISK, AWR2243

Hello,

I have been experimenting with real time object detection using the MMWCAS-DSP-EVM board paired with an MMWCAS-RF-EVM (rev D) board running the Cascade Object Detection sample usecase found in the RADAR SDK (v3.08.0).

I have run the calibration using a corner reflector and generated the calib_coef.bin with the MATLAB script (vision_sdk/apps/src/rtos/radar/src/usecases/cascade_radar_object_detect/create_calib_coefs.m) and am using the default 'radar_test_vector' folder found at (vision_sdk/apps/src/rtos/radar/src/usecases/cascade_radar_object_detect/radar_test_vector).

I've attempted to collect sample point cloud data of a person walking in front of the sensor, however the point cloud does not appear to represent that and instead seems to mainly captured a large number of points a 0 or < 50cm away from the sensor, which can be roughly seen in the below plot of a single captured frame.

Compared to the point cloud frame captured from an IWR6843ISK running the "68xx ISK - People Counting" Lab

Where we can see a point cloud corresponding to a person. I was expecting the sample use case on the MMWCAS-DSP-EVM to output a similar point cloud and would appreciate any guidance on whether this use case would actually be expected to track a person, and if so if there is any advice you can offer on configuring the Cascade radar system to do so.

Thank you,

Robert

    Hi,

    We recommend that you capture the raw data and post process with provided matlab scripts. The real time demo has limited support

    Did you port yourself the vision sdk demo to awr2243? It is no longer supported out of the box.

    We have provided in the Cascade mmWave FAQ some patches from the community to update the demo for vision sdk 3.8. However our support team has limited knowledge on this demo and the developers who worked on the demo are no longer available.

    thank you

    Hi Cesar,

    Thanks for getting back so quickly. I'll try post processing some raw data, would the best scripts to use be the ones provided with MMWAVE Studio?

    I had previously followed the FAQs to patch the vision SDK to support the AWR2243 to hopefully everything is built correctly. Will future versions of the Vision / Radar SDK support the AWR2243 or is there a new supported method for developing sample applications using the RF and DSP evaluation boards?

    Thanks,

    Robert

    Hi Robert,

    Yes, the only scripts provided at this point are included in the mmWave SDK. These are matlab scripts that can be modified as desired.

    As far as I understand there are no future plans to for the Radar SDK to support AWR2243. Customers would need to develop their own applications

    thank you
