Advances in technology have dramatically improved quality and lowered costs for industrial automation engineering companies that design and build manufacturing facilities.
One of the latest advances is 3D laser scanning. The 3D laser scan is used to capture data information on existing structures, equipment, utilities, or manufacturing processes. 3D scanning will capture dimensional information on any existing objects or surfaces. Once this data is acquired, a point cloud is generated and used as the background or basis for a design.
Similar to a Total Station, a 3D scanner projects a laser onto a surface, which is then reflected back to the scanner. The scanner will analyze and compare the differences in reflected light frequency and the phase shift of the reflected wavelength to determine the object’s position in space.
The 3D scanner contains an internal mirror that rotates vertically in a full circle. In addition, the scanner will rotate horizontally in a full circle. This combination of a vertically- rotating mirror and horizontally rotating scanner produces a 3D point cloud in a sphere emanating from the scanner.
