Processing the captured images into a 3D mesh and a clean texture uses Agisoft PhotoScan software, and requires only minimal manual tweaks. The actual capture process has completed in the blink of an eye. With all cameras pretty much synchronized, we don’t have to worry too much about minor movements of the scanned subject, as long as the shutter time is fairly short. On the software side the Canon Hack Development Kit (CHDK) allows us to control all 64 cameras using custom scripts. And as soon as we have such thoughts, a “battery” assembly line springs to life, wiring up the wooden batteries and soldering the power-supply connectors. And with us not being all that patient when it comes to seeing results of our labour, an ordering time of several weeks made us wonder “If we’re building the whole thing ourselves, surely we can make our own external power supplies as well”. Unfortunately the official adapter comes at a cost. Throw in a significant amount of USB cables, add some USB hubs, grab some wood and hardware from your local DIY store, add some bright LED strip for lighting, and you have all the ingredients necessary to build your own scanner.īeing the efficient people that we are, the idea of having to charge and replace the batteries for 64 individual cameras at each session did not sound like the most effective solution. You visit your local camera vendor, and empty their basket of 64 Canon Powershot A1400 cameras, which should suffice to build 8 portable 3D scanning poles. So what do you do when you don’t necessarily have a lot of permanent space, when you ideally want to obtain a scan in a single shot, and you want to do all that on a budget? Well, you build your own solution of course. At that point you have wide variety of different options based on different capture technologies, big bulky machines, hand-held devices and scanners that can take quite a while to obtain a scan. So you have an animation and simulation project, and want to scan people to get their high-resolution 3D meshes. Building your own 3D scanner out of off-the-shelf parts
