Now on line: Photogrammetry step 5 – using stacked pictures
Photogrammetry makes it possible to store, view and share information about a subject in 3D. But the technique has some limitations. One is that you need sharp photos of the subject you want to make a 3D model of. In macro photography the shallow depth of field can therefore be a problem. One time consuming […]

In this step I show you how to Select and delete free floating debris Select and smooth artefacts on the surface of the model Decimate the model Adjust the texture / UV map Read more here; Photogrammetry step 4 – Preparing a model for upload
Photogrammetry step 3 – masking from model is published
I have just finished Photogrammetry step 3 – masking from model. The result using the standard Workflow in Metashape can be seen in the left picture bellow. There is a problem with some unwanted artefacts. Agisofts Metashape also have a feature that uses depth maps. It was this method that was used in Photogrammetry step […]
Photogrammetry step 2
I have just finished step 2 of the photogrammetry tutorial. This time I create a 3D model from 286 pictures. For this tutorial I used Agisoft Metashape standard, Canon EOS 6D camera with Canon EF 24-70mm F/4L IS USM objective. The subject is the same runic stone as in Photogrammetry step 1 where I demonstrated […]
Photogrammetry step 1
Photogrammetry is a technique that combines several pictures of a person or an object into a 3D model. This can be used for multiple purposes such as movie production, making scientific models for 3D printing, product design and more. Even if photogrammetry can be very useful it has a lot of drawbacks. In this series […]
