I do not have a valid raster for parameterization + texturing from registered rasters

Question

This is my first time using Meshlab so I don't really know my way around the software or how to troubleshoot myself. Thought I would post in here in the hope that someone can help/point me in the right direction. I am using the software for a university project and my tutor shared the following tutorial video with me:

I have followed all of the steps but when I get to apply the texture I get an error message. To apply the texture I take these steps:

Filters>Textures>Parameterization + texturing from registered rasters

In the dialogue box that popped up, I changed 'Texture Size' from the default 1024 to 2048

After clicking apply the following error message pops up:

"Failure of filter : 'Parameterization + texturing from registered rasters' You need to have at least one valid raster layer in your project, to apply this filter"

I don't know what this means or how to get around it!

I would really appreciate it if someone can help get around this issue and help me learn what went wrong!

Thanks very much in advance,

Chris

Answer 1

Your "Bundler.out.list.txt" file is empty (0 bytes). Therefore, MeshLab never imports any of the images (i.e. rasters) and thus the error message.

Why is my Bundler.out.list.txt" file empty?

When you exported your dense model from Colab, there were no cameras "loaded" (...likely you chose to view the dense point cloud created after the Fusion reconstruction step, which unloaded the cameras...)

What to do?

Just import your sparse model into Colab, and when you see your cameras loaded, export a Bundler model. This will create the correct "Bundler.out.list.txt" file to use with MeshLab.
