If colour information is collected at each point, then the colours or textures on the surface of the subject can also be determined.ģD scanners share several traits with cameras. These points can then be used to extrapolate the shape of the subject (a process called reconstruction).

This 3D model consists of a polygon mesh or point cloud of geometric samples on the surface of the subject. The purpose of a 3D scanner is usually to create a 3D model.

Other common applications of this technology include augmented reality, motion capture, gesture recognition, robotic mapping, industrial design, orthotics and prosthetics, reverse engineering and prototyping, quality control/inspection and the digitization of cultural artifacts. These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality. For example, industrial computed tomography scanning, structured-light 3D scanners, LiDAR and Time Of Flight 3D Scanners can be used to construct digital 3D models, without destructive testing.Ĭollected 3D data is useful for a wide variety of applications. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects. Many limitations in the kind of objects that can be digitised are still present. The collected data can then be used to construct digital 3D models.Ī 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. 3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance (e.g.
