Drone2Mapで作成された点群は3D ArcGIS Proで表示できません

皆さん、こんにちは、<\/P>

<\/P>

Drone2Mapを試すためのパイロットプロジェクトを始めました。私のプロジェクトは主に草地と数本の木がある小さなエリアです。使用したドローンはDJI Mavic Pro Quadcopterです。撮影した写真はすべてナディア（真下）でした。<\/P>

Drone2Mapから得られた成果物はオルソ画像、DSM、ヒルシェード、そして点群です。プロジェクトの処理レポートを添付します。いくつか問題があります：<\/P>

- DSMと点群は画像内の木を検出しませんでした。<\/P>

- 点群は生成されました（2Dマップでは表示できます）が、3Dで全く表示できません。<\/P>

<\/P>

私はDrone2Mapは初心者なので、何が起こっているのか全くわかりません。多く調べましたが、同じ問題に遭遇した人はいないようです。<\/P>

<\/P>

どんな助けでも大変感謝します！<\/P>

<\/P>

よろしくお願いいたします。<\/P><\/BODY><\/HTML>

Hello Vi,

Regarding to the issue 'No tree on DSM',
it is generally said that tall objects such as tree and electric pole are difficult to detect especially when its surrounded by low objects. I don't know how you flied your drone but I recommend you to try capturing plan below;
  -Nadir camera-Higher overlap (≧ 80%)
                         -Higher altitude (less resolutions but helps increasing overlaps)
                         -Double grid flight
 -Oblique camera-Same as above
Plus, poor contents' differences (homogeneous visual content) such as grasses and forests are difficult to match keypoints and it would cause distortions. (if your orthomosaic result have problems, i guess this is the cause)
When the photos doesn't have much contents's differences, Processing Options > Initial > "Calibration Method: Alternative" on D2M would be helpful.

Regarding to the issue 'No pointclouds in 3D view' (I believe that is happened on ArcGIS Pro),
I assume the pointclouds might be buried under the ground. You may find them when you check-on Contents Pane>Scene>Properties>Elevation Surface>Allow underground navigation. You can adjust the height from Contents pane>Point Cloud>Altitude>Cartgraphic Offset.
I use Japanese edition so the terms for setting might be different from the one I wrote above.

Any additional comments are welcome!

Hope you'll solve the problem soon.

Best,

Miki
