IWR6843AOPEVM: 3d people tracking help

Adib Jalal said:

1 - Is there a way stop and start the sensor?  OR do we just close the visualizer and relaunch?

Closing and relaunching is the best way. You can modify the demo and the visualizer if you want to support this functionality, but it does not exist by default.

Adib Jalal said:

2 - What do the different colors around the tracking box mean?

In the Industrial Visualizer, they indicate different tracks.

Adib Jalal said:

3 - Can I customize my scene size?  (By default I see Y=8m and X=+/-4m and z=3m)

In the industrial visualizer yes, simply change the boundary box parameters.

Best,

Nate

When I change the boundary box parameters do I use start and send config or start without config?  Can I change dynamically any parameters while it is running?  I am also seeing it hang and not track correctly in the space.

Is there a min and max angle that we need to be for detection if mounted from a wall?

Hi.

So I ran several tests and sometimes I am seeing the individual disappear when still or lying down.  Also, I am seeing some false additional detections.  Attached is one of those tests.  Here is a description of the test.  Sometimes it tests and I see the problems that I described above.  Please advise.

Thanks.

Here is the sequence for the test I am doing.

1 - Walk into room and stand still.
2 - Walk to the right and sit on sofa.
3 - Lay down on sofa.
4 - Stand and walk back to entrance of room and sit on floor.
5 - Lay down on the floor.
6 - Stand and walk to sofa nearest the sensor and sit.
7 - Lay down on that sofa.
8 - Stand and exit the room.
Settings: Sensor height = 2m, 15 degrees angle, placement corner of room, Room Y = 4.5m, Room X = 4m, Z = 3m.

Hi,

I don't see the video, it doesn't render in the dialogue. Can you try using a configuration file with static retention enabled?

Best,

Nate

It is a quicktime video that you may need to download.

Hi,

Please attach the video in a supported format.

Best,

Nate

What are the supported formats?

MP4 should work. Just make sure that you are able to see the video once it's posted.

Best,

Nate

Please see the attached.  Please let me know if you are able to open.  Thanks. - Adib

Hi,

Are you using a configuration file that uses static retention (it should have the fineMotionCfg line in it). If not, please use one that does.

Best,

Nate

I am using the default config file AOP_6m_default.cfg.

I do not see the fineMotionCfd line in it.

Hi,  I found the static retention cfg.  Reran the tests.  I am attaching two more tests that I ran.  Test script is still the same as above. Only 1 person.  I am still seeing a lot of false squares and in a few instances it is losing the person when still sitting or lying.  Any suggestions.  Thanks.Library-Test2-Day2-standing-sitting-layingdown-E15degH2mY3mX4mZ3m-staticRetention.m4vLibrary-Test1-Day2-standing-sitting-layingdown-E15degH2mY3mX4mZ3m-staticRetention.m4v
