Meshroom Pipeline Starting with a Point Cloud and Images

[Ryan TrvScanlon]

I am a novice with Meshroom, but from what I understand it sounds like you can create custom pipelines. I believe those pipelines can start at any point in the process. I'm trying to find some tutorials or at least code examples that show this.

In my case, I have an accurate dense point cloud. I also have a series of images that represent the perspective of where the points in that cloud were captured. Finally, I have the position and orientation in 3D space of each of those images.

So in the pipeline, I don't need the point cloud creation, or the camera pose construction. What I do need is the 3D mesh reconstruction from the point cloud and the texture mapping based on the images. Does anyone know where I begin? What file format do I specify the camera position and orientation and where to do I place this file? How do I specify the nodes in the pipeline, and what file format is used for that?

Pointing me towards any known examples would be very helpful.

Thanks!
