こんにちは！
都市部のオルソモザイクを作成しようとしているのですが、画像が正しくつながらず困っています。これまでにいくつかのプロジェクトでDrone2Map（標準ライセンス）を使用しており、この問題が発生するのは今回が初めてです。
「None」と「Sparse Point Cloud」の両方のオルソ補正方法を試しましたが、どちらも必要な結果は得られませんでした。
何かアドバイスをいただけると大変ありがたいです！
Hi @StormwaterAdmin,
One the first things that stands out is the ground control that you are using. It looks like you are getting some pretty high residual values which can negatively affect the adjustment and output quality. Have you processed without these control points and do you see the same seamline issues?
Additionally, are you on the latest version of Drone2Map? (2023.2.2)
If not, then I would highly recommend you update as we have done some significant improvements to orthomosaic generation. Specifically, True Ortho products are now the default for both Standard and Advanced licenses. https://doc.arcgis.com/en/drone2map/2023.1/get-started/whats-new.htm#ESRI_SECTION1_7E15549EFB7E47C3B441C95A47836E7EPlease test processing the flight on the latest version and let me know if you are still seeing these issues.
Regards,
Mark
@StormwaterAdmin SOme questions for you based on your covergae.
1) When you flew the area dis you have at least 70% image covergae?
2) What type of flight pattern dod you fly? Area Survey, CrossHatch, Random?
3) Can you show a screen capture of your flight pattern
4) for the stitching method you should use higher density point clouds if oyu have sparce image coverage, as it is this characteristic that D2M uses to tie image points together
Cheers
Gordon
I used DJI GS Pro photomap with a 80% front and 70% side overlap. I have attached a photo of my flight pattern.
Thank you!
Hi @StormwaterAdmin,Would mind sharing the processing report from the project?
Thanks,
Here you go!
I updated to the latest version and the ortho is looking much better! Thanks for the help.
Glad to hear! Happy to help
