PHOTOGRAMMETRY
WHAT IS PHOTOGRAMMETRY?
Photogrammetry is a process for scanning existing objects using digital cameras, and using the captured photos to create 3D models. Objects, people and even places can be replicated in 3D using this method, and the models produced are suitable for 3D printing, putting them on the web, or even bringing into a game engine. This process has been used extensively in creating tangible 3D printed museum exhibits and populating video game environments with highly realistic digital assets.
Unlike other 3D scanning methods, Photogrammetry preserves photo-realistic surface color in the models it produces. Objects with a lot of surface detail work great with this method, as the algorithm that generates a model analyzes your photos on a per-pixel basis, looking for features it can identify across multiple photographs. If it can locate the same feature across several photographs, that feature can be triangulated in 3D space, allowing a model to be constructed from a plotted point-cloud.

Entire collections of objects can be preserved online for viewing or downloading using this method, ensuring collections are accessible from all over the world.
WORK FROM HOME
Our in-house photogrammetry resources are intended for capturing difficult scanning subjects and expediting the capturing of entire collections, but photogrammetry can also be done in the comfort of your home with any single device capable of taking digital photos.

ABOUT OUR SPACE
The Visualization Studio houses a Photogrammetry room dedicated to simplifying and expediting the process of scanning with this method. This can be particularly helpful for large-scale objects or subjects like people (that move slightly and need to be photographed quickly). Photogrammetry has the ability to preserve very high resolution color information on the surface of an object as the photos used in generating a model are mapped to the model’s surface. Depending on the subject, the precision of the resulting model can sometimes rival that of a laser scanner.
The Photogrammetry room inside the Visualization Studio is accessible on a walk-in basis. It is equipped with five automated Canon EOS 80D DSLR cameras that each capture at 4k resolution. It also offers several software packages for processing and modifying Photogrammetry models, including Agisoft Photoscan, Autodesk Recap Photo, Reality Capture, 3DF Zephyr, Autodesk Mudbox and Pixologic Zbrush. Models and point cloud data generated through Photogrammetry can be exported as *.OBJ, *.PLY, *.STL, *.FBX, Adobe PDF, *.3DS, COLLADA,*.DXF & *.U3D format. These formats are suitable for purposes like 3D printing, creating 3d collections on the web, or bringing content into a game engine for porting to an AR or VR device.
