  The coordinate measuring machine(CMM) has been the benchmark of accuracy in
measuring solid objects from nearly past 50 years or more. However with the
advent of 3D scanning technology, the accuracy and the density of point cloud
generated has taken over. In this project we not only compare the different
algorithms that can be used in a 3D scanning software, but also create our own
3D scanner from off-the-shelf components like camera and projector. Our
objective has been : 1. To develop a prototype for 3D scanner to achieve a
system that performs at optimal accuracy over a wide typology of objects. 2. To
minimise the cost using off-the-shelf components. 3. To reach very close to the
accuracy of CMM.
