Advances in high end professional
digital cameras and software are revolutionizing industrial close range
photogrammetry. The extreme portability of a handheld camera
makes it possible to collect data quickly, and in
locations where larger instruments are not practical. The simplicity
of this system makes it one of the easiest metrology systems to learn and
use. The DPA-Pro is the ultimate portable CMM.
The DPA-Pro system uses digital images which are analyzed automatically
to report 3D locations of targets which have been placed on the object of
interest. Targets can be magnetic or adhesive backed to allow fast
placement. A variety of target designs allows the user to tie in to a
coordinate system.
Data can be compared before and after the
object has been subjected to load or changes in
environmental conditions. Targets are identified, image
quality analyzed, camera calibrations
obtained, and results reported with minimal user interaction.
Feedback is provided to allow the user to determine the quality of
data and quickly optimize results of the measurement process.
The DPA-Pro
industrial photogrammetry system has been optimized to allow the use of the
latest developments in professional digital camera design.
Commercially available high end commercial grade digital cameras have
evolved to the point where they can produce excellent results giving the
user a first rate metrology system at good value.
Camera
Selection:
The Nikon D2X
has been selected as the base level camera for use with
the Aicon DPA Pro Photogrammetry Systems. This is a highly acclaimed and
well proven professional grade digital camera. It has a stable, rugged
magnesium alloy body and uses a high quality Nikon lens.
The D2X CCD image sensor captures a 12 megapixel image The Nikon D2X has a stable alloy body and the very good
image quality.
