A 3D scanner is a device that analyse the real-world object or environment to collect data on its shape and possibly its appearance. The collected data can then be used to construct digital three dimensional models. The purpose is to develop a scanner which can automatically scan the object from all viewing angles. Then to generate point cloud necessary to create a polygon surface mesh, which can then be used for 3D print. Laser triangulation principle is used to generate required point cloud. According to the principle- laser dot, the camera and the laser emitter form a triangle in such a way that the length of one side of the triangle is the distance between the camera and the laser emitter is known. The angle of the camera corner can be determined by looking at the location of the laser dot in the camera’s field of view. Such information determines the shape and size of the triangle and gives the location of the laser dot corner of the triangle. These continuous dots can be constructed to form surface mesh using the power crust algorithm to form a digitized image. In this work authors discussed about construction and working of 3D scanner, increasing the point density to reduce errors and also converted surface mesh image to .stl format for 3D printing applications.
