Application Area
 

Within a few minutes the Z+F measurement system
can provide accurate measurement data of crime scenes
and accidents - outdoor and indoor.
These data enable a fast investigation support for
"freezing" the scanned crime scene and for documenting it.
These evaluations are judically accepted.

Accident
Measurement
 

The laser measurement systems of Z+F enable an
accurate three-dimensional capture of the complete
accident scene with all the details like deformations of
the vehicles or skidmarks. Using this technology, the
question of the possible causes and sequence of the
accidents can be analysed and answered more easy.

Crime Scene
Measurement

 

The complete securing of evidence at crime scenes and
the geometrical capture on the spot are essential for the
following procedure. The crime scenes have to be captured
from various locations of the IMAGER and connacting these
scans, the viewer gets an overview of the complete scene.
The Imager can be used so flexible, that it can work even in
the smallest spaces (e.g. under a chair) without any
problems. On the spot at a crime scene, 3D-plans, ground
plans, horizontal and vertikal slices or only views of the
point clouds can be provided.

3D Suspect
Measurement

 

Visual Sensor Fusion (VSF) software developed by the
Dutch company DelftTech BV can combine 3D point clouds
with 2D images (pictures of a surveillance camera). A virtual
person can be set into the point cloud and using the 2D
picture, it can be adopted to it. In this way, the user is
capable to determine the length of a person with the desired
accuracy. One of the benefits is the fact that a suspect
must not stand erect and an other one is the immense
saving of time.
