  • Fixed frame pose MPA to ROS
    J jay.miller

    This is essentially bumping Apriltag landing fixed frame ROS interface, How can I see the apriltag offset in ROS, and How can I get fixed pose via qgc or ros topics.

    I can perform apriltag relocalization and see that it is working correctly via voxl-vision-px4 -p or other voxl means, but both /mavros/local_position/pose and /qvio/pose report position in local frame. I understand that I can issue commands in fixed frame to then be corrected by mavros en route the PX4, but this is only useful in ROS/QGC if my fixed and local frames are roughly equivalent (so using relocalization to correct for drift, but not to initialize position).

    Thanks!

    For reference, my platform is an m500 with VOXL1:
    Firmware: 1.13.2, Custom Fw. Ver. 0.1.1
    system-image: 4.0.0
    kernel: #1 (closed) SMP PREEMPT Thu Oct 13 17:57:05 UTC 2022 3.18.71-perf
    hw version: VOXL
    voxl-suite: 0.9.4

    and my parameter file is:
