For the purpose of generating 3D models of large and complex objects, if we manually do measurements then it will be very much hard and even time taking and also requires different instruments for measuring the complex objects. After spending time on manually measuring it is possible that it will not be accurate due to various problems such as human error. To deal with these problems we have proposed an idea to develop a device that can do these all things automatically and quickly. The problem of accuracy has also been solved as there is minimum human intervention. A 3D model of the target object will be generated and further it can be used for any other application where it is required.
