What is 3D Scanning?
Laser scanning constitutes the deflection of laser beams. 3D Scanning Services involves the process of analyzing real-world objects for data collection. The collected data is then used for constructing digital 3D Models, consisting of a polygon mesh or point cloud of geometric samples on the surface of the object. The points are then used to extrapolate the shape of the subject called reconstruction. The volumetric technique helps multi-sampling and data compression. To create digitized 3D models, structured light 3D scanners, LiDAR and Time of Flight 3D laser scanners as well as industrial computer tomography scanning are used. A non-contact interferometric technique is also utilized for surface digitization, presenting advantages over other optical techniques like laser triangulation. 3D data acquisition, as well as object reconstruction, is often executed through a photogrammetric technique based on a block of overlapped images.

Technology Used for Laser Scanning:
- Scanning mirrors:
- Moveable light-weight mirrors for steering laser beam, with reflectivity of 99.5%, mounted on the galvanometer.
- To position two-dimensional laser beams,the mirror rotates along axesfor scanning systems, reflecting laser beam onto closely spaced mirrors mounted on orthogonal axes.
- Piezoelectric actuators or magneto strictiveactuators are alternatives in this regard, providing higher angular s However, they come at the costof smaller achievable maximum angles.
- Microscanners/MEMS devices having smallmirrors with controllable tilt are used in pico
How much does 3D Laser scanning cost?
The cost of 3D Laser scanning process ranges from like a hundred dollars for a small part of an object to thousands of dollars for a large and complex building project. The estimate offered to you is based on two major factors:-
Size or area to be scanned, and
Complexity of the construction project.
The cost estimate given by any company is exclusive of other additional costs such as the cost of reverse engineering and dimensional inspection. A separate amount is incurred if any additional service is availed.
FAQ's
3D Laser Scanning Works on the Principle of Time of Flight. The Camera Emits Laser Rays That Incidents on a Surface. The Distance From the 3D Camera to the Surface Is Calculated by the Sensors Embedded in the Scanner. This Distance Is Also Known as the “time of Flight”. The Coordinates of the Surface Targeted by the Laser Rays Is Calculated. This Data Is Known as Point Cloud Data, Which Is Further Processed to Create a Three-dimensional Digital BIM Model in Software Such as Autodesk Revit.

Raw data scanned from actual objects such as building exteriors and interiors, process plants, topographies, and manufactured items is used to create point clouds. The raw data utilizing LiDAR technology enabled 3D laser scanner are transformed into readable point cloud files. Raw scan data is converted to scan files (RCS files) and Reality Captured project files (RCP files) that reference multiple RCS files by Autodesk ReCap. Both of these formats are compatible with AutoCAD and Revit software.
