Physical targets to create a 3D model of topography

[kobihavu]

Hello Forum,

In our research group we take photos of an evolving topography and generate 3D models out of them using Agisoft Metashape.
One of our experiments involves modelling a topography which is very bright and without much texture, a white planar surface (as can be seen in the attached photo) that undergoes a non-uniform tectonic uplift (1cm/hr-3cm/hr).

Are there any tips on how to best utilize the models of the evolving topography despite the issues this texture might cause? One of my thoughts was placing physical targets on the surface to make it easier for the software to find mutual points. Any suggestions?

Hi Kobi,

Looks like you are working in a controlled lab environment, hence you should be able to make use of a 'scanning with projection' workflow. Have a look at this website for more information: http://www.pi3dscan.com/index.php/instructions

All the best.

P.S. I am just curious what kind of research/experiments you are doing...
