Briefly about 3d scanning #2 – Photogrammetry at home
We can safely say, that photogrammetry is the most popular way for creating a 3d object out of a real life subject. No need for poking around with probes, nor for shooting high-tech laser beams, ultrasound, just a few – ok, hundreds of – photos (see the picture above), taken from different angles.
Fortunately, there are a lot of options available for combining a heap of photos into a 3d model!
You can choose from some high-end solutions such as Autodesk’s Remake (formerly Memento), which can do all the job for you from creating the mesh from photos, to cleaning up the mesh, or even doing some measurements on the object. You can use your own computer, or the power of the cloud to do all the work!
Another stunning application is Acute 3d, which has some really impressive videos about how it has been used in scanning streets, or even whole districts, by using cars and drones rigged with cameras!
Thankfully there are some excellent applications for leisure users as well, like the famous 123d catch app from Autodesk for smartphones. Place an object on a well-lit, clean surface, run the app, and let it guide you while you take photos of your subject, then upload them and wait ‘till the cloud of Autodesk does the job for you, and enjoy your 3d object!
Want to scan something bigger, let’s say, like your house? No problem! Fly a drone around (in case you don’t have one, here’s our post from earlier about printing one), with a camera, the use DroneDeploy to turn the footage into a 3d model!
