Which take us to the first step towards a good Structure from Motion scene or model: getting usable pictures. Agisoft PhotoScan Tutorial Agisoft PhotoScan is a photogrammetry software that allows you to build 3D models from digital photographs. You begin by adding pictures, either singly or by folder. As such, both the model of video card used and the number of GPUs present in a system can have an impact on the amount of time those steps take.


If you do some cleanup between the Align Photos and Build Dense Cloud steps the quality of the final model can be improved drastically. PhotoScan makes use of the video cards in a computer to assist with the computation of certain steps. The workflow dropdown menu is laid out in order: Add Photos-Align Photos-Build Dense Cloud-Build Mesh-Build Texture. For smaller models that you want to get from all angles, you can get one or more chunks with the object upright, then one or more chunks with the object upside down. You might use separate chunks to speed up the modelling time by processing smaller sets of photos at one time. I most often use the configuration seen in the picture, though I often close the console pane if I'm only working with one set, or chunk, of photos.Ĭhunks are separate sets of photos that can be merged after going through the entire workflow in each set. Those can handle up to 128GB of memory, three video cards. It is limited to 64GB of memory, though, and showed weaker performance in the Build Dense Cloud step - so if either of those is a concern for you then an Intel Core i9 processor will address both issues. The panes can be moved by clicking and dragging if you want to customize your view. Of the CPUs we tested, Intels Core i7 8700K was the fastest overall for PhotoScan. These, and the toolbar, can be shown or hidden by clicking view>panes> then selecting which ones you want to display. wptabs modevertical wptabtitle Load Photos/wptabtitle wptabcontentBegin by adding the photos used to create the model to an empty project in Photoscan.

There is also a console pane which gives text information on the processes being run. In this post we will demonstrate how to use bring a photogrammetric model for which georeferenced coordinates are available, using Agisoft’s Photoscan Pro and ArcGIS. Along the bottom you see the Photo pane, and along the left side you see the Workspace pane. In addition to the pane that shows the model in progress (or the photo being masked) there are two other panes.
