Hi, nice and simple video Can the same calibration file be used every time I change lenses?

Hello, no you would need to recalibrate every time you change the lense to make sure you have the most accurate calibration possible

Cool! Amazing video and spot on instructions. Ok, my plan was calibrate 24mm and leave file on one SD card, calibrate 35mm and leave file on a different card. And then just insert then right SD card for the lens I am using. I know it’s not perfect but I can’t see having to calibrate every time I switch them. Thoughts? Also. Anyone see the 24mm lens has really bad fish eye! Phots have all four corners cropped off. But when I make an ortho it works perfect? But pictures suck you have to turn on dewarping.

Thanks for watching! I like the idea of having the 2 SD cards pre-loaded with the calibration file. I cant speak on how this will impact accuracy down the line though. DJI reccomends recalibrating every time a lense is removed/put on. The pre loaded calibration that you have on the SD cards could be marginally off every time. The idea is everytime you reattach a lense, something about it could be a hair off compared to last time. As far as the 24mm lense goes, I myself haven't used it so I can't really comment.

Hello, thanks for the video. I have been trying to figure if my Dji P1 needed to be calibrated. I bought it new from a Dji dealer. The P1 came with a 35mm lens. My sales man never told me anything about needing a calibration. My unit was new at purchase. Do you think it came calibrated with the 35mm or should I do the steps in your video. How high did you fly and the speed.

The P1 does NOT come calibrated out of the factory. Unless your salesperson did the calibration for you, your device is NOT calibrated. I would reccomend performing a calibration flight on your own, it will make your P1 just that much more accurate. I flew this mission at 100m high, and left the speed at the default speed.

Thank you for your video. Can we use other processing software such as Pix4Dmapper or Pix4Dmatic?

Not for getting a dewarping calibration file, no.

Hi, why my pictures are white ( photos Not clear)

What software do i need to generate the SFN file? I dont have TERRA. Any other softwares (Pix4D, Bentley etc) or free softwares that can generate this? Thanks

Hi, could calibration be performed by obtaining the "sfm_report.json" file with another sw such as agisoft metashape professional? Thanks in advance for your reply. Greetings

How do we know if the calibration file worked?

Look at one of the image files from the P1, right click it and open with notepad (or any other text editor). Do a search (ctrl-f, cmnd-f) for "drone-dji:DewarpData=" if you are able to find the DewarpData in the image XMP field, your calibration is successful!

you can also when running a new mission in the AT report, checking if uncertainties are small between initial and optimized camera internal parameters

Why wouldn’t dji offer a properly calibrated json file for each size lens

I imagine there is no way to guarantee that all lenses are identical, thus using a "Default file" may not apply to your lense as it could be slightly different. By creating your own file, your creating one specific for your lense and the way its fixed onto the P1.

Does pix4d have a comparable output for the 'sfm_report.json' file?

This can only be done with DJI Terra

What do you do if you don’t have Terra???

I got 6 months free with my P1 so I am using that to calibrate my 24mm and 35mm lens. Bit now inside terra so much (L1 as well) I like it better than drone deploy. So I’m going to buy a subscription.

Actually this is not the lens calibration but, a generation of calibration file process that will be used when using dewarping option. Which actually should be turned off when using third party software like Metashape, Pix4d or other. From what I understand If you don't use dewarping option this process gives you completely nothing :)
