Synchronize multiple Azure Kinect DK devices

盈憲陳 1

I need to connect 2 different Azure Kinect sensors to one PC for capturing videos from different angles at the same time, and I want to use python control them.

Do you have any code for reference?

thanks.

@盈憲陳 Welcome to Microsoft Q&A forum!

I need to connect 2 different Azure Kinect sensors to one PC for capturing videos from different angles at the same time, and I want to use python control them.

Yes, you can connect multiple Azure Kinect Sensors. Each Azure Kinect DK device includes 3.5-mm synchronization ports (Sync in and Sync out) that you can use to link multiple devices together. After you connect the devices, your software can coordinate the trigger timing between them.

Please check the documentation for more details Synchronize multiple Azure Kinect DK devices incase if you haven't checked earlier.

Do you have any code for reference?

For information about how to set up your software to control the cameras and use the image data, see the Azure Kinect Sensor SDK.

Also, There are few samples available here

Hope this helps. Do let us know if you have any further queries. Happy to assist you further.

Thanks for your help!
Now, I can sync two cameras and use k4aviewer to watch it, and also can record the video, but python's code can't work, when I search for solve the problem, I see someone have the same problem with me, the code writer also responds under the problem, but he says he will check the code, not solve the problem, so I still can't solve the problem.
Is there any other code can offer to me to try?

@盈憲陳 Below is the response from our team on this query.

There is a Python wrapper in the GitHub repository that one could use to synchronize cameras and capture data. They can refer to this example for capturing data through this interface and setting the EWiredSyncMode to either MASTER or SUBORDINATE as appropriate for their camera set up.

As mentioned earlier, This page provides an overview on synchronizing Azure Kinect DK cameras: Synchronize multiple Azure Kinect DK devices

Do let us know if that answers your query or have any further queries.
