3Dskanneri
3Dskanneri, or 3D scanner, is a device that captures the three-dimensional shape of real-world objects and environments and converts it into a digital representation. In Finnish contexts the term 3Dskanneri is used to denote such devices. Most 3D scanners are non-contact systems that project light or emit a laser and measure how the light interacts with the surface to reconstruct geometry. The collected data are typically a point cloud or a polygonal mesh and may be textured with color information. The resulting digital model can be used in design, engineering, heritage preservation, medical imaging, film and game production, robotics, and quality inspection.
Common sensing approaches include structured-light scanners, which project known patterns and compute depth from pattern distortion;
Output formats often include STL, OBJ, and PLY, among others, and post-processing is typically required. This
