| A 3D scanner is a device that analyzes a real-world object to collect data on its shape and appearance. Then the collected data can be used to reconstruct digital three dimensional models. The collected 3D data is very useful for a wide variety of applications, especially for the entertainment industry in the production of movies and video games. There are plenty of technologies for digitally acquiring the shape of a 3D object. Most of the well known 3D scanners are active scanners, which emit some kind of radiation and detect its reflection in order to probe an object. The active scanners are precise but expensive, because most active scanners are laser-base. Our group is trying to make a passive scanner without using any laser, which is affordable for home usage, like in X-Box 360. Our passive 3D scanner is camera-based. First of all, fix a sample object in the center of circle, and then our camera move around the circle to collect the data of the object. Second, acquire discrete frame from the video by the same difference angular degree. Third, do segmentation on each frame. That is acquiring the information of the sample object from each angle. Forth, put the information from each angle on our 3D matrix. Overall, we can reconstruct our sample object. |
