In order to use photographs in a computer environment, they
must be converted into digital format. There are several ways
to convert photographs into digital format: they can be obtained
directly from a digital camera or scanned
into the computer using a scanning device.
Once in digital format, the photos can be enhanced for printing,
or imported into specific software package for dimension extraction
(Photogammetry). Specific areas in the photo can then be highlighted
Photogammetry is the process of extracting dimensions
from two-dimensional photographs. The object(s) from which
dimensions need to be extracted must appear in more than one
photograph and viewed from different angles, preferably from
ninety-degree intervals. A lot of pictures do not necessarily
mean that you have more information to extract -- it is the
way the photos are taken that is most important.
Gen-Tek knows the intricacies in taking survey photographs
of objects for the purpose of extracting dimensions. We can
evaluate your existing project photographs to see if they
meet the criteria for extracting dimensions. Many times we
revisit the event scene and take additional photographs and
measurements to augment the case's documentation and to expedite
the creation of the demonstrative evidence.
