Top 13 of the best photogrammetry software
Posted By Lucie Gaget on Jun 12, 2018 |
Photogrammetry can be really useful for various applications. It is a way to create the digital image version of an existing object, person or landscape. You can obviously try to use a 3D modeling software and design it by yourself. It would be a waste of time, and if you are not an advanced designer, you might not get the perfect 3D representation of what you want. Here, the easiest solution is certainly to use a 3D scanner or a photogrammetry software. The question now is: how is 3D scanning working? How can I 3D scan an object? We already saw on our blog how to 3D scan with a tablet or with a smartphone. Let’s see more in details what is photogrammetry and what are the photogrammetry software tools that you could use.
Using photogrammetry technology
What is photogrammetry?
Photogrammetry is a science of making a measurement from photographs. This method is using the parallax obtained between several pictures, taken from different points of view. Photogrammetry can be used to record complex 2D and 3D motion fields. It is imitating the stereoscopy of the binocular human vision, and it is actually used to get all the information of existing physical objects. Indeed, this process collects the data regarding the shape, the volume, and the depth of the subject that you are trying to scan.
This is the method used to turn several pictures into an accurate 3D design.
How does photogrammetry work?
Photogrammetry works by extracting the geometric information of a two dimensional image. By combining a lot of pictures, you will be able to create a three dimensional image. Photogrammetry is the process used to create the 3D scan of an object, using multiple images. Indeed, it is possible to make the 3D model of an object with several pictures of this object, ingeniously taken from different points of view, in order to get a complete representation of the object. For this, you don’t necessarily need to use a 3D scanner, a simple smartphone, a tablet or a good camera can be used, with good image stabilization!
Thanks to photogrammetry, and a serie of complex algorithms, you will get a digital 3D model using multiple photos of the original real world object thanks to a powerful reconstruction process. The more pictures you have, the more precise your 3D design will be. It is also possible to turn one picture into a 3D model, but obviously, you will not get an optimized result with only one picture.
Why should you use a photogrammetry software?
3D scanning could be useful for various applications. It can be used to get a viable 3D model and make the most of the 3D printing technology using an online 3D printing service such as Sculpteo. But having a great 3D design is also an amazing tool for visualization.
Photogrammetry is useful for topographic mapping, architecture, engineering, or even geology! There are a lot of software tools dedicated to aerial photos, photogrammetry is really useful for geographical use. For instance, archeologists are also using it to create plans of complex and remote sites.
What are the best photogrammetry software tools
While choosing a photogrammetry software, you will have a huge choice. You will have to choose your software regarding your expectations: Do you need to upload several images? Do you want to focus on aerial images? Are you experienced? Do you want to try photogrammetry for the first time with a free software? Let’s discover what is the best solution for you!
If you prefer to use a smartphone application, check out our blog post on how to 3D scan with a smartphone to see what are the different possibilities and the best programs to create a viable 3D scan.
