A Simple Mirror Makes 3D Scanning More Efficient

If you want to get a complete 3D scan of something, you need the scanner to “see” the object from every angle. Handheld scanners and turntables both help in that regard, but unless you’re hanging the object from a thread, there will always be an area the scanner can’t see — usually the surface it rests on. That means you have to reorient the object at least once to scan the entire thing. But it turns out that you can avoid that by simply putting a mirror under the object.

Thomas_openscan posted this idea and his testing to the r/OpenScan subreddit and admitted that he wasn’t sure if it “is a stupid or good idea.” Personally, I think it is pretty clever.

For the test, he used a DIY OpenScan Mini 3D Scanner. He then placed a round mirror on the rotating pedestal and performed a scan.
