Ortho mapping / Drone DJI mini 2 camera parameters

S_Hotes — Mon, 31 Oct 2022 07:17:58 GMT

I am trying to use images taken with a DJI mini 2 to create an orthomosaic in ArcGIS Pro. The Ortho Mapping workflow in ArcGIS requires camera parameters for the photogrammetric correction. I have found a post with such parameters for the Mavic 2 Pro in the DJI Forum (https://forum.dji.com/thread-206289-1-1.html). I'd be grateful if someone could share the respective camera parameters for the DJI mini 2.

The parameters required by the Ortho Mapping workflow in ArcGIS Pro are:

Camera Maker (here, 'DJI' was pre-selected after loading images taken with the DJI mini 2)

Camera Model ('FC7303' is shown in this field, but I haven't been able to confirm whether this is the correct number for the DJI mini 2)

Focal length (mm) ('4.49' is shown, but I haven't been able to confirm whether this is the correct value for the DJI mini 2)

Pixel Size on the Sensor (in mm) ('0.00176509' is shown, but I haven't been able to confirm whether this is the correct value for the DJI mini 2)

Columns ('4000' is shown, but I haven't been able to confirm whether this is the correct value for the DJI mini 2)

Rows ('2250' is shown, but I haven't been able to confirm whether this is the correct value for the DJI mini 2)

Principal Point X0 (mm) Y0 (mm) (both fields are empty)

Radial Coefficients K1 K2 K3 (all three fields are empty)

Tangential Coefficients P1 P2 (both fields are empty)

There is also a field called 'Camera File' with a button next to it that opens a window to locate a file on the local hard drive, suggesting that there may be files available that contain the set of camera parameters listed above. The information concerning possible file formats lists CAM, CSV and TXT as options.

Any help would be much appreciated.

Did you see this thread?

Mavic 2 Pro Camera Parameters - Esri Community

maybe something useful there

Thanks a lot, the thread addresses the points I would like to find answers to, but the drone and camera model are different.

Following - I have the same question. Haven't found a forum with relevant info yet for Mini 2 parameters in Arc.

I understand that a dji mini2 does not work with sitescan nor sitescan flight. As far as I know thats due to the sdk not being made available by dji so esri could not develop the sitescan software to include the mini2.

I use a phantom4 for fotogrammetry. Our dji mini2 is used for manually inspecting gutters and rooftiles.
