    • RE: IMU Frame off

      @zauberflote1 We are using our own custom airframe. Our SDKs are 1.6.0 beta and 1.4.5. However, I also just spoke with a colleague who owns a Starling 2, and he confirmed our findings.

    • IMU Frame off

      Hello,

      According to your website, it seems like the VOXL2 coordinate frame should be FRD. However, on both of our VOXL2s with different SDKs, we get z pointing upwards (IMU telling us -9.81m/s^2).
      This holds true for voxl-inspect-imu and the rostopic imu_apps.
      Is this a bug? Are we doing something wrong? We are a little confused, as this contradicts your information on your website and in your documentation.
      The only topic that seems to be correct is imu_apps_raw. However, there is not documentation on imu_apps_raw at all and it only exists in one of our SDKs.

      Thank you.

    • RE: MSU-M0149-1 IR Filter

      Hello,
      could anyone please help me with my question? The data cannot be found in your documentation. But it can be found in your documentation for other cameras.

    • Setting up different AprilTag families

      Hi ModalAI team,

      I would like to use different AprilTag families than the old 36h11 family. How much work would it be to run a different family through the modalAI architecture over ROS packages? Ideally, I would like to change the voxl-tag-detector so it can use the custom48h12 family. How would one approach this problem?

      Thank you.

    • MSU-M0149-1 IR Filter

      I bought a MSU-M0149-1 camera. Unfortunately, the data sheet on your website is empty and the information in the store is also very limited compared to your other cameras.
      Does this camera come with an IR cut filter? Can I detect IR markers with this sensor?

      Thank you.

    • RE: voxl-camera-server behaving differently

      This worked. Thank you.

      However, one thing I still cannot find is the apriltag-server. It is listed as a requirement on the voxl-vision-hub. When I try to start the server, I am told it could not be found, and I also cannot find an apriltag-server in the other documentation pages about relocalization and apriltags.

    • voxl-camera-server behaving differently

      I ran the voxl-vision-hub for the first time, installed ROS and ran voxl-configure-mpa.
      After running those commands, the command:

      voxl-camera-server -l
      

      now only returns this:

      ====================================
      Number of cameras detected: 1
      ====================================
      

      instead of the longer information output that is shown in the documentation docs. It also causes the camera to not work in the portal anymore until I just run voxl-camera-server.

      I also found that all the servers listed underneath the voxl-vision-hub as requirements are found, except for the apriltag-server. How do i get the apriltag server running?
