The 3D scanner is a scientific instrument used to detect and analyze the shape (geometry) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often used to perform 3D reconstruction calculations to create a digital model of the actual object in the virtual world. These models have a wide range of applications, including industrial design, flaw detection, reverse engineering, robot guidance, geomorphology, medical information, bioinformatics, criminal identification, digital artifact collection, film production, game creation materials, etc. application. The production of 3D scanners does not rely on a single technology. Different reconstruction technologies have their advantages and disadvantages, and the cost and price are also high and low. There is currently no universal reconstruction technique, and instruments and methods are often limited by the surface characteristics of the object.
