    Hello,
    I have a question about VIO.

    In the PX4 documentation about VIO, it states that it is possible to recalibrate the VIO to use a stereo camera instead of the tracking camera if used purely as an indoor application.

    However, I am not able to find a documentation about setting this up to be used on the Seeker.

    Is is possible to enable both the tracking camera and a stereo camera to be used for VIO indoor flights for better GPS denied indoor positioning?

    Thank you in advance.

      I’m not sure if my post was overlooked or not, but could someone please help me out with this?
      How can I recalibrate one of the stereo cameras to be used for VIO, solely for indoor flights?

        You can change the QVIO server to use a stereo camera if you want in the front, but these are much narrower FOV.

        https://docs.modalai.com/configure-extrinsics/ would need to be adjusted to accommodate any camera location changes as well. This is not something supported out of the box with the current VOXL software and would require some work on your part to make it fit your platform and camera configuration.
