Hello.

This is a new starling 2 drone. I am trying to calibrate the cameras, but it seems difficult. When chess board is placed inside rectangle, the rectangles doesn't fill most times, sometimes, i get detections, sometimes i don't. It took several minutes to get a 40% collection rate. Is the calibration supposed to be this difficult? or is there a technique to this? I have seen the video on the documentation website for this, and it was seamlessly easy. Please let me know if I am doing it wrongly?

Expecting your response soon. Thanks.

Hello Support,

Can anyone kindly look into this please?

I tried it accessing the cameras today from the voxl portal, it showed live footage at first, then it crashed. Can you kindly assist.

Thanks

@Alex-Kushleyev Thank you for your response. Sorry I have been away for exams. I took the drone outside to be sure it was not because of lightning. After refocusing the tracking front camera lens, i realized that when the checkerboard was moved to the sides, and also towards the top and bottom of the camera, the images were sharp, but when it was moved directly in front of the camera, it became blurry. I inspected the Lens physically and cant seem to find any damage. I have attached the images so that you can better grasp what I mean. Thanks.

HI, I am trying to calibrate my starling 2 drone cameras, but I realized I cant access my cameras from the voxl-portal. On voxl portal, I can see the list of camera pipes, but if I select any one if them, I dont get a footage. I have attached screenshots to make you understand what I mean better. I dont know mcuh about this, could you please point me in the right direction? How can I get it working


Hi modal AI support,

I am trying to calibrate my starling 2 drone camera using openCV 6x8 chessboard (I used this command " voxl-calibrate-camera tracking_front -f -s 6x8 -l 0.038". I think my camera lens might be dull, I have a starling 2 Lens Focus Tool, but I can't find any resource to help me adjust the focus. I have attached an image of me me trying to calibrate the camera so that you clearly understand what I am trying to say. From the first image, you can see how blurry the chessboard is, In the second image, you can see that the chessboard is barely showing when the chessboard was moved inside the rectangle. The third image are what I saw in the starling 2 Lens Focus Tool.

Kindly assist.

Thanks,
Taiwo

Hi support,

I am a PhD student, and I am very new to robotics. We have 4 starling 2 drones in the lab, and right now, I have two of those drones being prepared for RMA. The drones keeps getting damaged because I don't have the right knowledge about drones. I looked up the technical documentations online, but there are still so many things I don't know. For instance, one of my drone crashed when i toggled the switch to hold mode (and it hasn't done that ever since I got it),it shot straight up very fast. I keep getting height estimate not stable (I don't even know what to do to fix that error). Also, the last working drone also drifts around when you toggle the controller to hold (the middle position). At this point, I cant even fly the drones because I might crash them again. And eventually I will get in trouble with these. Can you help with documentations that will make a beginner get all the necessary knowledge. Right now, I am just working on the drone blindly. I will be grateful if you can help with the situation.

Thanks,
Taiwo

@Eric-Katzfey No, the propellers are well positioned (that was the first thing i checked). I compared the drone with another starling 2 drone during arming, the drone not flying (the one i am trying to get fixed) makes more noise, as if the propellers are spinning with higher power while the other drone (the good one) doesnt make as much noise. Also, a point to note, the drone has been working fine since may 2025, up until two weeks ago, so I don't know what might have caused this.

@Eric-Katzfey HI, I have attached a flight log.

Thanks!

@Zachary-Lowell-0 Hi, let me explain what i meant by hovering mode. There is a 3-way toggle switch beside the kill switch in the transmitter (toggling down switches to position mode, toggling up switches to the autonomous mode, while toggling to the middle maintains the drone flight positioning. I have another drone that when the button is switched to the middle, it maintains the drone position (thats what i meant by hover mode). My other starling 2 drones maintains their positions when the switch is toggled to the middle position, but this particular starling 2 drone doesnt.
