Thomas Langley and Company is proud to announce the acquisition of the 6^th of these scanning laser units introduced into this country, and the first used in the field of accident reconstruction.  Originally designed to measure very minute changes in the nuclear cores of radioactive power generators in France, this technology has evolved into the Accident (Crash) Reconstruction Industry.  The goal of TLC in purchasing this very expensive and highly accurate piece of equipment is to be able to provide highly accurate measurements of crash vehicles to attorneys representing different parties in litigation.  TLC is not and has never been aligned with either side of litigation.  I choose not to do Criminal Defense work but that is my personal choice.  I am happy to perform professional services to either side in a civil litigation.  This scanner will ultimately allow Rapid Prototype Models of crashed and exemplar vehicles in litigation to aid the trier of fact in determination.

 

 

 

 

 

 

 

 

 

 

A scanning laser is set up aligned to the test vehicle and calibrated with registered targets.  Once a scan is concluded, the unit is moved to a different location and is registered to the spherical targets. Scanning of the 4 sides, top and bottom if necessary is done.  The Mensi GS100 Scanning Laser picks up 5000 points per second as it scans..  It can be set for extended accuracy through averaging and is accurate to 6 mm at 100 meters.  That is < 1/4 inch at 325 feet.  Scanners are used to pick up and record point clouds.  Point Clouds are groupings of data points recorded in x,y,z coordinates.  The Mustang below was scanned at moderate resolution by the Mensi GS100 Long Range Scanner which recorded 3.2 million data points.

The Scanner collects points on the vehicle analogous to an MRI on a body.  It uses a visible Class 2 Laser green laser as it scans vertically along the vehicle in whatever incremental grid established by the operator.  Most operations can be properly done with a grid spacing of 5 mm.  With averaging set fairly high at 18 shots per point a finely detailed point cloud can be established.  Once scanned and recorded the vehicle can then be meshed and surfaced.

 

 

 

 

 

The Mensi GS100 Long Range Scanning Laser also takes a digital picture of the vehicle as it scans.  This photograph can then be wrapped around the recorded points giving a 3D image appearance.  The difference between taking a 3D scanned vehicle with a wrapped digital picture is like having your vehicle living in the computer in a 3d area.  You can rotate it, front back sideways in any orientation.  This can be transferred out as a dxf to be used in animation or simulation software.  It can be saved as images, objects or most excitingly transferred out to a Rapid Prototyping System for a true scaled model.

 

 

 

 

Here is the Mustang that was scanned and measured using this new technology.
