AWR1642BOOST: Point Cloud Data

Hedza Mafumba

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Good Day,

I have read from the internet, user guides and data sheets that the EVMs generate point cloud data of the detected objects. My questions:

How do the devices generate the point cloud data?
How does the point cloud generation algorithm track a list of the detected objects? For example, an object may be detected in the first frame and given an index (i.e detected point 1 or 2), then the same target is missed in the second frame, then detected again in the third frame and still given the same index.
In which function does point cloud generation occur, MSS or DSS?

Thank you

Hello,

1. Please go over the training material and mmw demo doxygen document.

https://training.ti.com/mmwave-training-series

C:\ti\mmwave_sdk_03_03_00_03\packages\ti\demo\xwr16xx\mmw\docs\doxygen\html\index.html

2. Refer documents (pdf and doxygen) in SDK

C:\ti\mmwave_sdk_03_03_00_03\packages\ti\alg\gtrack\docs\

3. All the major processing and point cloud generation are done at DSS end.

Regards,

Jitendra

Hello,

My question is still on Question 1:

How do the devices generate the point cloud data?

In your response, you referred me to the TI training videos, but my query is not about how the radar detects and measures the range or the doppler of an object. My question assumes that an object has been detected by the radar, so how does the AWR1642 generate the point clouds for that target? because if you take a human, for example, there are many detected points on that person. So how does it partition or come up with a number of detected points on an object?

Hi,

In mmw demo after detection the objects in the scene it does the clustering and tracking which further generates the cloud point. While clustering/tracking it combines nearby object points which might be reflected from single object.

mmWave SDK provides application's process information in detail to the doxygen documents, I would suggest you go over those. Additionally you can refer this FAQ page which will help your future query related to mmwave SDK.
