cases where process control has been established within 
a routine maintenance program it may be acceptable to 
continue the burning process until the machine stability is 
verified. Many times when production is in full gear the 
notion is leave equipment alone for as long as it works 
because work stoppages are too costly. This has 
discourage any thoughts that routine (preventative) 
maintenance equates to work stoppages and is costly. 
4.0 CONCLUSIONS 
Digital Close-Range Photogrammetry is a powerful and 
emerging technology functioning quite well in the deman- 
ding shipyard environment on daily basis. Seasonal 
variations in temperature have been of little consequence 
for measurements to date provided the camera has been 
acclimated to environmental surroundings. Neat cut 
measurements have been obtained in temperatures 
ranging from -10 to +100 degrees Farenheit. The speed 
of obtaining images and measuring off line is well 
appreciated at these extremes. Also important is the 
portability and ability to work on unstable platforms 
ensuring the least possible impact to surrounding 
production work is a decided advantage over existing 
measurement systems. The use of DCRP methodology 
to compliment traditional equipment and techniques has 
led to faster data turn around, improved accuracy, higher 
productivity, and increased safety as provided in the 
application discussions. There are many other areas of 
applications for Digital Technology. (One that can be 
mentioned briefly is the use of images for Ship Checking. 
Here the user has the ability to use the image as a 
documentation tool or import it into CAD software for 
dimensioning purposes...) This paper has covered the 
use of vendor purchased DPMS utilizing KODAK DCS 
4xx mi series of cameras. The use of other digital 
components and software combinations (Gruen 1994) 
ike video cameras, frame grabbers, surface 
reconstruction, etc are very attractive for measurement 
pur-poses. To date not much of this aspet of Digital 
technology has been tested in the Shipbuilding Industry. 
The potential is out there provided the 
researcher/developer keeps the functionality of a 
measurement system at a level that encompasses a wide 
range of users.
