There are many input devices available for users to digitise

There are many input devices available for users to digitise a solid object for reverse engineering usage. Among them is the 3D scanner. Explain in brief the process of converting a physical solid object to a computer generated 3D model using this 3D scanner.

Solution

For conversion of a physical object into 3d model reverse engineering needs to be applied Reverse engineering is the process in which physical object is identified by conduction a proper analysis of the function and structure witrh the aim of creating a virtual 3D profile Reverse engineering is an integral part of 3d scanning as to genrate the 3d model of a physical object 3d scanning techniques like laser scanning needs to be used Many types of 3d scanning techniques have been devloped but the most frequesntly used techniques are laser scanning and Cordinate measuring machine(CMM) CMM method has various disadvantages as it is slow and this method requires physical contact with the object Laser scanning is the best 3d scanning technique as it can do quick analysis, no contact with the object required and accurate results are obtained
