IWR6843ISK: Tracking parameter for maintenance

JINHYEONG LEE

Part Number: IWR6843ISK

I have read the documentation on tracking algorithms.

I would like to adjust the maintenance parameters of the tracked object.

For example, if the number of new point clouds connected is less than 3 for the tracked object, I would like to free.

However, as far as I know, the only parameter related to maintenance is the state parameter, which changes the state by HIT or MISS event, and HIT event can be occur even with one point cloud is connected with tracked object.

In other words, I want to increase the HIT event occurrence condition.

Are there any parameters for this? Or do I need to change the code?

Thanks.

Hello,

You can also change the allocationparam fields. This will change which points in the pointcloud can be allocated into a specific track. Updating the tracker code can be done, but there is opportunity to decrease performance in other areas when making small updates like this. Please see the documentation for allocationParams in the following E2E post.

Thank you for reply.

I'm not asking about the allocation of a new track (allocationParam), but about the maintenance of the instance being tracked.

And I think that the maintenance parameter is thought to be the state parameter.

The status of the tracking instance changes based on HIT and MISS events.

Is that correct?

If correct, to make maintenance more demanding, I want to change from ACTIVE state to FREE state if the number of points newly connected to the tracking instance is less than 3.

Are there any parameters for this? Or do I need to change the code?

Thanks.

P.s. The documents in the link are very good for me.

Hello,

You are correct you should be using the state params. These will be the main parameters for determining the maintenance of the tracks.

You can also use the gatingParams to change which points remain associated with each active track. But beyond the parameters listed in the above documents, there are no other parameters to change the tracking behavior directly.
