AWR1843AOPEVM: Synchronizing USB Camera and AWR1843AOP Radar Data via DCA1000 (ROS Support?)

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: DCA1000EVM, AWR1843AOP

Tool/software:

Hi,

I’m working on synchronizing data captured from a USB camera with raw mmWave radar data acquired from the AWR1843AOP using the DCA1000EVM over Ethernet.

My goal is to achieve synchronization with a maximum timing error of 50 ms. Both the radar and the camera operate at 20 FPS.

Are there any recommended methods or best practices for achieving such synchronization between the radar and camera data streams?

I’ve seen some research articles mention using ROS (Robot Operating System) for synchronized radar and camera data acquisition and visualization. Is there an official or supported TI ROS package that allows capturing synchronized raw radar data from the DCA1000 along with camera input?

Any guidance or suggestions on this would be greatly appreciated.

Best regards,

    Hi,

    It will be difficult to synchronize the raw data with the camera because we don't have frame level control when we capture the raw data with DCA1000 kit.

    Please give us some time to check with extended team

    thank you

    Hi Cesar,
    Thanks for your response.

    To clarify and emphasize my intent: my main focus is to identify the most accurate method for synchronizing radar and camera data. If no alternative solution offers better reliability, I’m particularly interested in developing the data acquisition system within the ROS framework.

    If any ROS-compatible tools, packages, or best practices exist—especially for handling raw radar data from the DCA1000 alongside camera input—I’d really appreciate your guidance.

    Best regards,
    Ali

    Hello,

    This has been done before on Matlab. There is a matlab package available that supports connection to the USB and it was used to synchronize with data coming from the 2944. But, this was not done will connected to the DCA1000 which decreases frame level control.

    This is a good starting point for a GUI method. Regarding ROS I am not familiar with supported packages for this.

    Best,
