Dear REL
If you can get the proceedings from the TCT conference (Cardiff England) of
this year ( www.time-compression <http://www.time-compression> .com), there
was a case study presented by Westland Helicopters for large, low accuracy
assemblies and prismatic components. The actual accuracy is up for debate
but it is likely to match your 4mm tolerance. The case study details
photgrammetry using digital photographs and predetermined datum's etc. It is
an approach which has come out of the civil engineering world (large
structures) and is often used by the oil industry for refineries etc.
If this draws a blank, send me a more detailed mail and I'll try and help
Best Regards
Chris Lawrie

Subject: Large Object Scanner
One of our clients has the need to scan objects up to 4 meters by 2 meters
in
size with a resolution of 4 mm. Desired processing time for inputting of
data and creating a CAD file is one hour.
What candidate systems are out there that can meet these requirements?
Best Regards,
REL
