![]() This is a scan of one of my anvils which I shot with a Samsung Galaxy S5 using the stock camera app. If (or I should say when) something goes wrong with the scan you don't have easy access to the photos to try something else. A short coming of the current 123dCatch is that it doesn't save the photos to your phone (at least the android version I used didn't). You might not want to do this on your data plan, but it could be a handy feature on wifi. Then the app up loads your photos to their server for processing. For instance, the 123dCatch app from Autodesk uses your phone's sensors to measure what direction you are pointing your camera and to coach you through making a good scan. The power of the scanner app goes beyond just taking the photos. The real potential of the phone as scanner is in dedicated scanner apps. Most modern phones come with a pretty deent camera and there are aftermarket camera apps which will give you better control. If you have a smart phone it may be the best place to start. The some of problems have to do with me not being a competent quad copter pilot. It actually works and the results aren't as bad as I had expected. It might also be possible to optimize software to handle huge numbers of lower resolution images.Īs an experiment I made this scan using VGA resolution frame grabs from the on-board camera of a $50 quad copter. There may be a future for photo scans from video especially when we start to see affordable 6k and 8k cameras which can record uncompressed images. Most have tiny sensors and inexpensive optics which are optimized for shooting video, but they don't produce very sharp still images. The resolution of video frames is nowhere near what still cameras produce. It is a good idea in principle and it works in practice, just not that well. The pictures are taken so rapidly that it is almost impossible to not get enough overlap between them. ![]() So all we should need to do is wave the camera around the subject as if we were painting it to capture all the photos we need. Since we need lots of photos of a subject from all angles a logical question is "What about video?" Video cameras usually capture 24 pictures per second. The more sophisticated systems can take as much time and money as you want to give them, but can reward you with amazing results. Most of the free packages don't offer many options which makes them easy to use when they work. The software is pretty easy to get started with. You don't need to be the next Ansel Adams, but it is helpful if your photography experience goes beyond shooting selfies. Shooting the photos takes a bit of practice. By identifying enough of these spots (sometimes literally millions of them) the program is able to make a digital reconstruction of the object, suitable for amazing your friends, embedding in your latest video game, or, sometimes, 3d printing. The photos are fed to a program which identifies individual spots on the object and, though a combination of trigonometry and dark magic, deduces their location in 3 dimensions. Every part of the object must appear in at least 3 photos to be captured. You take a bunch of photos of an object you want to capture. If you want to learn more about 3d scanning and printing be sure to check out my podcast " 3d Printing Today". Just click on the white triangle to start, then you can experience the scan in 3d. Throughout this instructable you will find embedded 3d scans which you can explore thanks to our friends at Sketchfab. Combined with a little technique and some inexpensive or even free software, your camera becomes the world's most versatile 3d scanner. This tool, which will allow you to capture the world in amazing 3d, is a simple camera. It might be in your pocket, or you may be staring at it as we speak (so to speak.actually I'm writing and you are reading, but you know what I mean). The most amazing thing about 3d scanning is that you probably already own the best tool there is for it. Now you can do that in 3d with real stuff as well. Think of everything you can do with a picture in Photoshop. You can also use the scan as a starting point for a new creation. With a 3d scan and the right printer you can reproduce any object at any size from a house to an earring. There are many ways to make a 3d model, but one of the coolest is to 3d scan an existing object. We are now capable of printing almost anything provided we have a 3d model to work from. If you haven't been living under a rock for the last few years you have probably heard all the cool stuff that is going on with 3d printing.
