The purpose of this development is to create a 3D volume calculating device for the industrial use to acquire the huge volume of the ultra large-sized scrap or the highly piled-up discarded metal material in the factory. Considering the specific working conditions in this research, the design concept of the system configuration hence focuses on the industrial advantages which include those of a small and portable volume, a detachable mechanical structure, a relatively lower cost and a more apt way of control. By combining the 3D scanning technologies with the following components of the...
