Rather, I try to make sure that all my photos show my specimen with a totally immobile background, or one that has no features at all, across all sets of photos I take. I do not use separate chunks if I can help it. on separately, then align and possible combine them later. Metashape allows using several separate chunks, which you can have the software perform alignment and dense point cloud building and meshing etc. So, how do I do these steps? Placing the photos in the software This can be done at any time after Step 1 (I usually do this after step 3 or at the very end), and thus I will put the info on it at the end of the post.

If you want to, have software reduce mesh size and calculate a texture for the mesh.Īt some time in between, you also need to scale your model.

Mesh may need cleaning up unless you used masks.

OR have software build a polygon mesh directly from depth maps.

AND have software build a polygon mesh.

EITHER Have software build a dense point cloud, which may need manual cleaning.

Clean up the sparse cloud, create a mesh from it, and (optional) mask your images based on this mesh.

Have software align photographs, including building a sparse point cloud (tie points).

PLEASE NOTE: this post assumes that you are using Metashape Pro, not the Standard version! Some steps described below are not available in the Standard Version!īefore we get into the details of Heinrich’s Photogrammetry Work Scheme, let me list the basic steps of building a 3D mesh from photographs:

Note that I decreased model size from ca. They’d run through the “Workflow” menu of Metashape and end up with model that were OK or so-so, based on photographs that should deliver really excellent models.īelow, therefore, I’ll describe how I use Metashape to create high-quality models. Recently A long time ago, however, I realized that a lot of people also have problems making the most out of their photographs in their photogrammetry software, most of them using Agisoft‘s really easy to use Metashape (previously Photoscan). Or with the set-up for easy and quick models that show the underside of a specimen, too. Usually, they needed help with the photography – understanding how the program works, so that they take the right amounts of photographs in the right places. Over the course of the last few year decade and more I have helped a bunch lot of people with their photogrammetry projects.

Up to speed with the latest version of Metashape.
