drone2mapを使用して建物の側面のテクスチャを含む最高品質の3Dモデルを取得する方法は？

Question

<\/HEAD>小規模なサイトのためにdji inspireから素晴らしい画像を持っています。地面に対して非常に直交した画像はdrone2mapで3Dサーフェスを生成しますが、ご想像の通り、建物の側面は屋根と比べてテクスチャがあまり良くありません。建物の側面を取得するためにより斜めの角度のドローン画像を含めると、結果として得られるdrone2mapの3Dメッシュは完全に乱れてしまいます。最適なマップとモデルを作成するための最適な飛行計画や直交ビューと斜めビューに関する特定のドキュメント、または画像から優れた3Dテクスチャ付きサーフェスを生成するためのdrone2map内の異なる設定はありますか？<\/P><\/BODY><\/HTML>

John,

If you have very high oblique images that include a lot of horizon / sky it is going to be difficult to build a 3D mesh successfully. As Ruwan mentioned above, little to no sky is best.

Drone2Map will allow you to process both NADIR and Obliques together, and users are reporting an increase in quality of their final products by doing this approach.

Thanks,

In my experience, having little to no sky in your oblique shots leads to much better modeling.

That helped a lot but there are some places in my textured mesh where its still trying to create mesh from sky. Are my images too oblique?  Would a best practice be to ensure that oblique images do not include any sky?  Also from my drone survey I have about 100 image that are very orthogonal in nature (no sky) and about 80 that are very oblique in nature (include sky).  The 2 sets are from different altitudes.  Can I process these images all together, or should I not mix like that?  Should I instead attempt to maintain a basically constant altitude for the survey?
