IWR6843ISK-ODS: Regarding frame rate and output

Aleena N A

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843ISK

I am doing a project on people identification using IWR6843ISK-ODS. What is the frame rate? How does the saved output looks like? Where I can save it?

Hello

Have you had a chance to look at the User's guide in the Tirex lab/demo where the data format is listed.

The update rate is per frame and frame periodicity in the profile config sets this.

For Data format:

https://dev.ti.com/tirex/explore/node?node=AAMBDqRctFUaJ4xh6n3SbQ__VLyFKFf__LATEST (Or Navigate to Industrial Toolbox -> Labs -> People counting )

Config file: See of the files here:

For explanation of basic Chirp parameters

mmwave_sdk_user_guide.pdf ( or Get the latest from mmWave SDK page )

See section :

Thank you,

Vaibhav

I want multiple values of for a single frame. This is my data saved as csv file. My purpose is identification of people. Here there is no subframes. How to add that?

Hello Aleena,

This CSV file only saves the pointcloud and tracker data from the UART stream for each frame. This is the only output for the default project binaries for the people counting. What exactly are you referring to by subframe data? What other data are you hoping to get?

Also, the frame rate is located in the frameCfg command in the cfg file, it is set to 120ms period by default.

Jackson

I require much more data for voxelisation. Since I have only a set of values for a tracked object I am not getting accuracy for that. Referring to subframes I think,if there are subframes there will be more data. That's what I am looking for. Does it can be like that?

Hello,

It sounds like you want more data in the pointcloud so you can form some better 'image' of the object you are tracking? Please see the following document for information on increasing the pointcloud density. You will likely need to decrease the thresholds in the CFAR configuration.

Hello,

Exactly. I want more data in point cloud. Let me look at this. Thank you so much.

Thanks and Regards

Hello Sir,

I would like to know that is it possible to obtain the 3D point cloud from IWR6843ISK or IWR6843ISK-ODS??

Hello Aleena,

The pointcloud is output from both the ISK and ODS board EVMs. The performance may be slightly different as the antennas are designed for different performance.

This says about the point cloud. The output that we obtain in people trackinga nd counting is their localized information after working on point cloud. That point cloud is what I want.
