Title: Distinguish lens-distortion-corrected image (DJI Phantom 4 RTK)
Post by: space111 on March 19, 2022, 01:40:31 PM

Hi Alexey,

Metashape can distinguish different cameras(same model) based on SN information from EXIF tag in the photo, and read pre-calibrated parameters for post-processing. ;)

However, DJI Phantom 4 RTK has a setting whether to turn on lens distortion correction. when this setting is on, the image will not contain any pre-calibrated parameters.
When import a folder with a mixture of two types of photo, the result of current version of Metashape (1.8.1) is that all photos will be considered without pre-calibrated parameters.

Is it possible to classify these two types of photos and consider they are separate photo groups ? please check "dewarpflag" and "dewarpdata" tag from EXIF tag in the attachment. Due to the size limitation, I am not able to upload raw photo,  let me know if you need raw photo for testing.

Thanks.

You can throw away the DeWarp photo, Metashape cannot work "correctly" with it.
(Unless you don't care so much about precision.)
