The first step to perform is to edit the scan, which entails erasing the background, base, or other unwanted elements, like the scanner and computer cords, from the scan. I was familiar with the steps from watching the tutorial, but she was able to go into greater depth about everything. Once I got finished laughing at how I had broken every single rule of good scanning on my first try, Kopteva discussed the scan processing workflow with me.
Instead, Kopteva said I should draw some dark lines on a white piece of paper and use that for the base. I also learned that shiny, reflective surfaces-like my teacup-are much more difficult to scan, and that contrast doesn’t just mean putting a flat black surface under the scan object, like I had done with my first ill-fated scanning attempt, or using my red tablecloth. In terms of texture, scanning works better with high contrast, multiple colors, visible color borders, and unique patterns. Corners and edges are better than round geometry…again, like a teacup has. It should have rich geometry, as opposed to the flat geometry you’d see on a teacup. To successfully track an item, it needs to be a little larger than something like, say, a teacup. Kopteva explained what constitutes good geometry, as compared to bad geometry, when it comes to scanning an object. Additionally, if you have other objects near the scan object, like your 3D scanner box, you’ll likely capture them too, so either move them out of the way or prepare for a lot of editing. You need good lighting, preferably from a fixture and not natural sunlight streaming in through a window you need to ensure that the scan object is immobile and determine how difficult it will be to scan ahead of time and while you’re scanning different angles of the object, you need to keep moving your wrist consistently at a steady pace, similar to spray-painting. She provided and went over two very helpful handouts with me, the first of which covered the basics. My breakthrough came after the first of two training sessions with Olesya Kopteva, Artec 3D’s Training and 3D Scanning Team Leader. It definitely wasn’t the best result, but I felt satisfied that I could at least tell what the scan was in the software, which had not been the case with the teacup, as you can clearly see above. It was really more of an accident instead of a plan, as I’d captured some of it in the background during one of my attempts to scan the teacup and realized it was showing up pretty well. I tried one more time that night, with something completely different: our mini organ with a framed photo of a favorite Friends quote on top. The distance from the scanner to the object is displayed by color in the frames, and just like traffic lights, green means go (or good in this case), and red means stop (not so good). I learned that, for best results, I should keep my scan movements in the middle three boxes on the left of the screen, known as the distance color map, which you can see in the image above. This way, I could make sure I wasn’t moving the scanner too fast or too slow and had it the right distance away from the scan object. One of the first things I learned was that I didn’t need to look at the object I was scanning, but instead at the computer screen.
ARTEC STUDIO HOW TO
The Studio 15 software was really great at explaining what the problem was, and how to fix it. So, before I did anything else, I watched a few of the tutorials, and then got to work setting everything up. When the software opens, a menu directs you to several online tutorial videos, including one about the Artec Studio interface and another about basic scan processing. The laptop was pre-loaded with Artec Studio 15 software, which was just released this summer and has a variety of useful features, such as an HD mode for high-resolution scans, excellent geometry tracking algorithms, and Smart Base Removal. Along with the scanner, Artec 3D sent me the fanciest laptop I’ve ever seen: an MSI system with light-up keys and a wireless mouse to go with it. The Artec Eva came well-packaged with the various cords as it operates by USB streaming through an external computer, it has to remain plugged in to the computer during scanning.
