depicting a crime scene. Digital forensic photogrammetry can also be used
by forensic specialists to make specific 3D measurements of actual scenes
and objects directly from photographs that are to be used as evidence in
court. Photogrammetry can discover any object that is identical in two or
more photos, and then measure any object in the picture. This enables a
scene from the place of accident to be re-enacted after some time.
Photogrammetry also has the capability to orientate three dimensions
objects accurately for camera misalignment. Since the exact measurements
can be produced, the scene is easily depicted through a computer model
integrated with all spatial relationships correctly for being shown in
court. The usage of digital photogrammetry in crime scene analysis has not
really changed on-scene photography procedures for photographers.
Sometimes, evidence found at the site of the aviation disaster can
require the interpretation of scientific analysis. Failures of propulsion
systems, landing gear or flight control structures, fractures in
crankshafts, engine rods or turbine fan blades, abnormal aircraft speeds or
flying operations are just some areas that are thoroughly investigated
after an aircraft accident. They are also categorized under the scientific
The investigating team believes that accidents are never really the
same type. In every accident there are new issues that have to be dealt
with, and consequently require the understanding of new technologies to
The different questions often posed by the investigators can include:
what was the form and sequence of failures' Did the components fail to
perform according to their specifications'; Were the mechanical settings at
the time of the accident incorrect'; what is the result of ...
