サーフェスの再構築に失敗し、True Orthoを生成できません

Question

DJI Matrice 4eであるエリアを飛行し、そのエリアのTrue Orthoを作成するためにDrone2Mapを使用しようとしています。私のプロジェクトには2528枚の写真があり、それらをつなぎ合わせようとしています。処理は進み、100％完了と表示されますが、True Orthoは一度も作成されません。ログを見ると失敗を示すものもありますが、どのように修正すればよいかわかりません。<\/P> 以前、約1900枚の写真でプロジェクトを正常に実行したことがあり、マシンの推奨スペックも満たしています。複数の設定を試し、未校正の画像はすべて削除しました。<\/P> 何か助けていただけるとありがたいです！<\/P> ログを添付しました<\/P> <\/P>

Hi @JuliaLenhardt , we did have a file path length issue that could occur during surface reconstruction in 2025.2 that should have been resolved with 2026.1. Have you had a chance to test the latest release to see if the problem is reproducible?

Regards,

Mark

Hi @MarkBarker1! I'm having the same issue as listed here, but digging into the ProjectLog I see it fails when attempting to write to the project folder, which of course doesn't make sense since the folder is editable. Could it be an issue with the number of characters in the path? I made it as short as possible. See the attached ProjectLog and the error about writing to files in "C:\DroneProducts\Testflight2\Project\Process\SurfaceRecon\Images	mp_0"

Thanks!

Hi @MarkBarker1 ,

So I do get result folders but they are usually empty. One thing it does produce is a csv file with the image metadata. After looking at that it did appear that I had images with different focal lengths. I removed the images with different focal lengths and it is producing the true ortho.

So my best guess is that I bumped the zoom trigger and it changed a setting that caused it to fail. I will have to fun it on a smaller area and then stitch them together.

Thanks,

Jaron
