3D scanner is a device that captures the geometry of physical objects and converts it into a 3D digital model. The scanner uses various technologies such as laser, structured light, or photogrammetry to capture the shape, texture, and colour of the object. The basic principle of a 3D scanner is to project a pattern of light or laser onto the surface of an object and then measure the distortion of the pattern caused by the object’s surface. This data is then
processed to create a point cloud, which is a set of 3D coordinates that represent the shape of the object. The point cloud can be further processed to create a 3D model, which can be edited or printed using a 3D printer. 3D scanners are used in various industries, including engineering, manufacturing, entertainment, and healthcare. They can be used for quality control, reverse engineering, prototyping, animation, virtual reality, and medical imaging. There are also many affordable 3D scanners available for home use, which are commonly used for 3D printing and DIY projects.
