When an existing facility is being modified or
upgraded, Hi-Cad will capture 3D laser scan data on site and supply
in a format that seamlessly enters the customers engineering work processes.
Hi-Cad uses a fleet of high speed scanners which send a laser light
beam out in the horizontal and vertical directions to measure points at up
to 500,000 times per second. This results in laser scan data with high
photographic quality which can then be used for planning new work.
When laser scanning on site it is vitally
important to link all the laser scans together very accurately using
DIMES. This
method of plotting a survey grid is the most accurate and using this
approach we can double or treble the data output when compared to the
existing data being used by our customers.
