I noticed that some of my ODM outputs folder do not include cameras.json, images.json and img_list. There is no optical zoom, so if stills photography is your main aim, then you may want to consider a drone with a 16+ megapixel camera, interchangeable lenses. I found the free version of Davinci Resolve 15 (or 16 beta) works fine for this correction as well. I am happy to contribute to the Docs once I get a better handle on this. I guess if I process all those images combined I should obtain robust lens distortion parameters. The parameters for camera interior orientation and lens distortion were calculated using Topcon Image Master Calib software. However I do not have a flight with images at a 20° angle as suggested, and will not be able to get them anytime soon. 4 RTK offers unparalleled accuracy, every single camera lens goes through a rigorous calibration process where radial and tangential lens distortions.
in double grid, camera angle of 80 an 70 degrees The paper proposed a new approach based on the total calibration in order to estimate the distortion of lens system in DJI Phantom 4 Pros camera. The camera is said to have improved chromatic aberration (reduced by 56), and lens distortion has been reduced by 36 compared to the Phantom 3 Professional.I flew the same 100x100m area with different settings combinations using Pix4D:
The recently added sections about high quality orthomosaics and DEM were certainly very helpful. The camera is the same one thats on a standard Phantom 4, but with the Phantom 4 RTK, each camera has its radial and tangential lens distortions measured. Thanks for your replies and am trying to figure out what are the best flight settings to map canopy cover and height of sparse vegetation as in the linked pictures above.
