A 3d scanner refers to a device, which analyzes
objects, and collect data on it dimensions and shape. Laser scanning has many
types of uses, and 3D laser scanning is widely used in many different
industries. Applications for civil surveying, reverse engineering and industrial
architecture are some of is versatile uses. 3D laser scanning can produce higher
resolution, and faster 3D digitizing than other more conventional techniques.
Virtual reality techniques can be used to produce a virtual three dimensional
space from the desired architecture, and then used in computer simulations. 3D
laser scanning is also used to document rebar installations to allow inspection.
Other applications can include the investigation of accidents. An accident can
be 3D laser digitized, and a simulation of the accident produced allowing
various possibilities to be explored. Different technologies are utilized in
manufacturing 3D laser scanning devices, and each one has its limitations,
advantages and disadvantages.
