Church Scanning Project
The GKS team used the Faro LS-880 to document the existing interior of a
58 year old church building. The original blueprints had been lost
long ago, and accurate measurements were needed prior to the start of
possible building renovations. Built with neo-gothic style
architecture, the church has a unique cross-shaped nave. Due to
the high vaulted ceiling, massive wooden beams, and wide variety of
colors and materials inside the church, obtaining accurate measurements
with other types of digitizing equipment would not have been time or
cost justifiable.

Photo 1: The image above shows one entire
360° scan taken with the LS-880. The distorted view is due to the
360° spherical scan being stretched and flattened out for viewing
purposes. This is similar in nature to “peeling” the spherical map
from a globe in order to produce a flat map. While the image
resembles a simple black and white photograph, it is actually made up of
the hundreds of thousands of individual X, Y, Z data points collected by
the LS-880. |

Photo 2: The image above shows a partial
scan. The distortion is again due to the “flattening” effect
mentioned above. Note that this data, as well as that in photo 1,
is a result of the laser scanning process, and is not based on the use
of any sort of camera. The laser actually records the light value
of the objects it scans and assigns a grayscale value to each collected
data point. |

The image above shows the color version of the same scan data as in
photo number 2. Through the optional attachment of a digital
camera, the LS-880 can assign true color values to the points rather
than the standard grayscale value. Again, while this image appears
to be a digital photograph, it is actually a colorized set of point data
that is fully measurable. |

Photo 4: The image above shows just some of
the raw 3D points within the Faro software. Through scanning from
multiple positions, the entire church interior was scanned within one
hour. |
