Calibration FIles

[Shivam Sehgal]

Hi I have 4 starling drones, would it be possible for me to get the original calibration files?

M23000001FM
M2100000J5D
M23000001FK
M22000006HK

@Shivam-Sehgal unsure what you mean by calibration files? As in files for the camera calibration? PX4 Calibration? IMU Calibration? If you specify we can further help. Also most of these parameters for the originals live on the drone under /usr/share/modalai

@Shivam-Sehgal Assuming you're referring to the camera calibration files, I will send you an email

@Zachary-Lowell-0 Hi Zach,

I wanted to clarify my concern regarding calibration files. I understand that many sensors, like cameras or IMUs, can be calibrated individually, so why do people often ask for calibration files tied to a specific serial number? ( I guess these might be the intrinsic parameters for the cameras)

For context, I had updated a couple of my drones, and now I’m concerned about whether I might have overwritten or used incorrect parameters during the updates. Could you explain when calibration files are critical?

Thanks,
Shivam

@Shivam-Sehgal Re-calibrating cameras if the calibration files are lost requires a precise calibration board which many customers don't have, which is why we back them up in our database before shipping the drones. These calibration files (extrinsic and intrinsic) are specific to each drone.

gyro, accel, and other sensors can be easily re-calibrated on the bench by the user without any extra peripherals.
