Scaling ODM

ODM is a docker image, so in theory it could be put on AWS, push the images to a bucket, spin up a lot of instance for the processing and scale back when done. I would like to know how to execute this but at the moment I can get all my processing done here so there’s no reason to invest more time in it now.

• Meshlab

Collection

Processessing

These come out as abc or ply, neither of which are currently supported formats for Potree. Therefore, we’ll need to convert them which leads us to:

Potree converter

https://github.com/potree/PotreeConverter https://github.com/potree/PotreeConverter/releases

Install

Run

```{Powershell}
.\PotreeConverter.exe G:\dronedata\KS_LearnedFlume\sedflume\20210310\meshroom\MeshroomCache\ConvertSfMFormat\c2ffbee2f8065999d1a8e24503cb345094f673f4\sfm.ply -o G:\dronedata\KS_LearnedFlume\sedflume\20210310\meshroom\PotreeConvert
