Previously, I only managed to create low quality models, due to an error in the program, but I have now managed to make really good models of both objects and features. Up to now, the best solution I have found is Agisoft Photoscan, which I had already used in the past but not to its full extent. Having said all this, I’ve started investigating new software, to see if there is anything that can bring improvement to what I already have with 123D Catch. I think that is utterly brilliant, as it means it doesn’t halt research, but it still allows revenue for the developers if the user is himself making money from the software. Recently they have released a paid Pro version that provides all the same results but allows the program to be used commercially. I find that it is by far the easiest program to use, yet the results are still amazing.

Speeding up Photoscan’s dense cloud generation, 2018 version.Photogrammetry tutorial 12: my workflow for Agisoft Metashape as a diagram.Photogrammetry tutorial 13: How to handle a project in Reality Capture.Please note that, obviously, you can use both ways of marker detection shown above, but I am only giving you the chart for splitting the set for marker detection. Lastly, if you choose to build your model directly from the depth maps, here is a version for that. These are steps that refer to in-program commands in Photoscan you can simply start directly. These are steps that require you to do something beyond simply starting a software command. This approach can be quite a time saver! All the target-free photos are added to the same chunk only after marker detection has been completed.īelow, in contrast, is the diagram for cases where splitting the image set into target-bearing and non-target-bearing parts is not worth the effort. As the diagram suggests, I recommend loading only these images into Metashape Pro initially, so that the “Detect Markers” command can be applied only to them, and not the many other photos you shot. If you do as I say, these images will be at the beginning of your photo set. Above, you see the diagram for a project with many images, only few of which show targets for auto-recognition. It also shows which steps of the process you actually need to do yourself, which steps Metashape does, and which ones you can batch process easily.Īctually, there are THREE flowcharts, differing in a tiny detail at the very start and in the way your model is built (via dense cloud or directly from depth maps). Here, I’ll show you a flow diagram, which gives a nice concise overview for those who do not need to read up on all the details or prefer to have an overview at hand in parallel to the long-winded description of all the things you need to click. The last tutorial on how to handle a project in Agisoft Metashape Pro describes all the steps I usually do in some detail. Updated other charts to new program name. EDIT 06/2022: added chart for using depth map based mesh generation.
