    • RE: QVIO Flight violently unstable

      @Alex-Kushleyev I have narrowed one of the main causes of instability down to my quads own frame (prop protectors) within the QVIO tacking FOV. Since I am using the AR0144 cam I modified the mask file in GIMP to include only 0 and 255 for the same aspect ratio of 1280x800 at full and 1.4 res to try to apply the mask in the qvio config file but no matter what I try it seems the mask is not affecting QVIO at all. I tired a fully blacked out mask as a test and it didn't change anything. I also ensured the header matching the format found in this post.

      Have you gotten a mask example to work with the AR0144?

      @Gary-Holmgren @Alex-Kushleyev Are you able to check this out I'm not sure what could be causing this. I had qvio working perfectly fine on this stack before.

      @Gary-Holmgren

      Not sure why these would be outputting different roll values? could it be the cause of the forward and back oscillation that happens when I put it into position mode? The vehicle was completely still and I ran these commands within 10 seconds of each other.

      I also see that voxl-inspect-pose and inspect-vio are matching but qvio is not

      also, is this something that ha to be set in PX4 relative to IMU_APPS??

    • RE: Configuring VOXL 2 with a new UDP port

      @Eric-Katzfey My apologies I guess I am confused what you mean. I tried using MAVSDK with 14550 but it wouldn't let me connect. Also, I have QGC connected using 14550 if that matters.

      @Gary-Holmgren Tried re-calibrating the tracking cam and IMU, as well as ensuring everything was rigid. Still no luck.

    • QVIO Flight violently unstable

      Hello, I am trying to debug my QVIO flight which is very unstable. When hovering the vehicle does not stay still instead it pitches back and forth aggressively. I can fly in manual mode and altitude mode without any issues at all, but when hovering in altitude mode and switching to position it immediately starts cyclically shaking back and forth and gets worse the longer I let it go.

      Its paired with the AR0144 tracking cam and has been calibrated. This is setup to also use a GPS/MAG but indoors use VIO. there is also a VL53L1X mounted for altitude sensing below 4m. Is there something that anyone would recommend checking to see what may be happening here. I followed along with the EKF2 param helpers for VIO in px4 as well.

      This is my extrinsics:

      "extrinsics": [{
      			"parent": "imu_apps",
      			"child":  "tracking",
      			"T_child_wrt_parent": [0.0237, 0.0024, -0.0073],
      			"RPY_parent_to_child":    [0, 90, 90]
      		}, {
      			"parent": "body",
      			"child":  "imu_apps",
      			"T_child_wrt_parent": [0.1138, -0.006, 0.040],
      			"RPY_parent_to_child":    [0, 0, 0]
      		}, {
      			"parent": "body",
      			"child":  "ground",
      			"T_child_wrt_parent": [0, 0, 0.0537],
      			"RPY_parent_to_child":    [0, 0, 0]
      		}]
      }
      

      and qvio-server config:

      }
      
      

      vio_cams config:

      			"cal_file":				"opencv_tracking_down_intrinsics.yml"
      		}]
      }
      
      

      And heres my qvio overlay:
      e85c7381-1f16-4171-908a-6d5cc5b3143b-image.png

      Would looking into opvenins be a solution, and can it work well with just a single tracking camera ?
