3D Laser scanning is a method of collecting literally millions of points on the surface of an ojbect. Light emitted from the laser is reflected back and is timed and the distance is calculated to generate an x,y,z coordinate point. The Nikon LC15Dx is the most accurate laser scanner on the market and its smaller field of view perfectly suits digitizing compact or detailed objects with higher point density and tighter tolerances of +/- 2.5 microns.
The gathered points (point cloud) can be fused together to create a mesh which can then be used in a number of ways:
- Compare to the original CAD file
- Geometric Dimension and Tolerance (GD&T)
- Surface Modelling
- Reverse Engineering
- Mobile Mapping
- Large Building
Crime scenes are a good example of how quickly and urgent 3D laser scanning can benefit. Loss of any crucial evidence can be avoided more efficiently with this process. A detailed 3D point cloud overlay can be recorded by scanning the crime scene which will reduce the risk of deterioration.
Once the site has been Scanned forensic scientists can examine the scene before it was compromised.
