@Alex-Gardner @Matt-Turi
Thank you for quick reply. It help me a lots.

In conclusion,

• via cable, I can use adb pull to download file.
• via local network, I can use scp to download file.
• latest version, I can download file via voxl-portal Map page.

According to the post, I used the new version of voxl-mapper and I can save the map into gltf, obj, ply.

If I want to download the gltf file from the drone, I have to use a cable to connect with drone and my mac. So that, I can use the scp command to download gltf, obj, ply files from the drone.

Are there any other ways to download the gltf, obj, ply file without using cable?

If someone knows that, I would be appreciated it.

Hello @Matt-Turi
Thank you for your response.
For some reason, I can not use the latest version voxl-mapper.
I want to know how to generate mesh.ply in old version of voxl-mapper.

I clicked the 「save map」button by voxl-portal and I went to the path /data/voxl_mapper/.
I found the tsdf file and esdf file and both are not empty files. However, I found the mesh.ply file is empty. Do you know why the mesh.ply is empty file ? And how could I solve it ?

Dear Matt,
Thank you for your quick response.
I tried to save the map and copy the mesh.ply file from the drone.
However, I found the mesh.ply file is an empty file.
Do I leak any steps or what should I do in Voxl-portal?

Glad to hear there would be an api to do that !

Thank you

I used the voxl portal to save map and I can found the map file are saved in the /data/voxl_mapper/.
I found the files are ESDF(Euclidean Signed Distance Functions)とTSDF(Truncated Signed Distance Functions).
I want to convert them into other format like glTF or Wavefront OBJ(.obj) or other format.
I want to open the map files as a 3D model maybe in software like Blender or else.

Do anyone know how to do it ?

Thank you.
